Usage
Information
To configure any number of RADIUS server hosts for each server host that is configured, use
this command. FTOS searches for the RADIUS hosts in the order they are configured in the
software.
The global default values for the timeout, retransmit, and key optional parameters are
applied, unless those values are specified in the radius-server host or other
commands. To return to the global default values, if you configure the timeout,
retransmit, or key values, include those keywords when using the no radius-
server host command syntax.
