About Ingress Port Rate Limiting

A port rate limiting feature helps control the bandwidth for individual Fibre Channel ports. Port rate limiting is also referred to as ingress rate limiting because it controls ingress traffic into a Fibre Channel port. The feature controls traffic flow by limiting the number of frames that are transmitted out of the exit point on the MAC. Port rate limiting works on all Fibre Channel ports. The rate limit ranges from 1 to 100% and the default is 100%.

To configure the port rate limiting value using Fabric Manager, follow these steps:

  1. Expand Switches, expand FC Services and then select QoS in the Physical Attributes pane.
  2. Click the Rate Limit tab.
  3. Select the switch whose port rate limit you want to change.
  4. Enter the desired port rate limit in the Percent column.
  5. Click Apply Changes.
