Overview Of Procedure To Add Atm Connections; Connection Routing - Cisco BPX 8620 Installation And Configuration Manual

Chapter 21 Configuring ATM Connections
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, use the following procedure:
Configure the access port and access service lines connecting to the customer premise equipment.
Step 1
Configure the trunks across the network appropriately for the type of connection.
Step 2
Use the addcon command to add a connection, first specifying the service type and then the appropriate
Step 3
parameters for the connection.
For example, when configuring a BXM for CPE connections, use the following procedure:
Configure the BXM for port mode,
Step 1
Up a line by using the upln command
Step 2
Configure the line by using the cnfln command.
Step 3
Step 4 Configure the associated port by using the cnfport command
Up the associated port by using the upport command.
Step 5
Add the ATM connections by using the addcon command.
Step 6

Connection Routing

ATM connections for a BXM card are identified by the following numbers:
•
•
•
•
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
Automatic Routing Management feature is standard with all BPX and IGX switches. The network
automatically detects trunk failures and routes connections around the failures.
