Nagios Support Forum

Hi All,

Newbie question.

What could be the reason why all Cisco Access switch that is connected to Huawei Distribution and Core gets disconnected on the monitoring from time to time. Lapse time is 2-5 minutes.

Even though we configure MST on all CIsco to match the Huawei STP protocol and configure BPDU protection on huawei.

Please see attached screenshot.

Kindly give me pointers on what to check and reason why this is happening.

Thank you so much!

Run the following command from a command prompt on your Nagios Core server
Replacing IPADDRESS with the IP of the switch, this will create a file ping.txt which you can view after the 100% packet loss alert to see if the ping command run directly from the command line shows the same issue.

Thank you!
