Chapter 21 Configuring ATM Connections
ATM Connection Requirements
You can add ATM connections by using either the Cisco WAN Manager Connection Manager or a
node’s command line interface (CLI). Typically, the Cisco WAN Manager Connection Manager is the
preferred method because it has an easy to use GUI interface. The CLI may be the method of choice in
some special cases or during initial node setup for local nodes.
Overview of Procedure to add ATM Connections
In general, to add ATM connections:
Step 1
Configure the access port and access service lines connecting to the customer premise equipment.
Step 2 Configure the trunks across the network appropriately for the type of connection.
Step 3 Use the addcon command to add a connection, first specifying the service type and then the appropriate
parameters for the connection.
For example, when configuring a BXM for CPE connections:
Step 1 Configure the BXM for port mode,
Step 2
Up a line by using the upln command
Step 3 Configure the line by using the cnfln command.
Step 4 Configure the associated port by using the cnfport command
Step 5
Up the associated port by using the upport command.
Step 6 Then add the ATM connections by using the addcon command.
Connection Routing
ATM connections for a BXM card are identified by these numbers:
•
slot number (in the BPX switch shelf where the BXM is located)
• port number (one of the ATM ports on the BXM)
• Virtual Path Identifier (VPI)
•
Virtual Circuit Identifier (VCI) – (* for virtual path connections)
The slot and port are related to the BPX switch hardware.
Virtual path connections (VPCs) are identified by a “*” for the VCI field.
Virtual circuit connections (VCCs) are identified by both a VPI and VCI field.
Connections added to the network are automatically routed once the end points are specified. This
AutoRoute feature is standard with all BPX and IGX switches. The network automatically detects trunk
failures and routes connections around the failures.
