376 Ethernet Configuration CommandsUser GuidelinesDell Networking switches implement receive flow control only. They neverissue a flow control PAUSE frame when congested, but will respect receivedflow control PAUSE frames received from other switches. Disabling flowcontrol causes the switch to ignore received PAUSE frames.Interface specific configuration overrides any global configuration.Changing the flow control setting on a copper port will restart auto-negotiation and cause a brief link-flap while auto-negotiation occurs.Changing the flow control setting on a fiber port may cause a brief link flap asthe PHY is reset.Enabling flow control on some ports and not others can lead to excessivepacket loss in situations where some ports on the switch have been pausedand the internal packet buffers are consumed. This situation may cause trafficloss on other ports that are not congested or flow controlled.

Separate non-consecutiveports with a comma and no spaces; use a hyphen to designate a range ofports. For more detailed information, see Operating on Multiple Objects(Range). The command line buffer parses up to the maximum number ofcommand line characters possible in the port-range parameter.
