Chapter 1: Switch Management

Configuration Options

For advanced managem ent capability, the Management Module provides a
menu-driven system configuration program. T his pr ogram can be accessed by a
direct connection to the serial port on the rear panel (out-o f-band), or by a Telnet
connection over the netw ork (in-band).

The management agent is based on SNMP (Simple Network Management
Protocol). This SNMP agent permits the OmniStack
managed from any PC in t he ne twork using in-band mana gem ent software.

The management age nt also i ncludes an embedded HTTP Web agent. This Web
agent can be accessed using a standard Web browser from any computer attached
to the network.

The system configurat ion pr ogr am and the SNMP agent supp or t management
functions such as:

• Enable/disable any po rt

• Set the communicatio n m ode for any port

• Configure SNMP paramet er s

• Configure VLANs or multicast filtering

• Display system information or statistics

• Configure the switch to join a Spanning Tree

• Download system firmware

• Restart the system

Backup Management A gent

Note the following points about master and backup man agement agents:

• The OS-6148 with software version 3.0 supports a master management agent and
a backup management agent. The agent with the lower stack ID will be the master.
If the system up time of the m as te r is gr eater than 10 minutes, it down lo ads data
to the backup agent. Any configuration changes made to the master agent will be
synchronized with the backup agent within 1-2 minutes of the user selecting the
“apply” command.

• Up to a maximum of two Man agement Modules (one m as te r an d one back-up),
may exist wi t hin a stackab le configur ation, whi ch may consist of up to three
switches in a stack.

• The Management Modules (master or backup) cannot be “hot” inserted. The “hot”
removal of the master or the backup Management Module will cause system
instability and will requir e a m anual reboot of the entire stac k.

• The master manage m ent does not synchronize the ap pl icat i on software with that
of the backup manage m ent . T her ef ore, before insertion of the bac kup
Management Modul e, one must make sure that it co nt ains t he same application
software as the master Management Module (version 3.0 or greater). The master

®

6148 (OS-6148) to be

1-1

Switch Management

management only syn chr onizes the configuratio n file, in cluding any configuration
updates, with the back up m anagement.

• Upon the failure or “hot” removal of the master Manag em ent Module within a
stackable configurat io n, th e fo llo w ing occurs:

- A “Trap” is sent, a “Log event” is logged, the switch is re-booted and the backup

Management Modul e ta kes over without loss of conf ig ur at ion settings.

- The fail-over time of master management to that of the backup management in

a medium-size stackable configuration is appr oxi m at ely 2 minutes.
Consequently networ k t ra f fic is di sr upted during the fail-over pe riod.

- The backup management’s “Backup Master” state changes to a “Master” state

and the switch Unit IDs wi ll also reflect the new change.

- All ports will still be active and the switch will continue forwarding traffic in a

normal operative man ner .

- If a Management M od ul e w er e t o be re-installed, the newly-i nstal l ed

Management Modul e would assume the role of “Mast er ” ag ent with the
incumbent one chan ging status to that of “Backup M ast er” agent.

Closed-Loop Stack

Up to three OS-6148 sw itches can be stacked togethe r by installing optional
Stacking Modules. The OS-6100-RST-KIT Redundant Stacking Module kit allows
you to configure a closed-loop architecture that provides fault-tolerant operation of
the stack. If a switch or stacking module fails, or if a stacking cable is disconnected,
the entire stack will reboot and will subsequently resume normal operation and
management via the redundant stacking cable (Closed Loop). Also, any changes to
the stack including poweri ng d ow n of a unit or the insertion of a unit will cau se the
stack to reboot.

Note: The Redundant Stacking Module must be installed with the master Management

Module in Unit 1 only. If backup management is used in conjunction with the
closed-loop feature, the backup Management Module must be installed in Unit 2.

Required Connections

Console Port (Out-of-Band) Connections

Attach a VT100 compatible termin al or a PC running a terminal emulation pro gr am
to the serial port on the switch’s rear panel. Use the null-modem cable provided with
this package, or use a null modem connection that complies with the wiring
assignments shown in “Pin Ass i gnm ents” on page B-1 of this guide.

When attaching to a PC, set terminal emulation type to VT100, specify the port used
by your PC (i.e., COM 1~4), and t hen set communications to 8 data bits, 1 stop bit,
no parity, and 9600 bps (for initial configuration). Also be sure to set flow control to
“none.” (Refer to “Configu ring the Serial Port” on page 2-14 for a co m plet e
description of configuration options.)

Note: If the default settings for the management agent’s serial port have been

1-2

modified and you are having difficulty making a console connection, you can
display or modify the current settings using a Web browser as described under
“Console Configuration” on page 3-5.

In-Band Connections

Prior to accessing the Management Module via a network connection, you must first
configure it with a valid IP address, subnet mask, an d def ault gateway using an
out-of-band connection or the BOOTP protocol.

Note: By default BOOTP is disabled and the IP address is set to 192.168.10.1. To

enable BOOTP, see “IP Configuration” on page 2-11.

After configuring the switch’s IP paramet er s, you can access the on-boar d
configuration program from anywhere within the attached network. The on-board
configuration program can be accessed using Telnet from any computer attached to
the network. The switch and stack can also be managed b y any com puter using a
Web browser (Internet Explor er 4.0 , or N etsc ap e N avigator 4.0 or above), or from a
network com puter using network mana gement software.

Notes: 1. Use the Network Configuration menu to specify the maximum number of

simultaneous Telnet sessions that are supported by the system (up to four).

2. The on-board program only provides access to basic configuration functions.
To access the full range of SNMP management functions, you must use
SNMP-based network management software.

Netmask : 255.255.255.0

Default Gateway :

IP State : USER-CONFIG

<Apply> <Ok> <Cancel>

Use <TAB> or arrow keys to move, other keys to make changes.

Parameter Default Description

Interface Type Indicates that all interfaces on the switch are Ethernet. Management

IP packets from the switch are encapsulated within an Ethernet frame
for transmission over the Ethernet network.

IP Address 192.168.10.1 IP address of the stack you are managing. The system supports

SNMP over UDP/IP transport protocol. In this environment, all
systems on the Internet, such as network interconnection devices
and any PC accessing the agent module (or running management
software) must have an IP address.

Valid IP addresses consist of four decimal numbers, of 0 to 255,
separated by periods. Anything outside of this format will not be
accepted by the configuration program.

Netmask 255.255.255.0 Subnet mask of the switch you have selected. This mask identifies

the host address bits used for routing to specific subnets.

Default Gatew ay Gateway used to pass trap mes sag es f rom the sys tem ’s ag ent to t he

management station. Note that the gateway must be defined if the
management station is located in a different IP segment. No gateway
IP address is configured as the default.

IP State USER-CONFIG Specifies whether IP functionality is enabled via manual

configuration, or set by Boot Protocol (BOOTP). Options include:
USER-CONFIG - IP functionality is enabled based on the default or

user specified IP Configuration. (This is the default setting.)
BOOTP Get IP - IP is enabled but will not function until a BOOTP

reply has been received. BOOTP requests will be periodically
broadcast by the switch in an effort to learn its IP address. (BOOTP
values can include the IP address, default gateway, subnet mask,
and TFTP server IP.)

Management Setup Menu

Assigning SNMP Parameters

Use the SNMP Configur at io n sc re en t o di splay and modify parameters for the
Simple Network Managem ent Protocol (SNMP). The switch includes an on-board
SNMP agent which monitors the status of its hardware, as well as the traffic passing
through its ports. A computer attached to the network, called a Network
Management Station (NMS), can be used to access this information. Access rights
to the on-board agent are controlled by community strings. To communicate with the
switch, the NMS must firs t s ubm i t a val i d community string for authentication. The
options for configuring community strings and related trap functions are described in
the following sections.

Console Login Configuration

Use the Management Setup: Console Login Configuration to restrict management
access based on spec ified user names and passwords, or to se t the invalid
password threshold and time-out. There are only two user types defined, ADMIN
(Administrator) and GU EST, but you can set up to five different user names and
passwords. Only Adminis t rators have write access for param eters governing the
switch. You should therefore assign a user name and pass w or d t o th e default
Administrator as soon as po ssi ble, and store it in a safe place. (If for some reason
your password is lost, or you ca nnot gain access to the System Configuration
Program, contact Alcatel Technical Support for assistance.) The paramet er s shown
