Configuring MEPs
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. A MEP list is a collection of local MEPs that can be
configured in an MA and the remote MEPs to be monitored. You cannot create a MEP if the MEP ID
is not included in the MEP list of the service instance.
On the same level of an interface, you can configure an outward-facing MEP for only one MA with no
VLAN attribute.
Follow these guidelines when you configure MEPs:
• Configurations in Ethernet interface view take effect only on the current interface.
• Configurations in aggregate interface view take effect on the aggregate interface and all its
member ports.
• Configurations on a member port take effect only when the member port leaves the aggregation
group.
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 or Layer 2
aggregate interface view.
interface
interface-type
interface-number
N/A
4. Create a MEP.
• Create a MEP in Layer 2
Ethernet interface view or
Layer 2 aggregate interface
view:
cfd mep mep-id
service-instance
instance-id { inbound |
outbound }
By default, no MEP is configured.
Configuring MIP auto-generation rules
As functional entities in a service instance, MIPs respond to various CFD frames, such as LTM and
LBM frames. You can configure MIP auto-generation rules for the system to automatically create
MIPs.
Any of the following events can cause MIPs to be created or deleted after you have configured the
cfd mip-rule command:
• Enabling or disabling CFD.
• Creating or deleting MEPs on a port.
• Changes occur to the VLAN attribute of a port.
• The rule specified in the cfd mip-rule command changes.
An MA carrying no VLAN attribute is mainly used to detect direct link status. It cannot generate MIPs.
For an MA carrying VLAN attribute, if the same or higher level MEP exists on the interface, no MIP is
generated for the MA on the interface.
To configure the rules for generating MIPs:
