Describes how to view and interpret the bidirectional flow path table with hop-by-hop metrics, including flow state, direction, packet loss, jitter, latency, and traffic statistics for releases before a specified version.
This section applies to releases before Cisco vManage Release 20.6.1 .
In the Flow Path and Metrics section, view bidirectional flow path table with hop-by-hop metrics. You can expand any trace instance in the log to view the following details:
|
Column |
Description |
|---|---|
| Last Update Time |
The flow path instances in running state are refreshed every 10 seconds and the time of the update is displayed. |
| Flow ID |
Flow IDs differentiate two identical flow path instances occurring at different times. |
| State |
This state helps you visualize potential issues with the flow. Only SLA state of the flow is supported. |
| Direction |
Directions could be upstream or downstream. The direction in which the first packet flow is identified is considered as upstream. |
| Local Color, Remote Color |
Local edge (source) and the remote edge (destination) colors indicate different WAN interfaces. |
| Local Drop(%) |
Packet drop on hop's local edge routers. |
| Remote Drop(%) |
Packet drop on hop's remote edge routers (WAN underlay drop on remote edge router excluded) |
| WAN Drop(%) |
Packet loss on WAN from hop's local edge router to remote edge router (includes WAN underlay drop on remote edge router, eg.IPSec Anti-Replay drop.) |
| Jitter(ms), Latency(ms) |
Jitter and latency metrics of the flow. These metrics help with evaluating the application performance in real time. |
| Total Packets, Total Bytes |
For each direction of the flow, total number of packets and total byte count are displayed. |
