RADIUS Client
Remote Authentication Dial-in User Service (RADIUS) is a logon
authentication protocol that uses software running on a central server to
control access to RADIUS-aware devices on the network. An
authentication server contains a database of multiple user name/password
pairs with associated privilege levels for each user or group that require
management access to a switch.
radius-server host
This command specifies primary and backup RADIUS servers and
authentication parameters that apply to each server. Use the no form to
restore the default values.
Syntax
[no] radius-server index host {host_ip_address | host_alias}
[auth-port auth_port] [timeout timeout] [retransmit retransmit]

queried in sequence until a server responds or the retransmit period
expires.
