Configuration File; Clearing Authenticated Mac Addresses - Dell PowerConnect B-RX Configuration Manual

31
Configuring multi-device port authentication
The port-configured-vlan keyword removes the port from its RADIUS-assigned VLAN and places it
back in the VLAN where it was originally assigned. This is the default.
The port-restrict-vlan keyword removes the port from its RADIUS-assigned VLAN and places it in the
restricted VLAN.
The system-default-vlan keyword removes the port from its RADIUS-assigned VLAN and places it in
the DEFAULT-VLAN.
Saving dynamic VLAN assignments to the running

configuration file

You can configure the device to save the RADIUS-specified VLAN assignments to the device's
running configuration file. To do this, enter the following command.
BigIron RX(config)# mac-authentication save-dynamicvlan-to-config
Syntax: [no] mac-authentication save-dynamicvlan-to-config
By default, the dynamic VLAN assignments are not saved to the running configuration file. Entering
the show running-config command does not display dynamic VLAN assignments, although they can
be displayed with the show vlan and show auth-mac-address detail commands.

Clearing authenticated MAC addresses

The device maintains an internal table of the authenticated MAC addresses (viewable with the
show authenticated-mac-address command). You can clear the contents of the authenticated MAC
address table either entirely, or just for the entries learned on a specified interface. In addition, you
can clear the MAC session for an address learned on a specific interface.
To clear the entire contents of the authenticated MAC address table, enter the following command.
BigIron RX(config)# clear auth-mac-table
Syntax: clear auth-mac-table
To clear the authenticated MAC address table of entries learned on a specified interface, enter a
command such as the following.
BigIron RX(config)# clear auth-mac-table e 3/1
Syntax: clear auth-mac-table <slot>/<portnum>
To clear the MAC session for an address learned on a specific interface, enter commands such as
the following.
BigIron RX(config)# interface e 3/1
BigIron RX(config-if-e100-3/1)# mac-authentication clear-mac-session
00e0.1234.abd4
Syntax: mac-authentication clear-mac-session <mac-address>
This command removes the Layer 2 CAM entry created for the specified MAC address. If the device
receives traffic from the MAC address again, the MAC address is authenticated again.
