Hi,
I have 2 x Cisco Nexus 9K 93180YC-EX units connected via vPC, plus a port-channel (also with vPC) back to our L3 Core (6509 VSS pair). We have a new ESX Host trying to boot via PXE to get a DHCP address but it fails each time getting a 'No offers received' message each time.
From these switches we can ping the SVI at the Core acting as the gateway for the new ESX hosts VLAN and the Core SVI has IP help addresses configured and all works fine for other servers running across the other LAN switches. The server switch port is now configured as an access port with the required VLAN. We did have it set as a trunk port with a native VLAN set but I simplified the config because we're seeing these issues.
Is there a known method / requirements for getting DHCP to work across this kind of environment? I've done this many times across a standard Catalyst setup and to be honest I assumed it would follow the same process with the Nexus units too.
Any ideas?
Many thanks
Neil
