MEP CCM LTM PRIORITY

mep ccm-ltm-priority

Overview Use this command to specify the queuing and p-bit priority for CCM messages.
mep ccm-ltm-priority <0-7>
Syntax
Default 7
Mode Interface Ethernet CFM MEP Configuration
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)#
awplus(config-if)#
MD-INST2 ma-name MA-INST2-1
awplus(config-if-eth-cfm-mep)#
CCMs should be the highest priority message so we recommend leaving their
priority as 7.
