Oops!
SHOW IP ALIAS is used to collect addresses. Your question was about the
config mode command :}
Here is some verbiage from the command reference:
Usage Guidelines
A user attempting to establish a connection is connected to the first free
line in a rotary group using the Telnet protocol.
The IP address must be on the same network or subnet as the main address of
the terminal server, and must not be used by another host on that network or
subnet. Connecting to the IP address has the same effect as connecting to the
main address of the router, using the argument tcp-port as the TCP port.
You can use the ip alias command to assign multiple IP addresses to the
router. For example, in addition to the primary alias address, you can specify
addresses that correspond to lines or rotary groups. Using the ip alias
command in this way makes connection to a specific rotary group transparent to
the user.
When asynchronous mode is implemented, the Cisco IOS software creates the
appropriate IP aliases, which map the asynchronous addresses for the lines to
which they are connected. This process is automatic and does not require
configuration.
Examples
The following example configures connections to IP address 172.30.42.42 to act
identically to connections made to the primary IP address of the server on TCP
port 3001. In other words, a user is connected to the first free line on port
1 of the rotary group that uses the Telnet protocol.
ip alias 172.30.42.42 3001

Subject: ip alias
Hi group,
What is the correct usage of the ip alias command. I was once told it
can be useful in the lab. Any thoughts?
TIA
Ray
R1(config)#ip alias ?
A.B.C.D IP address to alias to a port
