Usage Information Related Commands If you configure interface type as CR4 with auto-negotiation enabled, also configure CR4 with auto-negotiation. Many DAC cable link issues are resolved by setting the interface type as CR4. interface - configures a physical interface. interface port-channel - configures a port channel group. keepalive Send keepalive packets periodically to keep an interface alive when it is not transmitting data. Syntax keepalive [seconds] To stop sending keepalive packets, use the no keepalive command. Parameters seconds (OPTIONAL) For interfaces with PPP encapsulation enabled, enter the number of seconds between keepalive packets. The range is from 0 to 23767. The default is 10 seconds. Defaults Command Modes Command History Enabled. INTERFACE Version 9.4(0.0) Supported on the FN I/O aggregator. This command is supported in Programmable-Mux (PMUX) mode only. Usage Information When you configure keepalive, the system sends a self-addressed packet out of the configured interface to verify that the far end of a WAN link is up. When you configure no keepalive, the system does not send keepalive packets and so the local end of a WAN link remains up even if the remote end is down. mtu Set the link maximum transmission unit (MTU) (frame size) for an Ethernet interface. Syntax mtu value To return to the default MTU value, use the no mtu command. Parameters value Enter a maximum frame size in bytes. The range is from 594 to 9252. MXL Switch Range is from 594 to 12000. The default is 1554. Defaults Command Modes 1554 INTERFACE 352
