Module: DC-ISIS-MIB
OID (symbolic): DC-ISIS-MIB::isisCircLevelIDOctet
OID (numeric): 1.2.826.0.1.1578918.5.63.1.1.4.1.1.5

Description: A one byte identifier for the circuit selected by the Intermediate System.
On point-to-point circuits, the value is used as the Local Circuit ID in point-to-point IIH PDUs transmitted on this circuit. In this case, values of isisCircLevelIDOctet do not need to be unique.
For broadcast circuits, the value is used to generate the LAN ID that will be used if this Intermediate System is elected as the Designated IS on this circuit. The value is required to differ on LANs where the Intermediate System is the Designated Intermediate System.
What is isisCircLevelIDOctet?
Reports the single-byte circuit identifier this router has chosen for this circuit at this level: on point-to-point circuits it's used as the Local Circuit ID in IIH PDUs (and need not be unique across circuits), while on broadcast circuits it's used to build the LAN ID this router would use if elected Designated IS — in that case it must differ across LANs where this router is the DIS. An admin cross-references this value when matching up circuit identifiers seen in captured IS-IS PDUs with the local circuit table.
