This read-only value reports the state of this SMDS circuit, giving the overall connection status for the SMDS route entry, analogous in purpose to cktLeafVcState but for SMDS rather than the more detailed multipoint leaf state machine. Since the syntax is plain INTEGER without named enumeration values documented in this excerpt, the actual state values likely require cross-referencing the MIB's full definition or vendor documentation to interpret numerically. An engineer polling this object during SMDS circuit troubleshooting would need to map the returned integer against the switch vendor's SMDS state table to determine whether the circuit is up, retrying, or failed.
