As noted in Cisco's documentation, for Cisco SD-WAN edges, you use the command. It consolidates multiple packages into a single .bin file that can be used for upgrading or installing software on the device. After running this command, the consolidated .bin file will be created in the bootflash: directory by default.
Then copy these .pkg files to router flash.
When a failed install occurred on one lab unit due to an unexpected bootloader dependency, the manifest and logs let them quickly trace the issue and update the package precondition to require a minimum bootloader version — demonstrating why precise metadata matters. cisco convert bin to pkg better
In Bundle Mode, the entire OS bundle is loaded into memory, consuming valuable RAM that could be used for routing tables or traffic processing. Install Mode only loads what is necessary, leading to better overall system performance.
Note: The switch will prompt you to reload. Confirm the reload to complete the expansion process. Step 4: Verify the Files and Boot Variable As noted in Cisco's documentation, for Cisco SD-WAN
The .bin file is expanded (extracted) into multiple smaller .pkg files, along with a packages.conf configuration file. The switch only loads the components it needs. Key Advantages of Converting to PKG (Install Mode)
The boot variable must now point directly to flash:packages.conf instead of the old .bin file. Best Practices for a Seamless Transition Then copy these
files are already extracted to the flash memory, allowing the device to start significantly faster. Reduced RAM Consumption
| Pitfall | Consequence | Prevention | |---------|-------------|-------------| | Using tar on Linux/Mac to manually split .bin | Corrupted control structures, boot failure | Always use on-box request command | | Expanding on insufficient flash space | Partial expansion, unbootable system | Ensure free flash ≥ 2× .bin size | | Mixing .bin and .pkg in boot system statements | Unpredictable module loading | Use either all .pkg or all .bin | | Expanding a .bin that already contains .pkg (nested) | Redundant extraction | Check file command output first |
To understand why converting is better, you must look at how each mode handles the switch memory during a boot cycle. Bundle Mode (.bin)
