Module: DC-ISIS-MIB
OID (symbolic): DC-ISIS-MIB::isisCircT1TimerRunning
OID (numeric): 1.2.826.0.1.1578918.5.63.1.1.3.2.1.24
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-only
Description: Is the T1 timer running on this circuit?
This object is only valid on a circuit that is currently running the IS-IS protocol (isisCircExtDomain is 'false' and isisCircOperState is 'operStatusUp').
When set to 'true', this indicates that the local node is running starting or restarting node procedures.
What is isisCircT1TimerRunning?
Reports whether the RFC 3847 T1 restart timer is currently running on this circuit, meaning the local node is actively performing start or restart procedures; this object is only meaningful when the circuit is actually running IS-IS (isisCircExtDomain false and isisCircOperState up). An admin checks this when diagnosing why a circuit's adjacency is taking longer than expected to fully establish during a router restart.
