Default

Mode

Usage
Maintenance Points are entities that exist within an MD/MA and can perform the
CFM/802.1ag functions such as Continuity Checks for fault management. The main
type of MP is a Maintenance End Point (MEP). This type of maintenance point sits
at the edges of a Maintenance Domain but is a member of only one MA within the
Maintenance Domain. Thus an MEP is used at the end of a VLAN segment, or it is
used at the end of a link.
A Local MEP can detect defects in connectivity of a VLAN or a local link using
Continuity Check Messages (CCM) by sending and receiving CCMs with Remote
MEP peers. CCMs are high priority messages by default, but the priority is
configurable, although we do not recommend changing it. Any defects detected
locally can also be conveyed to Remote MEP peers by sending a Remote Defect
Indicator (RDI) to the peers within a Continuity Check Message (CCM). If defects
persist long enough, an alarm can be generated.
Example
To set the queuing and p-bit priority for CCM messages to 6, use the commands:
awplus(config)#
interface port1.0.2
awplus(config-if)#
ethernet cfm mep down mpid 12 domain-name
MD-INST2 ma-name MA-INST2-1
awplus(config-if-eth-cfm-mep)#
mep ccm-ltm-priority 6
CCMs should be the highest priority message so we recommend leaving their
priority as 7.
