Procedure 16-4.10: Enable AIS generation on a MEP
Overview
Use this procedure to activate AIS generation on a MEP.
When an impairment is detected, the MEP sends AIS frames (immediately and then at 1 minute intervals) at the client MD level in the forward direction so that downstream MEPs that would also detect the fault can suppress their alarms.
AIS insertion may be enabled on any MEP except, in R6.0, on a port which has spanning tree or ERP enabled. The insertion takes place into a configured client MD level, in the direction opposite of other MEP OAM transmission.

Enter the parameters as required. See AIS generation parameters. Click Submit to execute the command. Click Delete to remove the AIS Generation from the selected MEP ID. End of steps |
AIS generation parameters
|
Parameter |
Description |
CLI command |
|---|---|---|
|
MD Name |
The MD name of the selected MEP |
ethoam ais md <MDname> |
|
MA Name |
The MA name of the selected MEP. This is a drop-down list containing all MAs in the above selected MD. |
ethoam ais ma <MAname> |
|
SourceMEPID / Create |
The selected MEP ID. This is a drop-down list containing all MEPs in the above selected MD/MA. |
ethoam ais mep <sourceMEPID> |
|
Priority |
The priority of the AIS frames. Valid values: an integer in the range of 0 to 7. |
ethoam ais priority <priority-value> |
|
Client Level |
MD level for the generated AIS frames. Typically this is the next highest configured MD level, except for a Down-MEP on a customer port where it is typically a configured Customer MD level. Valid values: an integer in the range of 0 to 7. |
ethoam ais level <clientMDlevel> |
|
Maint CVLAN |
The VLAN ID of a maintenance CVLAN. The valid values: an integer in the range of 0 to 4094. The default value is 0 which means the AIS frames are untagged. This is an optional field. |
ethoam ais mnt-vlan <vid> |
