is it enabled yet yes/no?

I think it might be as helpful to post what you have observed so everyone can have a think about what it is as regardless of the TM status its clearly of interest.

Kelly said this 6 weeks ago:

We suspect the hump is a side effect of lack of IPv6 awareness of the DPI platform at the minute. We need to enable it, the action of which is queued with our ops guys

I would assume IPv6 traffic does not correctly identify on the DPI at the moment.

Ok Chris
If I am downloading eg. of a ftp external server, then other ipv4 traffic becomes very lossy, eg if I hold a key down in a ipv4 CLI SSH session the cursor jumps around all over the place, caused by packet loss, since tcp is self regulating this isnt normal behaviour. If I stop the download (single threaded by the way so not a torrent download flooding the line) the SSH packet loss immediatly dissapears.
If I do the same test using ipv6 ssh its fine no packet loss. So it appears to me the traffic management is hindering my connection when its multitasking, and the ipv6 seems to highlight it as ipv6 has no TM?

It's been enabled, but we don't think it is working properly.
So, based on it not working right, I think we can't really go further on this 😕
(Glad it's a trial eh? )

By not working properly it's not counting your usage in VMBU yet but we think everything else is working.

ok, this is defenitly not related to my 2-3mbit throughput issues right?

How do you check the traffic classification hex value for v6 traffic?
This is what I get from Wireshark at the moment:
