Tips for better results

  • ·Include the full syslog line including timestamp, facility, and severity — do not truncate it
  • ·If you have multiple related errors, paste them all together
  • ·Mention the OS version if you know it — some errors behave differently across versions
  • ·For Cisco IOS XR: include the node location (e.g. 0/RP0/CPU0) if present in the syslog
  • ·For Juniper: include the routing-engine (RE0/RE1) and daemon name from the syslog
  • ·For Palo Alto: include the log type (threat, traffic, system, config) for better analysis
  • ·For FortiOS: include the VDOM name if multi-VDOM is enabled
