Parameter description:
Spanning Tree Protocol:
Set 802.1W Rapid STP function Enable / Disable. Default is “Disable”
Bridge Priority:
The lower the bridge priority is, the higher priority it has. Usually, the
bridge with the highest bridge priority is the root. If you want to have the
FGP-2472as root bridge, you can set this value lower than that of bridge
in the LAN. The valid value is 0 ~ 61440. The default is 32768.
Hello Time:
Hello Time is used to determine the periodic time to send normal BPDU
from designated ports among bridges. It decides how long a bridge
should send this message to other bridge to tell I am alive. When the
FGP-2472is the root bridge of the LAN, for example, all other bridges will
use the hello time assigned by this switch to communicate with each
other. The valid value is 1 ~ 10 in unit of second.
