About Bypassing a Nonresponsive Server

As of Cisco SAN-OS Release 3.0(1), you can bypass a nonresponsive AAA server within a server group.
If the switch detects a nonresponsive server, it will bypass that server when authenticating users. Use
this feature to minimize login delays caused by a faulty server. Instead of sending a request to a
nonresponsive server and waiting for the authentication request to timeout, the switch sends the
authentication request to the next server in the server group. If there are no other responding servers in
the server group, the switch continues to attempt authentications against the nonresponsive server.

AAA Server Distribution

Configuration for RADIUS and TACACS+ AAA on an MDS switch can be distributed using the Cisco
Fabric Services (CFS). The distribution is disabled by default (see
Infrastructure").
After enabling the distribution, the first server or global configuration starts an implicit session. All
server configuration commands entered thereafter are stored in a temporary database and applied to all
switches in the fabric (including the originating one) when you explicitly commit the database. The
various server and global parameters are distributed, except the server and global keys. These keys are
unique secrets to a switch and should not be shared with other switches.
Server group configurations are not distributed.
