NetBox plugin to manage software for your Cisco devices in following aspects:

• software repository (download does not work after Gunicorn was changed to nginx-unit, trying to manage with it)
• assign target (golden) image on created Device Types
• get software version compliance report for every device in Excel format
• scheduled upload golden image on devices
• scheduled reload devices with golden image

1. Compatible with NetBox 2.9 and higher versions only.
2. Plugin works with standalone IOS/IOS-XE boxes only. No Stacks/VSS/StackWiseVirtual at present.
3. Plugin operates with software version only, and does not consider feature set (lanlite vs lanbase, K9 vs NPE).
4. Test in your local sandbox, do not jump to production network.
5. Use this plugin on production network at one's own risk with take responsibility for any potential outages due to reload of devices.

Select *.bin file, specify expected MD5 (from cisco site) and verbose version. Plugin calculates MD5 when file uploading and result should matches with entered MD5, otherwise MD5 will be redded.

Assigned Image/Version for all created DeviceTypes with upgrade progress for particular DeviceType. "Export" button provides detailed Excel report.

provides information about Target/Current versions (green = match, yellow = upgrade is required)

• Select job type:
  • upload (transfer golden image to the box)
  • upgrade (reload with golden image w/o transfer)
• select time to start or set "Start Now". Time is based on NetBox TimeZone, not your browser/hostPC.
• select MW duration. All tasks will be skipped after this time (countdown starts from scheduled time, not from time of creation tasks)

List of all scheduled/completed tasks.

Tasks with Running status can be deleted in admin view only.

Plugin has acknowledgment logic to try to prevent mass outage. ACK flag become True only in case of getting expected result. In case of any unknown error/traceback job will be finished with ACK=False. Any new job checks number of non-ACK and can be skpped if this number crossed threshold. ACK flag can be changed manually by clicking on "V" or "X".

Detailed information about task and execution log.

Instruction below describes installation for Docker-compose instance of NetBox.

For bare-metal setup pip can be used for installation. But some changes (ftp/redis etc) will be requared anyway.

pip install netbox-plugin-software-manager

cd {{ your-netbox-locaton }}
git clone https://github.com/alsigna/netbox-software-manager.git
cd netbox-software-manager
docker build -t netbox-plugin .

Why FTP? Originally scp was used to transfer files, but based on experience, FTP is much faster.

HTTP was added in 0.0.3, But FTP_USERNAME in configuration still required as it used as folder name for IOS upload

cd ftp
docker build -t ftp_for_netbox .
cd ../../

or

cd http
docker build -t http_for_netbox .
cd ../../
