lportTrkStatus
Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::lportTrkStatus
OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.35
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The current state of the trunk. The btdefined state only applies to backup trunks.
What is lportTrkStatus?
This read-only field reports where the trunk protocol's state machine currently sits, from nattempt (attempting to establish) through n2way and nexchange, up to nfull (fully operational), with btdefined reserved specifically for backup trunks awaiting definition. An admin watching this during trunk bring-up can tell exactly which handshake stage is stuck if the trunk never reaches nfull. For example, a trunk stuck reporting nexchange(5) instead of progressing to nfull(7) points to a problem during the PVC or route exchange phase rather than basic link connectivity.
