Strictly speaking, Cisco’s official naming convention does not include an upd suffix. However, in internal logs, community forums, and FTP directory notes, upd is often used to indicate that the .bin file is the original FCS (First Customer Ship) but rather a subsequent update containing bug fixes, security patches, and hardware compatibility tweaks. If you see c3560ipservicesk9mz1502se11bin referenced with upd , treat it as the recommended refresh of the SE11 release.
(Protocol Independent Multicast) in sparse, dense, and sparse-dense modes, as well as tunneling. Virtualization (VRF-Lite):
If your current image is older than 15.0(2)SE6, the upd will be a transformative upgrade. If you are running SE10, the differences are negligible except for security.
As a late-stage maintenance release, SE11 is considered highly stable for production environments that do not yet require a hardware refresh to the Catalyst 9000 series. Conclusion
