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:
1 Set the network service to RFC 1483:
set vc <vc name> dynamic_ip_addressing dhcp_client
2 Enable MAC encapsulated routing (MER):
set vc <vc name> mac_routing enable
3 Set 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.
To enable PPPoE (Point-to-Point Protocol over Ethernet) on a Remote Site


profile, configure the Network Service using the command:
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
The ATM parameters are supplied by your service provider. These parameters
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:
