H3C S6812 Series Command Reference Manual page 1745

As a best practice, specify the single-connection keyword to reduce TCP connections for improving
system performance if the HWTACACS server supports the single-connection method.
You can remove an authentication server only when it is not used for user authentication. Removing
an authentication server affects only authentication processes that occur after the remove operation.
Examples
# In HWTACACS scheme hwt1, specify the primary authentication server with IP address
10.163.155.13, TCP port number 49, and plaintext shared key 123456TESTauth&!.

key: Specifies the shared key for secure communication with the primary HWTACACS authorization
server.
cipher: Specifies the key in encrypted form.
