Purpose
Used to configure parameters of a MEP.
Syntax
config cfm mep [mepname <string 32> | mepid <int 1-8191> md <string 22> ma
<string 22>] {state [enable | disable] | ccm [enable | disable] | pdu_priority <int
0-7> | fault_alarm [all | mac_status | remote_ccm | error_ccm | xcon_ccm |
none] | alarm_time <centisecond 250 -1000> | alarm_reset_time <centisecond
250-1000>}
Description
An MEP may generate 5 types of Fault Alarms, as shown below by their priorities
from high to low:
Cross-connect CCM Received: priority 5
Error CCM Received: priority 4
Some Remote MEP Down: priority 3
Some Remote MEP MAC Status Error: priority 2
Some Remote MEP Defect Indication: priority 1
If multiple types of faults occurr on a MEP, only the fault of the highest priority will
be alarmed.
