Chapter 6 Managing Cisco IOS XR Software Packages
SMUs are not an alternative to maintenance releases. They provide quick resolution of immediate issues.
All bugs fixed by SMUs are integrated into the maintenance releases. The format for single package
SMU is:
platform-package_type-major.minor.maintenance.ddts.pie
The filename components are described in

Description
Identifies the platform for which the software
package is designed. For packages designed for
CRS-1 Routers, the platform designation is either
"hfr" or "CRS-1."
Identifies a specific composite package.
The composite name is a name or number that
•
is unique to the SMU.
Identifies a Distributed Defect Tracking System
(DDTS) number that describes the problem this
SMU addresses.
DDTS is the method used to track known
Note
bugs and the resolutions or workarounds
for those issues.
Identifies the type of package the file supports
(package-type applies only to single package
PIEs). Package types include:
• fwdg for the Forwarding package
lc for the Linecard package
•
mcast for the Multicast package
•
mgbl for the Manageability package
•
mpls for the MPLS package
•
k9sec for the Security package
•
rout for the Routing package
•
Identifies the major release of this package.
A major release occurs when there is a major
•
architectural change to the product (for
example, a major new capability is
introduced).
All packages operating on the router must be
•
at the same major release level.
A major release is the least frequent release
•
and may require a router reboot.
