config authen server_group
Purpose Used to configure a user-defined authentication server group.
Syntax
config authen server_group [tacacs | xtacacs | tacacs+ | radius | <string 15>] [add |
delete] server_host <ipaddr> protocol [tacacs | xtacacs | tacacs+ | radius]
Description This command will configure an authentication server group. A server group is a
technique used to group TACACS/XTACACS/TACACS+/RADIUS server hosts into user
defined categories for authentication using method lists. The user may define the type of
server group by protocol or by previously defined server group. Up to eight (8)
authentication server hosts may be added to any particular group
server_group - The user may define the group by protocol groups built into the Switch
Parameters
(TACACS/XTACACS/TACACS+/RADIUS), or by a user-defined group previously created
using the create authen server_group command.
add/delete – Enter the correct parameter to add or delete a server host from a server
group.
server_host <ipaddr> - Enter the IP address of the previously configured server host to
add or delete.
protocol – Enter the protocol utilized by the server host. There are three options:
Restrictions Only administrator-level users can issue this command.
DES-3550 Layer 2 Fast Ethernet Switch
tacacs – Use this parameter to utilize the built-in TACACS server protocol on the
Switch. Only server hosts utilizing the TACACS protocol may be added to this
group.
xtacacs – Use this parameter to utilize the built-in XTACACS server protocol on
the Switch. Only server hosts utilizing the XTACACS protocol may be added to
this group.
tacacs+ – Use this parameter to utilize the built-in TACACS+ server protocol on
the Switch. Only server hosts utilizing the TACACS+ protocol may be added to
this group.
radius – Use this parameter to utilize the built-in RADIUS server protocol on the
Switch. Only server hosts utilizing the RADIUS protocol may be added to this
group.
<string 15> - Enter an alphanumeric string of up to 15 characters to define the
previously created server group. This group may add any combination of server
hosts to it, regardless of protocol.
tacacs – Use this parameter to define the protocol if the server host is using the
TACACS authentication protocol.
xtacacs – Use this parameter to define the protocol if the server host is using the
XTACACS authentication protocol.
tacacs+ – Use this parameter to define the protocol if the server host is using
the TACACS+ authentication protocol.
radius – Use this parameter to define the protocol if the server host is using the
RADIUS authentication protocol.
