create authen server_host
1-255> | retransmit < 1-255>}
Description
This command is used to create an authentication server host for the
TACACS/XTACACS/TACACS+/RADIUS security protocols on the Switch.
When a user attempts to access the Switch with 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 to add.
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.
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.
Restrictions
Only Administrator-level users can issue this command.
Example usage:
To create a TACACS+ authentication server host, with port number 1234, a timeout value of 10 seconds and a retransmit count of
5.
