config authen server_host
Purpose Used to configure a user-defined authentication server host.
Syntax
create authen server_host <ipaddr> protocol [tacacs | xtacacs |
tacacs+ | radius] {port <int 1-65535> | key [<key_string 254> | none] |
timeout <int 1-255> | retransmit <1-255>}
Description This command will 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.
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.
