Disabling Aging For Authenticated Mac Addresses - Dell PowerConnect B-RX Configuration Manual

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.

Disabling aging for authenticated MAC addresses

MAC addresses that have been authenticated or denied by a RADIUS server are aged out if no
traffic is received from the MAC address for a certain period of time.

Authenticated MAC addresses or non-authenticated MAC addresses that have been placed in
the restricted VLAN are aged out if no traffic is received from the MAC address over the
device's normal MAC aging interval.
Non-authenticated MAC addresses that are blocked by the device are aged out if no traffic is
received from the address over a fixed hardware aging period (70 seconds), plus a
configurable software aging period. (See the next section for more information on configuring
the software aging period).
