Simply enter a group name of no more than 15 alphanumeric characters to define the user group to add.
After clicking Apply, the new user-defined group will be displayed in the Server Group table. Here, it can be
configured as the user desires.
The Switch has two built-in Authentication Server Groups that cannot be removed but can be modified. To
modify a particular group, click Edit button, which will then display the following window.
Figure 4.133 – Security > Access Authentication control > Authentication Server Group-Edit
Select Group Name, Protocol and IP address then click Add to implement the changes.
NOTE: The user must configure Authentication
Server Hosts using the Authentication Server
Hosts page before adding hosts to the list.
Authentication Server Hosts must be configured
for their specific protocol on a remote centralized
server before this function can work properly.
NOTE: The two built in server groups can only
have server hosts running the same TACACS
daemon. The TACACS+ and RADIUS protocols
are separate entities and are not compatible with
each other.
Security > Access Authentication Control > Authentication Server
This Authentication Server page will set user-defined Authentication Server Hosts for the TACACS+ and
RADIUS security protocols on the Switch. When a user attempts to access the Switch with Authentication
Policy enabled, the Switch will send authentication packets to a remote TACACS+ or RADIUS server host on
a remote host. The TACACS+ or 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+ and RADIUS are separate entities and are not compatible with
each other. The maximum supported number of server hosts is 16.
