Talk about the Cisco 3650 Switch system upgrade that thing!

Speaking of Cisco's switch upgrades, most people think of the following steps:

(1) Upload the system. bin file to the switch via TFTP or FTP

(2) Delete the original. bin file, reboot (or manually set the boot order)

(3) upgrade completed after reboot.

Indeed, 2960, 3560, 3750 and so on switch upgrades can be done through the above points. However, Cisco's 3650 switch upgrade is somewhat different from what it used to be.

Before upgrading, take a look at the dir information in 3650

Here you will find that there is no. bin file.

However, upgrading here still requires the use of the. bin file, as the upgrade files you download from the Cisco Web site are. Bin. Let's take a look at the specific steps:

1, download the necessary upgrade files from the website, the file extension is. bin.

2. Upload to the switch via TFTP, as follows:

switch#copy tftp://10.0.0.2/cat3k_caa-universalk9.16.03.06.spa.bin Flash:
Destination filename [cat3k_caa-universalk9.16.03.06.spa.bin]?

[OK-537577577 bytes]
537577577 bytes copied in 211.316 secs (2543951 bytes/sec)

3, unlike the previous upgrade is here, execute the following command to install

switch#Request Platform software package Install switch all file Flash:cat3k_caa-universalk9.16.03.06.spa.bin

In fact, to upgrade here to complete the half, because the above hint:New software will load on reboot. This means that the restart is initiated with the new system.

We then use Dir to see:

The above shows you can see that the new version of the system is installed in Flash, but the old version of the system is still in. Then how to remove the old version of the system to release the system space it? Let's go down.

4. Restart the switch and the switch will start with a new version of the system after rebooting

The above display has been started from 16.3.6, and then we can release the system space by the following command:

Then with the Dir view will find that the old version of the system has been deleted, then 3650 has been upgraded to complete.

Description: It's a good idea to check the official documentation before upgrading the system, but when I look at the official documentation for the 3650 upgrade, I found that the fourth step in the document was to release the system space before uploading the file, but if you did follow that, you would find that freeing up space would be impossible! Why not, leave you to think, but in fact the answer is in this article ...
