I have an issue with 2 new ESXi hosts. OS - ESXi5.0 Custom Dell ISO patched up to Build 1024429
DELL R820 with 1G network 2 ports from integrated MB NIC(Intel) connected to 2 juniper switches, one is active, one is standby lose connectivity intermittently.
When they lose connectivity i can ping neighbor hosts on the same subnet connected to the same switch but pinging default getaway returns:
"sendto() failed (Host is down)"
From esxcli I see nothing in ARP table for default getaway ip issuing a command when connectivity is lost:
esxcli network ip neighbor list
Tcpdump from esxicli shows that esxi host constantly sends ARP broadcast for the default getaway IP but never gets the response. I have actually 6 new servers and only 2 of them are having these problems. Same hardware and same settings for ESXi, This connections are for 1G Management network.
Does any have slight idea what can be wrong?
