♦ Max Age (6-40 sec) Maximum Age is a read-write
object that can be set from 6 to 40 seconds. At the
end of the Maximum Age, if a BPDU has still not
been received from the Root ridge, 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.
♦ Hello Time (1-10 sec) Hello Time is a read-write
object that 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.
♦ Forward Delay (4-30 sec) The Forward Delay is a
read-write object that can be set 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.
♦ Bridge Priority (0-65535) A Bridge Priority is a
read-write object that can be set from 0 to 65535.
This is the priority number of the bridge. The value
is used in conjunction with the bridge MAC address
to set the bridge ID, which in turn is used when
determining the root bridge of a multibridged
network. The root bridge is responsible for
processing data packets when network loops occur.
The smaller the number set, the higher the bridge
priority is. The higher the bridge priority, the more
chance the bridge has of becoming the root bridge.
Zero is the highest priority.
