Good to know Dave.
It depends on the diameter though. Diameter of 3 gives Fwdelay=5;
SW2(config)#spanning-tree vlan 1 root primary diameter 3 hello-time 1
SW2(config)#
SW2#sh spanning-tree vlan 1 | i VLAN|ID|Forward
VLAN0001
Root ID Priority 24577
Hello Time 1 sec Max Age 7 sec Forward Delay 5 sec
Bridge ID Priority 24577 (priority 24576 sys-id-ext 1)
Hello Time 1 sec Max Age 7 sec Forward Delay 5 sec
While diameter of 6 gives Fwdelay=8;
SW2(config)#spanning-tree vlan 1 root primary diameter 6 hello-time 1
SW2(config)#
SW2#sh spanning-tree vlan 1 | i VLAN|ID|Forward
VLAN0001
Root ID Priority 24577
Hello Time 1 sec Max Age 11 sec Forward Delay 8 sec
Bridge ID Priority 24577 (priority 24576 sys-id-ext 1)
Hello Time 1 sec Max Age 11 sec Forward Delay 8 sec

RE: Spanning-Tree
There is yet another way to do this (if something in the scenario won't
let you directly use that forward-time command)......
You can use the extensions on this command:
spanning-tree vlan xx root <primary/secondary> diameter hello-time
Setting the hello-time to 1 sec will automatically add the commands for
the forward-time of 5seconds and a max-age time of 7 seconds. (either
primary or secondary both work).
Just another way to do something.

Hi Tony,
When they ask you to set the time fixed to 5 seconds. It's more likely
to
adjust the forwarding time;

wstp.

Configure the forward time of a VLAN. The forward delay is the number of
seconds a port waits before changing from its spanning-tree learning and
listening states to the forwarding state.
SW2(config)#spanning-tree vlan 1 forward-time 5
SW2#sh spanning-tree vlan 1 | i VLAN|ID|Forward
VLAN0001
Root ID Priority 24577
Hello Time 2 sec Max Age 20 sec Forward Delay 5 sec
Bridge ID Priority 24577 (priority 24576 sys-id-ext 1)
Hello Time 2 sec Max Age 20 sec Forward Delay 5 sec
