Usage Guidelines

You can configure the store-and- forward command in global configuration mode to enable the store-and-forward method for packet-forwarding.

By default, when flow control is enabled globally and auto-negotiation is on, flow control is enabled and advertised on 10/100/1000M ports. If auto-negotiation is off or if the port speed was configured manually, flow control is neither negotiated with nor advertised to the peer.

Note: Enabling only port auto-negotiation does not enable flow control negotiation. You must use the flow-controlneg-on command to enable flow-control negotiation.

The no form of the command disables flow control.

Examples

The following example disables flow control globally.

device(config)# no flow-control

The following example enables flow control on ethernet ports 1/1/11 to 1/1/15.

device(config)# interface ethernet 1/1/11 to 1/1/15
device(config-mif-1/1/11-1/1/15)# flow-control

The following example disables flow control on ethernet port 1/1/9.

device(config)# interface ethernet 1/1/9
device(config-if-e1000-1/1/9)# no flow-control
