Brocade ICX Series (cheap & powerful 10gbE/40gbE switching)

[adman_c]

OK. I've been banging my head against this for a bunch of hours and I would love it if someone could just point out where I'm being dumb. I cannot for the life of me get my 7250 to route between VLANs. I'm running pfsense/opnsense (virtualized and switching between back and forth between the two while I get my opnsense install fully operational--for the purposes of this question, it doesn't matter which firewall I'm running). I have a bunch of VLANs--more than I need, but whatever. 3 of the VLANs are trusted, and I want to be able to route between them via the switch rather than going out to the firewall. The rest of the VLANs I want to go ahead and use the firewall to the extent there needs to be routing between them (rare), because I'm substantially more comfortable with filter rules than ACLs. At the bottom of this message is my current running config, and here is the output of 'sh ip route':

SSH@coreswitch(config)#sh ip route

6       192.168.10.0/24    DIRECT          ve 10         0/0           D    10h49m

The three VLANs between which I want to route are 2, 10, and 1010. 2161 and 2162 are transit VLANs for WAN and LAN, respectively. When I set the gateway on any of the trusted VLANs for the firewall (X.X.X.1), everything works as expected. The firewall routes between VLANs according to my rules and I can get out to the internet. On the other hand, when I set the gateway on any of the trusted VLANs for the switch (X.X.X.254), I cannot reach one subnet from another. SSH/HTTPS are both inaccessible between local subnets. However, going out to the internet works, and for some reason I can ping between local subnets. This behavior is the same whether I'm running pfsense and opnsense, and even if I yank the LAN transit cable between the switch and the firewall.

At this point I'm ready to give up and just let the firewall handle all the routing, even thought it's not quite up to the task of linespeed routing. As an aside, how much CPU do you need to max iperf on 10gbe? Brief testing I can get ~7gbit with my i3-8100t.

Anyway, any suggestions would be awesome.

Thanks!

The plot thickens! I powered up the switch again today with an H510 plugged into a port, just out of curiosity to see what would happen, and... it worked! I had PoE working happily to both the H510 and R600:

So then I restarted the switch again out of curiosity, and sure enough back to no PoE, with the same output from show inline power detail as previously (ie, no aggregate port counts showing up at all).

It seems you don't have PoE (inline power) enabled on any port.

So I think that's now eliminated as a possibility since PoE worked and then didn't work again with no change in config. If PoE only works from a cold start (ie thermally cold, not just power cycle), somehow, that's probably a hardware fault, right? Has anyone seen this before? Anything else I could check, or should this unit just go back to the seller?

Oops, now that I have the serial console connected again I see endless:

PoE Error: Device 0 failed to start on PoE module.
PoE Error: Device 1 failed to start on PoE module.

And then it hard resets slot 1, and back to the beginning I'll try a firmware reflash and return it if that doesn't help.

Have a small issue with a 7450-24... (resolved, see Edit 3)

Got it the other day, went on wiping and rebuilding according to the getting started instructions.

Connected to console, flashed the 7450 image and uboot, everything looked good.
Rebooted and got errors that the image on primary was not valid and it was using the secondary one. It continued to boot and ended up in Router-OS.

Called it a day, powered everything down.
Wanted to restart again today, assuming there was an issue with image transfer, had not touched anything.

Now the problem is that I dont have access to the serial console any more, its simply not connecting ( as i mentioned i have not touched the cable, have verified it twice since, tripple checked the settings).

The biox still boots, into routeros , get s an dynamic ip too. But, i cant login, neither on putty nor on the admin Gui.
Tried resetting via the hardware switch in case its the old image and has old pw's stored, nothing.
Maybe i have not found the correct combination for user/pw?

Its weird though that the console access is gone? can that be disabled from the OS level ?



Edit
Telnet allowed access without password... so ssh was not configured to allow access.
Now to see why the console is not working

Have not found anything...
tried flashing via telnet (older version since i am on Version 08.0.30fT213

Looks good, but after reload it has booted secondary image , despite me forcing primary one with
boot system flash primary

Seems i somehow corrupted the primary flash with that first installation

I know the instructions say to erase secondary after flashing but i am worried that would kill the switch entirely (due to no console access) if primary partition really is corrupt

Weird, there is no indication that primary is corrupt, but its not booting from it apparently...

Edit3

Ok, managed to get console access back (different box, no idea why the first stopped working all of a sudden), and the issue was that the jump from .30 to .90 was too large.
So it applied everything fine but ran into

Wrong Image Format for bootm command
ERROR: can't get kernel image!

From console i repeated the steps with 80e and matching spz which worked fine.
After that i was able to follow the regular instructions to update to the current release


Edit4 - found the problem with the com port, it was/is a vmware/Terminal services issue.

[deeceesth]

I just updated two of my ICX 7250 to 09010. One of them I can access the webui from a different subnet but the other one I can only access the webui from the same subnet. I have my switches and APs on a 172.x.x.x network and my user machines on a 10.x.x.x subnet. I have firewall rules to allow traffic to the infrastructure subnet from a list of admin IPs on the user subnet.

Is there a setting to allow/deny access to the switch admin from a different subnet?

 

[tochnia]

For info for other people who will be looking into this following combination of Hardware/Software work perfectly:

Network Card: Dell Mellanox ConnectX-3 CX354A (updated to 2.42.5000 and ports set to ETH)
Transceiver: Juniper 740-056705 QSFP+ 40GBASE-LX4
Optical Cable: Corning Fiber Optic Cable LC-LC SM DX 9/125 (Single Mode) 50 meters (cable polishing UPC)
Switch: Brocade IPX6610-48P - using 40GB "Stacking Port" 1/2/1
OS: Windows 10
Drivers: Default Windows Drivers for Mellanox (WinOF and WinOF-2 didn't want to install for some reason)

Biggest worry was about high power mode, as transceivers use 3.5W, which is supported only by ConnectX-3 Pro cards, so therefore have choose to use Single Mode Fiber cable /up to 2km with these transceivers/ rather than OM3 /up to 100m with these transceivers/.

 

[egoistdream]

Hi guys, I have one question regarding to Brocade ICX6650, I see it supports OpenFlow in hardware for SDN, I did not use until now but I know that if is properly configured you can have a virtual bgp router that will keep just the golbal routing table without the traffic to pass trough the router, my question is if any of you have used OpenFlow in any way ?

 

[silika]

Welp, I sent back the 6450 and my 6610 is lost in the seller‘s shipping department somewhere, so I guess I’m still shopping Looking at 7150s, I see that chassis fanless is only supported on the -24p and the -48p, so I guess that means that it is explicitly not supported on the -48pf, right? Or does the -48pf count as a subtype of -48p for these purposes? Has anyone tried fanless on a -48pf?

I'm the only one who has logged into the switch, and the only time I ran the serial command was when I first set up the switch while following your guide. I've had the switch off several times since then - I replaced the fans a week or so ago so it was definitely unplugged at that point! No issues until yesterday. I guess I'll just keep an eye on it - at least if it messes up again I know how to fix it now

Apparently I don't know how to fix it My UPS died today (god I hate APC) which means my Brocade shut down. On booting it up, it lost its licenses again. I get this:

1 Node Lock ICX6450-PREM-LIC-SW H4CKTH3PLN8 Normal Invalid Unlimited 1
2 Node Lock ICX6450-10G-LIC-POD H4CKTH3PLN8 Normal Invalid Unlimited 2

I've run through several times trying to add the licenses again but always end up at the same spot. Here are the last set of commands I've run:

Clear the license:
enable
license delete unit 1 all
write mem
reload

Add the serial number:
enable
hw pid-prom serial 2ax5o2jk68e
hw pid-prom clear-sw-lid

Add the license:
enable
copy tftp license 192.168.2.161 ICX64xx/1-6450-prem.xml unit 1
copy tftp license 192.168.2.161 ICX64xx/2-6450-ports.xml unit 1

show license

write mem
reload

I can see in tftp that the file get accessed, the switch says it writes it, but the licenses always say invalid. I've tried using write mem and various stages, or only on the last stage. No difference.

Any idea how I can get the licenses to stick?

Thanks for the informative OP and docs, and to a lesser degree for this thread (to a lesser degree because I haven't gotten all the way through it yet). A 6450-48P just arrived from eBay this afternoon and appears to be in good condition. And except for one case where I forgot to move a network cable from the management port to one of the general ports, the guide worked flawlessly. The unit is quieter than my Dell 5524P and has double the ports, which makes for a nice upgrade. But you're right about the web interface; it makes the 5524 look polished. Now about that 6610...

Apparently I don't know how to fix it My UPS died today (god I hate APC) which means my Brocade shut down. On booting it up, it lost its licenses again. I get this:

1 Node Lock ICX6450-PREM-LIC-SW H4CKTH3PLN8 Normal Invalid Unlimited 1
2 Node Lock ICX6450-10G-LIC-POD H4CKTH3PLN8 Normal Invalid Unlimited 2

I've run through several times trying to add the licenses again but always end up at the same spot. Here are the last set of commands I've run:

Clear the license:
enable
license delete unit 1 all
write mem
reload

Add the serial number:
enable
hw pid-prom serial 2ax5o2jk68e
hw pid-prom clear-sw-lid
write mem
reload

Add the license:
enable
copy tftp license 192.168.2.161 ICX64xx/1-6450-prem.xml unit 1
copy tftp license 192.168.2.161 ICX64xx/2-6450-ports.xml unit 1

show license

write mem
reload

can you do a teamviewer session so I can poke some things? never seen this happen to a single other person so there's definitely something strange going on

That was my thinking. Let me get something set up so I can get you a teamviewer session. How best to get you the connection info?

I appreciate the offer!

once you have teamviewer running on a desktop with serial console access to the switch just DM me the deets

 

[danb35]

Is it possible to set the switch up with more than one SSH public key? I don't share private keys across my machines, but it'd be nice to be able to SSH into the switch from more than one computer.

Let us know how it goes!

just finished, copy-pasting what I DMd him:


so it looks like it was some corrupted chassis metadata cache under linux, I cleaned out every single file in the temporary filesystem mount, and it's now reading correctly and came up with the right serial and LID:

ICX6450-48P-Router>show pid-prom
-cut-for-privacy-

I had no idea fastiron seems to keep some kind of record of chassis eeprom data on the filesystem, but it definitely seems to. not sure if it was /fast_iron/cvpersistent, /fast_iron/meta_data.bin, or /fast_iron/cvpersistent, but it was definitely one of these that had some bad values in them. clearing them and having fastiron regen them on next boot seems to have totally fixed everything. I suspect maybe one of these was in the middle of getting written to when your first power outage occurred

doing this wiped everything off the switch, so you'll need to reconfigure everything then re-import the licenses - but they should work perfectly now. Just to be sure, I would first pull power from the switch for a minute or so, then repower it. once it's back up, run "show pid-prom" and check that the values are still what I pasted above, and haven't gone blank again - to ensure it's not some cold-boot phenomenon

Much appreciated, Fohdeesha, for helping a guy out on a Sunday evening! I'll throw a little at your liquor fund again, as you saved me from having a bum switch! Many thanks.

Looks like it's only applicable for newer gen switches per Accessing Linux - Fohdeesha Docs 6450, 6650, 7xxx only.

Hopefully won't affect older gens like 6610, FCX, GS...

since those older gens aren't running linux (which is why accessing linux does not work on them ) they're definitely not caching metadata under linux (and if the monolithic fastiron app that boots is, it's entirely wiped out by a primary slot OS reflash)
