14. CFM
This section lets you set CFM (Connectivity Fault Management) Global, Service, and Domain parameters.
CFM is an IEEE standard that defines protocols and practices for OAM (Operations, Administration, and
Maintenance) for paths through 802.1 bridges and LANs. It is an amendment to IEEE 802.1Q-2005 and was
approved in 2007. IEEE 802.1ag is copied from the earlier ITU-T Recommendation Y.1731, which additionally
addresses performance monitoring.
The standard
1
) defines maintenance domains, their constituent maintenance points, and the managed objects
required to create and administer them.
2
) defines the relationship between maintenance domains and the
services offered by VLAN-aware bridges and provider bridges.
3
) describes the protocols and procedures used by
maintenance points to maintain and diagnose connectivity faults within a maintenance domain.
4
) provides
means for future expansion of the capabilities of maintenance points and their protocols.

Parameter descriptions
:
Sender Id TLV
: Choose whether and what to use as Sender ID TLVs in CCMs generated by this switch. This
parameter can be overridden by Domain and Service level configuration.
None
: Do not include Sender ID TLVs.
Chassis
: Enable Sender ID TLV and send Chassis ID (MAC Address).
Manage
: Enable Sender ID TLV and send Management address (IPv4 Address).
ChassisManage
: Enable Sender ID TLV and send both Chassis ID (MAC Address) and Management
Address (IPv4 Address).
Defer
: Let the Domain configuration decide if Sender ID TLVs will be included.
