Article summary

L2CP CLI commands are categorized as follows:

Configuration Commands

This section includes L2CP configuration commands.

l2protocol-passthrough

Command Objective:
This command sets the option to pass through L2 protocol packets transparently received on the port.

Syntax:
l2protocol-passthrough {dot1x | lacp | stp | gvrp | gmrp| igmp | mvrp | mmrp | elmi | lldp | ecfm | eoam }

Parameter Description:

  • dot1x - Passthrough Dot1x PDUs transparently received on on this port
  • lacp - Passthrough LACP PDUs transparently received on this port
  • stp - Passthrough STP PDUs transparently received on this port
  • gvrp - Passthrough GVRP BPDUs transparently received on on this port
  • gmrp - Passthrough GMRP BPDUs transparently received on on this port
  • igmp - Passthrough IGMP Packets transparently received on on this port
  • mvrp - Passthrough MVRP PDUs transparently received on on this port
  • mmrp - Passthrough MMRP PDUs transparently received on on this port
  • elmi - Passthrough ELMI PDUs transparently received on on this port
  • lldp - Passthrough LLDP PDUs transparently received on on this port
  • ecfm - Passthrough ECFM PDUs transparently received on on this port
  • eoam - Passthrough EOAM PDUs transparently received on on this port

Mode:
Interface Configuration mode (Physical / Port channel)

Default:
Based on the port type


Note: To enable L2 protocol passthrough:

The port must be customer edge port / customer network port / proprietary customer edge port / proprietary customer network port/access port / provider network port / provider network port three-tagged.

The protocol should be disabled on the port, except for IGMP and Dot1x protocol, which have to be disabled globally.


Example:

Your Product(config-if)# l2protocol-passthrough eoam

l2protocol-tunnel

Command Objective:
This command enables the tunneling of L2 protocols on this port.

The no form of the command disables the tunneling of L2 protocols on this port.

Syntax:
l2protocol-tunnel {dot1x | lacp | stp | gvrp | gmrp| igmp | mvrp | mmrp | elmi | lldp | ecfm | eoam }

no { l2protocol-peer | l2protocol-discard | l2protocol-tunnel | l2protocol-passthrough }{dot1x | lacp | stp | gvrp | gmrp| igmp | mvrp | mmrp | elmi | lldp | ecfm | eoam}

Parameter Description:

  • l2protocol-peer - Disables L2 protocol peer on the port
  • l2protocol-discard - Disables L2 protocol peer on the port
  • l2protocol-passthrough - Disables L2 protocol passthrough on the port
  • dot1x - Enables the tunneling of L2 protocols for Dot1x PDUs
  • lacp - Enables the tunneling of L2 protocols for LACP PDUs
  • stp - Enables the tunneling of L2 protocols for STP BPDUs
  • gvrp - Enables the tunneling of L2 protocols for GVRP BPDUs
  • gmrp - Enables the tunneling of L2 protocols for GMRP BPDUs
  • igmp - Enables the tunneling of L2 protocols for IGMP Packets
  • mvrp - Enables the tunneling of L2 protocols for MVRP PDUs
  • mmrp - Enables the tunneling of L2 protocols for MMRP PDUs
  • elmi - Enables the tunneling of L2 protocols for ELMI PDUs
  • lldp - Enables the tunneling of L2 protocols for LLDP PDUs
  • ecfm - Enables the tunneling of L2 protocols for ECFM PDUs
  • eoam - Enables the tunneling of L2 protocols for EOAM PDUs

Mode:
Interface Configuration mode (Physical / Port channel)

Default:
Based on the port type


Note: To enable L2 protocol tunneling:

The port must be customer edge port / customer network port / proprietary customer edge port / proprietary customer network port/access port.

The protocol should be disabled on the port, except for IGMP and Dot1x protocol, which have to be disabled globally.


Example:

Your Product(config-if)# l2protocol-tunnel dot1x

l2protocol-tunnel cos

Command Objective:
This command configures the priority for the tunneled STP BPDUs. This value ranges from 0 to 7.
The no form of the command configures the default priority for the tunneled STP BPDUs.

Syntax:
l2protocol-tunnel cos <cos-value(0-7)>
no l2protocol-tunnel cos

Mode:
Global Configuration Mode / Switch Configuration Mode

Default:
cos - value - 7

Prerequisites:
The configured priority value will be effective only when the L2 Protocol tunnel STP is enabled on an interface

Example:

Your Product(config)# l2protocol-tunnel cos 5

l2protocol-tunnel override

Command Objective:
This command enables or disables the Layer 2 control protocol (L2CP) tunnel Override option.

Syntax:
l2protocol-tunnel override { enable | disable }

Parameter Description:

  • enable - Enables L2CP tunnel Override option. This implies that tunnel status for all the Layer 2 control protocols is referred from the port table.
  • disable - Disables L2CP tunnel Override option. This implies that tunnel status for all the Layer 2 control protocols operating over a vlan is referred from the VLAN table.

Mode:
Interface Configuration mode (Physical / Port channel)

Default:
disable

Example:

Your Product(config-if)# l2protocol-tunnel override disable
