3. DSL Card Configuration

Configuring VNID(s) on a DSL Card
A VNID is a Virtual Network Identifier known as the 802.1Q tag between port cards
with an Ethernet network interface and the Interworking Packet Concentrator
(IPC). This directs traffic between the ISP and the end user. Tagging occurs
between the DSL card and the IPC to ensure that data is sent to the correct
location. This helps to ensure that data is not broadcast to all ports when Mux
forwarding is enabled. To enable VNID tagging for port cards with an Ethernet
network interface, you must first ensure that matching groups are configured on
the IPC.
VNID configuration is required on DSL port cards when the port card is
operating in the VNET-Bridged mode. However, when a DSL port card with an
ATM Network interface is operating in Standard mode, no VNID configuration
is required.
802.1Q VLANs must be configured on the IPC when a DSL port card with an
Ethernet Network interface is used. However, 802.1Q VLANs are not required
when a DSL port card with an ATM Network interface is used in conjunction
with an SCM card in the Hotwire 8820 GranDSLAM.
Before configuring VNIDs, you must enable VNID tagging (
A-E-A
), then reset the
card.
NOTE:
Before configuring VNIDs, determine what type of endpoints are attached.
Desired DSL port card configuration settings may differ, depending on the SN
attached.
