Tacacs+ Configuration Example - Dell PowerConnect M6348 Configuration Manual

TACACS+ Configuration Example

This example configures two TACACS+ servers at 10.10.10.10 and 11.11.11.11. Each server has a unique
shared secret key. The server at 10.10.10.10 has a default priority of 0, the highest priority, while the other
server has a priority of 2. The process creates a new authentication list, called tacacsList, which uses
TACACS+ to authenticate, and uses local authentication as a backup method.
Figure 5-5. PowerConnect M6220/M6348/M8024 Switches with TACACS+
When a user attempts to log into the switch, the NAS or switch prompts for a username and password.
The switch attempts to communicate with the highest priority configured TACACS+ server at
10.10.10.10. Upon successful connection with the server, the switch and server exchange the login
credentials over an encrypted channel. The server then grants or denies access, which the switch honors,
and either allows or does not allow the user to gain access to the switch. If neither of the two servers can
be contacted, the switch searches its local user database for the user.
