Parameters:

Parameter Description
name MEG name. The name should include the ICC and UMC in a single string, as specified in Y.1731.

vce Indicate the VCE name from which to obtain the component ID, instead of entering the component parameter directly.
component Specify the ID of the component on which this Maintenance Association will be made.
vlan-type Specify the type of VLAN associated with this Maintenance Association. If the value "none" is specified, the association is not attached to any VLAN and the contents of the VLAN ID list are ignored. When a VCE is specified, the correct type is automatically selected.
vid-list A comma-separated list of VLAN ID values. If the VLAN ID list is left empty, the association is not attached to a VLAN and the VLAN type is set to "none" implicitly. If a vid-list is provided without specifying the vlan-type, it is set to C-VLAN implicitly.

rmep-auto-discovery Remote MEP auto-discovery. When enabled, remote MEPs will be automatically added to the MA/MEG when the remote MEP's CCM message is received.
maid-string-format-mode Controls the behavior of the generation of CCM PDUs using Character-String (2) format with MD Name not present (1). Valid values are:
  • normal: CCM PDUs using this format will result in the Short MA Name Length field having the correct value.
  • legacy: CCM PDUs generated using this format and whose Short MA Name length is less than 13, will result in the Short MA Name Length field having a fixed value of 13. When the Short MA Name length is 13 or greater, the generated CCM PDU will have the correct value in the Short MA Name Length field. This will enable inter-operability with existing Cisco equipment running older firmware versions and configured to use Character String format with MD Name not present.

cfm edit defaults

cfm edit defaults - Modify CFM default parameters

Description:

The MHF default parameters control the MHF creation for VIDs that are not attached to an MA within a VLAN component. For each component port, a VID is attached to an MA at a specific MD level, if at this level a MEP exists on that port or if an Up MEP exists on another port.

For a given VID, the default MHF MD level plus the set of Maintenance Associations that include that VID define the VID's active MD levels. The MD level at which MHFs could be created on a port for a given VID is the VID's lowest active MD level that is higher than any MEP configured on that port.

If at this level the VID is attached to an MA, the MA parameters control the MHF creation. If not, the MHF default parameters control the MHF creation.

Syntax:

cfm edit defaults {{vce <vce-name>} | {component <component-id>}}

  • none: No MHFs can be created.
  • default: Create MHFs if there is no lower active MD level or if there is a MEP at the next active MD level on the port.
  • explicit: Create MHFs only if there is a MEP at the next active MD level on the port.

cfm lbm

cfm lbm - Initiate a CFM loopback request

Description:

Initiate a CFM loopback request from a MEP. The MEP is specified by MEP index or by MEP name. The target address is identified by MAC address or by remote MEPID. When identifying the target by remote MEPID, the remote MEP MAC address should be resolved into the remote MEP database. Otherwise, an invalid state error will be returned.

If the parameters "rmep-id" and "dst-mac-addr" are omitted, a single multicast LBM is sent without Data TLV. The command waits five seconds for responses and displays the address of each responder. Otherwise, the loopback is initiated and the command completes immediately. In the latter case, if the parameter "data" or "data-length" is provided, the LBM includes a Data TLV. By default, there is no Data TLV. In both cases, the loopback request status is available from:

"cfm show mep status <mep-index>"

An active loopback request can be stopped using:
"cfm stop lbm"

Syntax:

cfm lbm {mep-idx <mep-index> | mep-name <name>}
          { {{rmep-id <1-8191>} |
             {dst-mac-addr <mac-addr>}} |

             {data <string>} |
             {data-length <1-1488>}}+

  <mep-index> = <decimal>
  <name>      = <string>

Parameters:

Parameter Description
mep-index Specifies the local MEP index from which the loopback request should be initiated.
mep-name Specifies the local MEP instance by name from which the loopback request should be initiated.
rmep-id Specifies a remote MEP for loopback target.
dst-mac-addr Specifies a MAC address for loopback target.
nbr-msg Specifies the amount of loopback messages (LBM) to send. Default value is 1 message.
Interval Specifies the interval between LBMs in milliseconds. Default value is 1000.
vlan-priority Specifies the VLAN priority of LBMs.
vlan-de Specifies the VLAN drop eligible indicator value of LBMs.
data Specifies a data pattern for LBM Data TLV. By default, the Data TLV is filled with incremental values.
data-length Specifies the data length of the LBM Data TLV. By default, the length of the data parameter value is used.

cfm ltm

cfm ltm - Initiate a CFM link trace request

Description:

Initiate a CFM link trace request from a MEP. The MEP is specified by MEP index or by MEP name. The target address is identified by MAC address or by remote MEPID. When identifying the target by remote MEPID, the remote MEP MAC address should be resolved into the remote MEP database. Otherwise, an invalid state error will be returned.

In verbose mode, the command waits a few seconds to display replies before completing. In non-verbose mode, the command completes immediately and returns a link trace transaction identifier. In both cases, the link trace transaction identifier allows displaying results from recent link traces using the "cfm show ltr" command.

Syntax:

cfm ltm {{mep-idx <mep-index> | mep-name <name>}
           {{rmep-id <1-8191>} |
           {dst-mac-addr <mac-addr>}} |

           {fdb-only <yes | no> } |
           {verbose <yes | no>} }+

  <mep-index> = <decimal>
  <name>      = <string>

Parameters:

Parameter Description
mep-idx Specifies the local MEP index from which the link trace request should be initiated.
mep-name Specifies the local MEP instance by name from which the link trace request should be initiated.
rmep-id Specifies a remote MEP for target for the link trace.
dst-mac-addr Specifies a MAC address for target for the link trace.
ttl Specifies the link trace time to live.
fdb-only Specifies whether or not the LTM should set the flag "UseFDBonly" (IEEE 802.1ag) or the flag "HWonly" (Y.1731).
verbose Allows verbose mode. Default is non-verbose.

cfm show default-maid-string-format-mode

Description:

Show default MAID string-based format mode value

Syntax:

cfm show default-maid-string-format-mode

cfm show defaults

cfm show defaults - Show CFM defaults parameters

Description:

The MHF default parameters control the MHF creation for VIDs that are not attached to a Maintenance Association within a VLAN component. For each component port, a VID is attached to an MA at a specific MD level, if at this level a MEP exists on that port or if an Up MEP exists on another port.

For a given VID, the default MHF MD level plus the set of Maintenance Associations that include that VID define the VID's active MD levels. The MD level at which MHFs could be created on a port for a given VID is the VID's lowest active MD level that is higher than any MEP configured on that port.

If at this level the VID is attached to an MA, the MA parameters control the MHF creation. Otherwise, the MHF default parameters control the MHF creation.

cfm show defaults [{vce <vce-name>} | {component <component-id>}]

Parameters:

Parameter Description
<vce-name> <string>
<component-id> <decimal>
