ztp-watcher's Issues
IOS based on model
Not hard - an snmp call and a dictionary - you could likely accomplish this better than I can. An optional "copy runn start" might also be useful. Please let me know if you have time to look into this, if not, I shall cobble away at it. Thank you for your time.
ModuleNotFoundError: No module named 'yaml'
The service ztp-watcher.service seems to fail with this error.

UnboundLocalError: local variable 'ipaddr' referenced before assignment
Hello,
I followed your tutorial and installed ZTP-Watcher including all dependencies (some not listed in your guide) successfully.
In FreeZTP, I created custom keystore values and installed your script including all needed dependencies successfully.
The ZTP-Watcher service is running successfully, but when a merged configuration is discovered the script stops with an error message:
Oct 13 13:28:07 ztp bash[799]: self.run()
Oct 13 13:28:07 ztp bash[799]: File "/usr/local/lib/python3.8/dist-packages/watchdog/observers/api.py", line 199, in run

Oct 13 13:28:07 ztp bash[799]: UnboundLocalError: local variable 'ipaddr' referenced before assignment
Assigning a static IP in VLAN 1 via my merged template didn't change the behavior.
I don't know where the error message is coming from, could this be a reference issue in the script?
The merged configuration is saved at /etc/ztp/logs/merged with following name:
C3650_10.6.13.240_SERIAL_merged.cfg
It would be nice to get some help.
Best regards
