Cisco Catalyst – Upgrading IOS (via USB)

KB ID 0001056 Dtd 22/04/15

Problem

Had a stack of 3560-X Switches to update today, and when I went looking for the notes I used last time, I could not find them. So This time I took the time to document the procedure.

Solution

Now I could load in the IOS image form TFTP like this, but last time I did this I used a spare USB drive and the image ‘tar’ file, and found it a lot less hassle.

1. Make sure you have formatted your dive at FAT32, download you image file to it and put it in the switch.

usb update cisco

At console you should see something like this;

Apr 22 13:13:18.466: %USBFLASH-5-CHANGE: usbflash0 has been inserted!

2. Update the switch like so;

  Old image will be deleted before download.

3. At this point when the switch reloads, it will take a long time to boot as it performs a lot of updates and code rewrites when it restarts.

Upgrading The Catalyst Service Module

These switches have a 10Gb Service module in them that also needs updating, once the switch reboots you will have to wait a few minutes before the service module boots as well, if you don’t wait then you will see this;

Petes-Switch#show switch service-modules
Switch/Stack supports service module CPU version: 03.00.76
                          Temperature                     CPU
Petes-Switch#  H/W Status       (CPU/FPGA)      CPU Link      Version
-----------------------------------------------------------------
 1             OK               48C/43C         notconnected  N/A

You may also see an error like this (I’ve blogged this before).

Mar 30 01:29:55.128: POST: Macsec Uplink Loopback Tests : Passed Decryption Mode
Mar 30 01:29:57.594: POST: Macsec Uplink Loopback Tests : End

 version. Please update the software. Module is in pass-thru mode.
Petes-Switch#show switch service-modules

                          Temperature                     CPU

 1             OK               54C/54C         ver-mismatch  03.00.41

Or it may simply look like this;

Mar 30 01:32:29.403: %PLATFORM_SM10G-6-LINK_UP: The FRULink 10G Service Module (C3KX-SM-10G)
communication has been established.
Petes-Switch#
Petes-Switch#show switch service-modules

                          Temperature                     CPU
Petes-Switch#  H/W Status       (CPU/FPGA)      CPU Link      Version

 1             OK               50C/48C         connected     03.00.76

To perform the upgrade, you will need a matching image for the service module.
