SNMP traps can also be configured to provide an automated method of
fault notification. If the fault notification generator detects one or more
defects within the configured time period, and fault alarms are enabled, a
corresponding trap will be sent. No further fault alarms are sent until the
fault notification generator has been reset by the passage of a configured
time period without detecting any further faults. Upon receiving a fault
alarm, you should inspect the related SNMP objects for the reporting MEP,
diagnose the fault, correct it, and re-examine the MEP’s SNMP objects to
see whether the fault notification generator has been reset.
This chapter describes commands used to configure CFM.

Command Function Mode
Defining CFM Structures
ethernet cfm ais level Configures the maintenance level at which Alarm
Indication Signal information will be sent
GC
ethernet cfm ais ma Enables the MEPs within the specified MA to send
frames with AIS information
GC
ethernet cfm ais period Configures the interval at which AIS information is
sent
GC
ethernet cfm ais suppress
alarm
Suppresses AIS messages following the detection of
defect conditions GC
ethernet cfm domain Defines a CFM maintenance domain, sets the
authorized maintenance level, and enters CFM
configuration mode; also specifies the MIP creation
method for MAs within this domain
GC
ethernet cfm enable Enables CFM processing globally on the switch GC
ma index name vlan Creates a maintenance association within the current
maintenance domain, maps it to a customer service
instance, and sets the manner in which MIPs are
created for this service instance
CFM
ma index name-format Specifies the name format for the maintenance
association as IEEE 802.1ag character based, or ITU-T
SG13/SG15 Y.1731 defined ICC-based format
CFM
ethernet cfm mep Sets an interface as a domain boundary, defines it as
a maintenance end point (MEP), and sets direction of
the MEP in regard to sending and receiving CFM
messages
IC
ethernet cfm port-enable Enables CFM processing on an interface IC
clear ethernet cfm ais
mpid
Clears AIS defect information for the specified MEP PE
