About Diagnosis

Timeline

A timeline displays issue detection in a graph. It is useful to see multiple occurrences of the same issue. Each occurrence is represented by a bubble and a flag with a number. Hover your mouse over a bubble to display the month, day, and time-of-day an issue occurred, as well as the issue type: Association, Authentication, Networking (DNS or DHCP server issues), or Unknown. The flag shows the number of occurrences of the issue at the time.

Card

Underneath the timeline, the Diagnosis card contains data that can help you understand the issue, such as when problems were detected, the location of the connected AP, a description of the issue, and a suggested remedy.

• AH Device: The host name of the Extreme Networks device.
• User: The name of the user, if known.
• Location: The location of the Extreme Networks device.
• User Profile: The user profiles assigned to this device.
• Client MAC: The MAC address of the wireless client device.
• Case Number: A case number for your use. (This number is not linked to Extreme Networks Support.) Select Assign to access a dialog box. Enter a case number, and then select Submit. The number you entered displays here.
• Problem Type: Indicates if the issue was auto-generated by the client or initiated by an admin while troubleshooting the issue.
• Detected On: The month, day, year, and time-of-day the issue was first detected.
• Description: A detailed description of the issue, such as External RADIUS server could not accept the access request from the client or DHCP server did not respond to the client.
• Last Successful Connection: The month, day, year, and time-of-day the wireless client last connected successfully to the Extreme Networks device.
• Suggested Remedy: A solution to the issue, such as Check RADIUS server log files and verify the authenticating user's credentials or Ensure DHCP server is properly configured, reachable, and that it has enough leases available.

Events Associated with an Issue

If there are events associated with an issue, the total number of events displays, followed by a timeline that highlights events, and an information card below the timeline that describes each event. Below the card is a table populated with a description of the associated events, such as when a configuration was pushed to a device. (If no events are associated with an issue, the table is empty.) This table provides the following information:

• Show Phases: Select All, Association, Authentication, or IP Assignment phases from this drop-down menu. Select Show Probe Requests to display all probe requests related to this incident.
• Time Stamp: The month, day, year, and time-of-day the event occurred.
• Device Name: The Extreme Networks device name. By default, the Extreme Networks device name is the host name. If the host name is not available, the device name is the IP address. If the IP address is not available, the device name is the MAC address.
• Device BSSID: The AP wireless access interface MAC address.
• Event Type: The classification of the event, such as Auto provisioning, Connection Change, or Power Mode Change.
• Description: A description of the event, such as Station sent out DHCP REQUEST message.
