Forward Delay Before Ports Transition to Forwarding State

The forwarding delay timer specifies the length of time a spanning-tree protocol bridge port remains in the listening and learning states before transitioning to the forwarding state. Setting the interval too short could cause unnecessary spanning-tree reconvergence. Before changing this parameter, you should have a thorough understanding of spanning-tree protocols.

To configure the forwarding delay timer, include the following statement:

forward-delay seconds;

You can include this statement at the following hierarchy levels:

  • [edit protocols rstp]
  • [edit protocols mstp]
  • [edit protocols vstp vlan vlan-id]
  • [edit routing-instances routing-instance-name protocols rstp]
  • [edit routing-instances routing-instance-name protocols (mstp]
  • [edit routing-instances routing-instance-name protocols vstp vlan vlan-id]
