Configuring a Subinterface for each PVC
You must configure an ATM subinterface to define the endpoint of the ADSL
connection. By default, each ATM interface supports up to 16 permanent
virtual circuits (PVCs), so you can create a maximum of 16 subinterfaces on
each ATM interface.
Configuring a subinterface involves the following basic steps:
1. Create the ATM subinterface.
2. Activate the ATM subinterface.
3. Assign the subinterface a virtual path identifier (VPI) and virtual channel
identifier (VCI).
4. Set the encapsulation type.
5. Assign an IP address to the ATM subinterface.
If you are configuring PPPoE or PPPoA for the ADSL connection, you will
need to complete some additional steps. You will also need to assign the IP
address to the PPP interface, rather than to the ATM subinterface.
These are the basic steps for configuring the ATM subinterface, but you can
configure other settings (such as quality of service, access controls, and
backup settings) for the subinterface as well.
Creating the Subinterface
From the global configuration mode context or the ATM interface configura-
tion mode context, enter:
Syntax: interface <interface> <number.subinterface number>
Replace <interface> with atm, and replace <number> with the number of
the ATM interface you created previously. Then replace <subinterface> with
a number between 1 and 65535.
For example, if you want to configure the ATM 1.1 subinterface, enter:
ProCurve(config-atm 1)# interface atm 1.1
