Services Overview
Following are the key configurations for the Ethernet Connectivity Fault
Management. The MD and the MA are configured at system level while MEP and
MIP are configured on SAPs and SDPs of specific service instances.
Configuration of MEP and MIP in v-VPLS and VPLS is detailed in
Management Points (MEPs/MIPs) for Ethernet CFM on
62
For VPLS and v-VPLS services:
CFM can be enabled or disabled on a SAP or SDP bindings basis.
Up and/or down MEP with a MEP-ID on a SAP and SDP binding for each MD level
can be configured, modified, or deleted. Each MEP is uniquely identified by the
MA-ID, MEP-ID tuple.
MEP creation on a SAP is allowed only for Ethernet ports (with null, q-tags, qinq
encapsulations).
MIP creation on a SAP and SDP binding for each MD level can be enabled and
disabled. MIP creation is automatic or manual when it is enabled. When MIP creation
is disabled for an MD level, the existing MIP is removed.
MIP creation is not supported on mesh SDP binding
For EPIPE service:
CFM can be enabled or disabled on a SDP binding basis.
Down MEP with an MEP-ID on a SDP binding for each MD level can be configured,
modified, or deleted. Each MEP is uniquely identified by the MA-ID, MEP-ID tuple.
MIP creation on a SDP binding for each MD level can be enabled and disabled. MIP
creation is automatic or manual when it is enabled. When MIP creation is disabled
for an MD level, the existing MIP is removed.
Up MEP on a SDP binding, Down MEP, Up MEP and MIP on a SAP are not
supported.
Maintenance Domain (MD):
An MD contains one or more MAs that have the same MD level. There can be
three types of domains: customer domain, provider domain, and operator domain.
Each domain can be an OAM MD and can have one or more MAs.
MD level is an important CFM concept. Eight MD levels (0-7) are defined in CFM.
Level 0 is the lowest level; Level 7 is the highest level.
Maintenance Association (MA):
A set of Maintenance End Points (MEPs) that have the same MA identifier (MAID)
and maintenance domain (MD) level within one service instance to verify the
integrity of the service.
MA Endpoint (MEP):
MEPs initiate and terminate CFM messages, and are the origination and
termination points of the CFM operations.
MD Intermediate Point (MIP):
MIPs receive CFM messages and respond to the originating MEP. A MIP never
initiates messages and does not expect any messages. MIPs respond to
loopback and link trace messages.
