Configuring a Logical Interface
- Configuring a Sub-interface
A sub-interface is a virtual interface configured on a physical interface to allow users who belong to different VLANs to communicate with each other. - Configuring a Loopback Interface
A loopback interface is always Up at the physical layer and link layer unless it is manually shut down. You can configure loopback interfaces to enhance network reliability. - Configuring a NULL Interface
A NULL interface is always Up once created automatically by the system. It does not forward packet but can be used to filter packet. - Configuring an MP Group Interface
A Multilink PPP (MP) group interface is used to perform MP binding to increase link bandwidth. - Configuring a Dialer Interface
By binding a physical interface (such as a serial, BRI, PRI, or asynchronous interface) to a dialer interface, you can enable the physical interface to inherit the configuration of the dialer interface. - Configuring a VE Interface
Virtual-Ethernet (VE) interfaces allow one data link protocol to transmit data of other link layer protocols. - Configuring a Virtual-Template Interface
When a PPP link needs to transmit data of other link layer protocols, configure a Virtual-Template (VT) interface. - Configuring a Virtual Interface
