Port Group Spanning Tree Settings - D-Link DES-3326 User Manual

DES-3326 Layer 3 Fast Ethernet Switch User's Guide
Hello Time:[ ] The Hello Time can be set from 1 to 10
seconds. This is the interval between two transmissions
of BPDU packets sent by the Root Bridge to tell all other
Switches that it is indeed the Root Bridge. If you set a
Hello Time for your Switch, and it is not the Root
Bridge, the set Hello Time will be used if and when your
Switch becomes the Root Bridge.
Note: The Hello Time cannot be longer than the Max. Age.
Otherwise, a configuration error will occur.
Forward Delay:[
to 30 seconds. This is the time any port on the Switch
spends in the listening state while moving from the
blocking state to the forwarding state.
Priority:[ ] A Priority for the switch can be set from
0 to 65535. 0 is equal to the highest Priority.
number is used in the voting process between switches
on the network to determine which switch will be the
root switch. A low number indicates a high priority, and
a high probability that this switch will be elected as the
root switch.
Note: Observe the following formulas when setting the
above parameters:
Max. Age ≤ 2 x (Forward Delay - 1 second)
Max. Age ≥ 2 x (Hello Time + 1 second)

Port Group Spanning Tree Settings

In addition to setting Spanning Tree parameters for use on the
switch level, the DES-3326 allows for the configuration of groups of
ports, each port-group of which will have its own spanning tree,
and will require some of its own configuration settings. An STP
