C HAPTER 33 | Spanning Tree Commands
– 759 –
spanning-tree
forward-time
This command configures the spanning tree bridge forward time globally
for this switch. Use the no form to restore the default.
S YNTAX
spanning-tree forward-time seconds
no spanning-tree forward-time
seconds - Time in seconds. (Range: 4 - 30 seconds)
The minimum value is the higher of 4 or [(max-age / 2) + 1].
D EFAULT S ETTING
15 seconds
C OMMAND M ODE
Global Configuration
C OMMAND U SAGE
This command sets the maximum time (in seconds) the root device will
wait before changing states (i.e., discarding to learning to forwarding). This
delay is required because every device must receive information about
topology changes before it starts to forward frames. In addition, each port
needs time to listen for conflicting information that would make it return to
the discarding state; otherwise, temporary data loops might result.
E XAMPLE
Console(config)#spanning-tree forward-time 20
Console(config)#
spanning-tree hello-
time
This command configures the spanning tree bridge hello time globally for
this switch. Use the no form to restore the default.
S YNTAX
spanning-tree hello-time time
no spanning-tree hello-time
time - Time in seconds. (Range: 1-10 seconds).
The maximum value is the lower of 10 or [(max-age / 2) - 1].
D EFAULT S ETTING
2 seconds
C OMMAND M ODE
Global Configuration
C OMMAND U SAGE
This command sets the time interval (in seconds) at which the root device
transmits a configuration message.
