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 3706 / JetNet 3706f
will wait before checking to see if it
should be changed to a different state.
Once you have completed your configuration, click on
Apply
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
Apply
to save your settings.
