Protocol Description

The administrator, while configuring Maintenance Domains, defines certain DSAP s (Domain Service Access Point) to be directly accessed by the customer. Configuring Maintenance End Point on the defined DSAPs with the same MAID and MD Level, establis...

A Maintenance Domain ( MD ) is the network or the part of the network for which faults in connectivity are managed. A domain is owned and operated by a single entity and defined by a set of ports internal to it and at its boundary. Maintenanc...

The following are Maintenance Intermediate Point Half Function ( MHF ) features: Validates the received PDUs; Validates the received CCM PDUs, and builds the MIP CCM Database; Responds to LBM PDUs with LBR PDUs; Responds to LTM PDUs by for...

The articles in this subcategory describe ECFM and provide an overview of its salient features, such as MD (Maintenance Domain), MA (Maintenance Association), Maintenance Point, and CFM (Connectivity Fault Management) messages. ECFM provides capab...

Maintenance End Point ( MEP ) is capable of initiating and terminating OAM frames for fault management and performance monitoring. The following are the MEP functions: Periodically transmits multicast or unicast CCMs; Transmits LBM, LTM, TST...

Fault Management can proactively monitor the network for faults and notify the administrator so that timely action can be taken to ensure the availability of the network. Fault management includes: Fault detection Fault verification F...

A maintenance point is a demarcation point on an interface (port) that participates in CFM within a maintenance domain. Maintenance points on device ports act as filters that confine CFM frames within the bounds of a domain by dropping frames that d...

When relating to Ethernet Client Signal Failure ( ETH-CSF ), the following should be considered: ETH-CSF Considerations ETH-CSF is used by an ECFM MEP entity to propagate to a peer MEP Entity the detection of a failure or defect event in an Et...
