Viewing session information for MAC authenticated clients on a switch
Syntax:
show port-access mac-based clients [port-list]
Displays the session status, name, and address for each MAC authenticated client on the switch. The IP address displayed is taken from the DHCP binding table (learned through the DHCP Snooping feature).
If DHCP snooping is not enabled on the switch,
n/a (not available) is displayed for a client's IP address.
If a MAC-authenticated client uses an IPv6 address,
n/a - IPv6 is displayed.
If DHCP snooping is enabled but no MAC-to-IP address binding for a client is found in the DHCP binding table,
n/a
- no info is displayed.
