Global Configuration
Command Usage
This command sets the maximum time (in seconds) the root device will wait
before changing states (that is, 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 a discarding state; otherwise,
temporary data loops might result.
Example
4.3.11.4 spanning-tree hello-time
Use this command to configure the spanning tree bridge hello time globally for this
switch. Use the no form to restore the default.
Syntax
spanning-tree hello-time time
no spanning-tree hello-time

The maximum value is the lower of 10 or [(max-age / 2) -1].
