SMUs for each release are individually downloadable from Cisco.com, whereas the bootable files and optional PIEs come in the form of a tarball.
SMUs are release specific. If an issue affects multiple platforms or releases, an SMU will be separately built for each release and each platform depending on the mission-critical need.
A CRS-1 SMU cannot be applied to a different platform, and vice versa.
SMUs provide software fixes for critical network-down and qualification-blocking issues. Therefore, every software defect will not have a corresponding SMU.
