Okay, I am starting to understand better. I was thinking more like the ICX 7150 having a function similar to 'IPv4 helper address' where the ICX 7150 would forward router adverts and other IPv6 info from the edgerouter to it's associated VLANs via a transit link (fd00::/127).But

I see what your saying, so it's like the edgerouter receives the /60 prefix from the ISP, probably has to take one /64 subnet for itself, but then has its own prefix delegation server to delegate the remaining 15 /64s to the ICX 7150, and it would assign those to the VE's accordingly.

I guess now I need to research if the edgerouter can delegate prefixes.
As far as I can tell, yes that's what you would need to do. Prefix Delegation is part of the DHCPv6 spec, so if it can do DHCPv6 I'd be a bit shocked (and disappointed) if it couldn't do PD.

That said, you MIGHT be able to skip PD and do DHCPv6 assignments using DHCPv6 Relay (which is what the helper addresses are for IPv4). I tend to forget that because of my gateway being a pfSense box and pfSense flat out refusing to properly implement DHCP Relay configurations for unattached subnets, but that very much could work. But I believe you'd still need to do DHCPv6 rather than SLAAC if you were going to do it that way.

Do EdgeRouters work as DHCPv6 Prefix-delegation servers yet? | Ubiquiti Community
Disappointing indeed.

Unfortunately, I have clients that can only use SLAAC for IPv6, so utilizing DHCPv6 for address delegation is not an option for me. Android's lack of DHCPv6 support frustrates enterprise network admins

Did anyone try to backup licenses from icx6610 over serial console? Bought a ICX6610 which happened to have one 4-port POD license and I want to back it up just in case.
Found 2 license strings so far, each is present 2 times in the memory dump. Are there ways to test if the strings I found are correct?

the page you were following has instructions on how to put the license strings in a license xml file, then just import it and see if it says valid or not

Any of you guys know if it's possible to do multicast routing on 6450?

Since I configured my 6450 as L3 switch between my vlans I've had problems playing games that need portforwarding/upnp my pfsense box did this before, but since it's not in the same broadcast domain anymore it obviously doesn't work.

I was hoping to somehow get it working again, as I'd otherwise have to do manual pat for all the games that need it.

can you give me an example? Is your 6450 fully licensed? I guess they could be 6610+ only but I remember the 6450 datasheet specifically calling out multicast routing

Well...

device(config)# router pim
device(config-if-e1000-1/1/22)#ip pim

Don't work, but I'm not sure if any of the commands will show up when I can't even enable PIM.

Code:
(config)#show license
Index    Lic Mode        Lic Name               Lid/Serial No  Lic Type    Status     Lic Period    Lic Capacity
Stack unit 1:
1        Node Lock       ICX6450-PREM-LIC-SW    -snip-         Normal      Active     Unlimited         1
2        Node Lock       ICX6450-10G-LIC-POD    -snip-         Normal      Active     Unlimited         2

well damn, guess it's only on the 6610 and up

So I've been lurking and learning and decided to grab some switches for playing around and helping with my network upgrade. I got an FCX648-E with the FCX-4XG module installed for a decent price and a ICX6430-C12 mainly due to being fanless (it will be in the house near the TV, etc.) I upgraded both of them thanks to @fohdeesha docs and tutorials. Neither seems to recognize when a transceiver is inserted, am I missing something in the setup process? I'm using Brocade 57-1000012-01 which should be 850nm mm/sr transceivers, my cables are OM3 MM

My plan was to have the FCX648 in my computer room with my unRAID server doing pfSense outputting to the FCX648 and uplinking over OM3 fiber to the ICX6430 in the main house where it can then handle VLAN/POE etc for the main house, leaving all the noisemakers in the detached office.
After a little more reading I decided to check the license record on the FCX648 and post it.
Any ideas, I'm willing to learn but a bit over my head here.
Thanks in advance

the icx6430 has no 10gbe, that's why it's not in my post. the SFP ports are SFP, not SFP+, so the 10gbE SFP+ optics you're putting into them indeed won't work

for the FCX, can you post the output of "show module" and "show media e 1/3/1" with a 10gbe optic in the first 10gb port

U1:M2 FCX-4XG 4-port 10G Module (4-SFP+) OK 4 748e.f821.f340

show media does nothing just returns to cursor with no message

I tried multiple sfp transceivers with the PN I previously gave and also a Finisar FTLX8571D3BCL that came with the switch.

The 6430 only being 1gbe capable isn't a big deal unless that means it can't negotiate with the FCX. I had noticed that in the specs but since my internet is only 1gig I figured it wasn't a deal breaker as long as they can communicate, guess I should have asked some questions before pulling the trigger. What started this whole mess is the need to run cabling between buildings and for it to be non-conductive, so I went down the fiber rabbit-hole.
Thanks

So I got my ICX 6610 switch and followed the directions and everything is up and running except for a couple issues.

1. The first 2 ports are not working at all. I plug in a network cable and the lights come on, but no connection to my router nor other devices.
2. I can't seem to get my Ubiquiti UAC-AP-Pro to work with the switch POE. I am thinking maybe my cable is crap so doing more testing, but what do the "class" levels mean with the inline power?

One other question I just thought of, is there a certain way people setup the switch port with which they connect their router to?

Any help would be appreciated.

Thanks,
Josh

it will link with the fcx, but you'll need 1gb sfp modules to match on the fcx end, and in the fcx config you'll need to set that port to 1gbe (if i remember right that module will try and default to 10gbe). "show media e 1/3/1" with an sfp module in the first module slot returns nothing? even if the slot is empty, it should return empty:

Code:
telnet@FCX2>show media e 1/3/1
Port   1/3/1: Type  : EMPTY
