PS with S5048F-ON ---OS9 --IPv6 Q

HI..

So recently when upgrading a PS-T ...i ran into an issue,where the ipv6 was configured incorrectly..

Following this guide below i setup the TOR (cisco 9k) for ipv6 comms..all good that fixed my issue and upgrade completed.

I have another PS-T, same issue but this is connected to S5048F - with OS9...

all the guides, kb's call out how to resolve this issues, or give example configs...but they are all for OS10.

Is there such a guide for configuration of IPv6 on  dell 5048F-ON with OS9?
Previous versions of PS must have used this at somepoint
