Hello.
It looks like HP v1910-24 switch prevents NFS mounting between 2 Linux hosts.
We have a separated server room where we have a Linux server with NFS share. Also we have 2 rooms with client computers. Network outlets in one room are connected to HP V1910-24G Switch JE006A, outlets in the second room are connected to HP V1910-48G Switch JE009A.
From room with V1910-48G it's possible to mount NFS share from server room, but from room with V1910-24G it's impossible even if I'll use the same Linux host as a client. I got an error "mount.nfs: Connection timed out"
I've compared all settings in these two switches but there are no differences. We don't use VLANs or ACLs
