User-Changeable STA Parameters
The Switch’s factory default setting should cover the majority of installations.
However, it is advisable to keep the default settings as set at the factory; unless, it is
absolutely necessary. The user changeable parameters in the Switch are as follows:
Priority – A Priority for the switch can be set from 0 to 65535. 0 is equal to the highest
Priority.
Hello Time – The Hello Time can be 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. If you set a Hello Time for your Switch, and it is not
the Root Bridge, the set Hello Time will be used if and when your Switch becomes the
Root Bridge.
