Module: PRVT-MPLS-LDP-MIB

OID (symbolic): PRVT-MPLS-LDP-MIB::mplsLdpSessionStatsUnknownMesTypeErrors

Description: This object counts the number of Unknown Message Type Errors detected by this LSR/LER during this session.

Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of mplsLdpSessionDiscontinuityTime.

What is mplsLdpSessionStatsUnknownMesTypeErrors?

Counts Unknown Message Type errors this LSR detected during this session, meaning it received an LDP message whose type code it did not recognize. Because unrecognized message types without the U bit set are simply logged here rather than tearing down the session, a rising count usually points to a version or vendor-extension mismatch with the peer rather than an active failure.

Examples
