Ethernet Interface Overview

Ethernet Interface Overview

Ethernet interfaces are used on LANs.

Physical interfaces on the device are Layer 2 Ethernet interfaces working at the data link layer. You cannot configure IP addresses for these interfaces. These interfaces can forward the received packets at Layer 2 or be added to a VLAN to forward packets at Layer 3 through corresponding VLANIF interfaces. Layer 2 Ethernet interfaces on the device include Ethernet electrical interfaces and optical interfaces.

Table 6-6 lists the attributes of Ethernet interfaces.
