Configuring L2CP Tunneling
This section describes the commands used to configure Layer 2 Protocol Tunneling (L2PT).
l2protocol-tunnel tunnel-dmac
This command configures the destination address for Layer 2 Protocol Tunneling (L2PT). Use the no
form to restore the default setting.
Syntax
l2protocol-tunnel tunnel-dmac mac-address
mac-address – The switch rewrites the destination MAC address in all upstream L2PT
protocol packets (i.e, STP BPDUs) to this value, and forwards them on to uplink ports. The
MAC address must be specified in the format xx-xx-xx-xx-xx-xx or xxxxxxxxxxxx.
Default Setting
01-12-CF-.00-00-02, proprietary tunnel address
Command Mode
Global Configuration
Command Usage
•
When L2PT is not used, protocol packets (such as STP) are flooded to 802.1Q access ports on
the same edge switch, but filtered from 802.1Q tunnel ports. This creates disconnected
protocol domains in the customer’s network.
•
L2PT can be used to pass various types of protocol packets belonging to the same customer
transparently across a service provider’s network. In this way, normally segregated network
segments can be configured to function inside a common protocol domain.
