<

The
Max. Age
can be set from 6 to 40 seconds. At the end of the Max. Age,
if a BPDU has still not been received from the Root Bridge, your Switch will
start sending its own BPDU to all other Switches for permission to become
the Root Bridge. If it turns out that your Switch has the lowest Bridge
Identifier, it will become the Root Bridge.
Bridge Hello Time: (1
- 10 sec)
<
2
>
The Hello Time can be set from 1 to 10 seconds. This is the interval between
two transmissions of BPDU packets sent by the Root Bridge to tell all other
Switches that it is indeed the Root Bridge.
