Link Trace Replies Field Descriptions

Use the data in the following table to use the Link Trace Result tab.

Name

Description

DomainIndex

Indicates the Maintenance Domain Index.

AssociationIndex

Indicates the Maintenance Association Index.

MepId

Indicates the Maintenance EndPoint ID.

SeqNumber

Indicates the transaction identifier/sequence number returned by a previous transmit linktrace message command, indicating which LTM response is going to be returned. The default is 0.

Hop

Indicates the number of hops away from the LTM initiator.

ReceiveOrder

Indicates the index value used to distinguish among multiple LTRs with the same LTR Transaction Identifier field value. This value is assigned sequentially from 1, in the order that the Linktrace Initiator received the LTRs.

Ttl

Indicates the TTL field value for a returned LTR.

DomainName

Indicates the Maintenance Domain Name.

AssociationName

Indicates the Maintenance Association Name.

Forwarded

Indicates if a LTM was forwarded by the responding MP, as returned in the FwdYes flag of the flags field.

TerminalMep

Displays a boolean value stating whether the forwarded LTM reached a MEP enclosing its MA, as returned in the Terminal MEP flag of the Flags field.

LastEgressIdentifier

Displays an octet field holding the Last Egress Identifier returned in the LTR Egress Identifier TLV of the LTR. The Last Egress Identifier identifies the MEP Linktrace Indicator that originated, or the Linktrace Responder that forwarded, the LTM to which this LTR is the response. This is the same value as the Egress Identifier TLV of that LTM.

NextEgressIdentifier

Displays an octet field holding the Next Egress Identifier returned in the LTR Egress Identifier TLV of the LTR. The Next Egress Identifier Identifies the Linktrace Responder that transmitted this LTR, and can forward the LTM to the next hop. This is the same value as the Egress Identifier TLV of the forwarded LTM, if any. If the FwdYes bit of the Flags field is false, the contents of this field are undefined, and the field is ignored by the receiver.

RelayAction

Indicates the value returned in the RelayAction field.

SrcMac

Displays the MAC address of the MP that responded to the LTM request for this LTR.

IngressAction

Displays the value returned in the IngressAction Field of the LTM. The value ingNoTlv indicates that no Reply Ingress TLV was returned in the LTM.

IngressMac

Displays the MAC address returned in the ingress MAC address field. If the rcCfmLtrReplyIngress object contains the value ingNoTlv(5), then the contents of this field are meaningless.

EgressAction

Displays the value returned in the Egress Action Field of the LTM. The value egrNoTlv(5) indicates that no Reply Egress TLV was returned in the LTM.

EgressMac

Displays the MAC address returned in the egress MAC address field. If the rcCfmLtrReplyEgress object contains the value egrNoTlv(5), then the contents of this field are meaningless.
