Parameter Description
Spanning Tree Status Indicates whether Spanning Tree is enabled for this VLAN
New Priority Bridge priority is used by the Bridge ID to determine which bridge will be
the root bridge. Bridge ID consists of this bridge priority concatenated with
a 6-byte MAC address. You can set the bridge priority by entering a
decimal number from 0 to 65,535. Zero is the highest priority.
New Bridge Hello Time The time interval between the transmission of Configuration BPDUs by a
bridge that is attempting to become the root or is the root.
New Bridge Max Age The maximum age (in seconds) of Spanning Tree Protocol information
learned from the network on any port before it is discarded.
New Bridge Forward Delay This time value (in seconds) controls how fast a port changes its spanning
state when moving towards the Forwarding state. The value determines
how long the port stays in each of the Listening and Learning states, which
precede the Forwarding state. This value is also used, when a topology
change has been detected and is underway, to age out all dynamic entries
in the Forwarding Database.
New Aging Time The timeout period in seconds for aging out dynamically learned
forwarding information.
