3400cl and ESXi 5.0 trunking

[kurtbuff]

All,

I have a new VMware ESXi 5.0 server that I'm trying to set up for trunking with my 3400cl. I can ping and connect with the server when the 4 NICs from the server are connected the switch and the ports to which they are connected are tagged to the VLAN, but as soon as I trunk the ports (trunk 1-4 trk1 trunk) and tag the trunk to the VLAN I lose connectivity.

The relevant fragment of the non-working configuration are below.

Thanks,

Kurt

What load-sharing mode are you using on the ESXi vSwitch? You should be using route based on IP hash.

[kurtbuff]

Route based on IP Hash is set, and all 4 NICs attached to the vswitch are set as active.

If I merely tag ports 1-4 in the VLAN, I get connectivity, but as soon as I trunk them, I can't ping the server, either from the serial console on the switch or a machine attached to the swtich.

I found it. The route settings on the Management port group didn't match the route settings on the vswitch.

Once both of those had been set to route based on IP hash, I got connectivity.

Good to hear you've got it solved!  Thanks for taking the time to document your solution.
