Hi Guys,

I bought a while back one of these lb4m switches. I have good firmware and UI as seen below.

(Switching) #show version

Switch: 1

System Description............................. FASTPATH Switching
Machine Type................................... LB4G 48x1G 2x10G
Machine Model.................................. LB4M
Serial Number.................................. QTFCPW9510066
FRU Number..................................... 1
Part Number.................................... BCM56514
Maintenance Level.............................. A
Manufacturer................................... 0xbc00
Burned In MAC Address.......................... 00:26:9E:1E:A3:EF
Software Version............................... 1.0.2.17
Operating System............................... VxWorks5.5.1
Network Processing Device...................... BCM56514_A0

my question is mostly about the two 10gbit spf+ ports and GBIC's on my network cards.

on my LB4M I have two Finisar FTLX8571D3BNL-E5 SPF+
on my server Dell R510 I have 1 10gbe card with JDSU PLRXXL-SC-S43-C1 and another with Finisar FLLX8511D3-IT.

Both 10gbe ports on the LM4B have spanning tree as edge ports since I am connecting them directly to the server. Issue is link is down using either Ethernet card. if I create a loop using fiber cable and plugin port 49 to port 50, both come up, so this tell me sfp+ on both are working but they do not work when I plug them into the GBIC's on the server.

I tested the both cards on the server connecting directly to another server and they work.

Any help or hints would be greatly appreciated.

Thanks in advance..

Appears you have a XFP based card yet the switch is SFP+. Given that it likely wasn't an issue between 2 cards by direct attach.
Keep an eye on STH likely be deals on the single/dual SFP+ cards so you could retire the XFP cards.

Yep, that would make Perfect sense. Thank you..

I'd posted a while back about getting sFlow working on this switch.
It's not difficult to setup and can help one visualize various types of traffic.
First, go to Inmon.com and download sFlowTrend which is available for free.
Next, run through the installer, start the client, and setup sFlow on your switch.

If configuring sFlow through the switch's web interface, do the following:
Go to "System -> sFlow -> Receiver configuration"
Receiver Index: 1
Receiver Timeout: 4294967295
Receiver address: (IP of system where sFlowTrend is installed)
Receiver port: 6343 (default, make sure to open this UDP port on your system's firewall)

Lastly, go to "System -> sFlow -> Poller configuration" and add your sampler data sources.
Add any slot/ports that you wish to monitor, set your receiver index (1), and a polling interval (2 seconds).
If all was done well, the sFlowTrend Dashboard should indicate "Monitoring one switch/router" in the lower-left corner.

I've attached an image showing a simple traffic graph of an interface.
Let me know if anyone else finds this to be neat. Enjoy!

Hi,

Anybody using LB4M switch LACP/Port Channel feature with Linux? What is the correct settings? I tried everything, but i can't reach 2 GBITs (from multiple server which are 1GBits).

Thanks for this , it is pretty cool. I think will be giving this a go when I get my network up and running. Need to remove the Dell z9000 and put in the lb6m and wire them up the the lb4ms

As far as I know that is the most up to date firmware. The current firmware I have on file (as I save any firmware I find) is 5.13.12.14 Routing Enabled 1.0.2.17.
I'd attach the file but it seems the 9MB file is to large to attach to the forum.
If you really want it I'll post it somewhere else and link it.

I mix XFP broadcom based cards with SFP+ based switches and it seems to work for me.

I just picked up one of these switches on eBay and with help of this great thread I was able to flash the routing firmware, set up LACP, though I have a CHELSIO 10G Dual Port card on order. I am a bit struggling setting up VLANs and VLAN routing but guess will figure this out later today with some more familiarizing with the CLI.

I just picked up a LB4 (no M). Is the firmware for the LB4M compatible with it? It has 4 CX4 ports on the back and no swappable power supplies.

The web interface works as well and it has SSH.

I have eyed around the thread and saw how it is a choice of have working webui or ssh? Also it has working SFTP ability to upload/download things.

If anyone wants this firmware I can upload it.

The info is all here in the thread. I just flashed mine to the 5.x firmware and then figured out how to enable all the ports. This thread has all the info you need.

I have one of these running .14 code. How do I do the equivalent of 'show interface', I haven't yet found a 'show' command to tell me
if an interface is up or down.

Thanks,
Joe

PS: After removing the top cover, it says 'AMAZON' on the motherboard. Maybe Quanta did a special run of these for Amazon?

If you plug in the management port, does it pull an IP? Mine did, then telnet in, do an "enable" command, then you can run the various other commands in this thread
