I have 7 N3000 switches in a stack.
There is 1 N3048 and 1 N3024 These to are number 6 and 7 and they are where all my servers get plugged in to.
The other 5 switches are N3048p where all clients get plugged in to.
We operate 4 VLAN's
1 - Normal Clients
2 - PCI DSS clients
3 - VOIP phones
4 - Servers
Everything is set up and seems to work fine, however every now and again there appears to be a blip, I get an email from our phone system saying it has lost connectivity to another server. All the desktop apps that connect to the phone system crash and my hyper-v machines report they have lost connection to the storage array and freeze all machines.
It appears to happen at random maybe a few times a day, but then it wont happen again for a while. I have pings running at the minute to try and find out when the connections are dropping but I cant seem to find anything in the event logs.
Is there anything I can do to try and trace down what is causing this issue? It is causing all sorts of headaches at the moment.
We also have a blade chassis which has 2x 1gb switches which are connected over 10g to the 10gb ports on the server switches. These appear to work without issue.
Thanks in advance for any help.
