To enable PPPoE (Point-to-Point Protocol over Ethernet) on a Remote Site profile, configure the Network Service using the command:

6-4CHAPTER 6: MANUAL SETUP

When the Network Service is set to RFC 1483, the profile’s IP WAN addresses can be dynamically learned with the DHCP protocol. To enable DHCP on a Remote Site profile:

1Set the network service to RFC 1483:

set vc <vc name> dynamic_ip_addressing dhcp_client

2Enable MAC encapsulated routing (MER): set vc <vc name> mac_routing enable

3Set dynamic IP addressing to DHCP:

set vc <vc name> dynamic_ip_addr dhcp_client

Enabling a Point-to-Point Protocol

PPP is enabled by default.

set vc <vc name> network_service pppoe

To enable PPPoA (Point-to-Point Protocol over ATM) on a Remote Site profile, configure the Network Service using the command:

set vc <vc name> network_service pppoa

Configuring ATM	The ATM parameters are supplied by your service provider. These parameters
Information	consist￿		of:
	￿	ATM VC information
	￿	ATM Category of Service parameters

ATM allows for permanent connections (PVCs) and switched connections (SVCs).

For a PVC, the required VC information parameters consist of the Virtual Path

Identifier (VPI) and Virtual Channel Identifier (VCI).

The VPI/VCI uniquely specify the path to the remote site and are placed in the ATM cell header that is used to route each cell to the remote site.

Two VC profiles with the same VPI and VCI cannot be enabled simultaneously. You may encounter this situation if you want to login to the same remote site with different PPP authentication parameters. You should delete all profiles using the same VPI/VCI and then enable the one that should be active.

Currently, the SVC capability is disabled in the OCR 812.

ATM Category of Service parameters specify characteristics (sometimes called traffic shaping parameters) for data transmitted from the OCR 812 to the remote site. They have no effect on data transmitted from the remote site to the

OCR 812.

The ATM VC information and Category of Service parameters are entered into the profile using the set vc <vc name> atm command.

For PVCs, you must enter VPI and VCI information for each profile:
