Recover Cisco 9200 switch from firmware loss

Leave a comment Posted by on February 11, 2022

recently I had an issue where the firmware on a 9200 switch was corrupted. This can help during an upgrade, or removal, etc.

After a reboot the switch came up to rom monitor mode, no biggie I thought- just copy the firmware from USB over to flash and install. This did not work, I continued to get error: “Unsupported destination device/filesystem.” see below-

switch: copy usbflash0:cat9k_lite_iosxe.17.03.04b.SPA.bin flash
Unsupported destination device/filesystem.

I then booted from the USB image and installed the system that way. My steps were:

  • Frist check the file on USB and make sure its there/get the name.

switch: dir usbflash0:

Attributes Size Name

D-HS- 0 System Volume Information
—-A 482856473 cat9k_lite_iosxe.17.03.04b.SPA.bin

Then set my switch to boot to this value :

switch: boot usbflash0:cat9k_lite_iosxe.17.03.04b.SPA.bin

This fully loaded up the switch, and came up at a default setup screen. Once there I copied over the file VIA TFTP to flash. The device would not recognize the USB drive now (Probably cause I booted from it). Once copied to flash, I just installed normally, and rebooted.

Switch# install add file flash:/cat9k_lite_iosxe.17.03.04b.SPA.bin activate commit

This operation requires a reload of the system. Do you want to proceed?
Please confirm you have changed boot config to flash:packages.conf [y/n]y

IMPORTANT!!!

Next you have to change the boot config – or else it will go back to rom monitor.

config t

boot system flash:packages.conf

exit

wr mem

That’s it!

Ruckus ICX switching – Displaying files on USB or flash

Leave a comment Posted by on September 30, 2021

I needed to update the firmware on a Ruckus ICX 7150, but could not remember the file name of the firmware I was updating. I looked through the commands for a dir: flash, or dir:usb and really couldn’t find much. After some googling didn’t come up with anything either.

To display the the files use the “Show files {Device}” for example to show files on flash “show files flash”

ICX7150-24P Switch#show files?
ASCII string dir name


ICX7150-24P Switch#show files flash

Type Size Name

F 33554432 primary
F 32539748 secondary
F 256 primary.sig
F 162204 poe-fw
F 1576 $$ssh8rsahost.key
F 256 secondary.sig

66258472 bytes 6 File(s) in FI root

1135529984 bytes free in FI root

Below show getting the files on the USB drive.

Dell N2248-ON firmware restore from ONIE Recovery

Leave a comment Posted by on May 3, 2021

I have been working a lot with the Dell N-series over last few years, and now the N2248-ON which can run OS10 as well as the default OS6. We upgraded firmware to the latest 6.6.3.10 and all seemed to go well. Somehow it did not and hosed both primary/secondary firmware. The device was boot looping – the only option was to drop into ONIE Recovery and re-install the firmware. Here are the steps I used:

The ONIE recovery area runs a version of Linux. First check out your NIC to make sure it finds it:

ONIE:/ # ifconfig
eth0 Link encap:Ethernet HWaddr 8C:47:BE:97:B5:0F
inet6 addr: fe80::8e47:beff:fe97:b50f/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:67 errors:0 dropped:0 overruns:0 frame:0
TX packets:13 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:6904 (6.7 KiB) TX bytes:1198 (1.1 KiB)
Memory:dfe00000-dfe7ffff

Great! Eth0 is found, but of course link status is down. Eth0 is the out of band management interface. We should be able to set an IP address on the interface and install firmware VIA TFTP or USB.

First I will setup and IP that can communicate with my laptop :

ifconfig eth0 192.168.1.100 netmask 255.255.255.0

ONIE:/ # ifconfig
eth0 Link encap:Ethernet HWaddr 8C:47:BE:97:B5:0F
inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::8e47:beff:fe97:b50f/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:108 errors:0 dropped:0 overruns:0 frame:0
TX packets:49 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:10874 (10.6 KiB) TX bytes:7658 (7.4 KiB)
Memory:dfe00000-dfe7ffff

Perfect! My laptop is 192.168.1.99 – and connected directly to the out of band MGMT port.

Next we will TFTP the file up. This file is located in the software archive you download from Dell – Its located in the
“Otherfiles” folder. In this case the file name is onie-installer-x86_64-dellemc_n22xx_6.6.3.10. Next I put this on my TFTP server and we can start the install.

First lets turn off the ONIE-Discovery attempts with the onie-stop command.

Now lets upgrade – Run:

onie-nos-install tftp://192.168.1.99/onie-installer-x86_64-dellemc_n22x
x_6.6.3.10

The onie-nos-install will install the OS back to the device. The firmware took a few minutes to install, with about 4 reboots I think – it was all automatic.

Now lets see if the switch was updated with the “show version” command.

All is good!
