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. 
For security purposes, all shared keys, including shared keys configured in plain text, are saved in 
ciphertext. 
Examples 
# Specify a secondary authentication server with IP address 10.163.155.13, TCP port number 49, and 
plaintext shared key 123456TESTauth&! for HWTACACS scheme hwt1 
<Sysname> system-view 
[Sysname] hwtacacs scheme hwt1 
[Sysname-hwtacacs-hwt1] secondary authentication 10.163.155.13 49 key simple 
123456TESTauth&!

Parameters 
ipv4-address: Specifies the IPv4 address of the secondary HWTACACS authorization server. 
ipv6 ipv6-address: Specifies the IPv6 address of the secondary HWTACACS authorization server. 
port-number: Specifies the service port number of the secondary HWTACACS authorization server. The 
value range for the TCP port number is 1 to 65535, and the default setting is 49. 
key  {  cipher | simple } string: Sets the shared key for secure communication with the secondary 
HWTACACS authorization server. 
•  cipher string: Sets a ciphertext shared key. The string argument is case sensitive. 
{  In non-FIPS mode, the key is a string of 1 to 373 characters.
