Configuring Burst Size in vFlow for Maximum Bandwidth

The vflow-create and vflow-modify commands support a configurable burst-size parameter. This feature enables you to specify different burst-sizes for different types of metered traffic. For example, you can configure higher burst levels for a metered application that may produce bursty traffic patterns when you click on it, such as a media-rich Web page link.

This feature defaults to burst-size auto, which auto-calculates the burst size based on the maximum bandwidth settings for the vFlow. You can configure a burst-size number between 0 through 134MB.

The command syntax is:

CLI (network-admin@switch) > vflow-create name name-string scope local|fabric in-port port-list bw-max bw-max-number burst-size number

For example, to create a vFlow with a burst size of 12 MB, use the following syntax:

CLI (network-admin@switch) > vflow-create name flow1 scope local in-port 12 bw-max 5G burst-size 12M
