Ethernet Interface Configuration

Overview of Ethernet Interfaces

Ethernet interfaces include conventional Ethernet interfaces, Fast Ethernet (FE) interfaces, and Gigabit Ethernet (GE) interfaces.

Configuration Precautions for Ethernet Interface

Configuring an Ethernet Interface on an Interface Board

You can configure parameters for Ethernet interfaces on interface boards to ensure that physical connections work properly between devices.

Configuring Ethernet Sub-interfaces to Support Communication Between VLANs

To implement communication between hosts in a VLAN and hosts in another VLAN, create sub-interfaces on the Ethernet interface of a Layer 3 device that connects to a Layer 2 device and encapsulate 802.1q on the sub-interfaces.

Configuration Examples for Ethernet Interfaces or Sub-interfaces

This section provides configuration examples of Ethernet interfaces or sub-interfaces, including networking requirements, configuration roadmap, data preparation, and configuration files.
