Switch Management

This chapter explains the methods that you can use to configure management access to
the switch. It describes the types of management applications and the communication
and management protocols that deliver data between your management device
(workstation or personal computer) and the system. It also contains information about
port connection options.

Console (CLI)

The administration console is an internal, character-oriented, Command Line Interface
(CLI) for performing system administration such as displaying statistics or changing option
settings. Using this method, you can view the administration console from a terminal,

port. There are two ways to use this management method: direct access or modem access.
The following sections describe these methods.

Direct Access

Direct access to the administration console is achieved by directly connecting a terminal
or a PC equipped with a terminal-emulation program (such as HyperTerminal) to the
switch console port. This management method is often preferred because you can remain
connected and monitor the system during system reboots. Also, certain error messages
are sent to the serial port, regardless of the interface through which the associated action
was initiated. A Macintosh or PC attachment can use any terminal-emulation program for
connecting to the terminal serial port. A workstation attachment under UNIX can use an
emulator such as TIP.

Modem Access

external modem attached to the console port. The switch management program provides
Console Port screen, accessible from the Basic Management screen that lets you configure
parameters for modem access. When you have configured the external modem from the
administration console, the switch transmits characters that you have entered as output
on the modem port. The switch echoes characters that it receives as input on the modem
port to the current administration console session. The console appears to be directly
connected to the external modem.

IES-0880 User Manual Page 18

Web Management

The switch provides a browser interface that lets you configure and manage the switch
interface applications directly in your web browser by entering the IP address of the

switch. You can then use your web browser to list and manage switch configuration
console port.

SNMP-Based Network Management

You can use an external SNMP-based application to configure and manage the switch. This
management method requires the SNMP agent on the switch and the SNMP Network
Management Station to use the same community string. This management method, in
fact, uses two community strings: the get community string and the set community string.
If the SNMP Network management station only knows the set community string, it can
read and write to the MIBs. However, if it only knows the get community string, it can only
read MIBs. The default get and set community strings for the switch are public.

Management Architecture

All of the management application modules use the same Messaging Application
Programming Interface (MAPI). By unifying management methods with a single MAPI,
configuration parameters set using one method (e.g. console port) are immediately
displayed the other management methods (e.g. SNMP agent of web browser).

The management architecture of the switch adheres to the IEEE open standard. This
compliance assures customers that the switch is compatible with, and will interoperate
with other solutions that adhere to the same open standard.

IES-0880 User Manual Page 19

SNMP & RMON Management

Remote Monitoring (RMON) capabilities.

Overview

RMON is an abbreviation for the Remote Monitoring MIB (Management Information Base).
RMON is a system defined by the Internet Engineering Task Force (IETF) document RFC
2819, which defines how networks can be monitored remotely.

RMONs typically consist of two components: an RMON probe and a management
workstation:

- The RMON probe is an intelligent device or software agent that continually collects
statistics about a LAN segment or VLAN. The RMON probe transfers the collected data to a
management workstation on request or when a pre-defined threshold is reached.

- The management workstation collects the statistics that the RMON probe gathers.
The workstation can reside on the same network as the probe, or it can have an in­band or out-of-band connection to the probe.

The switch provides RMON capabilities that allow network administrators to set
parameters and view statistical counters defined in MIB-II, Bridge MIB, and RMON MIB.
RMON activities are performed at a Network Management Station running an SNMP
network management application with graphical user interface.

SNMP Agent and MIB-2 (RFC 1213)

The SNMP Agent running on the switch manager CPU is responsible for:

- Retrieving MIB counters from various layers of software modules according to the
SNMP GET/GET NEXT frame messages.

- Setting MIB variables according to the SNMP SET frame message.

- Generating an SNMP TRAP frame message to the Network Management Station if
the threshold of a certain MIB counter is reached or if other trap conditions (such as
the following) are met:

IES-0880 User Manual Page 20

AUTHENTICATION FAILURE
RISING ALARM
FALLING ALARM
TOPOLOGY ALARM

MIB-II defines a set of manageable objects in various layers of the TCP/IP protocol suites.
MIB-II covers all manageable objects from layer 1 to layer 4, and, as a result, is the major
SNMP MIB supported by all vendors in the networking industry. The switch supports a
complete implementation of SNMP Agent and MIB-II.

RMON MIB (RFC 2819) and Bridge MIB (RFC 1493)

The switch provides hardware-based RMON counters in the switch chipset. The switch
manager CPU polls these counters periodically to collect the statistics in a format that
complies with the RMON MIB definition.

RMON Groups Supported

The switch supports the following RMON MIB groups defined in RFC 2819:

- RMON Statistics Group maintains utilization and error statistics for the switch port
being monitored.

- RMON History Group gathers and stores periodic statistical samples from the previous
Statistics Group.

- RMON Alarm Group allows a network administrator to define alarm thresholds for any
MIB variable. An alarm can be associated with Low Threshold, High Threshold, or both. A
trigger can trigger an alarm when the value of a specific MIB variable exceeds a threshold,
falls below a threshold, or exceeds or falls below a threshold.

- RMON Event Group allows a network administrator to define actions based on alarms.
SNMP Traps are generated when RMON Alarms are triggered. The action taken in the
Network Management Station depends on the specific network management application.

IES-0880 User Manual Page 21

Bridge Groups Supported

The switch supports the following four groups of Bridge MIB (RFC 1493):

- The dot1dBase Group a mandatory group that contains the objects applicable to all
types of bridges.

- The dot1dStp Group
Spanning Tree Protocol. If a node does not implement the Spanning Tree Protocol, this
group will not be implemented. This group is applicable to any transparent only, source
route, or SRT bridge that implements the Spanning Tree Protocol.

- The dot1dTp Group
status. This group is applicable to transparent operation only and SRT bridges.

- The dot1dStatic Group -address
filtering status. This group is applicable to any type of bridge which performs destination­address filtering.

IES-0880 User Manual Page 22

switch. This interface allows you to access the switch using a preferred web browser.

This chapter describes how to configure the switch using its web-based browser interface.

forward only one IGMP report per multicast router query to multicast devices. When IGMP router
suppression is enabled, the switch sends the first IGMP report from all hosts for a group to all the
multicast routers. The switch does not send the remaining IGMP reports for the group to the multicast
routers. This feature prevents duplicate reports from being sent to the multicast devices.

Console Management

The switch provides a command line console interface for configuration purposes. The
switch can be configured either locally through its RS-232 port or remotely via a Telnet
session. For the later, you must specify an IP address for the switch first.

This chapter describes how to configure the switch using its console by Commend Line.

Administration Console

Connect the DB9 straight cable to the RS-232 serial port of the device to the RS-232 serial
port of the terminal or computer running the terminal emulation application.

Direct access to the administration console is achieved by directly connecting a terminal
or a PC equipped with a terminal-emulation program (such as HyperTerminal) to the
switch console port.

When using the management method, configure the terminal-emulation program to use
the following parameters (you can change these settings after login):

[Default parameters]
115,200bps
8 data bits
No parity
1 stop bit

MSTP Properties

Region Name:

1. Command Mode: MST Configuration mode
Logon to Configure Mode (Configure Terminal Mode).
Then logon to MST Configuration mode.
The switch_a(config-mst)# prompt will show on the screen.

switch_a(config)#spanning-tree mst configuration
switch_a(config-mst)#

2. Usage:
Use this command to create an MST region and specify a name to it. MST bridges of a
region form different spanning trees for different VLANs. By default, each MST bridge
starts with the region name as its bridge address. This means each MST bridge is a region
by itself, unless specifically added to one.

3. Command Syntax:
bridge GROUP region REGION_NAME
no bridge GROUP region

GROUP <1-1> Specify the bridge-group ID.

REGION_NAME Specify the name of the region.

4. Example:
The following example creates an MST region and specifies a name (regionname) to it in
bridge GROUP (1):

Switch_a(config)#spanning-tree mst configuration
switch_a(config-mst)#bridge 1 region regionname
switch_a(config-mst)#

Revision Level:

1. Command Mode: MST Configuration mode
Logon to Configure Mode (Configure Terminal Mode).
Then logon to MST Configuration mode.
The switch_a(config-mst)# prompt will show on the screen.

switch_a(config)#spanning-tree mst configuration
switch_a(config-mst)#

2. Usage:
Use this command to specify the number for configuration information. The default value
of revision number is 0.

IES-0880 User Manual Page 98

3. Command Syntax:
bridge GROUP revision REVISION_NUM

GROUP <1-1> Specify the bridge-group ID.

REVISION_NUM <0-255> Revision number.

4. Example:
The following example specifies a revision number (25) of MST configuration in bridge
GROUP (1):

switch_a(config)#spanning-tree mst configuration
switch_a(config-mst)#bridge 1 revision 25
switch_a(config-mst)#

Max Hops:

1. Command Mode: Configure mode
Logon to Configure Mode (Configure Terminal Mode).
The switch_a(config)# prompt will show on the screen.

switch_a(config)#

2. Usage:
Use this command to specify the maximum allowed hops for BPDU in an MST region. This
parameter is used by all the instances of the MST. Specifying the max hops for a BPDU
prevents the messages from looping indefinetely in the network. When a bridge receives a
MST BPDU that has exceeded the allowed max-hops, it discards the BPDU.

3. Command Syntax:
bridge GROUP max-hops HOP_COUNT
no bridge GROUP max-hops

GROUP <1-1> Specify the bridge-group ID.

HOP_COUNT Maximum hops the BPDU will be valid for.

4. Example:
The following example specifies the maximum allowed hops (25) for BPDU in bridge
GROUP (1):

switch_a(config)#bridge 1 max-hops 25
switch_a(config)#

IES-0880 User Manual Page 99

switch_a(config-mst)#

2. Usage:
Use this command to simultaneously add multiple VLANs for the corresponding instance
of a bridge. This command can be used only after the VLANs are defined. Use the no
parameter with this command to simultaneously remove multiple VLANs for the
corresponding instance of a bridge.

3. Command Syntax:
bridge GROUP instance INSTANCE_ID vlan VLAN_ID
no bridge GROUP instance INSTANCE_ID vlan VLAN_ID

GROUP <1-1> Specify the bridge-group ID.

INSTANCE_ID <1-15> Specify the instance ID.

2. Usage:
Use this command to set the bridge priority for an MST instance to the value specified. Use
the no parameter with this command to restore the default value of the bridge priority.
The lower the priority of the bridge, the better the chances are the bridge becoming a root
bridge or a designated bridge for the LAN. The priority values can be set only in
increments of 4096.

3. Command Syntax:
bridge GROUP instance INSTANCE_ID priority BRIDGE_PRIORITY
no bridge GROUP instance INSTANCE_ID priority
