VM to network connectivity

Hi Guys,

I'm in the home stretch of my VM deployment but I think I have hit my final snag.

Quick summary of where I am up to:

2x DellR710's, 1x MD3200i with two 4 port Controllers, 2x 5224 switches dedicated for iSCSI, 1x 6248 L3 switch, coupla other 5448 switches as needed around the network. Now, with some assistance fromt eh forums here I have my 2x R710 hosts talking beautifully with the Md3200i (each configured to use 4 vmnics across 2 vSwitches giving me 8 paths to the LUNs 4 Active I/O and 4 standby using VM RR) all good. I then put 6 vmnics into vSwitch 3 as a VMNetwork - IPHash failover, all active. I then created a test VM - installed as it should, using a LUN from the Md3200i - great. One small issue. No network conenctivity! Administering from a vSphere client on my lappy I can see vSwitch 3, the vmnics on it AND the Temp VM assinged to it and that the vSwitch is assigned to VLAN10. On my 6248 I have assigned the physical ports those 6 vmnics plug into to VLAN10 as well. I gave the server a static IP of 10.0.10.100. The switch has a routing interface for that subnet set to 10.0.10.254 - which I can ping from other subnets, due to routing rules. When I go to the console of that Test VM, running Windows 2008R2 Standard I can see that the VMXNET3 nic I setup during the setup phase has a Yellow exclamation mark on the icon down near the time.

What have I misconfigured?

Welcome to the Community,

With the IP hash policy, you need to setup EtherChannel on the physical switch. If your switch does not support EtherChannel, set the policy to the default "Route based on originating port id".

For details on how to configure the virtual network see http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf and http://kb.vmware.com/kb/1004048

Cheers Andre,

So with my Dell PowerConenct switches I need to create a LAG group for those particular ports and enable TAGGED vLAN10 access?? Does anything special need to be done on the vSwitch3 other than ensuring its IP-Hash failover and in vLAN10?

I can't tell you how exactly this has to be setup on a Dell switch. Please take a look at http://kb.vmware.com/kb/1001938 for the requirements. One important part is:

The switch must be set to perform 802.3ad link aggregation in static mode ON...

LACP is not supported!

Cheers Andre, I did remember reading that LACP wasn't supported. I'm out of the office now - Friday afternoon here YAY! So I'll set it up Monday and advise back here how it goes - cheers for the responses Smiley Wink
