TACACS+ parameters
TACACS configuration parameters
Primary TACACS+ Server
Hostname or IP address of Server a.b.c.d Port n
The IP address or hostname of the primary TACACS+ server is entered into the left-hand text
box. If required a port number may also be specified using the right-hand text box. TACACS+
uses TCP port 49 by default. Entering a different number into this text box will cause the
router to use that port instead. The port number is used by both the primary and secondary
TACACS+ servers.
Server Key
The encryption key to use when communicating with the primary server.
Confirm Server Key
The key is typed into this text box to allow the router to confirm that the two strings are
identical.
Secondary TACACS+ Server
Hostname or IP address of Server
The IP address or hostname of the secondary (backup) TACACS+ server. This will be used if a
socket to the primary server cannot be opened.
Server Key
The encryption key to use when communicating with the secondary server.
Confirm Server Key
Enter the key into this text box to allow the router to confirm that the two entries are identical.
Enable local authentication if there is no response from the server(s)
When checked, this checkbox will allow local authentication if TACACS+ authentication fails.
Enable TACACS+ Authentication
When checked, this checkbox enables authentication. When authentication is enabled, user
authentication takes place on the TACACS+ server. When disabled, user authentication takes
place locally on the router.
Enable TACACS+ Authorisation
When checked, this checkbox enables authorization which means that authorization of the
application takes place and authorization of application-related commands also takes place.
Enable TACACS+ Accounting
When checked, this checkbox enables accounting. When accounting is enabled, accounting
messages are sent at the start and end of application sessions, where applicable, and update
messages are also sent from command sessions when commands are denied locally or after
they are executed.
