flow-control

	CAUTION: Configuring generic flow control on an Ethernet interface will cause link-up and link-down events before the interface finally stays up.

Use flow-control to enable TxRx mode generic flow control on an Ethernet interface.

Use undo flow-control to disable generic flow control on the Ethernet interface.

Usage guidelines

To implement flow control on a link, enable the generic flow control function at both ends of the link.

TxRx mode generic flow control enables an Ethernet interface to perform the following actions:

• Receive common pause frames from its peer.

• Send common pause frames to notify its peer of congestions.

With the flow-control command configured, an interface can both send and receive flow control frames:

• When congested, the interface sends a flow control frame to its peer.

• Upon receiving a flow control frame from the peer, the interface suspends sending packets.

Examples

# Enable TxRx mode generic flow control on Ten-GigabitEthernet 1/0/1.
