• Three MD levels, customer, carrier, and intra-carrier, can be configured, modified, or
deleted.
• The following MD name formats are supported:
→ None — no MD name
→ DNS name
→ MAC address and 2-octet integer
→ Character string
• MA with MA-ID for each MD level can be configured, modified, or deleted.
→ Each MA is uniquely identified by the MD level, short MA name tuple, which is the
MA-ID.
→ The following short MA name formats are supported:
− Primary VLAN ID (VID)
− Character string
− 2-octet integer
− RFC 2685, Virtual Private Networks Identifier
→ Note: When a VID is used as the short MA name, CFM will not support VLAN
translation because the MA-ID must match all the MEPs.
→ The default format for a short MA name is an integer. Integer value 0 means the MA
is not attached to a VID. This is useful for VPLS services on SR/ESS platforms
because the VID is locally significant.
• Up and/or down MEP with an MEP-ID on a SAP and SDP 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 for each MD level can be enabled and disabled. MIP
creation is automatic 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 bindings.
