3 Configuring the Switch

Rate Limit Granularity

Rate limit granularity is an additional feature enabling the network manager greater control over traffic on the network. The “rate limit granularity” is multiplied by the “rate limit level” (page 3-84) to set the actual rate limit for an interface. Granularity is a global setting that applies to Fast Ethernet or Gigabit Ethernet interfaces.

Command Usage

For Fast Ethernet interfaces, the rate limit granularity can be set to 512 Kbps, 1 Mbps, or 3.3 Mbps

For Gigabit Ethernet interfaces, the rate limit granularity is 33.3 Mbps.

Web – Click Port, Rate Limit, Granularity. Select the required rate limit granularity for Fast Ethernet and Gigabit Ethernet, and click apply.
