Logical Interfaces Overview

Logical Interfaces Overview

This topic describes logical interfaces supported by CX11x&CX31x&CX91x Series.

Table 4-7 Logical interfaces
Interface DescriptionConfiguration Reference Configuration Reference
Eth-Trunk interface An Eth-Trunk is formed by binding multiple Ethernet interfaces to provide more bandwidth and higher transmission reliability. For details about how to configure an Eth-Trunk interface, see Link Aggregation Configuration in the CX11x&CX31x&CX710&CX91x Series Switch Modules Configuration Guide: LAN .
VLANIF interface A VLANIF interface has Layer 3 features and enables VLANs to communicate after being assigned an IP address. For details about how to configure a VLANIF interface, see VLAN Configuration in the CX11x&CX31x&CX710&CX91x Series Switch Modules Configuration Guide: LAN Configuration.
Stack interface A stack interface is a logical interface used to implement the stacking function. The stacking function virtualizes multiple switches into a logical switch to provide massive data forwarding and improve network reliability in data centers. For details about how to configure a stack interface, see Stack Configuration in the CX11x&CX31x&CX710&CX91x Series Switch Modules Configuration Guide: Device Management Configuration
Loopback interface A loopback interface is always Up and can be configured with a 32-bit subnet mask. -
NULL interface A NULL interfaceused in route filtering because any network packets sent to this interface are discarded. -
Tunnel interface A tunnel interface has Layer 3 features, transmits packets, and identifies and processes packets transmitted over a tunnel.

For details about how to configure a tunnel interface, see IPv6 Transition Technology Configuration in the CX11x&CX31x&CX710&CX91x Series Switch Modules Configuration Guide: IP Service Configuration and GRE Configuration Guide in the CX11x&CX31x&CX710&CX91x Series Switch Modules Configuration Guide: VPN Configuration.
