Command Usage
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.
Example
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.
Syntax

time
