Cisco 3850 Switch IOS-XE Downgrade 16.x to 3.x

Here's a link where you can find all Cisco Visio stencils/icons.

You can downgrade a Cisco 3850 or 3650 Catalyst switch from IOS-XE 16.x to 3.x. In this case, the Cisco 3850 runs a "newer" 16.6.2 software code.

You can use the "newer" way to upgrade or downgrade using the request platform software package install switch all file flash:<IOS-XE> new auto-copy privileged exec command. In this case I "downgrade" to the old IOS-XE 3.6.7 code. 

Issue a reload command for the new code to take effect.

Cisco Catalyst 9300 IOS-XE Upgrade

My family and I spent our Christmas holiday last year in Bohol, Philippines. The people there were very warm and hospitable. We visited several tourist spots such as the famous Chocolate hills and Sanduguan (Blood Compact) shrine.

This is a Tarsier, which is one of the smallest primate in the world. They're only found in the forests of Southeast Asian islands (Philippines, Indonesia and Malaysia)

We tried the Loay River Cruise and had buffet lunch in Rio Verde floating restaurant. The Loay River Cruise has a more "nature view" (and good food too!) compared to Loboc River Cruise which we've tried many years ago.

This is the new Cisco Catalyst 9300 switch (48-port). The USB slot (type A) is found in front of the chassis (beside the mini USB console port) and it's used for file transfers (for software upgrades).

The console port (RJ-45) and dedicated out-of-band (OOB) management port are found at the rear (left most).

It's has a dual power supply. Power Supply Unit (PSU) slot A is located on the left and slot B is on the right.

Below are the steps in upgrading the IOS-XE software in a Cisco Catalyst 9300 switch:

1. Ensure there's enough flash space for the new IOS-XE file. You can use the install remove inactive privilege exec command to remove old and unused files.

#install remove inactive

 

2. You can use the USB slot to quickly transfer the new software image.
 

copy usbflash0:/cat9k_iosxe.17.06.04.SPA.bin flash:

 

3. Verify the MD5 hash and compare the string output published in the Cisco download website.

verify /md5 flash:cat9k_iosxe.17.06.04.SPA.bin

 

4. Check if the boot variable is set to flash:packages.conf
 

show boot system

 

5. Set the boot variable if it's not yet configured.

boot system flash:packages.conf
 

6. Install/activate the new IOS-XE software, type "yes" to proceed.

install add file flash:cat9k_iosxe.17.06.04.SPA.bin activate commit



7. Verify the new package file and IOS-XE version.

dir flash:*.pkg

show version

 

8. Remove old files.

#install remove inactive

Renumber a Cisco Catalyst 3650 Switch Stack

Here's a link to manually change or renumber a Cisco Catalyst 3650 stack number. This also applies to a Cisco Catalyst 3850 since it has an identical IOS-XE architecture. The switch was removed from a stack and re-purposed as a standalone switch. It remained as logical switch number 4 and the interfaces starts with Gi4/0/x which is quite annoying.
