Using CE Ping to Check the Connectivity Between a PE and a CE in an EVC Model

After configuring a Bridge Domain (BD), you can use CE ping to check the connectivity between a PE and a CE in an Ethernet Virtual Connection (EVC) model.

Prerequisites

The network has been correctly configured, and the specified BD is Up.

Context

An EVC model unifies the Layer 2 bearer service model and configuration model. In an EVC model, you can use CE ping to check the link reachability between a PE and a CE in a specified BD. For details about EVCs, see HUAWEI NetEngine 8000 F Series Feature Description-Local Area Network. For configuration details, see EVC Configuration.

When using CE ping to check the link reachability between a PE and a CE, you must specify a source IP address that meets the following conditions:

The source IP address must be on the same network segment as the CE's IP address. If they are on different network segments, the CE considers received CE Ping packets invalid and discards them.
The source IP address must be an unused IP address in the specified BD. If you specify a used IP address for the source IP address, CE Ping packets cannot be properly forwarded. As a result, the user using the source IP address cannot access the Internet. If you specify a gateway IP address for the source IP address, all users cannot access the Internet.

To avoid this problem, do not specify a used IP address as the source IP address.

Procedure

Run the ce-ping ip-address bd bd-id source-ip source-ip-address [ mac mac-address ] [ interval interval | count count ] ^* command in any view to check the link reachability between a PE and a CE.

Info: If the designated source IP address is in use, it could cause the abnormal data transmission in EVC network. Are you sure the source-ip is unused in this EVC? [Y/N]:y
