port used to connect an N_Port (host connection). The FL_Port is the Fabric access port used to connect

NL_Ports to the switch in a loop configuration.
Refer to "Sample Fabric Topologies

" for some sample Fabric topologies.

Expansion Connections (E_Port)

Expansion (E_Port) connections are used to interconnect switches within a Fabric. Refer to "Sample Fabric

Topologies" for sample topologies using different E_Port connections to create different Fabric topologies.

Host and Target Connections (N_Port/NL_Port)

The connections to the Fabric are through Nx_Ports. Refer to "Sample Fabric Topologies" for examples of
various hosts and devices connected to Fabrics via their N_Port connections. The N_Port (host connection)
connects to the F_Port (Fabric connection). The NL_Port (arbitrated loop configuration) connects to the
FL_Port (Fabric connection).

Ethernet Connection

Connecting an existing Ethernet 10BaseT local area network (LAN) to the switch via the front panel RJ-45
connector gives access to the switch's internal Simple Network Management Protocol (SNMP) agent,
allowing remote Telnet and Web access for remote monitoring and testing.

NOTE: The connection is only for Telnet, SNMP agent, and the Web-based server access. No Fabric connection is

available via this connection.

Serial Port Connection

The PowerVault™ 50F Switch includes a serial port (see Figure 1-7) used to set the Internet Protocol (IP)
address. The serial port is used to set the IP address when setting up or reinitializing a switch. The serial port
settings are as follows:

8 bit
No parity
One stop bit
9600 baud
Hyperterminal
VT100
Flow control = Xon/Xoff

Installing the PowerVault™ 50F Switch: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

NOTE: The serial port and Telnet connection are mutually exclusive and there can be only one serial port session active at

a time. Telnet takes priority, so the serial port is terminated when a Telnet connection is made. The serial connection is
restored after the Telnet session is completed, but you must log in again. A password is required to log in to the serial
port session. Password checking is skipped only at initial power on and remains off until log off is done.

System Configurations

In order to communicate with the RS-232 port, a computer system is required with the following:

Hyper terminal
An available COM port

Cables: A straight-through serial cable (DB9 female-to-female) connected between the DB9 serial
ports on the computer and switch. See Table 1-2 for pinout requirements. This cable is included in the
over-pack, shipped with your PowerVault™ 50F switch.

Serial Cabling and Emissions Requirements

The PowerVault™ 50F Switch uses a straight-through serial cable with a female 9-pin D-Subminiature
connector with the pinouts shown in Table 1-2. Only pins 2, 3, and 5 are required.

Table 1-2. Cabling Pinouts

Installing the PowerVault™ 50F Switch: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Verifying Power-On Self-Test (POST)

When powering on a switch, the switch conducts a series of diagnostic tests including:

Memory Test
Port Register Test
Central Memory Test
RDRAM Test

As the POST successfully performs each of the tests, the message Passed is displayed via the local RS­232 serial port.

After the switch completes the POST, the GBIC module returns to a steady state from the flashing states
shown during the tests.

If an amber GBIC module light is displayed, there was a failure on that port during POST. See "Power-On

Diagnostics" for details.

If error conditions are encountered, they are displayed on the local RS-232 serial port after the switch
completes the POST. See "errShow" for details.

Setting IP Address Using the Serial Port

There is a label on the front panel of the PowerVault™ 50F Switch with IP address and space to include the
IP address when it is configured.

NOTE: This label facilitates identification of the physical switch in maintenance mode.

The serial port is initially logged on as Admin with no password required.

Regardless of the topology used, the switch's extremely low message latency minimizes Fabric message
handling time that results in a high-performance Fabric.

Routing Cost

All Inter Switch Links (ISLs) have a default cost of 1000. The cost of a path between any two switches in the
Fabric is the sum of the costs of all ISLs. The switches that comprise the Fabric always choose the lowest
cost path through the Fabric to forward frames from the source switch to the destination switch.

When constructing a multiswitch configuration, called a cascaded Fabric, a frame entering the Fabric may
pass through eight switches before exiting the Fabric. The switch does not enforce the eight-switch limit. It is
your responsibility to ensure that the seven-hop limit is not exceeded. The command uRouteShow provides
information regarding the cost of the shortest path to another switch from which you can derive the number
of hops. The cost should not exceed 7000 (7 x 1000).

A Fabric using Dell switches in cascaded topologies should be configured to deliver the required bandwidth
and fault tolerance with all connections made within the seven-hop maximum limit.

Configuring Switches

When configuring switches in a Fabric, optimize the Fabric performance based on the most significant
expected use.

NOTE: Except for unique identifiers such as the switch name, domain name, and IP address, all switches in a Fabric must

have the same firmware configuration. Switches that are configured differently are isolated from the Fabric.

Cascaded topologies using multiple switches give switching system designers a powerful, flexible set of
resources to create high-performance, robust storage area networks (SAN), or data center backbone.

Loop Support

The FL_Port interface card enables any Fabric-connected device to communicate with public or private fibre
channel disks or other device types.

NOTE: Loops may contain any combination of public or private loop devices.

Public Operation

In public operation, all loop devices are accessible to all other Fabric-connected devices and loop devices
within the Fabric. The loop devices behave the same as devices attached directly to the Fabric.

Private Operation

Dell's FL_Port translative mode allows private devices on a local loop to communicate with Fabric-attached
devices and vice versa. Fabric-attached devices can be either N_Ports attached to G_Ports or public
NL_Ports attached to other FL_Ports.

Logically, private and Fabric-attached devices that communicate to a loop appear to be devices on the same
loop as the private devices. Each Fabric-attached device uses an unassigned AL_PA from the local loop.
When private devices on a local loop and Fabric-attached devices communicate, the FL_Port automatically

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/POWER.HTM[3/15/2013 11:31:57 AM]

PowerVault™ 50F Topologies: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

translates between private and public addresses.

The FL_Port translative mode supports up to 32 Fabric-attached devices (one is reserved for the Fabric)
appearing on each local loop of private devices, subject to the limit of 126 devices on a loop (the total of
private and Fabric-attached devices).

Private devices are registered to the Simple Name Server (SNS), so the Fabric-attached devices can query
SNS for their addresses and initiate communication.

NOTE: The translative mode is automatically enabled with the FL_Port card and no user intervention is necessary to

configure the translative mode.

Sample Fabric Topologies

The following Fabric topology samples show several different conceptual topology models. Each installation
has a unique topology that is determined by the characteristics of the connected devices and your
performance objectives.

In the following samples, only the single switch Fabric solution shows connections to the Fabric. The switch
numbering scheme is:

Interface cards 1 2 3 4
Ports 0 2 4 6

1 3 5 7

Single-Switch Fabric

The simplest Fabric consists of a single-switch topology as shown in Figure 2-4.

Figure 2-4. Single-Switch Topology Sample

Figure 2-4 shows the switch's F_Ports and FL_Ports and the corresponding N_Port and NL_Port
connections on the device side. The switch connections are shown as they would be in a physical

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/POWER.HTM[3/15/2013 11:31:57 AM]

PowerVault™ 50F Topologies: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

installation. Functionally, the switch becomes a Fabric with every device connected to every other device by

the Fabric.
Each connection is full duplex with transmissions up to 1 Gbps bandwidth simultaneously, in both directions,

between the Fabric and Fabric-connected devices.

Two-Switch Sample Topology

The two-switch topology increases the number of connectivities and aggregate Fabric bandwidth, as shown
schematically in Figure 2-5. The switches are shown physically connected although the connections are
transparent in the Fabric. Functionally, the devices appear to be connected together directly.

Figure 2-5. Fabric Topology Sample With Three Connections Between Two Switches

When a Fabric is initiated, or when a new switch is added to the Fabric, the switches determine a least-cost
path for each destination switch. This is done dynamically each time the Fabric configuration changes and
the results are stored in the switch's internal routing tables.

NOTE: After a path has been determined, it is not rerouted, even though traffic volume may change over time, for each

path to maintain in-order delivery. If the link fails, the path is rerouted.

Increasing Local Bandwidth within the Fabric

In Figure 2-5, three connections are shown between Switch A and Switch B. This gives an aggregate
bandwidth of six Gbps - three 1-Gbps, full-duplex connections. Increasing bandwidth between switches is
done by adding additional connections between the switches.

In addition to the bandwidth, redundant connections between the switches in Figure 2-5 provide a high­bandwidth, fault-tolerant Fabric.

Four-Switch Sample Topology

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/POWER.HTM[3/15/2013 11:31:57 AM]

PowerVault™ 50F Topologies: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Figure 2-6 shows a four-switch topology that adds additional paths to the Fabric topology, increasing the
Fabric's reliability, bandwidth, fault tolerance, and connections.

Figure 2-6. Four-Switch Fabric Topology Sample

For example, the shortest path between switch A and switch D would be the direct path AD. If this path were
to fail, the connection would then be automatically routed through either switch B or C with a path of ABD or
ACD.

In Figure 2-6, ports 6 and 7 on the interface module in position 4 of switch A are used for connection to
switch B and switch D. If the interface module failed, traffic to switch B, C, and D would all have to be
rerouted between the interface modules in the third position on switches A and C.

A more robust solution is to have all connections distributed across available interface cards in each switch,
giving an alternate configuration as shown in Figure 2-7.

Figure 2-7. Four-Switch Fabric Topology Sample

If bandwidth or fault tolerance is a concern, each of the paths shown in Figure 2-7 could have a parallel
connection.

Overview • Comparing Switch Management Methods • Managing Via Telnet • Managing with SNMP Under
Dell OpenManage™ and the PowerVault™ 50F Switch Manager

Overview

This chapter contains general information and examples on managing and monitoring the switch. The
following are discussed:

Switch management methods
Managing via Telnet
Managing with SNMP under Dell OpenManage™ and the PowerVault™ 50F Switch Manager

NOTE: You must assign an Internet Protocol (IP) address to the switch via the local RS- 232 serial port before you can

access some of the management methods described.

Comparing Switch Management Methods

The switch is managed locally via a computer running a terminal program attached to the RS-232 serial port
and remotely via Telnet or Web management (PowerVault™ 50F Switch Manager).

Before changing any of the factory default settings, become familiar with the operations described in this
chapter including both the switch's functions and interactive characteristics. To reset a switch to factory
default values, see "Resetting Factory Defaults

There are several access methods for managing a switch. Table 3-1 summarizes the different management
methods.

information.

Figure 3-1.Methods for Managing PowerVault™ 50F Switch Information

Managing Via Telnet

To make a successful Telnet connection to a switch, the following is required:

Switch name or IP address
Username
Password

NOTE: The IP address must be set using the ipAddrSet command, which can be issued by connecting to the RS -232

serial port on the front panel. See "Setting IP Address Using the Serial Port
Consult with the local network system administrator for the IP address that is assigned to the switch.
The serial port and Telnet connection are mutually exclusive and there can be only one serial port session active at a time.

Telnet takes priority, so the serial port is terminated when a Telnet connection is made. The serial connection is restored
after the Telnet session is completed but re-logging in is required. A password is required to login to the serial port
session. Password checking is skipped only at initial power on and remains off until log off is done.

Default Username

Each Username has a security level associated with it. Username 3 is the least privileged and the security
level goes up to Username 0, which is the most privileged.

performed at this level.

The system administrator may assign different usernames than those listed, if desired. The user at a
particular security level, however, has the same privileges regardless of the name assigned.

Changing Passwords

The initial default password for all usernames is password. Change the default passwords during
installation to meet the Fabric's security requirements.

To change user passwords, perform the following steps:

1. Log in as admin.

2. Issue the command passwd.

3. Each username (admin, user, other) is displayed in sequence, allowing the admininstrator to modify
each password and name.

4. Enter a password or name while a username is displayed to replace the existing password or name.

NOTE: If you lose the password, contact Dell Technical Support.

Managing with SNMP Under Dell OpenManage™ and the PowerVault™ 50F Switch
Manager

The resident SNMP manage node allows remote switch management via IP over Ethernet and Fibre
Channel interfaces.

Dell Openmanage integrates the PowerVault™ 50F Switch through HP OpenView Network Node Manager
Special Edition (NNM SE) in a Windows NT environment. You can use Dell OpenManage™ to manage this
device. If you have a PowerVault™ 50F Switch connected in your network, it will be automatically discovered
as a node in the node submap of HP OpenView NNM SE. In order to launch the PowerVault™ 50F Switch
Management Application, double-click on the discovered FC-Switch node to access the expanded node
submap, and then double click on the Switch Management Application icon.

Refer to your HP OpenView Network Node Manager Special Edition 1.4 with Dell OpenManage™ HIP 3.4
User's Guide for more information on Dell OpenManage.

The switch's manage node supports the following:

SNMPv1 manager
Command line utilities to provide access to and command the manage node
MIB-II system group, interface group, and SNMP group
Fabric Element MIB
Vendor-Specific MIBs
Standard Generic traps

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/MANAGE.HTM[3/15/2013 11:31:58 AM]

Managing the PowerVault™ 50F Switch: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

SNMP Transports

The SNMP manage node residing on the embedded processor supports UDP/IP over the Ethernet interface
or any FC-IP interface (see Figure 3-1

). This transport provides an immediate Plug and Play support for the

switch once the IP address has been assigned.

MIB-II Support

There are eleven groups of objects specified in MIB-II. The switch's SNMP manage node supports three of
these groups. The eight additional groups do not apply.

The three groups supported include the following:

System group (object ID is {iso, org, dod, internet, mgmt, mib-2, 1})
Interfaces group (object ID is {iso, org, dod, internet, mgmt, mib-2, 2})
SNMP group (object ID is {iso, org, dod, internet, mgmt, mib-2, 11})

The following variables are modifiable via the SNMP set command, given an appropriate community with
read-write access.

sysDescr System description: the default value is set as Fibre Channel Switch
sysObjectID System object identifier vendor's authoritative identification (1.3.6.1.4.1.1588.2.1.1.1)
sysUpTime The time since the manage node was last initialized
sysContact The identification and contact information for this system. By default, this is set as Field Support.
sysLocation The node's physical location. The default setting is End User Premise .

The interface group supports three interface drivers: software loopback, Ethernet, and Fibre Channel IP. Dell
is not currently supporting Fibre Channel IP.

Fabric Element MIB Support

The following five object groups are defined:

Configuration group
Operation group
Error group
Accounting group
Capability group

The manage node supports all groups.

PowerVault™ 50F Switch Vendor Unique MIB

The following five object groups are defined:

PowerVault™ 50F System Group
Fabric Group
SNMP manage node Configuration Group
Fibre Channel Port Group

Managing the PowerVault™ 50F Switch: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Name Server Group

Generic Traps

Setting up the switch's SNMP connection to an existing managed network allows the network system
administrator to receive the following generic traps:

coldStart — indicates the manage node has reinitialized itself such that the manage node's
configuration can be altered.
warmStart — indicates the manage node has reinitialized itself, but no configuration has changed.
linkDown — indicates an IP interface (Ethernet, loop back, or embedded N_Port) has gone down and is
not available.
linkUp — indicates an IP interface (Ethernet, loop back, or embedded N_Port) has become available.
authenticationFailure — indicates the manage node has received a protocol message that is not
properly authenticated. This trap, by default, is disabled but can be enabled via the command

agtcfgSet

Enterprise Specific Traps

Three Enterprise Specific Traps are supported:

swFault — indicates that the diagnostics detect a fault with the switch.
swSensorScn — indicates that an environment sensor changes its operational state (for example, a fan
stops working). The VarBind in the Trap Data Unit contains the corresponding instance of the sensor
status.
swFCPortScn — a notification that a Fibre Channel Port changes its operational state (for instance, the
Fibre Channel Port goes from online to offline). The VarBind in the Trap Data Unit contains the
corresponding instance of the port's operational status.

NOTE: SNMP swFCPortScn traps are generated on GBIC insertion and removal even though the state remains offline.

Manage Node Configuration

Changes to SNMP from either Telnet or SNMP are not displayed in SNMP until the switch is rebooted
running. This is due to SNMP running from cache while the active settings are running from the flash PROM.

The configurable parameters include the following:

SNMPv1 communities (up to 6)
Trap recipients (1 per community)
sysName
sysLocation
authenticationFailure — indicates the manage node has received a protocol message that is not
properly authenticated. This trap, by default, is disabled but can be enabled via the command
agtcfgSet.

The sysX parameters can be configured via the SNMPv1 SET command with an appropriate community.
These parameters can be configured via a Telnet connection, using the command agtcfgSet.

NOTE: A change in the first two configuration parameters takes effect only after rebooting the switch.

Managing the PowerVault™ 50F Switch: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Name Server

The fibre channel protocol (FCP) inquiry data obtained by device probing may now be obtained from the
Name Server by retrieving the port symbolic name.

Common Transport (CT) requests and responses including Name Server are recorded in the portLog. A
typical trace is shown as follows, where port 4 logs in to the Name Server and issues command 217. It
receives an Accept (8002).

Overview

Use the PowerVault™ 50F Fibre Channel Switch Manager (Web interface) to log onto a switch from a host
with a Java-enabled Web browser via the Internet or Intranet to remotely manage a Server-Storage Area
Network (SAN) composed of switches and other SAN devices. PowerVault™ 50F Fibre Channel Switch
Manager allows you to dynamically interact with any switch in the SAN to monitor status and performance.
You use the available information to make overall topology decisions (for example, increasing a path's
bandwidth due to data saturation). Additionally, you can change a switch's configuration or download
firmware. The Administrative Interface and Telnet provide the means to make administrative changes, and
security is enforced by username and encrypted password.

This chapter discusses the following information about managing and monitoring a switch using
PowerVault™ 50F Fibre Channel Switch Manager:

Switch Management Tools

The management tools provide five screens, as described in the following subsections.

Fabric View Page

The Fabric View Page shows the number of network switches and confirms worldwide names, domain IDs,
and switch names, if applicable.

Fabric Topology View Page

The Fabric Topology View Page shows the physical configuration including active domains, paths and
routing information. For example, the hop count which is the number of switches that handle a data frame
from origination through to the destination.

General Switch View Page

The General Switch View Page displays switch enclosure information, confirms general switch information,
and includes GUI buttons for quick access to the Administrative Interface, Telnet, and the Performance View.

The front panel identifies the type of interface module installed in each switch slot, the industry media (GBIC,
or Gigabit Interface Converter) used by the ports, and each port's light-emitting diode (LED) status. From this
view, more information is available about the switch by moving to either the Performance View or the Port
Detail View.

Introducing PowerVault™ 50F Fibre Channel Switch Manager: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Performance View Page

The Performance View Page graphically shows real-time data throughput for each port and switch bandwidth
utilization.

The two types of performance data shown are the throughput of each port and total switch throughput.
Bandwidth utilization is critical information needed to make decisions about optimizing performance, for
instance, if one port begins to handle a disproportionate amount of traffic.

Port Detail View Page

The Port Detail View Page shows statistics and general information for all ports, including LED status.
The Port Detail View appears for whatever port you select in the General Switch View. Once in this view,

every port for that switch may be viewed sequentially, by selecting its file folder. Each folder's tab replicates
the port's LED status which allows you to monitor all port status at the same time. Port details include
statistics about frames, interrupts, and errors that are helpful when troubleshooting.

Administrative Functions

The administrative functions provide two screens for secured interfaces, as described in the following
subsections:

Administrative Interface Page

The Administrative Interface Page is used to perform routine functions, such as upgrading firmware versions,
changing passwords, or switch reconfigurations.

Telnet Interface Page

The Telnet Interface Page uses Dell's superset of Telnet commands (configuration, diagnostics, displaying,
and routing) for switch diagnostics, troubleshooting, and management.

Using the Web Interface

The Web interface switch management system provides a Graphical User Interface (GUI) for users to display
Fabric topology, general switch information, port traffic statistics and throughput performance. The GUI
enables switch administrators to configure the switch and its ports.

Controlling the Web Interface

When you position the cursor over an object (such as a port or the thermometer) and click, an informational
screen is displayed. In some instances, you can change the definitions by completing text fields (see
"Administrative Interface Page

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/CONCEPT.HTM[3/15/2013 11:32:00 AM]

" for more information).

PowerVault™ 50F Fibre Channel Switch Manager Operational Concepts: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting ...

Fabric View Page

The Fabric View Page is the first Web page displayed (see "Fabric View Page" for details). This is a global
page and shows all switches present that comprise the Fabric. Note that switch in the Fabric can show the
overall Fabric view; therefore, it is not critical which switch is accessed initially.

The Fabric View Page uses switch names to connect to individual switches. This means you give each
switch a unique name (see Table 6-5 for information on how to use the switchName command), and this
name should match the correct Internet Protocol (IP) address by the name resolution protocol in use by the
Web client (NIS, DNS, etc.).

If a switch name is not recognized by the name resolution protocol, it may be accessed by typing in its IP
address from the Fabric View Page (double-click on the switch image while pressing down the <Shift> key
to open a dialog box and enter the IP address or host name).

Fabric Topology View Page

The Fabric Topology View Page shows the physical configuration, including active domains and paths, and
routing information (see "Fabric Topology View Page

").

General Switch View Page

The General Switch View Page shows a graphic representation of the switch's front panel (see "General

Switch View Page" for details). Normal long-term monitoring is conducted from this page, which provides a

real-time view of each switch's overall health and status in the Fabric. Note that if a switch has a problem, a
pop-up message is displayed explaining what problem has been detected.

Port Detail View Page

The Port Detail View Page provides statistics for each port (see "Port Detail View Page " for details). The
page features cascaded folders, one for each port. Each folder has a tab on the top to show the port number
and a status light to tell the port state.

Performance View Page

The Performance View Page displays port and switch throughput in bytes per second (see "Performance

View Page" for details). Each port is numbered and throughput for the entire switch is displayed under the

individual port readings.

Administrative Interface Page

The Administrative Interface Page is used to enable (or disable) the switch or ports (see "Administrative

Interface Page" for details). Change switch name, date/time, IP addresses, user name, passwords,

download flash, and reboot switch via this page. Only users with admin privilege can access this page. Any
changes made through this page may fundamentally change the switch/port status and its role in the fabric.

Telnet Interface Page

The Telnet Interface Page allows you to launch a Telnet session directly from your Web browser. Only

users with admin or user privilege can access this page, and the Telnet Interface Page is not in the help

menu. See the Dell PowerVault™ 50F Fibre Channel Switch User's Guide for detailed information and
supported Telnet commands. To launch a Telnet session click the Telnet button in the General Switch View

Page.

NOTES: Users with user (via Telnet) or admin level privilege can access these pages. The user level is more restrictive

and cannot perform configuration commands. The administrative page via a browser can only be accessed from the admin
level; all other accesses are rejected.

HotJava browsers do not support Telnet commands.

Overview

This chapter contains general information and examples on managing and monitoring the switch via the
PowerVault™ 50F Fibre Channel Switch Manager. The following topics are discussed:

Fabric View Page
Fabric Topology View Page
General Switch View Page
Port Detail View Page
Performance View Page
Administrative Interface Page

Fabric View Page

The Fabric View Page displays the switches in a grid. The lines between switches represent what the Fabric
knows about a switch, but do not indicate connectivity or how the switch is connected to the Fabric.

Double-click on a switch to display the General Switch View Page to provide additional switch information.
Selecting the Fabric Topology button displays a Fabric Topology View Page.

Fabric Topology View Page

The Fabric topology is viewed from the host domain (or host switch), which is initially requested from the
Web browser. This page is broken up into two figures and shows the physical configuration including active
domains, paths, and routing information (for example, the hop count which is the number of switches that
handle a data frame from origination to the destination). See Table 6-1 for field details.

The first item that appears in this page is a list of active domains (or switches) in the Fabric. Following the
active domain list is a table unfolding the views of active paths from the host domain to all remote domains in
the Fabric. This table is grouped by domains. The worldwide name and Internet Protocol (IP) address are
included under each domain. Each active path table displays host switch output port number, host switch
input port number, the hop count and metrics (costs) from the host domain to the remote domain, and the
path flag.

General Switch View Page

The General Switch View Page displays when you query the switch from the Fabric View Page (see Table
6-2 for field descriptions). A photographic quality switch is displayed on the browser. The switch picture
displays the ports, light-emitting diodes (LEDs), general switch information, temperature, fans and buttons
for administration functions, Telnet session, and performance view.

The admin button links to the system administration pages where you can disable/enable a port depending
on the appropriate authentication (see Table 6-5 and "Administrative Interface Page" in this chapter for more
information). The performance button links to the Performance View Page (see "Performance View Page
for more information). The Telnet button launches a Telnet session (see "Telnet Interface Page

").

"

Under normal conditions, the browser's lower-right corner holds animated thermometers and spinning fans.
The color and blinking speed of the port LEDs are updated every 1 to 2.5 seconds depending on the
operating system and browser used. Warning messages show up in a pop-up window automatically if
problems occur (for example, temperature exceeding maximum value, a fan stops rotating, or a port state
becomes problematic). Pushbuttons are placed in the bottom of the warning message pop-up window. Those
buttons are connected to a separate browser providing basic troubleshooting guides.

The thermometer indicates the highest temperature from the last data sample. Click on the thermometer to
display the temperature readings from all five switch sensors.

Table 6-2. General Information Fields

Field Description

On the left side of the display, the upper half shows port and LED status and the lower half contains general
switch information. Selecting the label on each text field displays a pop-up dialog that explains the field.

In the switch picture, the blinking green lights indicate problem status and solid black indicates no device
attached. Each port module is a clickable hyperlink that takes you to a third page, the Port Detail View Page
(see Table 6-3 and "Port Detail View Page" in this chapter for more information). Each port includes the port
number, a status LED, and port detail information.

If a port card is not installed, a solid black rectangle is displayed and the port status is indicated as No_Card.
If the interface is installed but no Gigabit Interface Converter (GBIC) is present, a silver rectangle is displayed
and the port status is indicated as No_Module.

If the port contains a GBIC, one of the following is shown:

For copper GBICs, a graphic representation of a copper GBIC with the letters "CU"
For shortwave fiber GBICs, a graphic representation of a GBIC with the letters "S" and "W"
For longwave fiber GBICs, a graphic representation of a GBIC with the letters "L" and "W"
If the port is on an arbitrated loop, the letters "F/L" are displayed in an oval between the ports
associated with the card.
If the port has failed, the port is outlined in amber to indicate a failure.

Timed_out Number of timed out interrupts.

Port Detail View Page

The Port Detail View Page features eight cascaded folders. Each folder has a tab on the top to show the
port number and a status light to tell the port state (disabled or enabled with the same light as described in
Table 6-3). The port information is updated once per second. However, the time interval may be as long as

2.5 seconds depending on the browser used. By monitoring the eight tabs, a system administrator can
evaluate each port state. The default top folder displayed on this page is for the port number checked from
the General Switch View Page. Clicking a tab brings the corresponding port folder to the front.

Below the folders is a pushbutton linked to the Administrative Interface Page (see "Administrative Interface

Page" for more information) where port enable/disable can be performed. A pushbutton is linked to the

Performance View Page (see "Performance View Page

" for more information) where port and switch

throughput data is plotted. A Done pushbutton is used to exit from the page.
Each port folder contains general port status information such as the port number, port type (E-Port, G-

Port), port WWN name, and some detailed information, such as the number of interrupts, number of link
failures, number of parity errors, number of time-outs, and the size of free buffer.

The LED located in the upper-right corner in each tab resembles the port LED in the switch front panel.

Table 6-4. Port Detail View Page Fields

Performance View Page

The Performance View Page displays port and switch throughput (in bytes per second). The first eight
graphs show the port throughput for port number 0 through 7. Throughput for the entire switch is displayed in
the long rectangular graph at the bottom.

The horizontal axis represents time elapsed. The port throughput graphs hold up to 60 seconds of
performance data. The switch throughput graph at the bottom holds up to 4 minutes of performance data.
The vertical axis in each graph shows throughput (in bytes per second). It is automatically scaled depending
on the switch activity. The display is updated roughly once per second.

The total throughput value is the throughput sum for all ports. The throughput number represents the number
of bytes received plus the number of bytes transmitted each second. Note that, because the switch also
transmits all data it receives, the total throughput for the switch could, alternately, be stated as one-half (1/2)
of the throughput sum of all ports.

Administrative Interface Page

Only users with admin privilege can access the Administrative Interface Page. Any changes made through
this may fundamentally change the switch/port status and its role in the fabric. Check and input boxes are
provided for you to type in the changes. Submit buttons are used to apply the changes. You can enable (or
disable) the switch or ports (8). Change switch name, IP addresses, user name, passwords, download flash,
and reboot switch via this page. Table 6-5 provides field information for the Administrative Interface Page.

PowerVault™ 50F Commands: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Figure 7-8 shows the fastboot command which is a warm reboot that bypasses power-on self-test (POST).

Figure 7-8. fastboot Command Example

flashDefault

Figure 7-9 shows the flashDefault command, which resets the switch to the factory default configuration
values.

This command may not be executed on an operational switch. You must first disable the switch using the

switchDisable command.
Figure 7-9. flashDefault Command Example

flashDefault also configures the switch to boot from its flash proms (removes any network boot parameters),

erases the SNMP database, and erases the Zoning database. If any changes have been made to the SNMP
configuration or Zoning configuration from the default values, then the factory default does not take effect
until the next reboot because the values are stored in cache.

For this reason it is recommended to always reboot the switch immediately after flashDefault.
flashDefault does not change the switches identity: Worldwide Name, Ethernet IP address and subnetmask,

gateway address, symbolic name, or license keys.
This command should be used with care; flashDefault restores the configurable parameters to factory

default values, as follows:

Switch modes: tachyon, isolated, notypes, nomcast, nopost
FC parameters: domain, BB_credit, RA_TOV, ED_TOV
FL_Port parameters: collection method, credit, FAN frames
Virtual channel parameters
syslogd IP address
Fibre channel IP address and subnetmask
Display error level
Original equipment manufacturer (OEM) customizing
Static paths
Usernames and passwords

flashDownload

Figure 7-10 shows the flashDownload command which is used to download firmware into flash memory.
This command can be executed on an operational switch. A reboot is required to initiate the new firmware
after the download has completed.

Firmware can be downloaded from either a UNIX

®

host, Windows® 95, or Windows NT host. For a UNIX

host, no special software is needed. For Windows 95 or NT, the Dell PowerVault™ Utilities Diskette provides

a daemon to support a remote shell (RSH). Firmware download is via RCP command running on top of TCP

between the switch and the host.
To download the firmware, perform the following steps:

1. Run the setup.exe file on the Dell PowerVault™ Utilities Diskette to install the rshd.exe and cat.exe
utility files on the hard disk.

2. Click Start and then click Programs.

3. In the program list, click Dell OpenManage™ PowerVault™ Manager—> PowerVault™ 50F Utilities
—> rshd.

The remote shell daemon starts. The cat.exe is run from the rshd.exe file

4. After rshd.exe completes the download, stop rshd.exe by pressing <Ctrl-C>. To minimize any security
exposure, the remote shell daemon should be terminated.

5. Start a Telnet session to a switch. The command format is:

telnet [switch IP address]

6. Log in as "admin."

login: admin

Issue the following command:

flashDownload ["host name/IP address"], ["user name"], ["filename"]

For example:

=> flashDownload "192.111.2.1", "johns", "/tmp/os/v1.6"

NOTE: The host name is the host name or is the host IP address, the username is a valid host username, and the

file name is a path to the new firmware file,

7. The RSH server validates the user and delivers the file to the switch where it is stored in flash memory,
as shown.

The first position a 0 shows and indicates that this virtual channel, assigned to handle internal switch traffic,
has the highest priority.
This priority value cannot be changed.
The second position, indicated with a 1, shows the priority assigned by the virtual channel link control.
The third through eighth positions can have only a 2 or a 3, indicating that the channel gives priority to either
Class 2 frame traffic or to Class 3 frame traffic.

transmission.
Time that this port cannot transmit frames due to a transmit buffer -to- buffer credit of zero.
Received data: the number of 8b/10b encoding errors that have occurred inside frame boundaries. This counter is

generally a nonzero value, although occasional errors may occur on a normal link and give a zero result.
(Minimum compliance with the link bit error rate specification on a link continuously receiving frames would cause
approximately one error every 20 minutes.)

Received frames: the number of CRC errors detected.
Received frames: the number of frames that were shorter than the minimum Fibre Channel frame size (i.e., a

header with no payload).
Received frames: the number of frames that were longer than the maximum Fibre Channel frame size (i.e., a

header with a 2,112 -byte payload).
The number of frames received with a badly formed end- of - frame.
Receive link: the number of 8b/10b encoding errors recorded outside frame boundaries. This number may become

nonzero during link initialization but indicates a problem if it increments faster than the allowed link-bit error rate
(approximately once every 20 minutes).

Receive link: the number of Class 3 frames discarded. Class 3 frames can be discarded due to timeouts or
invalid/unreachable destinations. This quantity could increment at times during normal operation but might be
used for diagnosing problems in some situations.

spinSilk

The command is run only when requested by Dell Technical Support.

diagClearError

The diagClearError command clears diagnostic errors detected on a specified port while running POST.
The command syntax is diagClearError <port #>; without this parameter all errors are cleared.

NOTE: When you issue this command it resets the port but does not clear the error log.

diagDisablePost

The diagDisablePost command disables POST processing. The boot time without POST processing is
approximately 25 to 30 seconds.

NOTE: Dell recommends that POST processing always be executed to ensure the operational status of the switch during the

power on stage.

diagEnablePost

The diagEnablePost command enables POST processing. The choice remains in effect across power
cycles until toggled by the user. The boot time with POST processing is approximately 60 to 65 seconds.The
factory default enables POST processing.

diagShow

Figure 7-20 shows the diagShow command, which summarizes the diagnostics results run since the switch
was last booted, including POST results. The fields are described in Table 7-11.

The command also allows you to loop on the command. For example, diagShow 4 executes diagShow
every 4 seconds continuously unless stopped by pressing <Enter>. This may be used to isolate a bad
GBIC. A port with a changing LLI_errs value is prefixed by "**" in the display. The following example shows
two passes, the first pass without an error on the line st11 (in bold) and the second pass shows an error on

Troubleshooting: Dell™ PowerVault™ 50F 8-Port Fibre Channel
Switch Installation and Troubleshooting Guide

Overview • Diagnostic overview • Status and activity indicators

Overview

This chapter discusses troubleshooting, diagnostic testing, and error messages, including the following
sections:

Diagnostic overview
Status and activity indicators

Diagnostic Overview

The switch is designed for maintenance-free operation. When there is a suspected failure, the switch has
self-diagnostic capabilities to aid in isolating any equipment or Fabric failures.

The switch supports power-on self-tests (POSTs) and diagnostic tests. The diagnostic tests determine the
switch's status and isolate problems.

Telnet commands are used to determine the switch's status, error conditions, and switch operating statistics.

Issuing Telnet Commands

Telnet commands (see "PowerVault™ 50F Commands") are available to determine the switch's status, error
conditions, and switch operating statistics.

The diagnostic procedures are completed using commands during a Telnet session.

Isolating a System Fault

Various loopback paths are built into the switch hardware for diagnostic purposes. A loopback path test
within the switch verifies the proper internal Fibre Channel port logic functions and the paths between the
interfaces and central memory.

The switch's diagnostics also support external loops, which include interface cards and their Gigabit Interface
Converter (GBIC) modules in cross-port configurations. These port-to-port diagnostics allow checking
installed fiber cables and port fault isolation.

Removing Power

After all data transferring processes external to the switch are completed, removing power from the switch
does not disrupt the Fabric.

Troubleshooting: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

At power-on or reset, the following steps are executed:

NOTE: Error messages are stored in random- access memory (RAM) and are lost when power is removed from the switch.

Access the error message log to view and note any error messages before removing power from the switch.

Status and Activity Indicators

The following status activity indicators applies to G_Port and FL_Port interface cards.

NOTE: FL_Port interface cards have an additional green light-emitting diode (LED) (visible from the front of the switch) to

identify them from G_Port interface cards.

Front-Panel LED Power Indicators

The color and flash speed of the power LED, as described in Table 8-1, indicates the switch's status.

Initialization Steps

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/TROUBLES.HTM[3/15/2013 11:32:04 AM]

Troubleshooting: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

1. Preliminary POST diagnostics.

2. VxWorks operating system initialization.

3. Hardware initialization (resets, internal addresses assigned to G_Port and FL_Port ASICs, serial port
initialized, front panel initialized).

4. Full POST.

5. Link initialization; receiver/transmitter negotiation to bring connected ports online.

6. Fabric analysis; the switch checks for ports connected to other Fabric elements. If there are other
Fabric elements connected, it identifies the master switch.

7. Address assignment; after the master switch is identified, port addresses may be assigned. Each
switch tries to keep the same addresses that were previously used. These are stored in the switch's
configuration flash PROM.

8. Routing table construction; after addresses are assigned, the unicast routing tables are constructed.

9. Enable normal N_Port operation.

Power-on Diagnostics

If a malfunction is discovered during the POST process, it is written to the system error log and is available
for analysis via a Telnet session. (See "diagShow

" and " errShow" for details.)

If the malfunction prohibits the switch from completing the boot process (fatal error), the switch stops the
boot process.

NOTE: A switch boot failure indicates the switch must be taken offline to be either repaired or replaced.

Channel Switch Installation and Troubleshooting Guide

Overview

Overview

This chapter covers the recommended and supported field repair and replacement for the switch.

NOTE: Any switch repair or part replacement that is not explained in this chapter must be performed at a factory

authorized repair facility.

The PowerVault™ 50F has no user-serviceable components except for the GBIC modules. For repair other
than the GBIC modules, the entire switch must be replaced in the event of failure.

Installing a GBIC Module

The dual channel interface card accepts two GBIC modules. These modules are installed and removed by
sliding into the interface card from the front of the unit.

NOTE: The GBIC module is installed after the interface card has been installed in the chassis. You cannot install an

interface card if it has a GBIC module installed.

To replace an IBM GBIC module into an interface card

Dell Contact Numbers

When you need to contact Dell, use the telephone numbers, codes, and electronic addresses provided in

Tables 10-1

international calls. Table 10-2 provides local telephone numbers, area codes, toll-free numbers, Web site
and e-mail addresses, if applicable, for each department or service available in various countries around the
world. If you are making a direct-dialed call to a location outside of your local telephone service area,
determine which codes to use (if any) in Table 10-1 in addition to the local numbers provided in Table 10- 2.
For example, to place an international call from Paris, France to Bracknell, England, dial the international
access code for France followed by the country code for the U.K., the city code for Bracknell, and then the
local number as shown in the following illustration.

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/GETTING.HTM[3/15/2013 11:32:06 AM]

and 10-2. Table 10-1 provides the various codes required to make long-distance and

Getting Help: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

Japan (Kawasaki) 001 81 44

To place a long-distance call within your own country, use area codes instead of international access codes,
country codes, and city codes. For example, to call Paris, France from Montpellier, France, dial the area code
plus the local number as shown in the following illustration.

The codes required depend on where you are calling from as well as the destination of your call; in addition,
each country has a different dialing protocol. If you need assistance in determining which codes to use,
contact a local or an international operator.

NOTE: Toll-free numbers are for use only within the country for which they are listed. Area codes are most often used to

call long distance within your own country (not internationally)—in other words, when your call originates in the same
country you are calling.

Switch Installation and Troubleshooting Guide

Overview • Error Message Formats • Error Messages by Firmware Module

Overview

This appendix explains the error message format, error message by firmware module, and other possible
errors.

Error Message Formats

There is one error message format for the PowerVault™ 50F whether you are gathering information from the
local RS-232 serial port or using a remote Telnet session.

In all cases, the last error encountered is the first error displayed. Up to 32 messages are held in a buffer. If
the 32 message limit is exceeded, the messages are overwritten in a first in, first out sequence.

The errShow command displays all detected errors. The output provides additional information over the
front panel display. The following information is displayed in Figure A-1

There are two errors which have been detected.
The task ID and task name that incurred the error (task name are displayed using the i command).
The error type, date and time, the error level, and description.
If there is more than one occurrence of an error type, the number of occurrences is shown in brackets
following the error level.

NOTE: The error counter goes to a maximum of 999.

The display halts after each error is displayed, prompting you to either press <Enter> to continue or type a Q
to quit. Continue pressing <Enter> until the prompt (=>) is displayed.

Error Messages: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

This module includes errors that cause a system panic to occur. A system panic causes the switch to reboot.
The PANIC error is stored in flash memory with a stack trace, local stack content and local register content at
the time the error occurred.

To view the trace, allow the switch to reboot and issue the traceShow command. If the trace was caused by
a PANIC error, the first line displays:

Reset reasons 0x100: Panic

PANIC errors have the highest severity (0).

NOTE: Use the traceShow command to identify PANIC errors as the errShow command is not useful in this case.

MQ-QWRITE Error

The software includes several message queues that are used for inter-task communication. Each queue
holds a maximum of 64 messages. Under normal operations, a task sends a message to another task on a
queue, and occupies a slot in the queue. After the message is received, its slot in the queue is open for
another message.

If the receiving task does not run for a period of time, and the sender task sends more than 64 messages to

file:///C|/Users/sharon_anand/Desktop/PowerVault/50f_enit/ERROR.HTM[3/15/2013 11:32:10 AM]

Error Messages: Dell™ PowerVault™ 50F 8-Port Fibre Channel Switch Installation and Troubleshooting Guide

the same queue before the first message is processed by the receiving task, the queue overflows and the

message is discarded. This event causes the MQ-QWRITE error to be printed on the display, as well as on
the Telnet window, if open. The error is also stored in the error log which can be viewed with the errShow
command.

NOTE: The error log is cleared upon reboot.

There may be several reasons for this error. In some cases, the system may recover without human
intervention, however in most cases it will not. In some cases, the error can even indicate a task crash.

These problems can be diagnosed by technical support provided enough information is collected to allow a
detailed analysis of the specific case.

The MQ-QWRITE error message is shown in Figure A-2 (the front panel displays an abridged version of the
message).

Figure A-2. MQ-QWRITE Error Example

The most notable parameters are:

The ID of the task that attempted to send the message (tTimers in Figure A-2)
The queue ID (0x103d1d20 in Figure A-2)
The message pointer (0x103fd3d0 in Figure A-2)

The following commands should be executed, and their output, together with the complete message log
should be used when analyzing the error.

NOTE: Some of these commands can only be run from the root account.

This chapter contains general information and examples on managing and monitoring the switch via the
PowerVault™ 50F Fibre Channel Switch Manager. The following topics are discussed:

Fabric View Page
Fabric Topology View Page
General Switch View Page
Port Detail View Page
Performance View Page
Administrative Interface Page

Fabric View Page

The Fabric View Page displays the switches in a grid. The lines between switches represent what the Fabric
knows about a switch, but do not indicate connectivity or how the switch is connected to the Fabric.

Double-click on a switch to display the General Switch View Page to provide additional switch information.
Selecting the Fabric Topology button displays a Fabric Topology View Page.

Fabric Topology View Page

The Fabric topology is viewed from the host domain (or host switch), which is initially requested from the
Web browser. This page is broken up into two figures and shows the physical configuration including active
domains, paths, and routing information (for example, the hop count which is the number of switches that
handle a data frame from origination to the destination). See Table 6-1 for field details.

The first item that appears in this page is a list of active domains (or switches) in the Fabric. Following the
active domain list is a table unfolding the views of active paths from the host domain to all remote domains in
the Fabric. This table is grouped by domains. The worldwide name and Internet Protocol (IP) address are
included under each domain. Each active path table displays host switch output port number, host switch
input port number, the hop count and metrics (costs) from the host domain to the remote domain, and the
path flag.

General Switch View Page

The General Switch View Page displays when you query the switch from the Fabric View Page (see Table
6-2 for field descriptions). A photographic quality switch is displayed on the browser. The switch picture
displays the ports, light-emitting diodes (LEDs), general switch information, temperature, fans and buttons
for administration functions, Telnet session, and performance view.

The admin button links to the system administration pages where you can disable/enable a port depending
on the appropriate authentication (see Table 6-5 and "Administrative Interface Page" in this chapter for more
information). The performance button links to the Performance View Page (see "Performance View Page
for more information). The Telnet button launches a Telnet session (see "Telnet Interface Page

").

"

Under normal conditions, the browser's lower-right corner holds animated thermometers and spinning fans.
The color and blinking speed of the port LEDs are updated every 1 to 2.5 seconds depending on the
operating system and browser used. Warning messages show up in a pop-up window automatically if
problems occur (for example, temperature exceeding maximum value, a fan stops rotating, or a port state
becomes problematic). Pushbuttons are placed in the bottom of the warning message pop-up window. Those
buttons are connected to a separate browser providing basic troubleshooting guides.

The thermometer indicates the highest temperature from the last data sample. Click on the thermometer to
display the temperature readings from all five switch sensors.

On the left side of the display, the upper half shows port and LED status and the lower half contains general
switch information. Selecting the label on each text field displays a pop-up dialog that explains the field.

In the switch picture, the blinking green lights indicate problem status and solid black indicates no device
attached. Each port module is a clickable hyperlink that takes you to a third page, the Port Detail View Page
(see Table 6-3 and "Port Detail View Page" in this chapter for more information). Each port includes the port
number, a status LED, and port detail information.

If a port card is not installed, a solid black rectangle is displayed and the port status is indicated as No_Card.
If the interface is installed but no Gigabit Interface Converter (GBIC) is present, a silver rectangle is displayed
and the port status is indicated as No_Module.

If the port contains a GBIC, one of the following is shown:

For copper GBICs, a graphic representation of a copper GBIC with the letters "CU"
For shortwave fiber GBICs, a graphic representation of a GBIC with the letters "S" and "W"
For longwave fiber GBICs, a graphic representation of a GBIC with the letters "L" and "W"
If the port is on an arbitrated loop, the letters "F/L" are displayed in an oval between the ports
associated with the card.
If the port has failed, the port is outlined in amber to indicate a failure.

The color and flash speed of each LED, as described in Table 6-3, indicates port status.

Timed_out Number of timed out interrupts.

Port Detail View Page

The Port Detail View Page features eight cascaded folders. Each folder has a tab on the top to show the
port number and a status light to tell the port state (disabled or enabled with the same light as described in
Table 6-3). The port information is updated once per second. However, the time interval may be as long as

2.5 seconds depending on the browser used. By monitoring the eight tabs, a system administrator can
evaluate each port state. The default top folder displayed on this page is for the port number checked from
the General Switch View Page. Clicking a tab brings the corresponding port folder to the front.

Below the folders is a pushbutton linked to the Administrative Interface Page (see "Administrative Interface

Page" for more information) where port enable/disable can be performed. A pushbutton is linked to the

Performance View Page (see "Performance View Page

" for more information) where port and switch

throughput data is plotted. A Done pushbutton is used to exit from the page.
Each port folder contains general port status information such as the port number, port type (E-Port, G-

Port), port WWN name, and some detailed information, such as the number of interrupts, number of link
failures, number of parity errors, number of time-outs, and the size of free buffer.

The LED located in the upper-right corner in each tab resembles the port LED in the switch front panel.

Performance View Page

The Performance View Page displays port and switch throughput (in bytes per second). The first eight
graphs show the port throughput for port number 0 through 7. Throughput for the entire switch is displayed in
the long rectangular graph at the bottom.

The horizontal axis represents time elapsed. The port throughput graphs hold up to 60 seconds of
performance data. The switch throughput graph at the bottom holds up to 4 minutes of performance data.
The vertical axis in each graph shows throughput (in bytes per second). It is automatically scaled depending
on the switch activity. The display is updated roughly once per second.

The total throughput value is the throughput sum for all ports. The throughput number represents the number
of bytes received plus the number of bytes transmitted each second. Note that, because the switch also
transmits all data it receives, the total throughput for the switch could, alternately, be stated as one-half (1/2)
of the throughput sum of all ports.

Administrative Interface Page

Only users with admin privilege can access the Administrative Interface Page. Any changes made through
this may fundamentally change the switch/port status and its role in the fabric. Check and input boxes are
provided for you to type in the changes. Submit buttons are used to apply the changes. You can enable (or
disable) the switch or ports (8). Change switch name, IP addresses, user name, passwords, download flash,
and reboot switch via this page. Table 6-5 provides field information for the Administrative Interface Page.
