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 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 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 or RADIUS server host on
a remote host. The 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 and RADIUS are separate entities and are not compatible with
each other. The maximum supported number of server hosts is
16
.
