•
MD Level – Authorized maintenance level for this domain. (Range: 0-7)
•
MIP Creation Type – Specifies the CFM protocol’s creation method for maintenance
intermediate points (MIPs) in this domain:
•
Default – MIPs can be created for any maintenance association (MA) configured in this
domain on any bridge port through which the MA’s VID can pass.
•
Explicit – MIPs can be created for any MA configured in this domain only on bridge ports
through which the MA’s VID can pass, and only if a maintenance end point (MEP) is
created at some lower MA Level.
•
None – No MIP can be created for any MA configured in this domain.
Configuring Detailed Settings for a Maintenance Domain
•
MD Index – Domain index. (Range: 1-65535)
•
MEP Archive Hold Time – The time that data from a missing MEP is retained in the continuity
check message (CCM) database before being purged. (Range: 1-65535 minutes; Default: 100
