Using Ping to Monitor Link Connectivity on an EVPN VPWS Network

A ping operation can be performed to check EVPN VPWS network connectivity.

Prerequisites

Before using the ping evpn vpws command to check EVPN VPWS network connectivity, ensure that the EVPN VPWS network has been correctly configured.

Context

After EVPN VPWS configurations are complete, perform the following operation in any view of the client.

Procedure

Check the EVPN VPWS network connectivity.
- When the tunnel type of the EVPN VPWS network is MPLS:
  Run the ping evpn vpws local-ce-id remote-ce-id [ vpn-instance evpn-name ] [ control-word ] [ -a source-ip | -c count | -exp exp-value | -m interval | -s packet-size | -t time-out | -r reply-mode | -tc tc ] ^* command to check the EVPN VPWS status and locate the fault.
  
  In cross-domain scenarios, the control-word keyword must be specified, and the -r 4 mode is recommended.
- When the tunnel type of the EVPN VPWS network is SRv6:
  Run the ping evpn vpws local-ce-id remote-ce-id [ vpn-instance evpn-name ] [ end-op endOp ] [ -a source-ip | -c count | -exp exp-value | -m interval | -s packet-size | -t time-out | -r reply-mode | -tc tc | -service-class classValue ] ^* command to check the EVPN VPWS status and locate the fault.
If the local service ID is not globally unique, the vpn-instance evpn-name parameter must be specified.

The following shows an example:

# Perform a ping operation on the EVPN VPWS network.
```
<HUAWEI> ping evpn vpws 1 2 -c 2
