Description

Required Information

This is an identification string between 1 and 79
characters (alpha and/or numeric) by which the
interface will be recognized by the system.

Multiple names are needed if multiple interfaces will
be configured.

AAA interfaces will be configured in the source
context.

AAA interface name

These will be assigned to the AAA interface.

Multiple addresses and/or subnets are needed if
multiple interfaces will be configured.

IP address and subnet

A single physical port can facilitate multiple
interfaces.

Physical port number

This is an identification string between 1 and 79
characters (alpha and/or numeric) by which the
physical port will be recognized by the system.

Multiple descriptions are needed if multiple ports will
be used.

Physical ports are configured within the source context
and are used to bind logical AAA interfaces.

Physical port description

Used when configuring static routes from the AAA
interface(s) to a specific network.
