Configuring Switch Ports To Operate As
Supplicants for 802.1X Connections to
Other Switches
You can configure a switch port to operate as a supplicant in a connection to
a port on another 802.1X-aware switch to provide security on links between
802.1X-aware switches. (Note that a port can operate as both an authenticator
and a supplicant.)
For example, suppose that you want to connect two switches, where:
■ Switch “A” has port A1 configured for 802.1X supplicant operation
■ You want to connect port A1 on switch “A” to port B5 on switch “B”.
