Chapter 7: Second Level Commands

2.SG-1 as xDSL aggregator using Gigabit Ethernet network

In this scenario, a PPP session is initiated on an Ethernet-connected client through a standard ADSL modem. The session is transported over the Ethernet and terminated by the SG-1, which is acting as an xDSL aggregator.

Scenario highlights:

The SG-1 terminates the PPPoE sessions initiated at users PCs and grants a service.

User packets are passed as follows:

The user PC, which runs PPP client, encapsulates the PPP packet with Ethernet.

The PPPoE packet is being sent from the user PC to the xDSL modem.

The xDSL modem encapsulates it with DSL.

The DSLAM de-encapsulates the DSL header and send the Ethernet packets including broadcasts.

The SG-1 de-encapsulates the Ethernet and terminate the PPP session.

Using the pppoe enable command

Host(config)# pppoe enable interface

The pppoe enable interface command enables PPPoE negotiation for a specific interface in the system.

Usage

pppoe enable interface <slot number>\<port number\[sub-interface number]>

Parameter(s)

Table 7-10. pppoe enable parameters

 

Parameter

Description

Legal values/range

<slot

number>

Slot number.

0 - 2

<port

number>

Physical port number.

0 - 2

<sub-interface number>

Sub interface number.

1- 2000

Example(s)

Host(config)# pppoa enable interface 0 \ 1

Using the no pppoe enable command

Host(config)# no pppoe enable interface

The no pppoe enable interface command disables PPPoE negotiation for a specific interface in the system. Usage

no pppoe enable interface <slot number>\<port number\[sub-interface number]>

For parameters and examples, refer to “Using the pppoe enable command”.
