JetNet 4706/4706f Industrial Managed PoE Switch
49
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 4706/4706f
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 4706/4706f
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
the switch to send out a BPDU (Bridge Protocol Data Unit) packet to check current STP status.
The root bridge of the spanning tree topology periodically sends out a “hello” message to other
devices on the network to check if the topology is “healthy.” The “hello time” is the amount of time
the root has waited in between sending hello messages.
Forward Delay Time (4-30):
Enter a value between 4 and 30 seconds. This value is the time that
a port waits before changing from Spanning Tree Protocol learning and listening states to
forwarding state.
This is the amount of time
JetNet 4706/4706f
will wait before checking to see if it should be
changed to a different state.
Once you have completed your configuration, click the
Apply
button to apply your settings.
Note:
You must observe the following rules to configure Hello Time, Forwarding Delay, and Max
Age parameters.
2 × (Forward Delay Time – 1 sec) >= Max Age Time >= 2 × (Hello Time value + 1 sec)
Port Configuration
Select the port you want to configure; you will be able to view the current settings and status of
the port.
Path Cost:
Enter a number between 1 and 200,000,000. This value represents the “cost” of the
path to the other bridge from the transmitting bridge at the specified port.
Priority:
Enter a value between 0 and 240 using multiples of 16. This is the value that decides
which port should be blocked by priority in a LAN.
Admin P2P:
Some of the rapid state transitions that are possible within RSTP depend upon
whether the port of concern can only be connected to another bridge (i.e. it is served by a
point-to-point LAN segment), or if it can be connected to two or more bridges (i.e. it is served by a
shared-medium LAN segment). This function allows P2P status of the link to be manipulated
administratively.
Auto
means to auto select P2P or Share mode.
P2P
means P2P is enabled,
while
Share
means P2P is disabled.
Admin Edge:
A port directly connected to the end stations cannot create a bridging loop in the
network. To configure this port as an edge port, set the port to the
Enable
state. When the
non-bridge device connects an admin edge port, this port will be in blocking state and turn to
forwarding state in 4 seconds.
Once you have finished your configuration, click the
Apply
buttonto save your settings.
