After reboot, run show version to confirm it is running the new image. 6. Troubleshooting

switch# copy tftp: flash: Address or name of remote host []? Source filename []? c3560-ipservicesk9-mz.150-2.SE11.bin Destination filename [c3560-ipservicesk9-mz.150-2.SE11.bin]? Use code with caution. Once the transfer is complete, verify the file: After reboot, run show version to confirm it
After obtaining the file from any source, you must verify its checksums. Official Cisco SHA256 (from Cisco's published data for this release): Source filename []
