Monitor TCP Optimization

If TCP optimization is enabled on a vEdge router, you can view information about how the optimization is affecting the processing and throughput of TCP data traffic on the router:

  1. In vManage NMS, select the Monitor ► Network screen.
  2. Locate the vEdge router using the Sort options drop-down and the Search box. Or scroll through the list of devices in the device table.
  3. Select the vEdge router by clicking its hostname. The screen changes and the left pane lists the categories of information you can display about the device.
  4. Click TCP Optimization–WAN Throughput in the left pane. The right pane displays the WAN throughput, in megabits per second (Mbps).

The upper part of the right pane contains the following elements:

  • Chart Options bar—Located directly under the device name, this bar includes the Chart Options drop-down and time periods. Click Chart Options to select the type of data to display. Click a predefined or custom time period for which to display data.
  • Average optimized throughput information, in graphical format.
  • WAN graph legend—Identifies non-optimized and TCP-optimized packet throughput.

The lower part of the right pane shows the hourly average throughput and the total optimized throughput, both in megabits per second.

View TCP Flows

Click TCP Optimization–Flows in the left pane to display information about TCP-optimized traffic flows. The upper part of the right pane contains the following elements:

  • Chart Options bar—Located directly under the device name, this bar includes the Chart Options drop-down and time periods. Click Chart Options to select the type of data to display. Click a predefined or custom time period for which to display data.
  • Average optimized throughput information in graphical format.
  • Flows graph legend—Identifies non-optimized and TCP optimized packet throughput.

The lower part of the right pane contains the following elements:

  • Set perspective—Select the flow direction.
  • Filter criteria.
  • Flow table that lists the flow destination, usage, and percentage of total traffic for all TCP-optimized flows. By default, the first six flows are selected. Click the checkbox to the left to select and deselect flows to display. The graphical display in the upper part of the right pane plots information for the selected flows.

View TCP Top Talkers

Click TCP Optimization–Top Talkers in the left pane to display information about the tunnels over which the most TCP-optimized traffic is flowing. The upper part of the right pane contains the following elements:

  • Chart Options bar—Located directly under the device name, this bar includes the Chart Options drop-down and time periods. Click Chart Options to select the type of data to display. Click a predefined or custom time period for which to display data.
  • TCP-optimized traffic volume per tunnel, in bar graph format.

The lower part of the right pane contains the following elements:

  • Filter criteria.
  • Flow table that lists information about each of the tunnels.

Revision History
