Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display the current EAP-based security status:

    • show eapol auth-stats interface [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

    • show eapol port {interface [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}] | {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}}

    • show eapol session-stats interface [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

    • show eapol sessions {eap | neap} [vlan <1-4059>] [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]} [verbose]

    • show eapol summary port [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

    • show eapol system

Variable Definitions

The following table defines parameters for the show eapol command.

Variable

Value

auth-stats [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays the authentication statistics interface.

Note:

auth-stats [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}] is useful only for EAP supplicants. The command output changes only when the EAP supplicant tries to access the network.

port {interface [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}] | {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}}

Specifies the ports to display. If no port is entered, all ports are displayed.

session-stats interface [gigabitEthernet {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays the authentication session statistics interface.

sessions {eap | neap} [vlan<1-4059>] [{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}] [verbose]

Displays EAP and non-EAP authentication sessions on the port.

summary port[{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}]

Displays EAP and NEAP clients.

system

Displays EAP settings.
