Configuring an edge-to-edge flow through an egress port using virtual port IDs

Figure 508

, provides the values for and a diagram of the following example procedure which

monitors a flow from Device B to Device A egressing through EX_Port1, the source device is Device
B′, the destination device is Device A, and the egress port is EX_Port1 (traffic is running from right
to left).

The following example creates a flow (e2e_src_dcx) that filters out frames passing from one edge
fabric (01f001) to another edge fabric (220200) using a specific egress port (219) on the
backbone.

1. Right-click the port (219) on which you want to monitor the flow and select Fabric Vision > Flow

> Add.

The Add Flow Definition dialog box displays with the following default criteria and flow
identifiers pre-populated:

Feature — Monitor

Direction — Bidirectional

Source Device — Source identifier

Destination Device — * (an asterisk allows you to use any port)

Egress port — port number (219)

2. Enter a name (e2e_src_dcx) for the flow definition in the Name field.

The name cannot be over 20 characters and can only include alphanumeric character,or
underscores.

NOTE

For a physical switch, the name must be unique. However, for logical switches, the name does
not have to be unique.

3. Select the Source to Destination option for Direction.

4. Select the Persist over switch reboots check box to persist this flow definition over reboots.

5. Select the Activate all selected features check box to immediately activate the flow after

creation.

6. Select the Port Address option for End Device.

7. Enter the source port address (01f001) in the Source field.

8. Enter the destination port address (220200) in the Destination field.

9. Select OK to save the definition.

When the flow definition activates, the Flow Vision dialog box displays with the new flow
selected (highlighted) in the Flow Definitions table. To review the sub-flow data for the selected
flow, refer to

“Monitoring a Flow Monitor flow”

on page 1149".
