Using CE Ping to Monitor the Connectivity Between a PE and a CE on a VPLS Network

After you configure a virtual private LAN service (VPLS) network, use customer edge (CE) ping to monitor the connectivity between a provider edge (PE) and a CE on the VPLS network.

Prerequisites

The VPLS network has been correctly configured, and the specified virtual service instance (VSI) is Up.

Context

When you specify a source IP address, note the following:

The source IP address must be on the same network segment as the destination IP address. If they are on different network segments, the destination node considers Address Resolution Protocol (ARP) request packets invalid and does not return ARP response packets.
The specified source IP address must be unique on the L2VPN network. If the specified source IP address is the same as a used IP address, packets cannot be properly forwarded. As a result, user packets with the specified source IP address cannot be sent to the network. If the specified source IP address is the same as the gateway IP address, no users cannot access the network.

After you run the ce-ping command, the device displays a message to prompt to confirm that you have specified a unused IP address as the source IP address. Enter Y.

Procedure

Run the following command to monitor the connectivity between a PE and a CE:

ce-ping ip-address vsi vsi-name source-ip source-ip-address [ mac mac-address ] [ interval interval | count count ] ^*

For example:

<HUAWEI> ce-ping 10.1.1.1 vsi abc source-ip 10.1.1.2 mac 00e0-fc12-5678 interval 2 count 5
Info: If the designated source IP address is in use, it could cause the abnormal data transmission in VPLS network. Are you sure the source-ip is unused in this VPLS? [Y/N]:y
Ce-ping is in process...

10.1.1.1 is used by 00e0-fc12-3456
