In FIPS mode, the encrypted form of the key is a string of 15 to 373 characters. The plaintext
form of the key is a string of 15 to 255 characters. The plaintext string must contain digits,
uppercase letters, lowercase letters, and special characters.
single-connection: The device and the primary HWTACACS authorization server use the same
TCP connection to exchange all authorization packets for all users. If you do not specify this keyword,
the device establishes a new TCP connection each time it exchanges authorization packets with the
primary authorization server for a user.
Usage guidelines
Make sure the port number and shared key settings of the primary HWTACACS authorization server
are the same as those configured on the server.
Two authorization 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 authorization server only when it is not used for user authorization. Removing an
authorization server affects only authorization processes that occur after the remove operation.
Examples
# In HWTACACS scheme hwt1, specify the primary authorization server with IP address
10.163.155.13, TCP port number 49, and plaintext shared key 123456TESTautr&!.
