Software File Management Using Command Sets Consolidated Packages and SubPackages Management Table 10 Advantages and Disadvantages of Running Individual subPackages and Consolidated Packages Approach Advantages Disadvantages Individual and optional subpackages Note This method is required if you need to install any optional subpackages for your system. • Optimizes memory usage, allowing for faster boot times and increased traffic loads. • Multiple software subpackages more difficult to manage. • Cannot be booted from TFTP or any other network server. If you are going to use the individual subpackage boot method, each individual subpackage file must be placed in the bootflash: directory. • Individual and optional subpackage files and the provisioning file must be stored in bootflash:. Consolidated Package • Easier management. Only have to manage one file instead of many files. • A consolidated package file can be stored in bootflash:, on a USB Flash disk, or on any TFTP or other network server. • Slower boot times and lessened maximum system scalability because the larger image must be processed at all times. Software File Management Using Command Sets Software files can be managed on the Cisco ASR 1000 Series Routers using three distinct command sets. This section provides overviews of the following command sets: • The request platform Command Set, page 4 • The copy Command, page 5 • The issu Command Set, page 5 The request platform Command Set The request platform software package command is part of the larger request platform command set being introduced on the Cisco ASR 1000 Series Routers. For additional information on each request platform command and the options available with each command, see the Cisco IOS Configuration Fundamentals Command Reference. The request platform software package command, which can be used to upgrade individual subpackages and a complete consolidated package, is used to upgrade software on the Cisco ASR 1000 Series Routers. Notably, the request platform software package command is the recommended way of performing an individual subpackage upgrade, and also provides the only method of no-downtime upgrades of individual subpackages on the router when the router is running individual subpackages.
