IOS Update Cisco Catalyst 9200 Stack

VCUGmbH66693 — Fri, 02 Jul 2021 10:04:46 GMT

Hello,

we would like to do a IOS update on a Cisco Catalyst 9200 stack.

We would like to use the "tar" file (with Web management); currently the switch runs on a "bin" firmware without web interface.

I have read some articles which are telling the update has to be done twice, once for each stack member.

As a destination flash1: and flash2: should be used.

When I try to have a look at these filesystems I get back this error message:

C9200-STACK#show flash1:
^
% Invalid input detected at '^' marker.

C9200-STACK#show flash2:
^
% Invalid input detected at '^' marker.

------------

Currently installed is: 17.03.03 CAT9K_LITE_IOSXE

Could you help me out?

Regards

With "classic" IOS all it takes is ONE (1) command and it does everything. One command unpacks the BIN file from the TAR file, does a verification check, writes the boot variable string and erases the old IOS. One command.

New IOS-XE requires a minimum of two commands and a lot of steps, these are:

1. Clean up the flash using the command "install remove inactive"

2. Copy the IOS-XE file into the switch master using the command "copy tftp://filename.bin flash:"

WARNING: The next step will automatically reboot the entire stack

3. Initiate Install Mode using the command "install add file flash:filename.bin activate commit"

4. Stack will reboot by itself.

5. After the stack has finished the reboot, clean up the flash again: install remove inactive

Thanks for your reply.

At step 2 you use filename.bin, shouldn't it be filename.tar ?

The question leads me to believe no one bothered to read the Release Notes. Am I correct?

TAR filename extension no longer "exist" for IOS-XE. Release Notes provide (more) detailed instructions on how to upgrade the firmware.
