Not able to ping ESXi 5.5 recently installed on x 3850 OEM

Recently I have installed Esxi 5.5 on IBM x 3850 Server and configured for management ip, but even after reboot I am not able to connect/access /ping esxi using management ip.

Only access I have is with hardware remote console (RSA)

Is there any more config to be checked for issue on esxi 5.5 config because network part is already done for required connectivity?

Please advice best practice to get this rectified with required checks to be done using command line at esxi/hardware level

Nic I have selected are already showing connected...but no ping/access

also please confirm to check the nic conncetvity/port config/trunking to switch.
Thanks

I would check

1. Update the server using the latest firmware especially for the physical nics.

2. update and check the drivers/vibs for the network interface.

3. Is the server on the HCL?

Is this an upgrade or new installation.

If you have any teaming, vlan, trunking defined, I would remove it all, and test with a single network interface connected to the vSwitch.

Try with a single NIC connected - maybe your switch does not handle multiple paths.

Then double-check ESX TCP/IP configuration:
- is network MASK properly entered?
- are you sure there's no duplicate IP conflict with ESX's IP address?

Is there some NAT inbetween? Maybe port 80 automatically jumps to HTTPS on port 443, and your NAT is not configured to forward port 443 to desired ESX IP?

All updated as this is new box handed over by hardware /network team to do esxi installation which cam as OEM with IBM X 3850 Rack Server.

2. update and check the drivers/vibs for the network interface.

is it required for fresh installation ? and nic status is up n connected showing on host

3. Is the server on the HCL?

Yes, Server came with OEM image of esxi 5.5

Is this an upgrade or new installation.
New Installation

If you have any teaming, vlan, trunking defined, I would remove it all, and test with a single network interface connected to the vSwitch.
checked with single nic,any other way to check it more from host side for issue if any due to esxi installation /configuration?

Tried but no luck

Then double-check ESX TCP/IP configuration: how can we check  it more, as re verified for config i have given
- is network MASK properly entered? yes
- are you sure there's no duplicate IP conflict with ESX's IP address? no duplicate ip,any way to get this verified

Is there some NAT inbetween? Maybe port 80 automatically jumps to HTTPS on port 443, and your NAT is not configured to forward port 443 to desired ESX IP? how to check that from host ?

I would still check firmware and network interface updates. despite what i'm told by other idiots.

ESXi installaton is simple, nothing need to be done.

If you change Static to DHCP, does it get an IP Address.

getting that 169 ip

it's not passing traffic onto the DHCP network.

I would connect to a laptop using a cross over cable, and test, if it's the physical network or ESXi server network interface or cable....

try all the nics on the server.

Andrej PirmanCommented:
I remember once I couldn't get ESXi traffic to pass through by any means...untill I put a dumb gigabit 8-port switch inbetween ESXi and the rest of the network. Some weird and still unknown incompatibility between NICs.

Try pinging one LAN machine from ESXi cli. Then see ther LAN machine's ARP table and see, if ESXi's MAC address gets through.

To test as Andrew says, direct connection between ESX and laptop, you actually do not need crossover cable AFAIK, so you can do it right now. Put them both in same subnet and pring each other. If this passes, then problem is within your SWITCHING or ROUTING network.

Thanks,but here i have access through RSA only, so can do possible  task through RSA for remote box.

You will need to diagnose outside of RSA for this issues. e.g go to the physical server.

and if you are not at the physical server, it might not be connected with the correct cable, or the correct network port.
