User-Changeable STA Parameters
The Switch’s factory default setting should cover the majority of installations. However,
it is advisable to keep the default settings as set at the factory; unless, it is absolutely
necessary. The user changeable parameters in the Switch are as follows:
Priority – A Priority for the switch can be set from 0 to 65535. 0 is equal to the highest
Priority.
Hello Time – The Hello Time can be 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.
NOTICE:
The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration
error will occur.
Max. Age – The Max Age can be from 6 to 40 seconds. At the end of the Max Age, if a
BPDU has still not been received from the Root Bridge, your Switch will start sending
its own BPDU to all other Switches for permission to become the Root Bridge. If it
turns out that your Switch has the lowest Bridge Identifier, it will become the Root
Bridge.
Forward Delay Timer – The Forward Delay can be from 4 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.
NOTICE:
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 Priority – A Port Priority can be from 0 to 255. The lower the number, the greater
the probability the port will be chosen as the Root Port.
Port Cost – A Port Cost can be set from 0 to 65535. The lower the number, the
