Administrator Guide

You must configure the RADIUS group explicitly with the aaa radius group command in order for the AAA
servers to use the group of RADIUS servers. The 802.1x servers use the group of RADIUS servers based on the
VRF where the 802.1x request is received. As a result, it is possible that both globally configured RADIUS servers
as well as the group-configured RADIUS servers (without VRF or default VRF) are used for processing the 802.1x
requests that are received at the default VRF. The order in which the RADIUS servers are tried depends on the
order in which the RADIUS servers are configured.
The RADIUS accounting port acct-port port-number is configurable.
Example
DellEMC(config)#radius-server host 192.100.0.12
Force all logged-in users to re-authenticate (y/n)?
DellEMC(config)#no radius-server host 192.100.0.12
Force all logged-in users to re-authenticate (y/n)?
