Snagged an ICX6610 last year due to the popular thread here and my passing familiarity with them at a previous job. I'm using all but 1 of my 10g SFP+ ports up front, so when I bought another pair of ESXi nodes I wanted to use one of the QSFP+ breakout ports on the rear, but I'm running into some oddities. I'm using 1/2/6 as a 40g port to TrueNAS with no issues and had used 1/2/1 previously without trouble.

I've got 2 Cisco QSFP+ to SFP+ breakout cables, I believe they're passive but I'm not 100% sure on the model number, but can probably dig it up if that's helpful.

When I plug into the top QSFP+ it'll link up port 1/2/5 but not 1/2/2 - 1/2/4, only port 5. When I plug into the bottom QSFP+ port none of the ports 1/2/7 to 1/2/10 light up. They did briefly earlier today for a little bit but stopped seemingly after I added them to a VLAN, but I couldn't get them back up even after reverting the changes. I swapped between the 2 breakout cables and the behavior was the same. Also tried plugging the SFP+ ports 1-3 into known good hosts and they didn't link, but they work fine when connected to the front SFP+ ports.

I'm curious if I need an active breakout cable, or if there's something else I'm missing.

Here's snippets of my running config for the pertinent ports:
Current configuration:
!
ver 08.0.30tT7f3
!
stack unit 1
module 1 icx6610-48p-poe-port-management-module
module 2 icx6610-qsfp-10-port-160g-module
module 3 icx6610-8-port-10g-dual-mode-module
!
global-stp
...
interface ethernet 1/1/48
port-name Uplink to Firewall
dual-mode 1001
!
interface ethernet 1/2/6
dual-mode
!
interface ethernet 1/3/1
port-name Ravager ESXi VM Uplink
dual-mode
speed-duplex 10G-full


It looks like it's being detected in show media:

Port 1/2/1: Type : EMPTY
Port 1/2/2: Type : EMPTY
Port 1/2/3: Type : EMPTY
Port 1/2/4: Type : EMPTY
Port 1/2/5: Type : EMPTY
Port 1/2/6: Type : 40GE-Passive Copper
Port 1/2/7: Type : 40GBASE-Passive Copper
Port 1/2/8: Type : 40GBASE-Passive Copper
Port 1/2/9: Type : 40GBASE-Passive Copper
Port 1/2/10: Type : 40GBASE-Passive Copper


Thanks in advance for any insight.

Side note of an update - I'm thinking I'll just order another ICX6610 and stack them using the breakout ports. It looks like that ought to be possible based on chatter in the main Brocade thread. If anyone's done that before, a code snippet would be great.

I did order a 40g breakout cable to tide me over and see if it's an issue with the ports while I wait for the switch.

Hate to necro an old thread, but this is very similar to the issue I'm currently having. Did you ever figure this out? My bottom QSFP+ breakout port works fine, all 4 10g links are perfect. The top breakout port only links 1/2/3 and 1/2/4, but not 1/2/2 or 1/2/5. If I swap the top and bottom breakouts (They're both on identically hardware/software configured ESXi hosts), the problem stays with the switch port, and the previously only 2/4 connected server links all 4/4, so I believe the cables are fine. Both 40g ports work perfectly and always have. I set up the switch following fohdeesha's guide and removed all the stacking junk, evidenced by the bottom breakout port working.

Code:
Port 1/2/1: 40G-SR4
Port 1/2/2:  Type : 40GE-Passive Copper
Port 1/2/3:  Type : 40GE-Passive Copper
Port 1/2/4:  Type : 40GE-Passive Copper
Port 1/2/5:  Type : 40GE-Passive Copper
Port 1/2/6:  Type : 40GE-Passive Copper
Port 1/2/7:  Type : 40GE-Passive Copper
Port 1/2/8:  Type : 40GE-Passive Copper
Port 1/2/9:  Type : 40GE-Passive Copper
Port 1/2/10:  Type : 40GE-Passive Copper
They seem to all be there in 'show media'. If I do a 'show run eth 1/2/2' and the same on 1/2/3 they're identical apart from 1/2/2 not being up.

Nothing I can think of to do makes 1/2/2 and 1/2/5 come up. Very open to suggestions!
