Chapter 29: 802.1x Port-based Network Access Control
628
Section IV: Security
❑ Set ports used to interconnect switches to the none role. This is
Figure 196. Port-based Authentication Across Multiple Switches
❑ When 802.1x Port-based Network Access Control is activated on a
switch, the feature polls all RADIUS servers specified in the
RADIUS configuration. If three servers have been configured, the
switch polls all three. If server 1 responds, all future requests go
only to that server. If server 1 stops responding, the switch again
polls all RADIUS servers. If server 2 responds, but not server 1, then
all future requests go to servers 1 and 2. If only server 3 responds,
then all future requests go to all three servers.
