RuggedCom RX1000, RX1100 manual PPPoE On Native Ethernet Interfaces Fundamentals

RuggedRouter™ User Guide

The last 2-bytes of the VLAN tag contain the following information: the first 3-bits are a User Priority Field that may be used to assign a priority level to the Ethernet frame. The next 1-bit is a Canonical Format Indicator (CFI) used in Ethernet frames to indicate the presence of a Routing Information Field (RIF). The last 12-bits are the VLAN Identifier (VID) which uniquely identifies the VLAN to which the Ethernet frame belongs.

PPPoE On Native Ethernet Interfaces Fundamentals

The RuggedRouter supports PPPoE (Point-to-Point Protocol Over Ethernet) over both external modems (described here) and internal interfaces (described in the chapter “PPPOE On ADSL”). The PPPOE On ADSL chapter contains more useful information on PPPOE Authentication, Addresses, DNS Servers and MTU Issues.

Only one PPPoE interface can be created on each Ethernet Interface. Each PPPoE interface name is assigned internally. The name is “pppX”, where X is 10 plus the native Ethernet interface the PPPoE is created upon (e.g. a PPPoE on eth1 is ppp11).
