HPE 1920s PoE+

[Vicebal]

Hi,

I've got HPE 1920s switch with PoE 48 ports.

I've got connected to it Cisco WAP 581 working in dual link.

The problem occures on the switch, ports are randomly down and up. The wifi is reconnecting and users do not have an Internet.

Hi,

Interface 3 and 27 looks to be part of TRK3. as per the logs, what is the configuration on the peer device. Is the other end too a trunk/aggregated link, there could be a configuration mismatch. Can you share the configuration of both the devices.

Hi,

Just curious to know the status, were you able to check the configuration on the peer device
