Chapter24 Configuring BXM Virtual Circuits
Configuring BXM Connections
The full ATM address range for VPI and VCI is supported.
To route connections between customer premise equipment and BXM ports:
Step 1 First configure the BXM for port mode.
a. The initial command to up a trunk (uptrk)ortoupaline(upln) on the BXM card configures all
the ports of the card to be either trunks or lines (UNI port access).
b. Afer using the uptrk command at each port, issue the addtrk command to activate a trunk for
network access.
Step 2 Up the 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 port by using the upport command
Step 6 Add the ATM connections by using the addcon command.
Parameters:
• The slot number is the BXM card slot on the BPX switch.
• The port number is one of the ports on the BXM
• the VPI is the virtual path identifier
• the VCI is the virtual circuit identifier.
Connections can be either:
• Virtual Path Connections (VPC)
VirtualPathConnectionsareidentifiedbyan*intheVCIfield.
• Virtual Circuit Connections (VCC)
Virtual Circuit Connections specify both the VPI and VCI fields.
The VPI and VCI fields have significance only to the local BPX switch, and are translated by tables in
the BPX switch to route the connection. Connections are automatically routed by the AutoRoute feature
once the connection endpoints are specified.
Enter the following parameters for the BXM addcon command. Depending upon the connection type,
you are prompted with appropriate parameters:
