Link Aggregation + Windows 2012 R2

I have 3 HP servers connected to an HP 5700 Switch FF and need to connect two Ethernet boards per server to build a TEAM Windows by LACP.
Just 1 raised the TEAM, the other two give LACP negotiation error.

What you could be missing?

Re: Link Aggregation + Windows 2012 R2

There are a number of things to look at both on the server and the switch. You have 3 ports bound to the Link-agg group.

 

I haven't worked with the Windows teaming software in many years as we virtualize everything on VMware. However you may want to make sure that it is compatible with LACP. Sometimes they may only do Cisco Etherchannel or Static aggregation.

 

I'd try changing from dynamic to static after removing the ports then re-add your ports to the link-agg.

Windows Server 2012 NIC teaming will not work with LACP.  The ports should be configured as individual access ports, not as a BRAGG.

That sounds really odd, so the "teammode LACP" isnt really LACP in Windows 2012?

When setting up LACP in Comware (or any switch) dont forget to enable short timers (this way the BPDUs are sent once a second instead of once every 30 second or so). Also dont forget to alter the load-sharing mode from default srcmac-dstmac into srcip-dstip or even srcip-dstip-srcport-dstport to better utilize the physical links who is part of your link aggregation.

 

Here is example on how to setup LACP on Comware devices:
