Bridge Settings
The parameters are described below:
♦
Bridge ID – The Bridge ID is a read-only object composed of the bridge priority and the MAC address. So in
the screen above, the Priority is 32768 and the MAC address is zero since it was yet to be entered.
♦
Priority – 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 multi-bridged 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.
♦
Port Aging – This is a read-write object that allows you to set the aging time for MAC addresses in a port’s
address table. When the time-out figure is reached, the bridge will remove the MAC address.
♦
Max Age – 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 Bridge, 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 – 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 – 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.
