Usage Guidelines

Usage Scenario

No specific multicast MAC address is defined in IEEE 802.1ag/Draft 7.0, so devices of different vendors may send CCMs with different multicast MAC addresses. To allow devices of different vendors to interconnect, you must use the same multicast MAC address on these devices. Otherwise, CCMs cannot be transmitted between these devices.

Prerequisites

The cfm enable command has been run to enable CFM globally.
The cfm version draft7 command has been run to switch the Ethernet CFM version to IEEE 802.1ag Draft 7.

Example

# Set the destination MAC address of a CCM to 0180-C210-FFF0.
