hi guys,
Sorry that i ask so dumb, but i doesnt found any solution in this thread, or on other forums.

I just want to connect One Quanta lb4m on port 0/49 and 0/50 in an LACP Trunk to another quanta lb4m.
Can anyone jsut explain me how i can do that?

Regards

I'm genuinely struggling with creating a LAG also.

Im trying to create a LAG between ports 1-4 to my PfSense router but for the life of me can't make it happen (granted I only spent a few hours last night trying) but I'm near giving up already haha.

edit: Was pfSense all along.. -_-

Hey guys,
I've been trying to connect to the web UI but with no luck. I'm connected to the CLI through a console cable and while I can find the IP address for the service port it is set to 0.0.0.0. Looking further, DHCP is not enabled. Here is a screenshot of the service port settingsupload_2017-12-2_21-17-2.png

Anybody know how to set a static IP address/enable DHCP for the serviceport?

My ultimate goal is to gain access to the web UI so if I'm going about it the wrong way, please tell me. I have tried the ip of the switch but when typed into a web browser, it cannot connect.

It took me awhile, but I was able to figure it out. Here are the steps I had to go through to gain access to the web UI: https://goo.gl/pf2bbD & https://goo.gl/NyiBJ1 OR https://goo.gl/pb3dZt (I did not try this one)

{} means comments.

{you will need a console cable. Putty under serial}
1. login
username: admin
password: {blank}

2. update firmware to latest version.
NOTE: I had to set up a TFTP server to host firmware from personal
computer TFTPD32 : an opensource IPv6 ready TFTP server/service for windows : TFTP server
Firmware: Index of /~jared/lb4m
enable
show bootvar
copy tftp://172.16.6.10/lb4m.5.13.12.14.bin backup{or image2}
boot system backup
reload

3. enable the ports. This version by default disables the ports
username: admin
password: {blank}
enable
config
{while morePorts:}
interface 0/{port number}
no shutdown
exit
{port number += 1} {this goes up to 50 including console and management/service port}​
exit

4. set IP addresses
network protocol none {sets to static}
network parms 192.168.1.15 255.255.255.0 192.168.1.1
serviceport protocol none
serviceport ip 192.168.2.15 255.255.255.0 {Note that service port is on different network}

5. FINALLY connecting to the web ui
plug in ethernet cable to the management/service port
set a static ip of 192.168.2.xxx 255.255.255.0 192.168.2.1
open webbrowser and connect to 192.168.2.15
username: admin
password: {blank}


Hope this helps!

Does somebody tried/testing with alternative firmware?
The possible compatible hardware - BCM56514 (Firebolt2-A0) - switches:
Code:
HPE 5500-24G-4SFP
HPE 5500-48G-4SFP
Enterasys B5K125-48
Enterasys B5K125-24p2
ExtremeNetworks 220-24t-10GE2
ExtremeNetworks 220-48t-10GE4
The HP image has UBOOT loader inside, now I have some spare time to have fun with her :)

It also has to support the Freescale MPC8541E cpu.

Hi, yes the problem is:
-Quanta: POWERPC arch
-HPE: MIPS arch

but there is a 3rd option, the Juniper MX80 has the same architecture (PowerQUICC III), so I think the some older version of JUNOS is can be used on this platform, but there is an another problem: flash memory size.

There's no way you're gunna load MX junOS on a quanta. the MX series uses a very different processor (the powerquicc 3 line is huge). The MPC8572 in the mx80 has 64 bit instruction set support to start with, which is missing on the quanta. Also has pci-e bus, ddr2 support, 2 cores instead of 1, etc

There are 32bit and 64bit images for that platform (as I know the mainline is the 32bit images) , so i think the lack of 64 bit instructions sets are no problem.

The problem is the writable storage/flash size, it requires at least 1GB storage.
First, it necesseary to have an external storage connection (example: desolder the flash-chip and make NAND Flash / CF bridge).

This will be the next year's project :)

(Finally) ordered one for my growing setup. Will be modding it for relatively low noise operation.

That said, this uses a fairly standard Delta 12v 300w power supply, which is not even that efficient. I wonder if I can mod it, and feed it 12v directly from a more efficient power supply... :) It's a switch...should be fairly easy.

For anyone with a non operational LB4M switch, Codewarrior Ethernet TAP(PowerTAP Pro) with the PPC JTAG probe works to program these switches.

  • Use CodeWarrior 8.8 for PowerPC Architecture (eval version works)
  • Flash config is s29gl256p 16x16x1.
  • Use target initialization config at: \CodeWarrior PA V8.8\PowerPC_EABI_Support\Initialization_Files\PQ3\8540EVAL_init.cfg
  • Erase 0xFFF00000 to 0xFFFFFFFF
  • Write at offset 0xFFF00000
I've included a copy of the original bootloader.

Great info! Should work with lb6m/lb8/delta 7024/dell 8024 as well since they're all the same PPC family. (different mpc8XXX models will probably need different matching init configs loaded I would imagine)

Just wish they weren't $250 used on a good day!

BDI2000 also works. Most of the ebay listings don't have a power cord, but it works off usb's 5 volts, just don't reverse the polarity. As for the firmware, ask Abatron.

Starting to trace the power supply pins and power delivery.

I have this wild idea of running 12v directly to this switch, with no PSU attached. I already have a 12v distribution panel in my rack, that is powered by HP platinum 1200w power supplies (in redundant mode). This powers a few low power motherboards/systems which have pico-psus in them.

Given the PSU specs for this, the PSU just delivers 12v to the board, with a number of "sense" pins for all sorts of things. With some fan mods and running 12v directly to it...hmm...

Hello everyone,

I recently received 4 of these Quanta LB4M switches to play with.

I am currently struggling with RADIUS configuration.
I was able to put my radius server as primary, and I am able to log in with my radius account. But I never have admin privileges, i. e., when I enter the switch, I cannot type the "enable" command :

Code:
(valerian) >?

help                     Display help for various special keys.
logout                   Exit this session. Any unsaved changes are lost.
passwd                   Change an existing user's password.
ping                     Send ICMP echo packets to a specified IP address.
quit                     Exit this session. Any unsaved changes are lost.
show                     Display Switch Options and Settings.
telnet                   Telnet to a remote host.
Here is my current configuration. I have tried the option "users default enable" :

Code:
!Current Configuration:
!
!System Description "FASTPATH Switching"
!System Software Version "1.0.3.2"
!System Up Time          "0 days 1 hrs 55 mins 11 secs"
!Additional Packages     FASTPATH QOS
!Current SNTP Synchronized Time: Not Synchronized
!
set prompt "valerian"
enable passwd encrypted XXXXXXXXXX
vlan database
exit
ip http secure-server
ip http secure-protocol SSL3
ip ssh server enable
ip ssh protocol 2
configure
!
ip name server 172.23.0.229
users passwd "admin" encrypted XXXXXXXXXXXX
aaa authentication login "mylist" radius local
aaa authentication enable "my list" enable
users default login "mylist"
users default enable "mylist"
radius server host auth 172.23.0.235
radius server key auth 172.23.0.235 encrypted XXXXXXXXXXXXX
radius server primary 172.23.0.235
lineconfig
no transport input telnet
exit
spanning-tree configuration name "XX-XX-XX-XX-XX-XX"
exit
Any idea how I can allow non-configured users to have admin privileges ?

Thanks.
