Hello,
We are in the process of migrating to new hosts and new 10Gbit network.
Current ESXi (5.1) hosts use vSphere Standard Switch, each host with three 1Gbit NICs teamed as active.
Physical switchports are not port-channelled, so load balancing is set to "Route based on the originating virtual port ID" on vSwitch.
The new ESXi (5.5) hosts also use vSphere Standard Switch.
Each host has two 10Gbit NICs uplinking to a separate Nexus 6000 switch, which uses Virtual Port Channels.
In the vSwitch, NICs are teamed as active, and "Route based on IP hash" set on vSwitch and Management port
On Nexus switches The VPCs are configured as "Static" Etherchannels - in order to support vSphere Standard Switch.
Teaming seems to be working - we can unplug a cable or shutdown a physical switch port without losing connection..
But if a NIC is removed from the team on the vSwitch, connectivity becomes flaky, at best - for both Management and VM traffic.
Is this intended behaviour?
I know that a "team" with a single NIC does not make much sense - but I foresee isues with this in future NIC migrations.
BTW: Nexus Switches use "source-dest-ip" for load balancing.
Best regards
Martin
