An entry of 0 denotes the CIST (default MSTI). Priority Enter the priority in this field. The available range of values is from 0 to 61440. Click the Apply button to accept the changes made. Click the Edit button to re-configure the specific entry. Click the View button to display the information of the specific entry. MSTP Port Information This window displays the current MSTI configuration information and can be used to update the port configuration for an MSTI ID. If a loop occurs, the MSTP function will use the port priority to select an interface to put into the forwarding state. Set a higher priority value for interfaces to be selected for forwarding first. In instances where the priority value is identical, the MSTP function will implement the lowest MAC address into the forwarding state and other interfaces will be blocked. Remember that lower priority values mean higher priorities for forwarding packets. To view the following window, click L2 Features > Spanning Tree > MSTP Port Information, as show below: Figure 7-32 MSTP Port Information window The fields that can be configured are described below: Parameter Description Port Instance ID Internal Path Cost (1-200000000) Select the port you want to configure. The MSTI ID of the instance to be configured. Enter a value between 0 and 15. An entry of 0 in this field denotes the CIST (default MSTI). This parameter is set to represent the relative cost of forwarding packets to specified ports when an interface is selected within an STP instance. Selecting this parameter with a value in the range of 1 to 200000000 will set the quickest route when a loop 78
