Configuration Task Summary

Configuration Task Summary

After basic CFM functions are configured, CFM can work properly. To deploy special CFM functions such as loopback, linktrace, adjusting CFM parameters, and CFM association, perform the configurations according to the following sections.

Table 9-8 describes the CFM configuration tasks.

Table 9-8  CFM configuration task summary




Configure basic CFM functions

CFM detects connectivity faults on an end-to-end link.

Configuring Basic Ethernet CFM Functions

Configure loopback

Similar to IP ping, loopback monitors connectivity of a path between a MEP and an RMEP.

Configuring Loopback

Configure linktrace

Linktrace sends test packets and waits for a response to check whether the destination device is reachable.

Configuring Linktrace

Set CFM parameters

By adjusting Ethernet CFM parameters, you can better implement end-to-end connectivity fault detection on the Ethernet.

Setting CFM Parameters

Configure CFM association

CFM can be associated with interfaces and detection protocols to quickly report link faults, ensuring service reliability.

Configuring CFM Association
