Ethernet Switch CLI Reference Guide
127
29.2 Command Examples
This example enables L2PT on the Switch and sets the destination MAC address for
encapsulating layer 2 protocol packets received on an access port.
This example enables L2PT for STP, CDP and VTP packets on port 3. It also sets L2PT mode
to access for this port.
This example sets L2PT mode to tunnel for port 4.
This example displays L2PT settings and status on port 3. You can also see how many CDP,
STP, VTP, LACP, PAgP and UDLD packets received on this port are encapsulated,
decapsulated or dropped.
