Tried everything else, so I got another 6610. 40gb works, but the breakout ports don't link. I tried a DAC and a 40gb transceiver and MPO-LC breakout cable to known working SFP+ modules. Show media lists 2/2/2-2/2/5 as 40G-SR4. The DAC does the same, shows as 40G passive copper, but never links. The only config on those ports is dual-mode.
I feel like I'm missing something, but I went over the docs again and everything is set as described. Stacking is disabled. The front 10g work, as do the 2x40g (2/2/1 and 2/2/6) on the back.
My switch really wants to be ID 2. No idea why.
Tried a different test, using a Brocade QSFP DAC. Connected the top breakout (2/2/2-2/2/5) to the old switch. 2/2/4 linked and appears to be moving traffic. Using all the ports on the DAC breakout, I also got 2/2/4 to link and work, but none of the others. WTF?
2/2/7-2/2/10 do not link at all, to 10G, though the show media shows the 40G passive copper module.
Another weird idea, I connected the other end of the 40G DAC to a 40G port on the old switch. It links all 4 channels of both breakout ports. Using matching fiber 40G modules and MPO fiber, 40G port to the breakout will link all 4 as well. Interestingly, 2/6 on the old switch seems to have 1 channel not working, which could explain the link problems on it.
So I know the switch hardware will link on all 8 of the breakouts, but only using a 40G port on the other side. Weird. Using breakouts I can get 1 out of 8 to work with 10G links. Using the 40G port on the other side links, but does not appear to move traffic. I didn't really think it would, but it might be interesting for troubleshooting.

2.5Gbps your looking at having to buy something, if you can, skip it, but I know many systems now and devices are doing the stop gap 2.5Gbps sell.
Best you could do is get a brocade and then some other smaller switch that maybe has a single SFP+ port to do a 10Gb link to and then has some 2.5Gbps ports on it
I decided to downgrade from 7450-24P to 7150-24 + Ubiquiti Flex 2.5G PoE to achieve 2.5Gb for the house and lower the temps. Let's see how it pans out.
What would be the Cisco equivalent of say the ICX 7650-48ZP?On the brocade side, yes - on cisco side they are quiet and power hungry
Hi all, I got a ICX6450-24P and am having trouble setting up a VLAN.
My Brocade IP is 192.168.1.3 on the native vlan 1. I can ssh and also reach it via web GUI.
Port 1/2/1 is connected via DAC to my Ubiquiti UDM SE. The Ubiquiti port is set to native vlan 1 and set to accept all vlan tags.
I want to set port 1/2/1 as a trunk line. I tried to start by adding vlan 10. When I apply command:
vlan 10
tagged ethernet 1/2/1
the Brocade switch becomes unreachable. If I remove the tagging, it comes back. I'm a bit confused because vlan 1 should still be permitted on this port? Clearly I'm missing something!
Thanks

vlan 1 is untagged - you cannot have tagged vlan 1. as soon as you designated it as tagged in vlan 10, it was removed from vlan 1. use a different default vlan, or go through the hassle of configuring dual mode to carry both untagged and tagged traffic over the same port (not good practice)
As fohdeesha mentioned ^ also it is standard practice not to use vlan 1, pick a different vlan and space them apart in case you need to add one in between
Are you connected directly to the 6450, or are you connecting through the UDM? When you are first setting up the switch, you should use direct connections whenever possible so that you don't get disconnected when making configuration mistakes.
Thanks all! I tried putting the switch on vlan 10 and changing the IP accordingly for my vlan 10 DHCP provided by UDM, but I wasn't able to connect to the switch when I did that. No doubt it's something simple... I'm not even sure if I changed the IP correctly.
I got this switch for my home lab but it appears there's a learning curve. I'm not an IT professional and this Brocade is proving much more difficult to set up than my other TP-Link managed switch. Are there any good guides out there that cover the basics? I did set up the switch using OP's guides, but I find I'm still missing some of the basics. I have so many questions, like 'how do I change default vlan'? 'how do I change the switch IP'? etc.
For sure! I am connected directly to the management port with a FTDI serial cable and using Putty.
Perhaps start by checking out youtube user/channel "Terry Henry" who covers a lot of brocade basics. E.g.
From my understanding, some of Brocade ICX7 switches, more specifically the ICX7450, had some issues with their PoE hardware resulting in the "internal h/w fault" when enabling PoE. I believe they updated the PoE hardware on those switches at a later stage. If my understanding is correct, is there any way of determining when the switch was manufactured based on the S/N and thus determine if the switch is likely to have the new/updated PoE hardware?
I have a icx7250-48p and a icx7250-48 in a stack with 4x DACs on 1/2/1-1/2/4 <-> 2/2/1-2/2/4 for maximum throughput linear stack. I have recently started to get low on 10G ports, and have started to consider what I should do if I need another 10GB port.
Can I "downgrade" the stack interconnect to "only" 2x DAC, rather than the 4x DAC I have now? Can I use those other 2x2 ports as non-stacking? I probably don't really need 40 Gb of bandwidth on the stack, I'm guessing 20 Gb would be fine the vast majority of the time.
If I can, does removing the extra 2 DAC connections save any appreciable power?

You can downgrade to any connection you want, including a single 10G link. All of the 10G ports on the 7250-48 are flexible and can be used for either stacking or regular connections.
Yes, it will save power.
No, not enough to appreciate it.
