Need some help with 3 HP Procurves 1810 - 24G switches, which we have been having some issues with lately.
All 3 using firmware P.2.10
No VLAN configured.
These 3 switches sits on a floor in our building and let users connect their computers to our LAN. Switch nr.1 and nr.2 is connected to switch nr.3 which is connected to a switch in the floor below, a HP V1810-48G using firmware P.1.15.
Every morning lately, about 1-6 users lose their connection. It varies how many of these users that loses their connection.
The rest of the users can connect fine, and don't notice anything.
The management interface for the 3 switches goes down, and cannot be pinged.
No issues on any other equipment.
The temporary solution has been to reboot them, only then can we reach the management interface again and the users who lost their connection are able to connect again. After the reboot, there are no issues until next morning.
