Confirm enough space and verify image checksum (see above).

Stage image in flash and keep existing image as rollback option.

The 15.0(2)SE train is one of the most stable and mature releases for the Catalyst 3560 series. Here is why administrators specifically search for the .se11 release:

This handbook covers practical, concise guidance for obtaining, verifying, deploying, and troubleshooting the Cisco IOS image named C3560-ipservicesk9-mz.150-2.SE11.bin for Catalyst 3560 series switches. It assumes you are managing Catalyst 3560 family hardware and need a dynamic, actionable reference for life-cycle tasks (download, validate, install, rollback, config considerations, and common issues).

Step 1: Copy the Image to the Switch

Using TFTP:

Switch# copy tftp: flash:
Address or name of remote host [ ]? 192.168.1.100
Source filename [ ]? c3560-ipservicesk9-mz.150-2.se11.bin
Destination filename [ ]? c3560-ipservicesk9-mz.150-2.se11.bin

Using USB (if available):

Switch# copy usbflash0:c3560-ipservicesk9-mz.150-2.se11.bin flash:

Step 2: Verify the File Integrity Compare the file size and MD5 checksum. Cisco provides the MD5 on their download page.

Switch# verify /md5 flash:c3560-ipservicesk9-mz.150-2.se11.bin

The output should match Cisco’s official hash exactly. If it doesn’t, do not proceed. C3560-ipservicesk9-mz.150-2.se11.bin Download

Step 3: Set the Boot Variable Tell the switch which image to load on the next restart.

Switch(config)# boot system switch all flash:c3560-ipservicesk9-mz.150-2.se11.bin
Switch(config)# exit

Step 4: Save and Reload

Switch# write memory
Switch# reload

Confirm the reload. The switch will take 2–4 minutes to boot. Confirm enough space and verify image checksum (see above)

Step 5: Verify the Upgrade After the switch reloads, log in and run:

Switch# show version

Look for:

Even without an active contract, if you have previously registered the device’s serial number and have a legacy entitlement, the software may appear in your "Download History" or "My Devices" section. Verify boot variable:

Switch# configure terminal
Switch(config)# boot system flash:c3560-ipservicesk9-mz.150-2.se11.bin
Switch(config)# exit
Switch# write memory
