Sets the forwarding database aging time in seconds.
: 10-3600 in seconds
aging-time
Displays the forwarding database aging time.
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.
Turns off anti-spoofing action so the IES does not shut down UNI
ports upon which it detects 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.
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.
