ESXi 6.0.0 Won't Connect to Network

I recently installed ESXi on a Dell T1700 which has an Intel i217-LM NIC.

The installation was 'flawless', but for some reason I can't communicate with the host.   So here's some facts:

  • on the command line, I check the network using esxcli-nics -l and it shows the network as being up (and connected)
  • when using DHCP the server will NOT get an address from the DHCP server
  • when I put in the static address I cannot ping the ESXi host, nor can I ping the gateway FROM the ESXi host
  • the lights on the network show that I have a link (1Gbps) and that there's some communication going on

As a secondary approach, I connected my laptop directly to the ESXi host and using the following addresses was not able to ping it.

DeviceIP AddressMask Gateway
ESXi Host10.56.25.239255.255.254.00.0.0.0
Laptop10.56.25.238  255.255.254.00.0.0.0

Any thoughts on what's going on here would be HIGHLY appreciated.

Hello,

          For one, you definitely need the gateway to be set for vmk to understand which interface to be used to transmit which ip ranges. You can find out this by esxcfg-route -l. Next, it would be also good, if you can post out esxcfg-nics -l output. Sometimes, I have seen peeps having 2 nics, provide uplink for vmnic1, whereas management is vmnic0.

so in short, please do help on the following outputs:

1. esxcfg-route -l

2. esxcfg-nics -l

3. esxcfg-vswitch -l

Thanks a ton,

John,

In recent days,there are network adapter are hyper converged adapter(FCoE + Ethernet).Do you have any specific network settings related to network adapter.

1.Can you check the vLAN tagging are properly tagged in the switch end or in esxi end.

2.Duplex,MTU and network connected status in the DCUI console(Try to connect the host one by one NIC to find out working one)

In Secondary approach,try to change the gateway(laptop IP) to esxi host and vice versa.

Alternate way try to install different OS in the server(If possible) to sort out it is not the NIC issue.
