Environment


  • Palo Alto Networks Panorama device
  • Cisco Plugin for Panorama installed and configured
  • Cisco ACI environment with special characters (non ASCII) in endpoint name/s connected to plugin


Cause


Special characters outside of ASCII range e.g. ö are not supported by Cisco plugin; causing timeout during tag retrieval and processing by plugin.

Resolution


Review the complete list of endpoint names on your ACI environment and ensure that special characters are removed/replaced with ASCII character set.
