Using the BayStack 303 and 304 Ethernet Switches
Spanning Tree General Information
The Spanning Tree General Information screen displays the following parameter settings:
•Aging Time
This field allows you to define how many seconds a learned MAC address can be inactive before it is “aged” or unlearned. This field is configurable in the range of 10 to 1,000,000 seconds with a default of 300 seconds.
•Bridge Priority
This field allows you to determine which bridge within the network is designated as the root bridge (bridge with the highest priority). This field is configurable in the range of 0 to 65535 (where low number = high priority) with a default of 32768.
•Designated Root
This information is the identifier for the root bridge.
•Root Port
This information identifies the port which offers the lowest cost path from this bridge to the root bridge.
•Hello Time
This field allows you to define how many seconds elapse between hello time messages that are sent from this switch to all other switches, if the Spanning Tree Protocol has defined this switch as the root switch. This field is configurable in the range of 1 to 65535 seconds with a default of 2 seconds.
•Max Age Time
The maximum age of Spanning Tree Protocol information is learned from the network on any port before it is discarded. This field is configurable from 1 to 65535 seconds with a default of 20 seconds.
•Forward Delay
This field allows you to define how many seconds the switch delays forwarding frames after a network topology change. The field value is configurable in the range of 1 to 65535 seconds with a default of
15 seconds.
