restart-time (Fabric Control)


Hierarchy Level


Configure the duration of the graceful restart period for the fabric control Routing Engine.

The graceful restart resynchronization process takes longer when the QFabric system contains node groups that have a large number of VLANs. The graceful-restart duration should, therefore, be set higher when the QFabric system contains at least one node group with a large number of VLANs.

Configure a restart time of 600 seconds if the number of VLAN members (vmembers) exceeds 32k.


Configuring the restart time restarts the session between the fabric control Routing Engine and the Node groups. Traffic is dropped as a result of this restart. Normal QFabric system operations should resume once the session has restarted without any further user actions.

  • Default: 300 seconds
