Zhone Technologies 4929 DSLAM manual Accepted from source IP addresses in the ranges

Configuration Using the NMS

Parameter	Description
Port Mode Setting	Specify a port mode:
	z Fixed – The upstream and downstream rates
	are fixed.
	z Adaptive – The ports will automatically train
	up to the best possible speed supported by the
	DSLAM, the modem at the remote end, and
	the copper cable pair connecting the two.
	z Fixed Adaptive – The ports will automatically
	train up to the best possible speed, subject to a
	user-specified maximum upstream and
	downstream bandwidth.
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.
Data Rate Setting	If you have selected a Port Mode of Fixed or
	Fixed Adaptive, specify the maximum upstream
	and downstream rates, in bps.
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.
VPI and VCI	Specify a default VPI and VCI if VPI/VCI
	Detect Setting (above) is Off.
