xStack DES-6500 Modular Layer 3 Chassis Ethernet Switch User Manual
Authentication Server Host
This window will set user-defined
Authentication Server Hosts
for the TACACS / XTACACS / / 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 / / RADIUS server host on a remote host. The TACACS /
XTACACS / / 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 / / RADIUS are separate entities and are not compatible with each other. The maximum supported number
of server hosts is 16.
