Purpose
Used to configure the parameters of an MEP.
Syntax
config cfm mep [mepname <string 32> | mepid <int 1-8191> md [<string 22> |
md_index <uint 1-4294967295>] ma [<string 22> | ma_index <uint 1-4294967295>]]
{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 MEPs Down: priority 3.
•
Some Remote MEP MAC Status Errors: priority 2.
•
Some Remote MEP Defect Indications: priority 1.
If multiple types of the fault occur on an MEP, only the fault with the highest priority will be
alarmed.
