through the states of listening and learning at power up. If
properly configured, each port stabilizes to the forwarding or
blocking state.

for that port.

User-Changeable STA Parameters
The 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.
