Using Telnet

Telnet may be used to log into the switch from a remote station. All of the standard Telnet commands are
supported by software in the switch. When Telnet is used to log in, the switch is acting as a Telnet server.

A Telnet session may also be initiated from the switch itself during a login session. In this case, the switch
is acting as a Telnet client.

Logging Into the Switch Via Telnet

Before you can log into the OmniSwitch using a Telnet interface, the telnet option of the

aaa

authentication

command must be enabled. Once enabled, any standard Telnet client may be used to log

into the switch. To log into the switch, open your Telnet application and enter the switch’s IP address (the
IP address will typically be the same as the one configured for the EMP). The switch’s welcome banner
and login prompt display.

Note. A Telnet connection is not secure. Secure Shell is recommended instead of Telnet or FTP as a
secure method of accessing the switch.

Starting a Telnet Session from the Switch

At any time during a login session on the switch, you can initiate a Telnet session to another switch (or
some other device) by using the

telnet

CLI command and the relevant IP address. The following shows an

example of telnetting to another OmniSwitch with an IP address of 10.255.10.123.

-> telnet 10.255.10.123

Trying 10.255.10.123...

Connected to 10.255.10.123.

Escape character is '^]'.

Here, you must enter a valid username and password. Once login is completed, the OmniSwitch welcome
banner will display as follows:
