Command Reference
The HWTACACS client (the router) and HWTACACS server use the MD5 algorithm to
encrypt the exchanged packets between them. The two ends verify the packets using
a shared key. Only when the same key is used can they properly receive the packets
and make responses. Thus, the shared key on the router must be the same with that
on the HWTACACS server.
