I am observing a temporary not reply to icmp request on different switches 1920. Traffic pass through correctly but, for little time, switch not reply to ping request. In fact, IP is associated to Vlan Interface and I noted the issue using ping -t (the not reply could be appears only one time at day). When switch not reply, in the arp table is not present, and after some seconds it appears again and start to reply to ICMP. I tried from some PC and updating firmware not fixed issue. In my network are present many HP switch (2610, 2530, 5500, 1920..) and problem is only on 1920. In lab I could not simulate the issue, switch works properly, connecting this switch in my broad network issue returns.
Any suggestions?
Many thanks in advance
Marco
