Configuring CFD Functions

Configuration Prerequisites
Before configuring CFD functions, you need to complete basic CFD configurations first.

Configuring CC on MEPs

After the CC function is configured, MEPs can send CCMs mutually to check the connectivity between
them.
Follow these steps to configure CC on a MEP:
To do...
Enter system view
Configure the interval field value in
the CCM messages sent by MEPs
Enter Ethernet interface view
Enable CCM sending on a MEP
The relationship between the interval field value in the CCM messages, the interval between CCM
messages and the timeout time of the remote MEP is illustrated in
Table 1-1 Relationship of the interval field value, the interval between CCM messages and the timeout
time of the remote MEP
The interval field value
3
4
5
6
7
On different devices, the MEPs belonging to the same MD and MA should be configured with the
same CCM sending interval.
If the interval field value in the CCM messages sent by MEPs is 3, configuring a large number of
MEPs in the same MD and MA may degrade the device performance.

Configuring LB on MEPs

The LB function can verify the link state between two ends after CC detects a link fault.
Use the command...
system-view
cfd cc interval interval-value
service-instance instance-id
interface interface-type
interface-number
cfd cc service-instance
instance-id mep mep-id enable
