VPI/VCI Detect Setting

Specify the port behavior with regard to VPI/

VCI detection:

z

On – The DSLAM will monitor the line to 

determine the VPI and VCI settings of the 

remote ADSL modem and set itself 

accordingly. If no ATM cells are detected (at 

any VPI/VCI setting), the port will default to 

VPI 0 and VCI 35.

z

Off – The port will use the default setting of 

VPI and VCI (0/35 if not changed by the 

setting of VPI and VCI, below), or lock in the 

VPI/VCI already discovered while VPI/VCI 

detection was On. 

Filter IP Address Settings Specify up to four IP address ranges. Packets are 

accepted from source IP addresses in the ranges 

specified. 

Protocol Setting

Click in the check box to enable Protocol Setting 

detection. Select Allow Selected and specify up 

to four Ethertypes allowed on the ports.

DHCP Option 82

Specify whether DHCP Option 82 is enabled, 

and if it is, whether packets are identified by IP 

address or circuit ID. This identifier is added to 

packets to let your DHCP Server recognize 

which DSLAM port an IP address request is 

coming from, thereby allowing the DHCP 

Server to limit the number of IP addresses 

assigned per port.

Layer 2 Port Filter 

Settings

Click in the check box if you want to filter by 

MAC address the packets on this port.

MAC 1 – MAC 3

Enter up to three MAC addresses.

Unlimited # of MACs or 

Define # of MACs

Specify whether the number of MAC addresses 

with access to the port is to be limited to a 

certain number (not including MAC 1, MAC 2, 

and MAC 3, if specified above).

VPI and VCI

Specify a default VPI and VCI if VPI/VCI 

Detect Setting (above) is Off.

Frame Type

Specify whether the ports use Logical Link 

Control (LLC) or Virtual Channel Multiplexing 

(VCM) bridged encapsulation. These are defined 

in RFC 1483.

Standard Mode

Specify the ports’ DSL mode.
