display l2protocol-tunnel statistics

Function

The display l2protocol-tunnel statistics command displays statistics about tunneled Layer 2 protocol data units (PDUs) on an interface.

Format

display l2protocol-tunnel statistics { interface-type interface-number | interface-name } [ { protocol } &<1-19> ]

Parameters

Parameter	Description	Value
interface-type	Specifies the interface type.	The value is a string of 1 to 63 case-insensitive characters, spaces not supported.
interface-number	Specifies the interface number.	-
interface-name	Specifies the interface name.	The value is a string of 1 to 63 case-insensitive characters, spaces not supported.
protocol	Displays statistics about tunneled Layer 2 PDUs of a specified protocol on an interface.	The protocol as follows: stp lacp dtp gmrp gvrp lldp vtp udld pagp cdp eoam3ah dldp mvrp mmrp e-lmi sstp One or up to all of the preceding Layer 2 protocols can be specified.

Usage Guidelines

Usage Scenario

After you configure Layer 2 protocol tunneling, run the display l2protocol-tunnel statistics command to view statistics about tunneled Layer 2 PDUs on an interface. The statistics include:

Number of incoming Layer 2 PDUs
Number of outgoing Layer 2 PDUs
Number of dropped Layer 2 PDUs that exceed the configured drop threshold
The proceeding statistics serve as a reference for traffic statistics and fault diagnosis.

Precautions

When tunneling is enabled on an interface for more than one Layer 2 protocol, specifying protocol or user-defined-protocol in this command is recommended. Otherwise, the following problems may occur due to excessive output information:

The output information is repeatedly refreshed, and therefore it is difficult to locate your desired information.
The system fails to respond to other requests because it is busy searching information.

Example

The actual command output varies according to the device. The command output here is only an example.
