♦
Hold Time(Sec) Read-only object displays the time
interval during which no more than two configuration
BPDUs shall be transmitted by the bridge.
♦
Root Priority(Sec) Read-only object displays the
priority number of the root bridge of the Spanning
Tree. 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. A bridge priority ranges
from 0 to 65535, with 0 being the highest priority.
♦
Bridge Max Age (6-40 Sec) The Maximum Age is a
read-write object that can be 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.
♦
Bridge Hello Time (1-10 Sec) The Hello Time is a
read-write object that 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.
♦
Bridge Forward Delay (4-30 Sec) The Forward
Delay is a read-write object that can be from 4 to 30
