ERPS Troubleshooting

If the configured ERPS loop cannot achieve the Ethernet loop switching protection,

check if it was wrong with the following reasons:

Check if the basic configuration is correct and check if the protection instance of

every node, control-vlan, wtr-timer, guard-timer and raps-mel are consistent.

Check if the vlan that user data flow is in is not the same one that control-vlan is in.

In the ERPS loop instance, control vlan is only used to transmit ERPS protocol
