By default, Spanning Tree is disabled on the MIL-S3580. The switch uses the
IEEE802.1D Spanning Tree Protocol (STP), when enabled, to ensure that only one
path at a time is active between any two nodes on the network. In networks where
there is more than one physical path between any two nodes, STP ensures a single
active path between them by blocking all redundant paths. Having more than one
path between a pair of nodes causes loops in the network, which result in
duplication of messages, leading to "broadcast storms".
As recommended in the IEEE 802.1Q VLAN standard, the MIL-S3580 uses a
single-instance STP, regardless of whether VLANs are configured on the switch.
The Spanning Tree status can be changed with the
spanning tree protocol, you must complete the Priority and Time fields with
appropriate values. Note that you can choose to leave a menu screen without
applying any changes you had made at any time by pressing
confirm with
x STP Bridge Priority - The range is 0 to 65535. This range specifies the priority
value used along with the switch’s MAC address to determine which device in
the network is root for all the spanning tree switches. The lower a priority value,
the higher the priority. The default is 32768.
x STP Bridge Max Age - The range is 6 to 40 seconds. This range specifies the
maximum received message age the switch allows for STP information before
discarding the message. The default is 20 seconds.
x STP Bridge Hello Time - The range is 1 to 10 seconds. This is the time
between messages transmitted when the switch is the root. The default is 2
seconds.
x
STP Bridge Forward Delay - The range is 4 to 30 seconds. This is the time
the switch waits before transitioning from the listening to the learning state and
between the learning state to forwarding state. The default is 15 seconds.
