Abstract
Improved debugging capabilities for network packet path tracing. Embodiments trace both the control and data planes. During control plane operations each switch appends its identity to the payload, providing a full trace of the control plan path. SNMP Trap commands containing the forward path payload are provided back at each hop. The data plane is monitored by setting traps along the control plane path, with SNMP Trap commands at each hop being provided that indicate a given switch has been used.
