MPLS_OAM System Log Messages

This chapter describes messages with the MPLS_OAM prefix. They are generated by the Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd), which supports traceroute operations for LDP label-switched paths (LSPs).

MPLS_OAM_FANOUT_LIMIT_REACHED

System Log Message

fec-address: traceroute fanout limit was reached

Description

The traceroute fanout limit was reached.

Type

Error: An error occurred

Severity

info

Facility

LOG_DAEMON

Action

Raise the traceroute fanout limit parameter.

MPLS_OAM_INVALID_SOURCE_ADDRESS

System Log Message

fec-address: source address ip-address is invalid

Description

The traceroute utility is configured to use an invalid source address.

Type

Error: An error occurred

Severity

error

Facility

LOG_DAEMON

Action

Configure traceroute to use a valid source address.

MPLS_OAM_PATH_LIMIT_REACHED

System Log Message

fec-address: traceroute path limit was reached

Description

The traceroute path limit was reached.

Type

Error: An error occurred

Severity

info

Facility

LOG_DAEMON

Action

Raise the traceroute path limit parameter.

MPLS_OAM_SEND_FAILED

System Log Message

fec-address: unable to send probe (error-message)

Description

The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) could not send a traceroute probe packet.

Type

Error: An error occurred

Severity

error

Facility

LOG_DAEMON

Action

Contact your technical support representative.

MPLS_OAM_SOCKET_OPEN_FAILED

System Log Message

fec-address: unable to open socket (error-message)

Description

The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) could not open a socket to initiate a traceroute operation.

Type

Error: An error occurred

Severity

error

Facility

LOG_DAEMON

Action

Contact your technical support representative.

MPLS_OAM_SOCKET_SELECT_FAILED

System Log Message

fec-address: unable to select socket (error-message)

Description

The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) could not select a socket to initiate a traceroute operation.

Type

Error: An error occurred

Severity

error

Facility

LOG_DAEMON

Action

Contact your technical support representative.

MPLS_OAM_TRACEROUTE_INTERRUPTED

System Log Message

fec-address: topology update interrupted traceroute

Description

A traceroute operation was interrupted by a topology change.

Type

Event: This message reports an event, not an error

Severity

info

Facility

LOG_DAEMON

Action

Wait for the next scheduled traceroute operation.

MPLS_OAM_TTL_EXPIRED

System Log Message

fec-address: traceroute TTL limit was reached

Description

The time-to-live (TTL) limit for the traceroute utility was reached.

Type

Error: An error occurred

Severity

info

Facility

LOG_DAEMON

Action

Raise the traceroute TTL limit parameter.

MPLS_OAM_UNREACHABLE

System Log Message

fec-address: traceroute encountered unreachable node

Description

The traceroute utility encountered a node that does not have a computable destination address. The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) therefore could not send a probe to the node.

Type

Error: An error occurred

Severity

info

Facility

LOG_DAEMON

Action
