Configuring MSTP on a port VLAN
You can configure MSTP attributes from the VLAN View tab or the Product View tab.
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.
2. Click the STP button on the VLAN Manager dialog box to display the STP Configuration dialog
box.
3. Select MSTP from the Spanning Tree list.
The products on which the VLAN is configured appear on the dialog box.

4. Select the target switch, VLAN, or port from the Target Context list.
5. Specify the following information:
• Select the Enable check box if you want to enable the protocol you selected.
• Enter a value in the Priority field to identify the root bridge in a spanning tree (instance of
STP). 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.
• 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.
• Enter the number of seconds a bridge waits for a hello packet from the root bridge before
initiating a topology change in the Maximum Age field. The values range from 6 through 40
seconds. The default is 20 seconds.
• Click the Cisco Interop Enable check box to enable Cisco interoperability.
