OH MY GOD YES THIS. I've been tearing my hair out for literally months trying to figure out how to get my 6450 to pull Global addresses from my upstream pfSense router. I'd recently come to the conclusion that the limited L3 stack on the 6450 just won't support it, but hadn't tried with my 6610 yet (still trying to figure out the best way to integrate into my network).Thanks @fohdeesha and others for all the great info here! I picked myself up an ICX6450-48P and have it running.
Does anyone know how to get the ICX6450-48P to obtain IPv6 ULA and Global addresses from an upstream router or dhcpv6 server?
I have a switch port using ipv4 dhcp and it gets the ipv4 address assignments from my dhcp server, etc so I can ssh to the switch. I've also enabled ipv6 on the port and it assigns a LLA to which I can ssh (example: ssh -6 root@fe80::6e6c:f1ef:aed2:800%internal1), but I can't find configuration options to direct the switch to also obtain an ipv6 ULA or Global address (which do work for all other ipv6 devices on my network) for that port.
