vmware - hp procurve lacp / trunk

Cisco’s Etherchannel and HP’s LACP are very similar – probably why I assumed both are supported by vmware. But as per below – it is not the case.

From a procurve perspective the differences between a “trunk” and “static lacp” trunk is the total bandwidth per connection. A typical end point on a “trunk” trunk can transmit various connections down both pipes, but only receive down one – sometimes refered to as TLB (transmit load balancing). In vmwares case when you are using a “trunk” trunk you will have ip hash set as a load balancer, effectively meaning a different nic will be used on the vmware side for each connection a virtual machine makes.
