Resource Partitioning
BXM SVC Resource Partitioning
A BXM card used as a UNI port can be configured to support ATM SVCs. The BXM will have to
be added and upped like a standard PVC port. The BXM port will have to upped as a line (upln) to
function as a UNI port.
Note The initial command to up a trunk (uptrk) or to up a line (upln) on the BXM configures all
the physical ports on a BXM card to be either trunks or ports. They can not be inter-mixed.
For additional information on using the BPX switch command line interface and applicable
commands, refer to the Cisco WAN Switching Command Reference manual. These procedures will
concentrate on those commands that are specific to SVC resource partitioning.
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. The following resources must
be partitioned:
• SVC Channels
• SVC VPI Min
• SVC VPI Max
• SVC Bandwidth
• SVC Queue Pool Size.
To partition the BXM port, follow these steps:
Step 1 Log in to the BPX switch.
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:
