spanning-tree forward-delay
Use the spanning-tree forward-delay redundancy configuration command on the switch to set the
forward-delay time for the spanning-tree. The forwarding time specifies how long each of the listening and
learning states last before the interface begins forwarding. Use the no form of this command to return to the
default setting.
Commands
spanning-tree forward-delay seconds
no spanning-tree forward-delay
Syntax
Description
spanning-tree Configure spanning tree
forward-delay Configure spanning tree BPDU forward delay
seconds Range from 4 to 30 seconds
Defaults Forward delay = 15 sec.
Command
Modes
Redundancy configuration
Usage
Guidelines
2*( hello-time + 1.0 sec) <= max-age <= 2*( forward-delay - 1.0 sec)
Examples
PT-7828(config-rdnt)# spanning-tree forward-delay
<UINT:seconds> - Range from 4 to 30 seconds
Error
messages
The BPDU forward delay time must be in the range from 4 to 30 sec.
The formula must be obeyed:
2 x (Hello Time + 1 sec) <= Max age <= 2 x (Forward Delay - 1 sec)
