Using the Console Interface 55
♦
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 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.
♦
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.
