If a source MAC address is locked at a port (statically configured),

the switch filters frames that have that source MAC if they are

received on any port in the same VLAN. The switch can also

generate traps to identify all unknown source addresses. Traps for

unknown source addresses are generated every intrusion trap timer

interval. The default value of the timer is 30 minutes.

The switch keeps a history of intruding source MAC addresses. A

history of 64 such addresses is stored in a software buffer at a time.

The switch stores the source MAC address and sends a trap for an

unknown MAC address, every intrusion trap timer interval. Once

the MAC address is stored and the trap is sent, the switch does not

send a trap for this MAC address again, until that MAC address is

flushed from the buffer.

* Note: You can set the trap timer within a range of 60

to 1800 seconds (default) in one second
