C 13
show fdb aging-time
Displays the forwarding database aging time. E 13
fdb disable-anti-spoofing
Turns off MAC spoofing protection. The IES issues an alarm and an
SNMP trap when it learns a MAC address on a second UNI port.
The IES still forwards packets from other ports destined for the
spoofed MAC to the later UNI port. C 13
fdb disable-spoofing-action
Turns off anti-spoofing action so the IES does not shut down UNI
ports upon which it detects spoofing. C 13
no fdb disable-anti-spoofing
Turns on MAC spoofing protection. The IES issues an alarm and an
SNMP trap when it learns a MAC address on a second UNI port.
The subscriber device with a spoofed MAC cannot send packets to
other ports.
If anti-spoofing action is also turned on, anti-spoofing deactivates
the second UNI port upon which it detects a MAC address.
C 13
no fdb disable-spoofing-action
Turns on anti-spoofing action so the IES deactivates UNI ports
upon which it detects MAC address spoofing. For DSL ports, use
the
interface dsl < slot/portlist >
and
active
commands to
re-activate the UNI port.
Note: Anti-spoofing must also be enabled for this to take effect.
