Configuring 802.1X Authentication
Enterasys C3 Configuration Guide 32-19
Configuring 802.1X Authentication
Purpose
To review and configure 802.1X authentication for one or more ports using EAPOL (Extensible
Authentication Protocol). 802.1X controls network access by enforcing user authorization on
selected ports, which results in allowing or denying network access according to RADIUS server
configuration.
Commands
show dot1x
Use this command to display 802.1X status, diagnostics, statistics, and reauthentication or
initialization control information for one or more ports.
Syntax
show dot1x [auth-diag] [auth-stats] [port [init | reauth]] [port-string]
Parameters
Defaults
If no parameters are specified, 802.1X status will be displayed.
Note: To configure EAP pass-through, which allows client authentication packets to be forwarded
through the switch to an upstream device, 802.1X authentication must be globally disabled with the
set dot1x command (“set dot1x” on page 32-22).
