Configure Layer 2 IP Ping

Before you begin

  • On the source and destination nodes, you must configure a CFM MD, MA, and MEP, and assign a nodal MEP to the B-VLAN.

  • If you want to run a Layer 2 IP Ping for a specific VRF, you must use EDM in the specific VRF context first. For more information, see the procedure for selecting and launching a VRF context view in Select and Launch a VRF Context View.

About this task

Use this procedure to configure Layer 2 IP ping

Procedure

  1. In the navigation pane, expand Configuration > Serviceability > Diagnostics.
  2. Select L2Ping/L2Trace Route.
  3. Select the L2 IP Ping tab.
  4. To add a new entry:
    1. Select Insert.
    2. Specify the destination IP address.
    3. Select Insert.
  5. To start the Layer 2 IP ping, highlight an entry, and then select Start.
  6. To stop the Layer 2 IP ping, select Stop.
  7. To update the Layer 2 IP ping, select Refresh.

L2 IP Ping Field Descriptions

Use the data in the following table to use the L2 IP Ping tab.

Name

Description

IpAddrType

Specifies the address type of destination IP Address (only IPv4 is supported).

IpAddr

Specifies the destination IP Address.

VrfId

Specifies the VRF ID.

VrfName

Specifies the name of the virtual router.

Messages

Specifies the number of L2IpPing messages to be transmitted per MAC/VLAN pair. Range is 1–200. The default is 1.

Status

Specifies the status of the transmit loopback service:

  • ready: the service is available.

  • transmit: the service is transmitting, or about to transmit, the L2IpPing messages.

  • abort: the service is aborted or about to abort the L2IpPing messages.

This field is also used to avoid concurrency or race condition problems that could occur if two or more management entities try to use the service at the same time.

The default is ready.

ResultOk

Indicates the result of the operation:

  • true: L2IpPing Messages will be or have been sent.

  • false: L2IpPing Messages will not be sent.

The default is true.

TimeoutInt

Specifies the interval to wait for an L2IpPing time-out with a range of 1–10 seconds with a default value of 3 seconds.

TestPattern

Specifies the test pattern to use in the L2IPPing PDU:

  • allZero — null signal without cyclic redundancy check

  • allZeroCrc — null signal with cyclic redundancy check with 32-bit polynomial

  • pseudoRandomBitSequence — pseudo-random-bit-sequence without cyclic redundancy check

  • pseudoRandomBitSequenceCrc — pseudo-random-bit-sequence with cyclic redundancy check with 32-bit polynomial.

A cyclic redundancy check is a code that detects errors.

The default value is allZero.

DataSize

Specifies an arbitrary amount of data to be included in the data TLV, if the data size is selected to be sent. The range is 0–400. The default is 0.

PathsFound

Specifies the number of paths found to execute the command. The default is 0.
