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

[richtj99]

yes these are just debug variables that aren't even used unless you go in and enable remote GDB debugging among other things, they are normal to be populated from factory

Sorry - I am late to the party - Thank you!

Quick question. In the 6610, can the non-PoE PSUs be used in a PoE version of the switch?

Obviously only like 60-90 watts could be used for PoE since it's 250W and not 1000W. Or maybe no PoE at all.

Just wondering if there would be errors or anything to prevent the switch from booting.

The nonpoe psus can be used but poe will be completely nonfunctional, the poe system uses a 54v power rail that the nonpoe psus do not have

Won't make any change for battery lifespan

But it will impact the projected battery lifespan in the event of a blackout. Or if someone thinks that "there's plenty of power available" and proceeds to connect other things to the UPS it could cause an overload when the mains will go effectively out, causing a cascade failure also of the backup power.

Sorry if this was already asked but I tried to search and haven't found a answer, do the 10gb SFP+ ports on the ICX7150-12P support a RJ45 10gb SFP+?

Yes, and they are called 10GBase-T when searching.

Thank you! I was worried since I saw one Ruckus compatibility guide that specifically said 7150s couldnt do copper, but it was THEIR copper adapter

Link to the guide?

https://www.commscope.com/globalassets/digizuite/61722-ds-ethernet-optics-family.pdf specifically their "10G-SFPP-TX-A" isnt shown as compatible with the 7150. I was hoping someone here had first hand experience.

Not really, no. However, the Dell ones linked to on the front page are still $95 each.

It's just the latency factor and remaining 100% fiber everywhere - for the hell of it. I mean, I ran a 75ft fiber just to connect my little-used desktop on the other side of the house - as I don't have any Cat6a cables, ends, etc. Everything is fiber through the switches and DMZ, all the way to the pfsense router via IOMMU passthrough - and then goes to RJ45 to the ISP (ugh). Pinging in gaming servers are still quiet low!

But you are right. Those DACs are a bit cheaper at about 1/2 the cost. And again, there are $35 ones in China... But then again, it's China.

I have some Brocade brand breakout cables that I'm willing to sell. I had a for sale thread with them a while ago. The FC ones are brand new and I have DAC's that are used. FC is 10m and DAC is 5m. PM me for price since this isn't a FS thread or create a WTB thread and I'll respond there with prices.

 

[Jason Antes]

I also have QSFP stacking cables.

I know pfSense can't be used for DHCP when using the Brocade ICX-6610 as a layer 3 switch with VLANs.

Can anyone tell me if VyOS is capable of handling DHCP in a similar setup?

According to the guide, no:

DHCP Server — VyOS 1.5.x (circinus) documentation

docs.vyos.io

It's a good question, as I'll run into the same issue when I setup my DMZ in the future.

I ran a UPS test this weekend and my 6610 Rev A PoE power supplies won't run on simulated sine wave power. I have the PSUs plugged into a pair of Cyberpower CP1500AVR units. Anyone here have the same experience? Do Rev B or C run on simulated sine wave?

I've run single and dual 6610 POE's with dual rev a and dual rev b on cyberpower CP1500AVR 's (they are cheap)...
any slight power fluctuation that trips the UPS and the switches would crash and reboot.
My recollection is that the switches were more tolerant of minor power fluctuations off the CP UPS than on

Moved to an Eaton 5PX2200 and the switches are rock solid.

It is generally not advisable to run Switching Mode Power Supplies on non-pure sine wave power, especially modern ones with Active PFC. You're basically rolling a dice with that. Might work, might not.

I have the non-poe version of 6610 with Rev A. It is running fine with an APC BX1500M, which is not sine wave. Am I doing something bad to the switch or the UPS?

FWIW, the best option for that type of setup (e.g., VyOS, pfsense) is DHCP option 121. You can either explicitly add a route to one different VLAN subnet via your router (e.g. 192.168.1.0/24 via the ve on your Brocade) or to an entire range, depending on the address ranges you’re using (e.g., 192.168.0.0/16 via the ICX).

With your internet-facing router set as the default gateway and on the same subnet, your devices will know it can reach the gateway directly, avoiding any asymmetrical routing issues.

I'm trying to figure this out, could you give more information/details/steps to DHCP option 121? I'm trying to find more information about it.

Alternatively, which may not be the best idea as I haven't done it yet, I was thinking I could tag all the VLANs on a trunk that I want DHCP for within the switch, and connect it to the router on another dedicated port. On the router, I could have the DHCP server(s) bind to an IP/bridge within those VLANs which are tagged on that interface.

The idea keeps InterVLAN routing on the switch by keeping the gateway on the switch's `ve`, but would route those DHCP helper-ip requests to the actual DHCP server IP address - on the same VLAN (or perhaps the DHCP server could actually reach the broadcasts of that VLAN).

I don't know if that would work, because the router would have a different default route.

Default gateway: were do I send my packets
Default route: were do I send some other guys packets and my own packets

So, DHCP option 121 tells some device what to do with other guys packets

*I* like the way this guy explains things, ymmv.
