Configuring Burst Size in vFlow

The vflow-create and vflow-modify commands support a configurable burst-size parameter (i.e., the token bucket size). 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 value between 256 bytes and 134 MB (128 MiB). 

For example, to create a vFlow with a maximum bandwidth of 5 Gbps and a burst size of 12 MB, you can use the following command:

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