What to Do Next
After configuring TACACS+ servers, configure TACACS+ server groups. (See the “Configuring
TACACS+ Server Groups” section.)
Step 5
tacacs-server host host-name single-connection
Example:
RP/0/RP0/CPU0:router(config)# tacacs-server
host 209.165.200.226 single-connection
Prompts the router to multiplex all TACACS+ requests to
this server over a single TCP connection. By default, a
separate connection is used for each session.
Step 6
tacacs source-interface type instance
Example:
RP/0/RP0/CPU0:router(config)# tacacs
source-interface POS 0/4/0/0
(Optional) Specifies the source IP address of a selected
interface for all outgoing TACACS+ packets.
• The specified interface or subinterface must have an IP
address associated with it. If the specified interface or
subinterface does not have an IP address or is in the
down state, then TACACS+ reverts to the default. To
avoid this, add an IP address to the interface or
subinterface or bring the interface to the up state.
Step 7
Repeat Step 2. through Step 5. for each external server
to be configured.

Step 8
end
or
commit
Example:
RP/0/RP0/CPU0:router(config)# end
or
RP/0/RP0/CPU0:router(config)# commit
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.
Step 9
show tacacs
Example:
RP/0/RP0/CPU0:router# show tacacs
(Optional) Displays information about the TACACS servers
that are configured in the system.
