Configuring MSTP on a product

You can configure MSTP attributes from the VLAN View tab or the Product View tab on the VLAN Manager dialog box.

1.Perform one of the following tasks to select the VLAN on which MSTP will be configured:

•On the VLAN View tab, expand the list of VLANs and select one or multiple VLANs on which MSTP will be configured.

•On the Product View tab, expand the product, product group, or IP subnet folder that contains the products on which the VLAN you want is configured. Then expand the entry to display its VLAN and select the VLAN where MSTP will be configured. You can select more than one VLAN from this tab.

Either of these methods enables the STP button on the VLAN Manager dialog box. For either view, you can use the Search tool to look for the VLAN on which MSTP will be configured.

2.Click the STP button on the VLAN Manager dialog box to display the STP Configuration dialog box.

3.Select the target switch, VLAN, or port from the Target Context list.

4.Select MSTP from the Spanning Tree list.

The products on which the VLAN is configured appear on the STP Configuration dialog box (Figure 325).

5.Select the Enable check box if you want to enable MSTP.

6.Enter a value in the Priority field to identify the root bridge in a spanning tree (instance of MSTP). The bridge with the lowest value has the highest priority and is the root. A higher numerical value means a lower priority; thus, the highest priority is 0. The values range from 0 through 61440. The default is 32768.

7.Enter the number of seconds a bridge waits (the listen and learn period) before it begins to forward data packets in the Forward Delay field. The values range from 4 through 30 seconds. The default is 15 seconds.
