Instance ID

Synopsis: 0 to 16

Default: 1

The Instance ID refers to the MSTI (Multiple Spanning Tree Instance) ID. Specify an Instance ID and select GET in order to load the parameters of the page corresponding to the selected MSTI. Changes to parameters that are subsequently applied will apply to the selected Instance ID.

Note: Bridge Parameters for the IST (MSTI zero), are accessible via the Bridge RSTP Parameters menu (see section 5.4.1).

Bridge Priority

Synopsis: { 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672, 32768, 36864, 40960, 45056, 4 9152, 53248, 57344, 61440 }

Default: 32768

Bridge Priority provides a way to control the topology of the STP connected network. The desired Root and Designated bridges can be configured for a particular topology. The bridge with the lowest priority will become root. In the event of a failure of the root bridge, the bridge with the next lowest priority will then become root. Designated bridges that (for redundancy purposes) service a common LAN also use priority to determine which bridge is active. In this way careful selection of Bridge Priorities can establish the path of traffic flows in both normal and abnormal conditions.
