Good Afternoon
I'm currently facing a layer 2 issue with one of our IRF devices (7 members of HP 5130-48G-PoE+-4SFP+ (370W) EI JG937A)
It's happening only at 1 location.
From this IRF stack, I have customer /client without any issue but have some connectivity issue with other.
The issue is not related to any physical layer (I mean, Transceiver/fiber/RJ45 either from downlink or uplink from the irf itself)
I enabled some notification to 1 port with the issue (I have at least 1 port by switch concerned)
I see that the CAM is updating and deleting @MAC (I used mirroring port and when the switch is deleting the mac, I confirm there is network activity from the user behind)

We're using 3507P08 but, In my opinion, it's not related to software. Last summer I upgraded the IRF and the customer told me that the issue was already there.
Kind regards
