Bumblebee Troubleshooting Cheatsheet

What to do when a WAN outage occurs?

When a WAN outage occurs, you should receive an email alert (or webhook event notification). The email includes an initial analysis indicating which segment of the network has become unreachable. Follow the tips in this Troubleshooting Guide to diagnose the issue.

What to do when a site cannot connect to certain application?

Select the CPE device, run a reachability test from the CPE to the application. From the device list page, select the device -> Actions -> Ping and Traceroute. If you can ping the application from the CPE, the problem is with customer's internal configuration.

What to do when a customer complains about slow applications?

There maybe many reasons why applications are slow. Follow the steps below to rule out that the Internet speed is the problem.

1. Run a diagnostics function. Select the CPE, device -> Actions -> Get Diagnostics. Check Eth0 and Eth1 for interface errors and if they are increasing. Make sure they are running at the correct negotiated speed (For example, if the WAN is 1Gbps, the LAN Eth1 port should also be full duplex at 1Gbps).

2. Make sure the WAN and LAN interfaces have no errors or the errors are not increasing.

3. Check WAN Link utilization to make sure it is not reaching 100% (a congested WAN link).

4. Run speed tests

   1. From the CPE (may need to coordinate with the site to make sure such event is happening) to prove the Internet speed is as specified.

   2. Run a speed test from the customer browser to the CPE
