if you've only gotten that far you can safely just reboot/unplug the switch and start over. it's only after the "erase" command under "replacing bootloader" that there's no turning back (at least not until you have a new bootloader copied)
Well that's certainly interesting. If you answer each question below we should hopefully be able to fix this quickSo I'm in a bit of a pickle...
I've been following this thread for a while, got a few LB6Ms for a LAB environment, and I'm having an issue with one after flashing it.
I will give step 3 a try tomorrow. As for 1 and 2:Well that's certainly interesting. If you answer each question below we should hopefully be able to fix this quick
third sentence in the guide: "The software itself requires no license or activation to fully function"Did i need a License for the new Firmware? or will it run without entering an License Key?
Regards
Thanks,. just was confused because a License was mentioned here.third sentence in the guide: "The software itself requires no license or activation to fully function"
from: https://www.servethehome.com/turbocharge-the-quanta-lb6m-with-brocade-turboiron/"The Brocade TurboIron 24X is a switch that was EOL’d in early 2017. In terms of hardware, the hardware of the Brocade TurboIron 24X and the Quanta LB6M were nearly identical which means one simply needs a license and the ability to boot the software on the new switch."
So, resetting the MAC fixed it. Looks like whatever was going on was related to a bad/garbage MAC address. All 3 of my switches are flashed and working great so far on the Brocade V8 L3 firmware.Well that's certainly interesting. If you answer each question below we should hopefully be able to fix this quick
1. Do you have other flashed LB6M's plugged in while trying to set up and ping/use this broken LB6M? If so they all have the same mac address if you haven't changed it, which would explain these issues. You say that you couldn't even make contact using the IN band management, which tells me it's some kind of software or network issue
2. Stupid question, but the IP you're assigning the switch is in the same subnet as the tftp server right? and you're sure it's plugged into mgmt port 1, not 2?
3. In the brocade bootloader on the broken switch, run the below command. It should reboot back into the bootloader, now with a fresh valid MAC. Give it an IP and try pinging out to something in the same subnet again. If it still fails, try the t2 ethernet test, then try again.
set ether-address 748e.f8e2.d200
#pull power, then re-power. the "reset" command doesn't work in brocade BL so it can't be used
If it's not a MAC conflict with your other flashed switches, it could potentially be it using an invalid MAC. it tries to pull the chassis MAC address from EEPROM, when it sees the garbage data in there leftover from Quanta it should ignore it, but I guess it's possible that's not happening. The above command would resolve that
4. If all the above fails, try a different ethernet cable of a different length, plugged into a different switch/endpoint if you have one. If you're using a shorter cable, find a longer one, vice versa. If it IS your mgmt port refusing to work with the brocade fw EQ/clock values, changing the impedance/distance on the ethernet side has a slim chance of helping
Try all that and let me know what happens. Worst case it shouldn't come to JTAG. The units can be quite expensive with the right firmware on ebay. Another STH user completely bricked his, he shipped it to me and back so I could JTAG it, I think it cost him $40 total. I'd be willing to do the same for your chassis (if you're in the USA) if we can't get it figured out
Great news! And also interesting, never seen that happen before. I'll add it to the guide under emergency steps.So, resetting the MAC fixed it. Looks like whatever was going on was related to a bad/garbage MAC address. All 3 of my switches are flashed and working great so far on the Brocade V8 L3 firmware.
THANKS for the help!
Yup you're good. You just have an older version of u-bootHi
I run md 0xfff80000 20, I get the different output:
=> md 0xfff80000 20 fff80000: 27051956 552d426f 6f742032 3030392e '..VU-Boot - Pastebin.com
Is it safe to flash?
Quite simple since the switch is already set up as brocade - just use the built in brocade image commands:Oh no. Just when I successfully flashed the v8 image.
So what should we do to move from the v8 to the v7 image?
