ECFM (Ethernet Connectivity Fault Management) CLI commands are categorized as follows:

Enable Commands

This section includes ECFM enable commands.

ethernet cfm cc enable

Command Objective:
This command enables the transmission of Continuity Check Messages (CCMs). The level and vlan identifies the Maintenance End Points (MEPs) to which the configuration applies.

The no form of the command disables the transmission of CCMs.

Note: For the transmission of CCMs by the Vlan unaware MEPs, vlan is not to be specified.

Syntax:

ethernet cfm cc enable {domain < domain-name > | level < a,b,c-d >} [service < service-name> | vlan < vlan-id/vfi-id > | service-instance < integer(256- 16777214) >]no ethernet cfm cc enable {domain < domain-name > | level < a,b,c-d >} [service < service-name > | vlan < vlan-id/vfi-id > | service-instance < integer(256-16777214) >]

Parameter Description:

domain< domain-name > - Sets the status of CCM transimisson for the specified Maintenance Domain name. This value is a string with maximum size as 43.
level< a,b,c-d > - Sets the status of CCM transimisson for the specified level at which the maintenance domain is defined. This value ranges from 0 to 7. Use comma as a separator to enter a list of levels. For example: 1,2,4-7
service < service-name > - Sets the status of CCM transimisson for the specified service name at which the maintenance domain is defined. This value is a string with maximum size as 43.

vlan < vlan-id/vfi-id > – Sets the status of CCM transimisson for the specified VLAN / VFI ID. This value ranges from 1 to 65535.

< vlan –id > – VLAN ID is a unique value that represents the specific VLAN. This value ranges from 1 to 4094.
< vfi-id > – VFI ID is a VLAN created in the system which contains Pseudo wires and Attachment Circuits as member ports. This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.
Notes:
The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or Filtering Database entries.
VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.
The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example if 100 VFIs are supported, the maximum number of VFI supported will be restricted to maximum number of VLANs + 100. An error message is displayed for any value beyond this range.
vlan-list – Sets the CCM parameters for the specified VLAN list. Use comma separator to enter the list of vlan ids. For example: 1,2,100-102

service-instance< integer(256-16777214) > - Sets the status of CCM transimisson for the specified service instance. This value ranges from 256 to 16777214.

inward - Specifies the direction of the MEP as inward (up MEP) on the bridge port.Up MEP sends Continuity Check Messages towards the MAC Relay Entity. By default, the MEP direction is outward (down MEP); down MEP sends Continuity Check Messages away from the MAC Relay Entity.
mpid < id (1-8191) > - Configures the MEP ID at which the maintenance domain is defined. This value is unique over a given Maintenance Entity, identifying a specific Maintenance Entity Group End Point. This value ranges from 1 to 8191.

< vlan –id > -VLAN ID is a unique value that represents the specific VLAN. This value ranges from 1 to 4094.
< vfi-id > - VFI ID is a VLAN created in the system which contains Pseudo wires and Attachment Circuits as member ports. This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.
Notes:
The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or Filtering Database entries.
VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.
The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example if 100 VFIs are supported, the maximum number of VFI supported will be restricted to maximum number of VLANs + 100. An error message is displayed for any value beyond this range.
On a particular interface, only one MEP can be configured at a particular level, VLAN ID and direction.

service-instance < integer (256-16777214) > - Configures the service instance identifier for which the MEP is defined. This is required only for the ISID aware MEP. This is applicable only for ports in PBB bridge mode. This value ranges from 256 to 16777214.
active - Sets the operational status of the MEP.

Mode:
Interface Configuration Mode (Physical)

Default:

Direction of MEP - outward
Operation status - inactive

Note: This command executes only if:

Domain is created at the same level as the MEP which is to be configured and Service is created within the domain.
If a Service (Maintenance Association) is to be associated with more than one Vlan-id, then its Primary VLAN ID is mapped to all the associated VLAN Ids with the command ethernet cfm associate vlan-id primary-vlan-id.
MA Mep List with MepId of the MEP is configured with the command mep crosscheck mpid. < Id > [vlan < vlan-id >]
For ISID, PIP should not be configured as an UP MEP, as this has no significance.

Example:

Your Product(config-if)# ethernet cfm mep domain domain1 mpid 20 vlan 10

The no form of the command deletes statically defined MEP from the Crosscheck List.

Syntax:
mep crosscheck mpid <id(1-8191)> [{service | vlan <vlan-id/vfi-id> | service-instance <integer(256-16777214)>}]

no mep crosscheck mpid <id(1-8191)> [{service | vlan <vlan-id/vfi-id> | service-instance <integer(256-16777214)>]

Parameter Description:

mpid < id(1-8191 )> - Specifies MEP indentifier which is an unique identifier over a given maintenance association, identifying a specific Maintenance End Point. This value ranges from 1 to 8191.

vlan < vlan-id/vfi-id > - Specifies the Primary VLAN ID of service (Maintenance Association) with which remote MEP must be associated. This value ranges from 1 to 65535.

< vlan –id > – VLAN ID is a unique value that represents the specific VLAN. This value ranges from 1 to 4094.
< vfi-id > – VFI ID is a VLAN created in the system which contains Pseudo wires and Attachment Circuits as member ports . This creates a logical LAN for the VPLS service. This value ranges from 4096 to 65535.
Notes:
The VLAN ID 4095 is reserved and may be used to indicate a wildcard match for the VID in management operations or Filtering Database entries.
VFI IDs 4096 and 4097 are reserved identifiers used in MPLS PW.
The theoretical maximum for the maximum number of VFI is 65535 but the actual number of VFI supported is a sizing constant. Based on this, the maximum number of VFI ID accepted in the management interface is restricted. For example if 100 VFIs are supported, the maximum number of VFI supported will be restricted to maximum number of VLANs + 100. An error message is displayed for any value beyond this range.

Your Product(config-ether-ecfm)# mep crosscheck mpid 20 vlan 10

service

Command Objective:
