♦ 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. 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 Sec) 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
