Setting the Shared Key for HWTACACS Packets
When using a HWTACACS server as an AAA server, you can set a key to secure the communications
between the device and the HWTACACS server.
The HWTACACS client and HWTACACS server use the MD5 algorithm to encrypt packets exchanged
between them and a shared key to verify the packets. Only when the same key is used can they
properly receive the packets and make responses.
Follow these steps to set the shared key for HWTACACS packets:
