3. DSL Card Configuration
8000-A2-GB26-70 April 2002
3-25
Card VNID Table (Continued) A-E-B
IP Scoping – Enable/blank (disable) (Default = Enable). If Mux Fwd is set to Disable, then
IP Scoping is set to Disable.
„
When IP Scoping is enabled, Dynamic Host Configuration Protocol (DHCP) scoping
is also enabled and the DSL card intercepts IP ARP and DHCP transaction
messages.
„
When IP Scoping is disabled, DHCP client entries are not added to the Client table
and non-IP traffic is forwarded. If IP Scoping is enabled, non-IP traffic is not
forwarded.
DHCP clients in one VNID domain can only obtain the IP addresses in one IP subnet, and
the core router’s primary IP address is part of that subnet. As a result, DHCP clients in
one VNID domain cannot be in different subnets. If the DHCP scope falls in a statically
configured subnet, all the dynamic clients will get an IP address in that static subnet. This
assumes that the core router is configured for DHCP relay.
Set this option to Disable if you are using a DSL Router.
VNID Auth – Enter a VNID number. When VNID Auth is enabled, the DSL port card
authenticates the traffic from the DSL Router.
Domain Name – Enter the domain name of the Internet Service Provider (ISP)
(30 characters maximum).
VNID Binding Table A-E-C
Gives the user with Administrator permission the ability to configure one VNID association
on an individual port/interface.
Item – Enter the Item number identifying the row listing the desired VNID (1–10)
(Default = 1). If VNID tagging has not been set (see
General (General Bridge Parameters)
A-E-A on page 3-24), then only the default VNID will display to allow configuration of its
NHR.
DSL Interface – Enter the DSL interface. Valid choices for the DSL card are dsl1:1
through dsl4:1 = 4-port DSL card interface; dsl1:1 through dsl12:1 = 12-port DSL card
interface, dsl1:1 through dsl24:1 = 24-port DSL card interface (Default = dsl1:1). Only one
interface per port is allowed.
Active VNIDs – Number of the VNID. Enter 2–4000 for DSL cards with an Ethernet
network interface, 2–255 for DSL cards with an ATM network interface (Default = none).
For a list of VNIDs, press Ctrl-v.
Default NHR – Enter the IP address of the Next Hop Router (NHR) in nnn.nnn.nnn.nnn
format (Default = none). Enter a space to delete the current NHR entry (make sure all
users on the same VNID/port have an NHR entry). If the NHR IP address does not exist
for that client in the client table, a default NHR IP address is used. If the default NHR IP
address does not exist, the Address Resolution Protocol (ARP) request is ignored. Valid
value is 0–255 for each octet. This is an optional field.
Domain Name – Displays the domain name, if one has been entered (read-only) in the
Card VNID screen (A-E-B).
