Default Spanning-Tree Configuration
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.
A relative priority for each
port –lower numbers give a higher
priority and a greater chance of a given
port being elected as the root port
A value used by STP to evaluate paths –
STP calculates path costs and selects
the path with the minimum cost as the
active path
