Chapter24 Configuring BXM Virtual Circuits
BXM SVC Resource Partitioning
For information on MPLS Switching, refer to Cisco MPLS Software Configuration Guide.
A BXM card used as a UNI port can be configured to support ATM SVCs. You will need to:
• Add the BXM and activate it (up it) like a standard PVC port.
• Up the BXM port as a line (upln) to function as a UNI port.
Note The initial command to up a trunk (uptrk)ortoupaline(upln) on the BXM configures
all the physical ports on a BXM card to be either trunks or ports. They can not be
intermixed.
Before partitioning SVC resources, you must determine which BXM UNI ports will support ATM
SVCs. The BXM must have its resources partitioned to support SVCs.
These resources must be partitioned:
• SVC Channels
• SVC VPI Min
• SVC VPI Max
• SVC Bandwidth
• SVC Queue Pool Size
For additional information on using the BPX switch command line interface and applicable commands,
refer to the Cisco WAN Switching Command Reference. These procedures will concentrate on those
commands that are specific to SVC resource partitioning.
To partition the BXM port, follow these steps:
Step 1 LogintotheBPXswitch.
Step 2 Using the upln and upport commands, up the line and port which is going to be connected to ATM CPE.
Step 3 Make sure the port is configured as UNI.
Step 4 Enter the cnfport <port num> command, shown in the following example:
