Usage Guidelines
Usage Scenario
After the cfm trigger vlan mac-renew command is run, CFM deletes MAC address entries of a range of configured VLANs when detecting a fault so that services can be switched between links.
Precautions
A maximum of 10 VLAN ranges can be configured. The VLAN ranges cannot overlap.
When CFM detects a fault in a VLAN associated with the MA in the range specified in this command, the MAC address entries of this VLAN are deleted. If a fault is detected in a VLAN out of the specified range, the MAC address entries of this VLAN are not deleted.
If the cfm trigger vlan mac-renew command is run multiple times, MAC addresses of VLANs specified by the commands are deleted.
