Name

ip alias — global

Synopsis

ip alias ip-address port
no ip alias ip-address

Configures

IP address mapping for reverse telnet

Default

None

Description

This command allows you to provide aliases in the form of IP addresses for various ports on the router. This feature is helpful if you are configuring a communication server with reverse telnet.

ip-address

The IP address of the port for which you want to establish an alias.

port

The port that you want to use as an alias for the IP address.

Example

Say we have a communication server (router) with three ports to which we allow reverse telnet access: 2001, 2002, and 2003. Instead of requiring users to type the router’s IP address and the port every time, we assign (alias) an available IP address to each of our ports. The following commands create three IP address aliases (172.30.1.1, 172.30.1.2, and 172.30.1.3):

ip alias 172.30.1.1 2001
ip alias 172.30.1.2 2002
ip alias 172.30.1.3 2003
