Administrator Guide

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.
Example
Dell(conf)#radius-server group group1
Dell(conf-radius-group)#radius-server host 1.1.1.1 key secret
Dell(conf-radius-group)#no radius-server host 1.1.1.1
