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
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
