vSphere 5.1 vSwitch: LACP & HP Trunk

We DO NOT have vSphere Distributed Switches. We only use standard vSwitches. To my understanding, LACP is only supported in vSphere 5.1 with Distributed Switches.

We also use HP ProCurve switches. Since LACP is not available to us, can we use HP Trunks instead?

My understanding is that LACP and HP Trunks are the same thing, so I'm assuming the answer is yes?

In answer to your question, YES - You can use static trunks on your HP Kit. NOT LACP.

HP Procurve supports LACP and Static Trunks.

Static Trunks work fine with ESXi.

When you create a trunk on a HP Procurve swtich, you can create Static or LACP trunks.

Between HP kit, e.g. Procurve to Procurve - LACP can be used, between non-HP kit, static trunks can be used.

These concepts are used in an ESXi/ESX network environment.

To accomplish network redundancy, load balancing, and fail-over, you must:

    Enable link aggregation on the physical switch.

    Note: Link aggregation is also known as Ether-Channel, Ethernet trunk, port channel, and Multi-Link Trunking.

    Set up the ESXi/ESX Virtual Switch configuration to be compatible with these concepts

see this VMware KB


ESXi 5.1 and 5.5 supports LACP on VDS only.

I do believe HP switches have the LACP protocol implemented, my understanding was if you create LACP the switchports are set to trunk.

Having said that, since you have standard switches would you not want to create a NIC team on the vSwitch and have the uplinks for that vSwitch connected to an Etherchannel on the physical switch, and then use load balancing via IP hash?

Thanks to both.

dipopo: We have the vSwitch configured in NIC Team however the 1st NIC goes to our 1st core switch, and the 2nd NIC goes to our 2nd core switch.

Thus I think that's why we cant have link aggregation.

hanccocka: In the article you posted, it says:
•ESXi/ESX host only supports NIC teaming on a single physical switch or stacked switches.
 •Link aggregation is never supported on disparate trunked switches.
If our vSwitch's 2 NICs are connected to two different core switches (ProCurve), and the two core switches are connected via:

trunk A14,B14,C14,C16 Trk1 Trunk

Is that considered disparate trunked switches -- meaning Link aggregation is not supported?

are both HP Procurves the same type and configuration of switch?
pzozulkaAuthor Commented:
Both are 5304XL, and 99.9% same config.

Test your configuration to confirm working.

I'm just curious about the article you suggested. What does this mean?
disparate trunked switches
Does this config: trunk A14,B14,C14,C16 Trk1 Trunk
mean that we have disparate trunked switches?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
That configuration does not mean anything.

VMware's term of disparate trunked switches, means two different switches trunked together.

e.g. a Netgear and a Belkin!
