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:
