config cfm mep
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 <centiseconds 250 -1000> | alarm_reset_time <centiseconds 250-1000>}(1)
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.
Parameters mepname – Specifies the MEP name. It’s unique among all MEPs configured on the device.
mepid – Specifies the MEP MEPID. It should be configured in MA’s MEPID list.
md – Specifies the maintenance domain name.
ma – Specifies the maintenance association name.
state – Specifies the MEP administrative state.
enable – MEP is enabled.
disable – MEP is disabled. This is the default value.
ccm – Specifies the CCM transmission state.
enable – CCM transmission enabled.
disable – CCM transmission disabled. This is the default value.
pdu_priority – Specifies the 802.1p priority to be set in CCMs and LTMs messages
transmitted by the MEP. The default value is 7.
fault_alarm – Control types of fault alarms sent by the MEP.
all – Specifies that all types of fault alarms will be sent.
mac_status – Only Fault Alarms whose priority is equal to or higher than “Some Remote
MEP MAC Status Error” will be sent.
remote_ccm – Only Fault Alarms whose priority is equal to or higher than “Some Remote
MEP Down” will be sent.
error_ccm – Only Fault Alarms whose priority is equal to or higher than “Error CCM
Received” will be sent.
xcon_ccm – Only Fault Alarms whose priority is equal to or higher than “Cross-connect CCM
Received” will be sent.
none – No fault alarm is sent. This is the default value.
alarm_time – The time that a defect must last before the fault alarm can be sent. The default
value is 2 seconds.
alarm_reset_time – The timer must be clear of any alarm defects before the fault can be re-
