RSTP Mode
: You must first enable STP/RSTP mode before configuring any related
parameters. Parameter settings required for both STP and RSTP are the same. Note that
802.1d refers to STP mode, while 802.1w refers to faster RSTP mode.
Bridge Configuration
Priority (0-61440)
: RSTP uses bridge ID to determine the root bridge, the bridge with the
highest bridge ID becomes the root bridge. The bridge ID is composed of bridge priority and
bridge MAC address. So that the bridge with the highest priority becomes the highest bridge
ID. If all of the bridge IDs have the same priority, the bridge with the lowest MAC address will
then become the root bridge.
Note
: The bridge priority value must be in multiples of 4096. A device with a lower number has
a higher bridge priority. Ex: 4096 is higher than 32768.
Max Age (6-40)
: Enter a value from 6 to 40 seconds here. This value represents the time that
a bridge will wait without receiving Spanning Tree Protocol configuration messages before
attempting to reconfigure.
If
JetNet 3706 / JetNet 3706f
is not the root bridge, and if it has not received a hello message
from the root bridge in the amount of time equal to the Max Age, then
JetNet 3706 / JetNet
3706f
will reconfigure itself as a root bridge. Once two or more devices on the network are
recognized as a root bridge, the devices will renegotiate to set up a new spanning tree
topology.
Hello Time (1-10)
: Enter a value from 1 to 10 seconds here. This is a periodic timer that drives
JetNet 3706/JetNet 3706f Industrial Web Managed PoE Plus Switch
