Configuring a TACACS+ Server

This task configures a TACACS+ server.
The port, if not specified, defaults to the standard port number, 49. The timeout and key parameters can
be specified globally for all the TACACS+ servers. The timeout specifies how long the AAA server waits
to receive a response from the TACACS+ server. The key specifies an authentication and encryption key
shared between the AAA server and the TACACS+ server.

Configuring AAA Services on Cisco IOS XR Software
Purpose
Configures the VRF reference of an AAA RADIUS
server group.
Private server IP addresses can overlap with
Note
those configured globally and the VRF
definitions can help to distinguish them.
Saves configuration changes.
When you issue the end command, the system
•
prompts you to commit changes:
Uncommitted changes found, commit them
before exiting(yes/no/cancel)?
[cancel]:
– Entering yes saves configuration changes to
the running configuration file, exits the
configuration session, and returns the
router to EXEC mode.
Entering no exits the configuration session
–
and returns the router to EXEC mode
without committing the configuration
changes.
Entering cancel leaves the router in the
–
current configuration session without
exiting or committing the configuration
changes.
Use the commit command to save the
•
configuration changes to the running
configuration file and remain within the
configuration session.
