Configure and display the interface settings for an MST
instance

You can configure and display the interface settings for a Multiple Spanning Tree (MST)
instance.

An interface can become diagnostically disabled (D-Disable) when a severe error
condition occurs for DOT1S. The most common cause is when BPDU flooding occurs.
The flooding criteria are such that DOT1S receives more than 15 BPDUs in a 3-second
interval. (Other causes for a DOT1S D-Disable condition are very rare.)

To configure and display the port settings for an MST instance:

1. Launch a web browser.

2. In the address field of your web browser, enter the IP address of the switch.
