H3C S6812 Series Command Reference Manual page 1748

If you do not specify any parameters for the undo secondary accounting command, the command
removes all secondary accounting servers.
Two accounting servers specified for a scheme, primary or secondary, cannot have identical IP
address and port number settings.
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 accounting server only when it is not used for user accounting. Removing an
accounting server affects only accounting processes that occur after the remove operation.
Examples
# In HWTACACS scheme hwt1, specify a secondary accounting server with IP address
10.163.155.12, TCP port number 49, and plaintext shared key 123456TESTacct&!.

Parameters
ipv4-address: Specifies the IPv4 address of the secondary HWTACACS authentication server.
ipv6 ipv6-address: Specifies the IPv6 address of the secondary HWTACACS authentication server.
port-number: Specifies the service port number of the secondary HWTACACS authentication server.
The value range for the TCP port number is 1 to 65535. The default setting is 49.
key: Specifies the shared key for secure communication with the secondary HWTACACS
authentication server.
cipher: Specifies the key in encrypted form.
