Auto-forming vLAG on access ports

Hello,

I love the idea of automatically forming ISLs between VDXes, and that why I have got a question about why not automatically form vLAG on access ports between several CNA ports, installed in the same compute box, and several VDXes of the same logical chassis/fabric? For example, if compute administrator configures NIC teaming on his side then fabric understands that and configure vLAG on its side. As a result - compute administrator gets HA connection between computer and switching fabric without asking help of networking administrator. How do you like such idea?

Re: Auto-forming vLAG on access ports

Honestly? There are many pifalls that can occur with an vLAG between different vendors - for me it would be enough when all my manually configured vLAGs would work! :-)

Re: Auto-forming vLAG on access ports

There are not so many parameters on a switch's side that have to be tried in hope to make NIC teaming working. I assume that, for converged Ethernet with FCoE, multiple redundand connections between computer and switches - "must have". I think that auto-configuration feature would significantly decrease time of hardware deployment while consuming less network administrators' work time. In case of auto-configuration failure, server administrators always have an option to do it manually or ask for help.
