  • Page 8: Bulk Configuring Interfaces

    Bulk configuring interfaces You can enter interface range view to bulk configure multiple interfaces with the same feature instead of configuring them one by one. For example, you can execute the shutdown command in interface range view to shut down a range of interfaces. Configuration restrictions and guidelines When you bulk configure interfaces in interface range view, follow these restrictions and guidelines: •...

  • Page 10: Configuring Ethernet Interfaces

    Configuring Ethernet interfaces Your device supports the following types of Ethernet interfaces: • Layer 2 Ethernet interfaces—Physical Ethernet interfaces operating at the data link layer (Layer 2) to switch packets. • Layer 3 Ethernet interfaces—Physical Ethernet interfaces operating at the network layer (Layer 3) to route packets.

Combining four 10-GE breakout interfaces into a 40-GE interface If you need higher bandwidth on a single interface, you can combine the four 10-GE breakout interfaces into a 40-GE interface.

  • Page 12: Configuring Basic Settings Of An Ethernet Interface

    Configuring basic settings of an Ethernet interface You can configure an Ethernet interface to operate in one of the following duplex modes: • Full-duplex mode—The interface can send and receive packets simultaneously. • Half-duplex mode—The interface can only send or receive packets at a given time. •...

  • Page 13: Configuring The Link Mode Of An Ethernet Interface

    Configuring the link mode of an Ethernet interface CAUTION: After you change the link mode of an Ethernet interface, all commands (except the shutdown command) on the Ethernet interface are restored to their defaults in the new link mode. An Ethernet interface can operate in either of the following modes: •...

  • Page 14: Configuring Physical State Change Suppression On An Ethernet Interface

    Configuring physical state change suppression on an Ethernet interface IMPORTANT: Do not enable this feature on an interface with RRPP, MSTP, or Smart Link enabled. The physical link state of an Ethernet interface is either up or down. Each time the physical link of an interface comes up or goes down, the interface immediately reports the change to the CPU.

  • Page 15: Configuring Generic Flow Control On An Ethernet Interface

    IMPORTANT: This feature is used only for debugging and troubleshooting. Perform this task to determine whether an Ethernet link operates correctly. Loopback testing includes the following types: • Internal loopback testing—Tests the device where the Ethernet interface resides. The Ethernet interface sends outgoing packets back to the local device. If the device fails to receive the packets, the device fails.

  • Page 16: Configuring Pfc On An Ethernet Interface

    When congestion occurs, the interface sends a flow control frame to its peer. When the interface receives a flow control frame from its peer, it suspends sending packets to its peer. • Rx-mode generic flow control—Enabled by using the flow-control receive enable command.
  • Page 17 Local (right) enable auto Default Peer (below) • Enabled if negotiation succeeds. Enabled Disabled auto • Disabled if negotiation fails. Disabled Disabled. Disabled Default Configuration restrictions and guidelines When you configure PFC, follow these restrictions and guidelines: • For IRF and other protocols to operate correctly, do not enable PFC for 802.1p priorities 0, 6, and 7.

  • Page 18: Enabling Eee On An Ethernet Interface

    NOTE: • Use the qos map-table command to map an 802.1p priority to a local priority. For more information about the qos map-table command, see ACL and QoS Command Reference. • After you enable PFC for an 802.1p priority, make sure the 802.1p priority uses the default 802.1p-local priority map.

  • Page 19: Forcibly Bringing Up A Fiber Port

    Forcibly bringing up a fiber port CAUTION: The following operations on a fiber port will cause link-down and link-up events before the port finally stays up: • Configure both the port up-mode command and the speed or duplex command. • Install or remove fibers or transceiver modules after you forcibly bring up the fiber port. As shown in Figure 1, a fiber port uses separate fibers for transmitting and receiving packets.

    • Typically, set the MDIX mode of the interface to AutoMDIX. Set the MDIX mode of the interface to MDI or MDIX only when the device cannot determine the cable type. • When a straight-through cable is used, configure the interface to operate in an MDIX mode different than its peer.

    Configuring loopback, null, and inloopback interfaces This chapter describes how to configure a loopback interface, a null interface, and an inloopback interface. Configuring a loopback interface A loopback interface is a virtual interface. The physical layer state of a loopback interface is always up unless the loopback interface is manually shut down.
