Ethernet Connectivity Fault Management (ETH-CFM)
Page 76 7210 SAS M Services Guide
• CFM can be enabled or disabled on a SAP or SDP bindings basis.
• The eight ETH-CFM levels are suggested to be broken up numerically between customer
7-5, service provider 4-3 and Operator 2-1. Level 0 is meant to monitor direct connections
without any MIPs and should be reserved for port-based facility MEPs. These can be
configured, deleted or modified.
• Down MEP and UP MEP with an MEP-ID on a SAP 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 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.
→ Only ingress MIPs are supported
→ MIP creation is not supported on mesh SDP bindings.
