Path Settings
Contents
Before calculating a path, you can configure the following settings:
Path Analysis Set
The path analysis set contains a series of allocated object groups and path analysis profiles to calculate different types of path, such as layer 2 and layer 3 paths.
The following three built-in path analysis sets are supported for path calculation in the system.
Path Analysis Set |
Description |
|---|---|
L3 Path |
Calculate the Layer 3 path by using the information of layers upper than layer 3 in the OSI model. |
L3 Active Path |
Calculate the Layer 3 path by using live data. Note: With this option selected, the system will calculate the exact path between Cisco IOS devices (including Cisco IOS Routers, Cisco IOS Switch, and Cisco IOS XR) by inquiring the CEF table instead of load-balancing. It uses commands with configured parameters instead of retrieving the complete route table, MPLS VPNv4 Label table, and MPLS LFIB table (except for Cisco IOS XR). |
L2 Path |
Calculate the Layer 2 path by using the information of layers upper than Layer 2 in the OSI model. |
Protocol
The following protocols are supported for path calculation in the system.
Protocol |
Description |
|---|---|
IPv4 (default option) |
Calculate a path for IPv4. |
TCP |
Calculate a path for TCP. |
UDP |
Calculate a path for UDP. |

Data Source
The following data sources are supported for path calculation in the system.
Data Source |
Description |
|---|---|
Use the latest device data saved in the database directly. |
|
Live Network |
Log into the device instantly to retrieve live data. ▪Use Configuration in Current Baseline (selected by default) — use the configuration files that have been saved in Current Baseline, not real-time configuration data. |
Use the saved device data which is nearest to the specified historical time point. Search scope: ± 2 hours. |
