NOTE: The Inbound Rate Limiting function is not supported on ports connected to SmartTrunk segments.

When to Use

To limit the rate of traffic entering and leaving the SmartSwitch device on a per port/priority basis. Up to three inbound rules and three outbound rules can be programmed per port to control traffic according to the priority entries. The rules also contain the programmed traffic rate. The allowable range for the rate limit is 1 Kbps to 1 Gbps.

The outbound and inbound rate limit is configured for a given port and list of priorities. The list of priorities can include one, some, or all of the eight 802.1p priority levels. The combined rate of all traffic entering and exiting the port with the priorities configured to that port is not allowed to exceed the programmed limit. If the rate exceeds the programmed limit, frames are dropped until the rate falls below the limit.

For more information about the application of Rate Limiting and an example of how it can be used, refer to Section 8.8.3.

How to Access

Use the arrow keys to highlight the RATE LIMITING menu item on the 802.1p Configuration Menu screen and press ENTER. The Rate Limiting Configuration screen, Figure 8-10, displays.
