Cisco PathTracer Overview
Cisco PathTracer enables you to launch end-to-end route traces and view related performance
information for Layer 1, Layer 2, and Layer 3 traffic. Upon receiving a path's start and endpoint,
Cisco PathTracer visually traces the route through the network. For example , i n an ATM network
environment, Cisco PathTracer identifies all information regarding the connection of a subscriber to a
provider, including all ATM PVCs, ATM switching tables, ATM class of service (CoS) definitions,
IP-related information, and so on.
You can also use Cisco PathTracer to:
• Trace paths using IPv4, IPv6, or both IPv4 and IPv6 addresses for th e sou rc e an d des tina tion.
• Trace a hypothetical Ethernet frame from a VLAN interface to a specified MAC address.
• Trace a hypothetical Ethernet frame from an Ethernet interface to a specified MAC address within
a specific VLAN identifier.
