Configuring Ethernet Connectivity Fault Management in a Service Provider Network
Purpose
Configures a maintenance association within a
maintenance domain and enters Ethernet connectivity
fault management (CFM) service configuration mode.
Configures the transmission of continuity check messages
(CCMs).
Configures the per-service parameters and sets the
interval at which CCMs are transmitted.
Returns to Ethernet connectivity fault management
configuration mode.
Sets the amount of time that data from a missing MEP
is kept in the continuity check database or that entries
are held in the error database before they are purged.
Returns to global configuration mode.
Enables CFM processing globally on the device.
Enables caching of CFM data learned through traceroute
messages.
Sets the maximum size for the CFM traceroute cache
table.
