Hello there,<\/p>\n
are you one of these ppl using ESXi on a small server\/pc under your desk to evaluate \/ develop software?
\nAre you one of these fitting the whole ESXi World into one machine, one one IDE \/ SATA drive and without any other VMWare Administrative Instances as your Vi\\Vsphere Client? Are you one of these ppl that does not have one real 10 Gig Interface for each VM Machine into its server - but do desperatly need to connect an real pc to just one VM? No problem! Here we go! All we need is an Switch with vlan Trunking. I used an Cisco c3560-poe8 for this, as it is my main work switch.<\/p>\n
So you just need these snipets on the switch side:<\/p>\n
This is going to activate ip dhcp snooping globaly on the switch these are the vlans, one main, one \"test\" for the vm normal client port vm client port which does access vlan 999 vm server port, which does access normal vlan 1, and does trunk the rest Thats it! And then, you can do pxe, dhcp, sunray, and allll you want!<\/p>\n Cheers,<\/p>\n Nico<\/p>\n
\n(which means only marked ports are allowed to answer an dhcp request, thats important!)
\n
\nip dhcp snooping vlan 1-4094
\nno ip dhcp snooping information option
\nip dhcp snooping

\n name main
\nvlan 999

\n
\ninterface FastEthernet0\/3
\n switchport access vlan 999
\n spanning-tree portfast
\n<\/code><\/p>\n
\n\" ip dhcp snooping trust\" means, that this port is allowed to answer dhcp requests

\ninterface FastEthernet0\/7
\n switchport trunk encapsulation dot1q
\n switchport trunk native vlan 1
\n switchport trunk allowed vlan 1,999
\n switchport mode trunk
\n ip dhcp snooping trust

\nIts that easy!
\nOnly thing you need to do on the vm machine is to start vi\\vsphere client, go to configuration, network, create an new port group and insert the nic of the vmware machine you want to use on the switch port (here 3 on the c3560) - and set the port groups vlan id to 999.<\/p>\n
