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).
fec-address: traceroute fanout limit was reached
The traceroute fanout limit was reached.
Error: An error occurred
info
Raise the traceroute fanout limit parameter.
fec-address: source address ip-address is invalid
The traceroute utility is configured to use an invalid source address.
Error: An error occurred
error
Configure traceroute to use a valid source address.
fec-address: traceroute path limit was reached
The traceroute path limit was reached.
Error: An error occurred
info
Raise the traceroute path limit parameter.
fec-address: unable to send probe (error-message)
The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) could not send a traceroute probe packet.
Error: An error occurred
error
Contact your technical support representative.
fec-address: unable to open socket (error-message)
The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) could not open a socket to initiate a traceroute operation.
Error: An error occurred
error
Contact your technical support representative.
fec-address: unable to select socket (error-message)
The Multiprotocol Label Switching (MPLS) Operation, Administration, and Maintenance (OAM) process (mplsoamd) could not select a socket to initiate a traceroute operation.
Error: An error occurred
error
Contact your technical support representative.
fec-address: topology update interrupted traceroute
A traceroute operation was interrupted by a topology change.
Event: This message reports an event, not an error
info
Wait for the next scheduled traceroute operation.
fec-address: traceroute TTL limit was reached
The time-to-live (TTL) limit for the traceroute utility was reached.
Error: An error occurred
info
Raise the traceroute TTL limit parameter.
fec-address: traceroute encountered unreachable node
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.
Error: An error occurred
info
Contact your technical support representative.
