Traffic Shaping and Rate Limiting

Traffic shaping controls the amount and volume of traffic transmitted through a network. This has the effect of smoothing temporary traffic bursts over time.

Rate limiting specifies the maximum ingress bandwidth allowed, typically used to rate limit the inbound transmission rate. This value is controlled independently of any per-flow input policing configurations. It is effectively a hard-limit for allowed ingress traffic rate.

traffic-shape

Use this command to enable traffic shaping by specifying the maximum transmission bandwidth limit for all interfaces (Global Config) or for a single interface (Interface Config).
