VPI/VCI Detect Setting Specify the port behavior with regard to VPI/VCI
detection:
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.
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 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
protocol codes 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.
