Path Analysis App
Path Analysis traces the connection points, including intermediate routers and switches, between the LinkRunner 10G and a destination URL or IP address. You can use Path Analysis to identify issues such as overloaded interfaces, overloaded device resources, and interface errors. It also shows how devices within your network (and off-net devices) are connected to each other along a path.
All switches are pre-discovered through SNMP queries. When the measurement is complete, LR 10G shows the number of hops to the destination device. A maximum of 30 hops can be reported.
NOTE: AllyCare is required to use this application. Your LR 10G must be claimed. Please visit:

Introduction to Path Analysis
Path Analysis combines Layer 3 and Layer 2 measurements.
The Layer 3 measurement combines the classic Layer 3 IP (UDP, ICMP, or TCP) traceroute measurement with a view of the path through the Layer 2 switches.
The Layer 2 measurement discovers switches between the router hops by looking for the routers' MAC addresses in the switch forwarding tables by sending SNMP queries to all discovered switches. The switches found in the path are displayed between the router hops when the measurement finishes.
Path Analysis is most effective when you have configured the Discovery app with SNMP credentials. See SNMP Configuration in the Discovery Settings topic to learn how.
