New vSwitch only pulls IP range of 1 address

[JonLHFS]

Hello Everyone,

We recently virtualized a server that was on a separate vlan from our primary. Both vlans are at the same site and connect through the same firewall (I can fully communicate to all machine on that subnet from mine on the primary subnet). I have one of the NICs plugged into a switch which has the proper vlan assigned to it, created a vSwitch using that nic, and created a new vlan on that nic. I can see in the properties of the nic that it's pulling the proper IP scheme, but it's pulling a range of 1 IP, which is already in use by the DC.

I've deleted and recreated the vSwitch and vlan to no avail. Any suggestions?

I'm running ESXI 5.5.0.

Thanks,

If you are referring to "Observed IP range"

Observed IP range is picked up by physical traffic or if CDP has been enabled on your physical network switch.

This range is generated based on the incoming broadcast packets it detects.

Observed IP range does not show network in ESX or ESXi (1006744) | VMware KB

I don't really use this information because I think it is purely cosmetic.

Hi Bayu,

Thanks for the reply. To be honest I'm not entirely sure. When I clock on the properties of the vSwitch, edit the vSwitch configuration I see that active adapter is set the ip range of 10.1.24.94-10.1.24.94, while the other vSwitch on the other vlan shows the full range of the network.

Does that help?

Hi, yes it's the same. My reply above if you want to fix it but it doesn't really in my opinion as it is only cosmetic
