Step Command Remarks
2. Create a service instance
without the MD name.
cfd service-instance instance-id
maid format { icc-based ma-name
| string ma-name } level level-value
vlan vlan-id
By default, no service instance is
created.
Configuring MEPs
IMPORTANT:
You cannot create a MEP if the MEP ID is not included in the MEP list of the service instance.
CFD is implemented through various operations on MEPs. As a MEP is configured on a service instance,
the MD level and VLAN attribute of the service instance become the attribute of the MEP.
Before creating MEPs, configure the MEP list first. An MEP list is a collection of local MEPs allowed to be
configured in an MA and the remote MEPs to be monitored.
To configure a MEP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a MEP list.
cfd meplist mep-list
service-instance instance-id By default, no MEP list is
configured.
3. Enter Layer 2 Ethernet
interface view. interface interface-type
interface-number
N/A
4. Create a MEP.
cfd mep mep-id service-instance
instance-id { inbound | outbound } By default, no MEP is configured.
5. Enable the MEP.
cfd mep service-instance
instance-id mep mep-id enable
By default, the MEP is disabled.
Configuring MIP generation rules
CAUTION:
Any of the following actions or cases can cause MIPs to be created or deleted after you have configured
the cfd mip-rule command:
• Enabling CFD (use the cfd enable command)
• Creating or deleting the MEPs on a port
• Changes occur to the VLAN attribute of a port
• The rule specified in the cfd mip-rule command changes
As functional entities in a service instance, MIPs respond to various CFD frames, such as LTM frames, LBM
frames, and TST frames. You can choose appropriate MIP generation rules based on your network
design.
To configure the rules for generating MIPs:
