a 16-bit priority and a 48-bit Ethernet MAC
address 32768 + MAC
Priority
A relative priority for each switch – lower
numbers give a higher priority and a greater
chance of a given switch being elected as
the root bridge 32768
Hello Time
The length of time between broadcasts of
the hello message by the switch 2 seconds
Maximum Age Timer
Measures the age of a received BPDU for a
port and ensures that the BPDU is discarded
when its age exceeds the value of the
maximum age timer. 20 seconds
Forward Delay Timer
The amount time spent by a port in the
learning and listening states waiting for a
BPDU that may return the port to the
blocking state. 15 seconds
The following are the user-configurable STP parameters for the port or port group level:
Variable Description Default Value
Port Priority
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 128
Port Cost
A value used by STP to evaluate paths –
STP calculates path costs and selects the
path with the minimum cost as the active
path 200,000-100Mbps Fast Ethernet ports

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.
