Setting the Shared Key for HWTACACS Packets
When using an 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.
