servers. If you do this, the system will prompt that the configuration fails.

z

You can remove a server only when it is not used by any active TCP connection for sending

accounting messages.

Configuring Shared Keys for HWTACACS Messages

When using a TACACS server as an AAA server, you can set a key to improve the communication

security between the switch and the TACACS server.

The TACACS client and server adopt MD5 algorithm to encrypt HWTACACS messages before they are

exchanged between the two parties. The two parties verify the validity of the HWTACACS messages

received from each other by using the shared keys that have been set on them, and can accept and

respond to the messages only when both parties have the same shared key.
