Configuration Guide
Procedure
Step 1 Create a VLAN.
Run the vlan command to create a VLAN that is associated with the object managed by a
maintenance association (MA).
Each MA corresponds to one VLAN. The Ethernet CFM checks the connectivity for each MA.
Step 2 Configure a maintenance domain (MD).
An MD can be a network or a part of a network on which the Ethernet CFM is performed. All
the MDs are managed by a unified Internet service provider (ISP).
l Run the cfm md command to create an MD.
l Run the display cfm md command to query the configuration information about an MD.
Step 3 Configure an MA.
An MA is a part of an MD. An MD can be divided into one or more MAs. Each MA corresponds
to one VLAN. The Ethernet CFM checks the connectivity for each MA.
l Run the cfm ma command to create an MA and configure the parameters of the MA.
l Run the cfm ma mdindex/maindex vlan vlanid command to configure the VLAN associated
l Run the cfm ma mdindex/maindex meplist mepid command to configure the maintenance
l Run the display cfm ma command to query the configuration information about an MA.
Step 4 Configure an MEP.
An MEP is the end point of a maintenance channel. Ethernet OAM tests the link connectivity
by using the MEPs on the two ends of a maintenance channel.
Run the cfm mep command to create an MEP.
When configuring an MEP, note that the objects managed by the MEP are in two directions, namely, up and
down.
l Up refers to the direction facing packet forwarding at the device layer. That is, packets are forwarded through
l Down refers to the reverse direction of the up direction. That is, packets are directly forwarded through the
Step 5 Enable the local CFM function globally.
Run the cfm enable function to enable the local Ethernet CFM OAM function globally.
By default, the Ethernet CFM OAM function is disabled globally.
Step 6 Enable the remote CFM function globally.
Run the cfm remote-mep-detect enable function to enable the remote Ethernet CFM OAM
function globally.
By default, the remote Ethernet CFM OAM function is disabled globally.
