L2Protocol-Tunnel - Cisco Catalyst Blade Switch 3130 Reference Manual

l2protocol-tunnel

l2protocol-tunnel
Use the l2protocol-tunnel interface configuration command on the switch stack or on a standalone
switch to enable tunneling of Layer 2 protocols on an access port, IEEE 802.1Q tunnel port, or a port
channel. You can enable tunneling for Cisco Discovery Protocol (CDP), Spanning Tree Protocol (STP),
or VLAN Trunking Protocol (VTP) packets. You can also enable point-to-point tunneling for Port
Aggregation Protocol (PAgP), Link Aggregation Control Protocol (LACP), or UniDirectional Link
Detection (UDLD) packets. Use the no form of this command to disable tunneling on the interface.

Enable point-to-multipoint tunneling of CDP, STP, and VTP packets.
(Optional) Enable tunneling of CDP, specify a shutdown threshold for CDP, or
specify a drop threshold for CDP.
(Optional) Enable tunneling of STP, specify a shutdown threshold for STP, or
specify a drop threshold for STP.
(Optional) Enable tunneling or VTP, specify a shutdown threshold for VTP, or
specify a drop threshold for VTP.
(Optional) Enable point-to point tunneling of PAgP, LACP, and UDLD packets.
(Optional) Enable point-to-point tunneling of PAgP, specify a shutdown
threshold for PAgP, or specify a drop threshold for PAgP.
(Optional) Enable point-to-point tunneling of LACP, specify a shutdown
threshold for LACP, or specify a drop threshold for LACP.
(Optional) Enable point-to-point tunneling of UDLD, specify a shutdown
threshold for UDLD, or specify a drop threshold for UDLD.
packets per second to be received before an interface is shut down.
(Optional) Set a drop threshold for the maximum rate of Layer 2 protocol
packets per second to be received before an interface drops packets.
Specify a threshold in packets per second to be received for encapsulation
before the interface shuts down, or specify the threshold before the interface
drops packets. The range is 1 to 4096. The default is no threshold.
