Parameters that you can change are:
•
Spanning Tree Protocol – This drop-down menu allows you to enable the Spanning Tree Protocol
setting.
•
Bridge Max Age (6-40 Sec) <20> – The Maximum Age 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) <2> – The Hello Time 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) <15> – The Forward Delay can be 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) <32768> – A Bridge Priority can be from 0 to 65535. Zero is
equal to the highest Bridge Priority.
