How to View Memory Usage on HPE 2520-24G-PoE Switch (J9299A)

Hello All,


Our IMC has detected that one of our Switches, a 2520-24G, is running at 100% Memory Usage. If I view the switch in person the lights are lit up solidly. Traffic however seems to be operating normally; only around 4 ports are actually in use aside from the uplinks.


I've dabbled in HPE equipment in the past, but with respect of troubleshooting faults my experience is limited.


How would I go about detecting this fault? I can't find anything on the web that screams out to me a solution.


Any help or advice would be very much appreciated. This is my first post, so I aolpogise in advance if I've posted in the wrong place.


All the best,

Through CLI there is a command to gather, among other things, switch's memory utilization: show system information


switch# show system information
