2-6 User Guide for the Avaya P580 and P882 Multiservice Switches, v6.0
Chapter 2
Setting up a Management Interface
Before you can establish a Telnet session you must configure an IP interface
to allow management of the switch. Using the IP Interfaces Web page or a
CLI command, create an IP interface and set the IP Routing option to either
Routing/Mgmt or Mgmt Only. For more information on setting up an IP
interface on the switch, see “
Creating and Assigning IP Interfaces to the
VLAN ” in Chapter 12 , “ Configuring IP Routing .”
Establishing a Telnet Session
Once you have set up an IP interface and configured it to allow management
traffic, you can open a Telnet session to the switch. To open a Telnet
session, you must use one of the commercially available Telnet clients.
Launch the Telnet client application and open a Telnet session with the IP
address of the management interface. The switch will display its login
prompt.
If the TCP port for Telnet requests is set to a port number other than 23, you
must specify the TCP port number in addition to the IP address or host name
to start a Telnet session. For example, if you change the TCP port from 23 to
9998 on switch 192.168.0.126, enter telnet 192.168.0.126 9998 to start a
Telnet session. For information on how to change the TCP port for Telnet
requests, see “
Changing the TCP Ports for HTTP and Telnet ” later in this
chapter.
Once logged into the switch through a Telnet session, you can manage the
switch using CLI commands. For more information on CLI commands, see
the Command Reference Guide for the Avaya P580 and P882 Multiservice
Switches, Software Version 6.0.
Supported
Number of Telnet
Sessions
The Avaya Multiservice Switch supports a maximum of 6 concurrent Telnet
sessions. This number makes it possible for multiple network administrators
to connect to and manage the switch. However, if multiple Telnet sessions
are open, configuration changes from one session could be overwritten by
configuration changes from another.
* Note: Avaya recommends that you use one Telnet session at a time to
manage the switch.
Although it is possible to establish nested Telnet sessions, Avaya
recommends that you establish a separate Telnet session for each switch that
you want to manage. A nested Telnet session occurs when you establish a
Telnet session from a client to one switch, then through that session, open
another Telnet session to a second switch. Having a separate Telnet session
for each switch that you want to manage helps to avoid confusion.
