Chapter3 Configuring with the Command-Line Interface
Configuring 1-Port ADSL WAN Interface Card
Prerequisites
A 1-Port ADSL WIC must be installed in the router to match the DSL service to be configured.
Configuration Tasks
See the following sections for configuration tasks for this feature. Each task in the list is identified as
either required or optional:
• Configuring the ADSL Port on the ADSL WAN Interface Card (required)
• Verifying ATM Configuration (optional)
Features used on the ADSL WAN interface card must also be configured on the DSLAM. See the
documentation for the specific DSLAM for information about configuring features.
Configuring the ADSL Port on the ADSL WAN Interface Card
To configure an ADSL port on the ADSL WAN interface card, complete the following steps:
Command Purpose
Step1
Router> configure terminal
Enter global configuration mode.
Step2
Router(config)# interface
atm slot/port
Enter ATM configuration mode for the ATM interface in
the specified slot and port.
Step3
Router(config-if)# ip
address IP-address
Assign an IP address to the ADSL ATM interface.
Step4
Router(config-if)# pvc
[name] vpi/vci
Entes atm-virtual-circuit (interface-atm-vc) configuration
mode, and configures a new ATM PVC by assigning a
name (optional) and virtual path identifier (VPI)/virtual
channel identifier (VCI) numbers.
The default traffic shaping is UBR; the default
encapsulation is AAL5+LLC/SNAP.
Step5
Router(config-if-vc)#
protocol ip IP-address
(Optional) Enable IP connectivity and create a
point-to-point IP address for the virtual circuit (VC).
Step6
Router(config-if-vc)# vbr-rt
peak-rate average-rate burst
(Optional) Configure the PVC for real-time variable bit
rate (VBR) traffic shaping.
• peak rate—Peak information rate (PIR)
• average rate—Average information rate (AIR)
• burst—Burst size in cells
Step7
Router(config-if-vc)#
encapsulation {aal2 |
aal5ciscoppp | aal5mux |
aal5nlpid | aal5snap}
(Optional) Configure the ATM adaptation layer (AAL) and
encapsulation type.
• aal2—AAL2
• aal5ciscoppp—Cisco PPP over AAL5
• aal5mux—AAL5+MUX
• aal5nlpid—AAL5+NLPID
• aal5snap—AAL5+LLC/SNAP (the default)
