Example usage:
To configure a TACACS+ authentication server host, with port number 4321, a timeout value of 12
seconds and a retransmit count of 4.
Description This command is used to configure a user-defined authentication server host
for the TACACS/XTACACS/TACACS+/RADIUS security protocols on the
switch. When a user attempts to access the switch with the authentication
protocol enabled, the switch will send authentication packets to a remote
TACACS/XTACACS/TACACS+/RADIUS server host on a remote host. The
TACACS/XTACACS/TACACS+/RADIUS server host will then verify or deny
the request and return the appropriate message to the switch. More than one
authentication protocol can be run on the same physical server host but,
remember that TACACS/XTACACS/TACACS+/RADIUS are separate entities
and are not compatible with each other. The maximum supported number of
server hosts is 16.
Parameters server_host <ipaddr> - The IP address of the remote server host the user
wishes to alter.
protocol – The protocol used by the server host. The user may choose one of
the following:
tacacs – Enter this parameter if the server host utilizes the TACACS protocol.
xtacacs - Enter this parameter if the server host utilizes the XTACACS
protocol.
tacacs+ - Enter this parameter if the server host utilizes the TACACS+
protocol.
radius - Enter this parameter if the server host utilizes the RADIUS protocol.
port <int 1-65535> - Enter a number between 1 and 65535 to define the virtual
port number of the authentication protocol on a server host. The default port
number is 49 for TACACS/XTACACS/TACACS+ servers and 1812 and 1813
for RADIUS servers but the user may set a unique port number for higher
security.
key <key_string 254> - Authentication key to be shared with a configured
TACACS+ or RADIUS server only. Specify an alphanumeric string up to 254
characters or choose none.
timeout <int 1-255> - Enter the time in seconds the switch will wait for the
server host to reply to an authentication request. The default value is 5
seconds.
retransmit <int 1-255> - Enter the value in the retransmit field to change how
many times the device will resend an authentication request when the server
does not respond. This field is inoperable for the TACACS+ protocol.
Restrictions Only Administrator-level users can issue this command.
#config authen server_host 10.1.1.121 protocol tacacs+ port 4321 timeout 12
