interface Use this command to configure parameters for Ethernet and port-channel interfaces. While in Global Configuration mode, enter the interface command with a specific interface. To exit to Global Configuration mode, enter exit. To return to Privileged Exec mode, press Ctrl-Z or enter end. Additional forms of the interface command enable configuring VLANs, tunnels, the loopback interface, the out-of-band interface, and ranges of interfaces. See interface vlan, interface tunnel, interface loopback, and interface range. Syntax interface {gigabitethernet unit/slot/port | port-channel port-channel-number | tengigabitethernet unit/slot/port | twentyfivegigabitethernet unit/slot/port | fortygigabitethernet unit/slot/port} Default Configuration This command has no default configuration. Command Mode Global Configuration, Interface Configuration User Guidelines Dell EMC Networking switches implement receive flow control only. They never issue a flow control PAUSE frame when congested, but will respect received flow control PAUSE frames received from other switches. Disabling flow control 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 autonegotiation 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 as the PHY is reset. Enabling flow control on some ports and not others can lead to excessive packet loss in situations where some ports on the switch have been paused and the internal packet buffers are consumed. This situation may cause traffic Layer 2 Switching Commands 415
