Automatic connectivity detection on directly connected links
MDs are classified based on the ISP that manages the devices. All the devices that are
managed by a single ISP and enabled with CFM can be configured in an MD.
One default MD can be configured on each device, that it transmits high-level CCMs and
generates MIPs to reply LTR packets.
MAs are classified based on different SIs. An MA is associated with a VLAN. A VLAN
generally maps to an SI. When the MA is classified, fault detection in connectivity can be
carried out on the network where an SI is transmitted.
You need to determine the interfaces on which devices are located at the edge of the MA,
that is, to determine that MEPs must be configured on the interfaces on which devices.
The devices at both ends must be configured in the same MA within an MD.
An MA can be either associated with a VLAN or not.
MEPs must be configured on the interfaces at both ends of the directly connected link.
Data
Name and level of an MD
(Optional) Name and level of a default MD
Name of an MA, ID of the VLAN associated with the MA
ID of a MEP, name of the interface on which the MEP resides, type of the MEP
(Optional) ID of an RMEP and bridge MAC address of the device on which the RMEP
resides
Rule for creating a MIP
Interval for a MEP sending or detecting CCMs in an MA
(Optional) ID of the specified VLAN
