Introduction
Option Kits
The StorageWorks Fibre Channel Storage Switch is a key component of the Enterprise Network Storage Area (ENSA) implementation. The Switch is used to connect network servers with storage devices, such as Compaq’s RA8000/ESA12000 HSG80 RAID Array Storage Subsystems, to create a Storage Are a Netwo r k (SAN). There are two Switch Option Kits (Mo del s), an 8-port model and a 16-port model. The 8-port model contains four dual-port interface cards; the 16-port model has eight interfaced card installed on the motherboard.
NOTE:
Note: Zoning, Cascading, FL_ports, SES, and Copper Media are not fully supported by Compaq as of April 1999. However, the software bundle that enables these features is included in the software package with this Switch and is provided at no additional cost so that customers may have the opportunity to become familiar with these advanced SAN functions. Compaq will support many of these and other SAN functions in the future. Contact your Compaq Authorized Reseller or Compaq Account Representative for specific information on these features.

Selecting an Operating Location
The Switch should be located in a secure or limited-access place to control use of the Switch front panel controls, and to ensure that cable connections are not compromised. The operating location you select for the Switch must meet cooling air requirements and power requirements.
Cooling Air Requirements
Cooling air is drawn into the Switch chassis by the power supply fan and by two other fans mounted on the rear of the chassis; the air is expelled through vents in the front of the chassis. The combined air flow through the Switch is 75 cubic feet per minute (cfpm), and nominal bulk flow of 15 cfpm.
CAUTION:
Do not block the front or rear air vents . The Switch must have free
access to ambient air for cooling.
Page 24
2-4 StorageWorks Fibre Channel Storage Switch User's Guide
Power Requirements
You connect the ac power cord to a switched connector on the bottom right side of the Switch front panel. The ac power source must meet thes e requirements:
A properly–wired, earth–grounded ac outlet
Voltage capability of 90–134 Vac or 180–257 Vac, and IEC 801-5 surge voltage
Input voltage frequency of 50–60 Hz
Power capability of 219 watts, maximum.
The Switch has an autoranging power supply that automatically accepts voltages within its range. There is no provision for surge protection built into the Switch power supply so the ac source should include provisions to assure clean ac power.
Selecting a Switch Mou ntin g Metho d
The Switch can be placed on a table top or other surface, or it can be mounted in an equip ment rack.
Placing the Switch on a Surface (Table-top Mounting)
You can set the Switch on a surface, such as a table top, and operate it from that location. Although adhesive rubber feet are included in the Installation Kit, they are not necessary for proper or safe operation of the Switch. If you want to install the rubber feet, perform these steps:
Use the alcohol wipes to clean the depression in each corner of the bottom of the chass is ; allow th e alcohol to dry.
Remove the rubber feet from the sheet and insert one in each depression.
Press the rubber feet in place firmly.
Page 25
Installing the Switch 2-5
For table-top mounting continue the installation procedure with Installing the GBIC Modules.
NOTE: If you attach rubber feet, you have to remov e them before you can install the Switch in a 19- inc h eq ui pm e nt rac k.
Mounting the Switch in an Equipment Rack
You can install the Switch in a RETMA 41U or 42U rack, in a Compaq rack, or in a metric SW600 rack. Observe the following guidelines:
When you install the Switch in a closed or multi–rack assembly, be sure the air temperature measured at the Switch front panel does not exceed 40° C (104° F).
Make sure the air flow to the Switch is at least 300 cfpm.
Verify that when the Switch is installed it does not unbalance the rack or exceed the rack mechanical limits, both with the slide brackets secured and with the slide brackets fully extended.
Verify that the supply circuit, the line fuse, and the wire size are appropriate for the service.
Verify that all the other equipment installed in the rack has a reliable ground connection; do not rely on connection to a branch circuit, such as a power strip.
Route and support the power cord to ensure that the Switch moves freely on the slide brackets without crimping or chafing the power cord, or interfering with other equipment and cables installed in the rack.
Before you install the Switch in the rack you must attach mounting brackets to the rack rails. Where you attach the mounting brackets vertically in the rack depends on your installation, i.e., what other equipment is mounted in the rack along with the Switch. The only tool you need is a Number 2 Phillips screwdriver. Perform the applicable procedure from the following subsections.
Attaching Mounting Brackets in a RETMA 41U Rac k
You mount the Switch in this rack from the front of the rack only. Perform the following steps:
1.
Position the mounting template against the front and rear vertical rails (Figure 2–2), first on one side of the cabinet and then on the other side; make sure the template is parallel from front–to–rear.
Page 26

Installing GBIC Modules
Each interface card installed in the Switch has two G_Ports. A GBIC module must be installed in each G_Port in order to use that port. Perform the following steps to install a GBIC module.
CAUTION:
The GBIC modules contain static sensitive com ponents. Use ES D precautions when handling this card.
CAUTION:
When you insert the GBIC module in the next step, do not force the module if you feel resistance.
1. Insert the GBIC module into the G_Port. The module is keyed and you
can insert it only one way; if you feel resistance after you have inserted the module about an inch into the G_Port, you have oriented it incorrectly. When it is oriented correctly, be sure the locking bar on the front of the module is positioned to the right.
2. W hen the GBIC module is fully inserted lock it in place by moving the
locking bar to the left.
3. Insert a rubber protective plug over the module fiber–optic connectors.
4. Re peat the procedure for each GBIC module to be installed.
Connecting Cables to the Switch
All cables connect at the front of the Switch. Install two push–mount cable ties so you can route the power and data cables along the rack rails (Figure 2-11).

Fabric Management through a Single Ethernet Port
Multiple Compaq Storage Switches can be managed through a single IP connecti o n to one of the Switc hes u sing Telnet se r vice s, We b Tools o r SNMP commands, shown in Figure 3-2. Each Switch supports a 10bT Ethernet connection that has generally been the link for IP services. There is a second IP connection, the Fibre Channel IP or in-band support which is also available for use when managing a Switch.
Ethernet
Switch 1
Switch 2
Switch 3
FC IP

Management Station
Figure 3-2. Single-port Management of Switches
At this point there are no Host Bus Adapters (HBAs) that can initiate in-band fibre channel IP connections. For that reason, it is necessary to have at least one Ethernet connection into the Fabric. From that one entry point, it is possible to manage the remaining Switches in the Fabric using in-band IP services.
The management workstation, which runs a browser, a Telnet session or SNMP, will need to be able to add ress t he Switc h that has an Ethern et connection. This means that the management workstation and the Ethernet IP address of the a Switch need to be in the same subnet. In addition, the manage ment station must either hav e a s tatic route to the FC IP su bnet, or the Switch must be the default gateway for the management workstation. This will allow the management station to direct IP to or through the Switch.
Page 41
Managing the Switch 3-5
The Switches not connected to the Ethernet must have their default gateways set to the Fibre Channel IP address of the Switch connected to the Ethernet. Also, these Switches must have their FC IP addresses in a different subnet from the Ethernet IP addresses of the management station. Lastly, the FC IP addresses of all Switches must be in the same subnet. Example settings follow:
Management Station
Switch 1Switch 2Switch 3
Ethernet IP Address
192.168.1.09 192.168.1.10 204.1.1.11 204.1.1.12
FC IP Address 192.168.65.09 192.168.65.10 192.168.65.11 192.168.65.12 Default
Gateway
192.168.65.10 (any) 192.168.65.10 192.168.65.10
The effect of this special connectivity is that the route to all switches will be through the single Switch with the Ethernet connection. The route back to the workstation from the other Switches will also be though that initial Switch. The initial Switch, which has both Ethernet and FC IP capability, will act as a “bridge” in that it will route between Ethernet and FC IP to send the traffic to the right place with the right protocol.

Domain
Pressing <Enter >, while Domain is se lected, displays:
Domain
1
The domain number uniquely identifies the Switch in a Fabric. This Switch ID is normally automatically assigned by the Switch and may be any value between 0 and 31. You may also assign the initial domain number manually.
The Switch with the lowest initial domain will become the master Switch and control the configuration.
BB_credit
Pressing <Enter >, while BB_credit is se lected, displays:
BB_credit
16
The number represents the number of buffers, from 1 to 16, available to the host. The default for G_Port cards is 16. The BB_credit for FL_Port cards is 0. For a complete description of buffer-to-buffer credit, refer to the industry specification Fibre Channel Physical and Signalling Interface (FC-PH).
R_A_TOV
Pressing <Enter >, while R_A_TOV is selected , displays:
R_A_TOV 10000
Resource Allocation Time Out Value (R_A_TOV) is adjustable in 1-second increments using front panel controls, but its value is displayed in milliseconds. This variable works with the variable E_D_TOV to determine the Switch’s actions when presented with an error condition. Allocated circuit resources with detected errors are not released until the time value has expired. If the condition is resolved prior to the timing out, the internal time out clock resets and waits for the next error condition. The range is 1 to 120 seconds.
NOTE: The set value must be larger than the set value for the Error Detect Time Out Value
Page 50
3-14 StorageWorks Fibre Channel Storage Switch User's Guide
E_D_TOV
Pressing <Enter >, while E_D_TOV is se lected, displays:
E_D_TOV
2000
E_D_TOV (Error Detect Time Out Value) is adjustable in 1-second increments using the front panel controls, but its value is displayed in milliseconds.
NOTE: Use the flashSet command during a Telnet session to set the E_D_TOV or R_A_TOV value (in milliseconds) for values other than whole seconds.
This timer is used to flag a potential error condition when an expected response is not received (an acknowledgment or reply in response to packet receipt, for example) within the set time limit. If the time for an expected response exceeds the set value, then an error condition is met. The range is 1 to 60 seconds.
NOTE: The set value must be less than the set value for the Resource Allocation Time Out Value.
Operating Mode
Pressing <Enter >, while Operating Mode is se lected, displays:
Operating Mode:
0
Page 51
Managing the Switch 3-15
The operating modes are determined by the host adapter. The five operating modes for the Switch are described in Table 3-4.
Table 3-4
Operating Mode Definitions
Mode Description
0 Normal operating mode, none of the following modes are in effect
1
Tachyon operating mode. Set this mode when there is one or more Tachyon host adapters connected to the Fabric, and a protocol other than SCSI-FCP is being used over this host adapter. When this mode is set, multiple Sequences from different sources will be interleaved to Tachyon at Sequence boundaries rather than at frame boundaries, resulting in better performance from Tachyon.
2 Isolated operating mode. Set this mode only if the switch’s E_Port discovery process
(transmission of a Class F frame) causes some attached device to fail. When this mode is set, switches will not join to become a Fabric.
4 No_Probe operating mode. Set this mode only if the switch’s N_Port discovery process
(PLOGI, PRLI, INQUIRY) causes some attached device to fail. When this mode is set, devices that do not register themselves with the Name Server will not be present in the Name Server data base.
8
No_MCast operating mode. Set this mode only if buffer-to-buffer credit values greater than 16 are needed, and broadcast and multicast are not needed. When this mode is set, the normal range of buffer-to-buffer credit is changed from 1-16 to 1-62 and broadcast and multicast are disabled.
NOTE: These modes are additive, for example to set a Switch in Tachyon mode and in No_MCast mode, the operating mode should be set to 9. Any combination of bit maps can be set up to 16, all values above 16 are ignored.
Virtual Channels
The Switch provides the ability to tune the Switch in a specific application. The first two virtual channels are reserved for the Switch’s internal functions
and are no t availab le.
NOTE: The default virtual channel settings are already optimized for Switch performance. Changing the default values, if properly selected, may improve Switch performance somewhat, but may also severely degrade performance. You should not change these settings without fully understanding the change’s effects.

is selected, displays :
VC Priorities
0.1.2.2.2.2.3.3
The numbers displayed show the priorities assigned to each of the Switch’s virtual channels. Positions 1 and 2, starting at the left of the display, are fixed and displays 0 or 1.
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 by the user.
The second position, indicated with a 1, shows the priority assigned by the virtua l chan nel link co ntrol as described in the VC Link Ctl on page 4-22.
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.
Alternate BB_credit
Pressing <Enter >, while Alternate BB_credit is selected, displays:
Alternate BB_credit
0
The number is used in an ACC to an NL_Port's FLOGI. If this number is 0, an NL_Port must wait for an R_RDY before it can send a frame to the FL_Port in a loop. If this number is 1, an NL_Port can immediately send a frame to the FL_Port without waiting for an R_RDY. Thus reducing the loop turn around

Managing with SNMP
The resident SNMP agent allows r em ote Switc h mana geme n t via IP over Ethernet and Fibre Channel interf aces and provi des access to most of the functions described in the front panel Menu section.
This section provides an overview of key concepts about Switch management based on Simple Networ k Manageme nt Proto c ol (SNMP). Additionally, refer to other references and text books on SNMP for more detailed discussion s of the protocol and usage.
Within the SNMP model, a manageable network consists of one or more manager systems (or network management stations), and a collection of agent systems (or network elements):
A manager system runs a management application (such as StorageWorks Command Console GUI) that monitors and controls the network elements
An agent system is a network device such as a Fibre Channel Switch, a managed hub, or a bridge, that has an agent responsible for carrying out operations requested by the manager. Therefore, an agent is the interface to a managed device.
The manager communicates with an agent using the Simple Network Management Protocol (SNMP). The Switch agent supports both SNMP version 1 (SNMPv1) and Community-based SNMP version 2 (SNMPv2C).
A manager can retrieve management information, such as its identification, from an agent. There are three operations for this activity:
SNMP-GET
SNMP-NEXT
Page 66
3-30 StorageWorks Fibre Channel Storage Switch User's Guide
SNMP-BULKGET (SNMPv2C).
A manager can change management information on the agent. This operation is termed SNMP-SET.
An agent can send information to the manager without being explicitly polled for. This operation is termed a trap in SNMPv1 or a notification in SNMPv2C. Traps or notifications would alert the manager to events that occur on the agent system, such as reboot. For the rest of the document, the term trap is used.
The information on an agent is known as the Management Information Base (MIB). It is an abstraction of configuration and status information. A specific type or class of management information is known as a MIB object or variable. For example, the MIB variable, sysDescr, defines the description
of an agent system. The existence of a particular value for a MIB object in the agent system is known as a MIB object instance, or simply instance. Some MIB objects have only a single instance for a given agent system. For example, the system description and the instance is denoted as sysDescr.0.
Other MIB objects have multiple instances. For example, the operational status of each Fibre Channel port on a Switch and a particular instance may be denoted as swFCPortOperStatus.5".
MIB objects are conceptually org anized in a hierarchical tre e s tr ucture. Each branch in the tree has a unique name and numeric identifier (Figure 3-4). Intermediate branches of the tree serve as a way to group related MIB objects together. The leaves of the tree represent the actual MIB objects. Figure 3-4 illustrates the tree structure, with special attention to the Internet MIB tree and the Fibre Channel MIB tree.

Figure 3-5. MIB Tree
A MIB object is therefore uniquely identified or named by its position in the tree. A full object identifier consists of the identifier of each branch along the path through the tree. For example, the object sysObjectID has the full
identifier of 1.3.6.1.2.1.1.2. For readability the notation {system 1} may be used.
The Switch’s agent supports the following:
SNMPv1 manager
Command line utilities to provide access to and command the agent.
MIB-II system group, interface group, and SNMP group
Fabric Element MIB
Vendor-Specific MIBs
Standard Generic traps
Enterprise Specific traps.
SNMPv1 Transports
The SNMP agent residing on the embedded processor supports UDP/IP over the Ethernet interface or any FC-IP interface. This transport provides an immediate “plug-and-play” support for the Switch, once the IP address has been assigned.
Page 68
3-32 StorageWorks Fibre Channel Storage Switch User's Guide
MIB-II Support
There are eleve n groups o f objects specified in MIB-II. The Switch’s SNMP agent supports 3 of these groups. The three groups supported include:
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, give n an appropriate community with read-write access:
The Switch is shipped with the default identifiers.
SysDescr System des cription: the default value is set as “Fi br e Cha nne l 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 agent 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.
Fabric Element MIB Support
There are five object groups defined:
Configuration group
Operation group
Error group
Accounting group
Capability group.
The agent supports all groups.

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 agent has reinitialized itself such that the agent’s co nfigur ation can be altered.
warmStart – indicates the agent 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) h as b ecome av ailable.
NOTE: linkUp and linkDown traps are not associated with removing or adding a Ethernet cable. This is strictly a driver indication that the interface is configured, operational, and available and does not necessarily mean that the physical network cable is connected.
authenticationFailure – indicates the agent 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. They are:
swFault – indicates the diagnostics detect a fault with the Switch.
swSensorScn – indicates 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.
Page 70
3-34 StorageWorks Fibre Channel Storage Switch User's Guide
swFCPortScn - a notifica tio n that a Fib re Channel Port changes its operational state. For instance, the Fibre Channel Port goes from on-line to offli ne. The Var B ind in the Tr ap 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.
Agent Configuration
NOTE: 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 parameters that can be configured include:
SNMPv1 communities (up to 6)
trap recipients (1 per community)
sysName
sysContact
sysLocation
authenticationFailure – indicates the agent 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 paramet ers can be conf igured via a Telnet
connection, us ing the command agtcfgSet.
NOTE: A change in the first two configuration parameters takes effect only after rebooting the Switch.

syslog Daemon
A UNIX style syslog daemon (syslogd) process has been added. Syslogd reads system events and forwards system messages to users and/or writes the events to log files according to your system configuration.
Introduction
Syslogd reads system events and forwards system messages to users and/or stores them in log files according to your system configuration. Events are categorized by facility and severity. Please refer to the manual pages on your UNIX system for a list of facilities and severity levels. The log process is used to log errors and system events on the local machine and are sent to a user or system administrator. The daemon is constantly running and ready to receive messages from system processes . The events are logged ac cording to the statements in the configuration file. In addition, syslogd is enab led to receive messages from a remote machine. Syslogd listens to UDP port 514 for system events. A remote machine does not have to be running UNIX to forward messages to syslogd. But it must follow the basic syslog message format standard.
Page 75
Managing the Switch 3-39
An examp le entry in a syslogd log file is:
Jul 18 12:48:00 sendmail[9558]: NOQUEUE: SYSERR(uucp): /etc/mail/sendmail.cf: line 0: cannot open: No such file or directory
The first two items are the event’s date/time (as known by the machine where syslogd is running) and the machine name that issued the error. This would be the local machine, if the message is generated by a task runn ing on the same machin e as s yslogd, or a remot e machine, if the mes s age was received on UDP port 514. The first two items are always present , all other entries are mess age specific.
NOTE: The log file may be located on a different machine and be remotely mounted. So a local error is an error that occurred where syslogd is running, not on the machine where the error log physically resides.
syslogd applications for NT and Win95 are available at no charge on several FTP servers on the Internet
syslogd Support
Switch firmware maintains an internal log of all error messages. The log is implemented as a circular buffer, with a storage capability of 30 errors. After 30 errors have been logged, the next error message overwrites the messages at the beginning of the buffer.
If configured, the Switch sends internal error messages to syslogd by sending UDP packet to port 514 on the syslogd machine. This allows the storage of Switch errors on a syslogd capable machine and avoids the limitations of the circular buffer.
syslogd provides system error support via a single log file and can notify a system administrator in real time of error events. Additionally, the daemon provides dial home capability.
Page 76
3-40 StorageWorks Fibre Channel Storage Switch User's Guide
Error Message Format
Each error message logged sends the following information:
Error number (1 for the first error after boot, increments by one with each new error).
The error message, exactly as it is stored in the error log (and printed via the command errShow).
The error number makes it easy to identify the error and also determine when a Switch rebooted. If there is a log of error number N from the Switch, followed by another log of error number 0 from the Switch, then the Switch rebooted
between the two errors. The error message includes the Switch that reported the error with the
following event information:
ID of the task that generated the error.
Name of the task that generated the error.
Date and time when the error occurred, as seen by the Switch. This may be different from the first item in the log file, which is the time as seen by the syslogd machi n e. These tw o time valu es ar e differ ent if the clocks in the Switch and in th e syslogd machine are not in sync.
The error identifier consisting of a module name, a dash and an error name.
The error severity.
Optional informational part.
Optional stack trace.

Managing the Switch 3-41
Example: syslogd running on Switch sw9 is sending log events to the UNIX machine
called example. The following is an example of a No memory error generated by the shell. This is a severity 1 (LOG_CRITICAL) error. syslogd is configured to store the errors in: /var/adm/silkworm file.

Message Classification
syslogd messages are classified according to facility and priority (severity code). Thus allowing a system administrator to take different actions depending on the error. The action taken, based on the message’s facility and priority, is defined in the syslog configuration file. Example configurations are provided in a following section.
The Switch uses the facility local7 for all error messages sent to the syslogd.
UNIX provides eight priorities, whereas the Switch provides four severity codes (code LOG_PANIC (0) causes a reboot and is not sent to the syslogd).
The mapping between the Switch’s severity codes and UNIX syslogd priori ti es is provided in Table 3-9.
Table 3-9
syslog Message Classification
Switch UNIX
LOG_CRITICAL (1) alert
LOG_ERROR (2) err
LOG_WARNING (3) warning
LOG_DEBUG (4) debug
Page 78
3-42 StorageWorks Fibre Channel Storage Switch User's Guide
Switch configuration
To start the syslogd type the following command:
syslog dI p <IP address of the sys logd machine>
The command with no parameter prints the IP address of the current target syslogd machine. An IP address of
0.0.0.0
disables the forwarding of error messages to syslogd. In this case, error messages are still logged int ern ally to the Switch, but it is not forwarded to the syslogd.
Examples, Enable and verify syslogd support:
=> syslogdIp “10.0.0. 1” => syslogdIp
syslog daemon’s address: 10.0.0.1
Disable syslogd support:
=> syslogdIp “0.0.0.0 ” => syslogdIp
syslog daemon’s address: 0.0.0.0
syslogd configuration
The syslog configuration provides th e syslogd with instru ct ions on how to handle different messages. The following are example entries in a syslog configuration file (
/ etc/syslog.conf
), on how to store Switch error
messages stored in different files. Please refer to the syslog manual pages on your UNIX system for the full documentation of the syslog configuration file. The following entry in
/etc/syslog.conf
causes all messages from t he
Switch
of UNIX priority warning or higher (Switch severity
LOG_WARNING
or higher) to be stored in the file
/var/adm/silkworm
.
local7.warning /var/adm/silkworm
The following entries in
/etc/syslog.conf
causes the messages from the
silkworm
of UNIX priority alert (Switch severity
LOG_CRITICAL
) to be
stored in the file
/var/adm/alert
, and all other messages from the Switch
to be stored in the file
/var/adm/silkworm
.
local7.alert /var/adm/alert local7.debug /var/adm/silkworm
Page 79
Managing the Switch 3-43
The local7 prefix identifies the message from a Switch. Note that usually a file must exist and have the proper permission in order for the syslogd to write to it.

Fabric View Page
The Fabric View Page shows the number of network Switches and confirms worldwide names, domain IDs, and Switch names.
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 informa tion, 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 LED status. From this view, more information is available about the Switch by moving to either the Performance View or the Port Detail View.
Performance View Page
The Performance View Page shows graphically real-time data throughput for each port and Switch bandwidth utilization.
Two types of performance data: 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
Page 88
5-4 StorageWorks Fibre Channel Storage Switch User's Guide
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 Interface Page
The Administrative Interface Page is used to perform routine functions such as enabling and disabling ports. Upgrading firmware can also be initiated from this pag e.
Telnet Interface Page
The Telnet Interface Page uses Telnet commands (configuration, diagnostics, displaying, and routing) for Switch diagnostics, troubleshooting, and management.
Installing Web Tools and Logging on to the Switch
Fabric Management and Licensing
All Compaq Switches are l ic ense. It is po ssibl e that oth er Swit c hes in a Fabric may not have the Web browser license key installed. This does not prevent a Switch from appearing in the Fabric view page on the browser, but attempting to click on an unlicensed Switch in order to manage that Switch results in a failure. Each Switch must contain a web management license in order for the web browser to display detailed performance data on ports, enter administrative data, and to perform Switch management functions on that Switch using the web. Telnet and SNMP can always be used to manage a Switch wi th o ut a license.
Page 89
Managing the Switch over the Web 5-5
License Installation
Web management requires a license to operate. Without a License key installed in the Switch, Web browsers are not able to connect to the Switch. The License Key has been installed at the factory for Compaq Switches.
CAUTION:
If an invalid key number is entered the existing license (if any) is overwritten, thus eliminating any/all valid license keys. The license key is unique to each Switch; therefore, a license for one Switch will not operate on another.
To install the License Key:
1. Log on the Switch via Telnet.
2. On the Telnet comm an d line, type:
licenseShow
3. Verify the current license keys, if the Web key is not installed continue
with the next step.
4. On the Telnet comm an d line, type:
licenseAdd “key”
where, “key” is the license key string of alphanumeric characters in double quotes (“key”) that must be entered exactly as given including case. For example, “RdxS9S9ezSd cdTs”.
5. Once the license is entered, check for it with the licenseShow command
and if present reboot the Switch.

To access the administration scree n s , click on the Admin butt o n then enter your username and password at the prompt.
NOTE: 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.
Web Tools Operational Concepts
When using Switch Web Tools note the following: Clickable areas are highlighted with a hint displayed in the left side bottom bar
of your browser when the mouse is positioned over them (Switches on the Fabric View page, ports and thermo meter on the Gener al Switch View page; the Admin/ Telnet/performance buttons are not highlighted, however, glossaries in the Switch general Information area are not highlighted).
When making changes in the Admin page, the Response Page shows whether each individual configuration change was committed or rejected.
Java is disabled in some versions of Netscape and must be enabled by checking both Enable Java and Enable Java Script buttons in the
Preferences/Advanced
menu.
Netscape or IE may hang with Java applications on Windows NT after SP3 due to True Color. To work around this problem, either change the NT display settings to other than True Color, or download Microsoft’s hotfix to modify WIN32K.SYS. The hotfix is available from Microsoft Technical Support.

On the left side of the display, the upper half shows port and LEDs status and the lower half contains general Switch information. Table 5-2 describes the fields. Selecting the label on each text field displays a popup dialog that explains the field.
In the Switch picture, LEDs indicate problems or status. Refer to Table 5-3 for LED definitions. Each port module is a clickable hyperlynk which takes you to a third page, the Port Detail View page. 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 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 short wave fiber GBICs, a graphic representation of a GBIC with the letters “S” and “W”
For long wave fiber GBICs, a graphic representation of a GBIC with the letters “L” an d “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 5-3 , indicates port status.

Port LED Status Indicators
Port LEDs Definition
No light showing
No light (no module, no cable) for media interface LEDs, power not applied for power indicator LED
Steady yellow Receiving light, but not yet online. If the port transitions to this state
while being monitored, the applet presents you with a dialog recommending a course of action.
Slow yellow
Disabled (result of diagnostics or portDisable command). Flashes every 2 seconds. The applet presents you with a dialog recommending a course of action.
Fast yellow
Error, fault with port. Flashes every 1/2 second. The applet presents you with a dialog recommending a course of action.
Steady green Online (connected with device over cable)
Slow green
Online, but segmented (loopback cable or incompatible Switch) flash every 2 seconds.
Fast green Internal loopback (diagnostic). Flashes every 1/2 second.
Flickering green Online and frames flowing through port.

Port Detail View Page
The Port Detail View Page, Figure 5-6, provides statistics for each port. The page features 16 cascaded folders (tabs) 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.
The port information is updated once per second. However, the time interval maybe as long as 2.5 seconds depending on the browser used. By glancing at those 16 or 8 tabs, a system administrator will gain the knowledge of each port state. The default top folder displayed on this page is for the port number checked from the General Switch View Page. Clicking on a tab brings the corresponding port folder to the front.
NOTE:
This page shows an FL_Port as being offline if you are running cross port connected testing, the reason is that you can have only one Principle per Switch. The FL_Port to FL_Port testing still proceeds even though this is NOT the correct way to connect FL_Ports.
Below the folders is a push button linked to the Administrative Interface Page where port enable/ disable can be performed. A push button linked to the Performance View Page where port and Switch throughput data is plotted. A Done push button 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's 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.
Port Detail View Page field are described in Table 5-4.
