To add a server group other than the ones listed, click the add button, revealing the following window to configure.

Figure 8- 12. Authentication Server Group Table Add Settings window

Enter a group name of up to 15 characters into the Group Name field and click Apply. The entry should appear in the

Authentication Server Group Settings window, as shown in Figure 8-12 (Trinity).

NOTE: The user must configure Authentication Server Hosts using the Authentication Server

Hosts window 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 three built in server groups can only have server hosts running the same TACACS

daemon. TACACS/XTACACS/TACACS+ protocols are separate entities and are not compatible

with each other.

Authentication Server Host

This window will set user-defined Authentication Server Hosts for the TACACS / XTACACS / TACACS+ / 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 / 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.

To view the following window, click Security Management > Access Authentication Control > Authentication Server
