Configuring Flow Control on an Ethernet Interface
When flow control is enabled on both sides, if traffic congestion occurs at the ingress interface, it will
send a Pause frame notifying the egress interface to temporarily suspend the sending of packets. The
egress interface is expected to stop sending any new packet when it receives the Pause frame. In this
way, flow control helps to avoid dropping of packets. Note that this will be possible only after flow control
is enabled on both the ingress and egress interfaces.
Follow these steps to enable flow control on an Ethernet interface:
