Overview of Logical Interfaces

Overview of Logical Interfaces

This section describes logical interfaces supported by switches.

  • Eth-Trunk

    An Eth-Trunk has Layer 2 features and is formed by binding multiple Ethernet interfaces to provide more bandwidth and higher transmission reliability. For details about how to configure an Eth-Trunk, see Link Aggregation Configuration in the S600-E V200R012C00 Configuration Guide - Ethernet Switching.

  • VLANIF interface

    A VLANIF interface has Layer 3 features, and enables VLANs to communicate and can have Layer 3 services deployed after being assigned an IP address. For details about how to configure a VLANIF interface, see Configuration Examples in "VLAN Configuration" in the S600-E V200R012C00 Configuration Guide - Ethernet Switching.

  • Loopback interface

    According to TCP/IP, an interface with an IP address in the range of to is a loopback interface. A loopback interface can be either of the following:

    • Loopback interface

      A loopback interface is used when you need an interface that must be always in the Up state. A loopback interface has the following advantages:

      • Once a loopback interface is created, its physical status and data link protocol status always stay Up, regardless of whether an IP address is configured for the loopback interface.

      • A loopback interface can be assigned an IP address with a 32-bit mask, which reduces address consumption. The IP address of a loopback interface can be advertised immediately after being configured.

      • No link layer protocol can be configured for a loopback interface. Therefore, no data link layer negotiation is required, allowing the link layer protocol status of the interface to stay Up.

      • The device drops the packet with a non-local IP address as the destination IP address and a local loopback interface as the outbound interface.

      The advantages of a loopback interface help improve configuration reliability. The IP address of a loopback interface can be used as follows:
      • Can be configured as a packet's source IP address to improve network reliability.
      • Can be used to control an access interface and filter logs to simplify information displaying.
    • InLoopback0 interface

      An InLoopBack0 interface is a fixed loopback interface that is automatically created at the system startup.

      An InLoopBack0 interface uses the fixed loopback address to receive data packets destined for the host where the InLoopBack0 interface resides. The loopback address of an InLoopBack0 interface is not advertised.

  • NULL interface

    A null interface is used to filter routes because any data packets received by the null interface are discarded.
