Viewing Traffic Flows

CloudVision lets you analyze the network traffic routed through a single device or through all devices that have flow tracking configured.
Note: Traffic flows return tunneled flows when the inner packet headers matches the user's query.
You can drill down into the details of global and device specific network flow activities using bar charts, stacked time series graphs, and tables of usage statistics. See Accessing the Global Traffic Flows Screen and Accessing the Device Specific Traffic Flows Screen.
Note: You can drill down the details of device specific network flow activities using heatmaps also.

To view the data on traffic flows, you must enable traffic flow tracking in devices to get data. See Enabling Traffic Flow Tracking.

Enabling Traffic Flow Tracking

Enabling flow tracking on a device allows CloudVision to provide a detailed breakdown of the forwarded network traffic. Traffic flow tracking is enabled through either of the following methods:

Enable sFlow Sampling on a Device

Arista switches provide a single sFlow agent instance that samples ingress traffic from all Ethernet and port channel interfaces.

Run the following commands to enable sFlow sampling on a device:

switch(config)#sflow sample <sampling rate>
switch(config)#sflow polling-interval <polling interval>
switch(config)#sflow destination 127.0.0.1
switch(config)#sflow source-interface <source interface>
switch(config)#sflow run

sFlow monitors a random sample of packets at the configured sampling rate. Reported bandwidth and packet measurements are scaled up using the sampling rate to provide estimates of actual bandwidth usage and packet counts.

Enable Hardware Based IPFIX Flow Tracking

Arista switches also allow exporting flow information using the IPFIX format.

Run the following commands to enable hardware based IPFIX flow tracking:

switch(config)#flow tracking hardware
switch(config)#!
switch(config)#tracker <tracker name>
switch(config)#record export on inactive timeout <inactive timeout>
switch(config)#record export on interval <interval>
switch(config)#record format ipfix standard timestamps counters
switch(config)#!
switch(config)#exporter <exporter name>
switch(config)#collector <loopback interface ip>
switch(config)#local interface <loopback interface>
switch(config)#template interval <interval>
switch(config)#no shutdown
switch(config)#exit
switch(config)#interface <interface>
switch(config)#flow tracker hardware <tracker name>
switch(config)#no shutdown

Accessing the Global Traffic Flows Screen

To view the global traffic flows screen, navigate to Devices > Traffic Flows on the CloudVision portal. This screen displays information about traffic flows captured by all devices on the network with flow monitoring enabled.See the figure below.

The heatmap plots two breakdowns against each other. For example, the user selects top 20 source hosts vs. top 20 destination hosts. The system displays the top 20 destination hosts that communicated with any of those top 20 source hosts.

Each pairing of source host and destination host is shown as a cell in the grid. Cells are displayed in various shades of green based on their usage. The higher the usage, the darker the green shade.

Note: The system displays an empty cell if there is no usage.

Status of Interfaces

The Interfaces section provides status of Ethernet interfaces, VLAN interfaces, IP interfaces, and port channels.

Figure 18. Interfaces Section

Sub-sections provide detailed information on Ethernet interfaces, routed ports, port channels, traffic counters, LLDP neighbors, and Power Over Ethernet.

Power Over Ethernet

Power Over Ethernet (PoE) is a technology for delivering electrical power along with network data over physical Ethernet connections. Some benefits of PoE are provided below:

  • Reduces the need of extension cables and additional outlets
  • Provides a reliable power source on difficult terrain
  • Prevents data transmission hiccups
  • Substantial reductions in space usage, cost, and time

In CloudVision, the Power Over Ethernet screen provides a summary of all interfaces along with information on each interface.

Figure 19. Power Over Ethernet Screen

The Power Over Ethernet screen displays the following information:

  • Summary of All Interfaces
    • Total Approved Power - Sum of the approved maximum power amounts configured for each Ethernet port
    • Total Granted Power - Sum of the approved power amounts minus power loss to transmission over Ethernet cables
    • Total Output Power - Sum of actual power amounts delivered to each powered Ethernet device
  • Information on Individual Interfaces
    • Interface - Interface name
    • Port Class - Maximum power in watts (W)
    • Port State - Operational status of a PoE device connected to the port
    • Approved Power - Configured maximum power output in watts (W) for the interface
    • Granted Power - Maximum power available to the device
    • Output Power - Power drawn by the device
    • Output Current - Current available on the PoE link in milliamps (mA)
    • Output Voltage - Voltage available over the PoE link in volts (V)
Note: PoE metrics are also available in the Metrics Explorer and can be built into custom metrics dashboards. Data on individual interfaces is available under the Interfaces metric type. Aggregate data totals of each device are available under the Devices metric type. See Accessing Metrics.
