Here are the steps to find the full list of devices with duplex mismatch:

1. Navigate to the NA home page
2. In the "Or...'Search For'" selection box.
3. Select "Events".
4. In the resulting page "Search For Event"
5. In the "Summary" section specify "Device Port Duplex Mismatch Detected".
6. Select the "Host Name" and the "Device IP" columns for display.
7. Select the "Search" button at the bottom or near the top of this page.

This will list all the occurrences of the Duplex Mismatch on the devices.

If your requirement is to find the current set of devices with Duplex Mismatch:

1. Please run the "NA Duplex Data Gathering" diagnostic for all the devices.
2. Take note of the time
3. Once the diagnostic completes, specify that time in the "Date" filter at the top of the "Search For Event" page. This will insure the latest set of devices with the duplex mismatch will be displayed.
