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 SNMP-24MGB as
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 SNMP-24MGB is 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. Default is 2 seconds.
Max. Age:
When the SNMP-24MGB is the root bridge, the whole LAN will apply this figure set
by this switch as their maximum age time. When a bridge received a BPDU
originated from the root bridge and if the message age conveyed in the BPDU
exceeds the Max. Age of the root bridge, the bridge will treat the root bridge
malfunctioned and issue a Topology Change Notification (TCN) BPDU to all other
bridges. All bridges in the LAN will re-calculate and determine who the root bridge
is. The valid value of Max. Age is 6 ~ 40 seconds. Default is 20 seconds.
