Can be anything. But I assume vlan is not configured correctly on the switchports. Or icmp in not enabled on the gateway. Or you are using the wrong vlan in ahv/aos.

Are you nodes in an LACP configuration?
There is a known issue with Cisco Nexus Switchs that when the host start up that the NICs get the same MAC address and disrupt the uplink to the switches.

That is the only time where we have had issues getting it on to the network.

I assume all the essential stuff has been checked
1. VLANS are in the VLAN table and configured on the switch ports
2. Upstream uplinks allow the VLAN

@JeroenTielen thanks for prompt reply maybe i assume networking configuration is incorrect or something is misconfigured at switch end.
