Link Aggregation

Does VMS networking support (or are there plans for future support of) IEEE 802.3ad Link Aggregation or Ether Channel?

It's not on the roadmap

You can always contact HP to ask the product manager. The contact HP links on the HP VMS web site do work.

Not that I know of, and not that I can locate at the HP OpenVMS web site.

HP seems to call its version of link aggregation "auto port aggregation", based on what I can turn up.

Ping one of the OpenVMS business managers, and ask? It would not surprise me that there's more going on, but I don't know that.

MultiNet and TCPware common_link facility provides both fail over and load balancing among the interfaces that are configured as a common_link. I have not read the 802.3ad specification, so I do not know whether or not it really meets the specification. Note that use of such facilities can cause our of order packet delivery, so if the system receiving the packets does not do a good job of handling out of order delivery you may end up with a loss of performance.
