isisCircExtendedCircID

Module: DC-ISIS-MIB

OID (symbolic): DC-ISIS-MIB::isisCircExtendedCircID

OID (numeric): 1.2.826.0.1.1578918.5.63.1.1.3.2.1.15

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: The value to be used as the extended circuit ID in 3Way handshake. This value is only used if isisCirc3WayEnabled is true, and must be unique across all circuits on this IS.

DC-ISIS uses the value for isisCircIndex as the extended circuit ID, and so this object is read-only.

What is isisCircExtendedCircID?

Reports the 4-byte Extended Circuit ID this router uses in 3-way handshake negotiation on this circuit, required to be unique across all circuits on this IS when isisCirc3WayEnabled is true; it is read-only because DC-ISIS simply reuses isisCircIndex as this value rather than letting it be independently configured. An admin reads this when comparing extended circuit IDs across routers while troubleshooting a 3-way handshake mismatch.
