Specifying the flow control type for a network interface

You can specify the flow control type for a network interface to manage the flow of frames between two directly connected link-partners. By controlling the transmission rate of data packets between the link-partners, you can effectively manage the network traffic.

Before you begin

About this task

The configured flow control setting is advertised during autonegotiation. If autonegotiation succeeds, the operational flow control setting is determined based on the negotiated speed and the value advertised by the other device. If autonegotiation fails, the configured flow control setting is used.
Note: Only 1-Gb interfaces support autonegotiation. For 10-Gb interfaces, the network interface on the storage system and the link-partner (usually a switch) should be configured with compatible settings.

Step

  1. To specify the flow control type, enter the following command: ifconfig interface_name flowcontrol value
    interface_name is the name of the network interface.
    value is the flow control type. You can specify the following values for the flowcontrol option:
    none
    No flow control
    receive
    Able to receive flow control frames
    send
    Able to send flow control frames
    full
    Able to send and receive flow control frames

    The default flow control type is full.

    Example
    To turn off flow control on the e0a interface, enter the following command: ifconfig e0a flowcontrol none
