Configuring the IFG

Configuring the IFG


An interframe gap (IFG) is used to separate two data packets, as shown in Figure 2-5. You can configure the IFG to change the packet forwarding rate on an interface, thereby adjusting the data forwarding capacity of the interface.

The packet forwarding rate, also called throughput, refers to the data forwarding capability on an interface and is measured in packet per second (pps). The packet forwarding rate is calculated based on the number of 64-byte data packets transmitted in a period. The lengths of preamble and IFG affect the packet forwarding rate.

The default IFG is the maximum value of 12 bytes and is recommended. If you set the IFG to a small value, the device will not have enough time to receive the next frame after receiving one data frame. The packets then cannot be processed in real time, which results in packet loss.

Figure 2-5  IFG


On the S12700, only the ET1D2L02QSC0 and ET1D2L08QSC0 interface cards support the IFG configuration.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run ifg ifg-value

    The IFG is configured.

    The default IFG is 12 bytes.
