Bridge Priority:
The lower the bridge priority value is, the higher the priority it has. Usually, the
switch with the highest bridge priority is the root. If you wish the
POEGEM12T2SFP to be the root bridge you will need to ensure that other
bridges on your network have a higher bridge priority than that of this switch. The
valid value is 0 – 61440.
Default: 32768
Hello Time:
The Hello Time is used to determine the periodic time to send normal BPDU
messages from the designated ports among all bridges on your network. It
determines how long a bridge should send this message to other bridges to tell
them I am alive. When the POEGEM12T2SFP is the root bridge of the network,
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 seconds.
Default: 2 seconds
