Resource Partitioning
BNI Trunk SVC Resource Partitioning
When the BNI is used as a trunk in a BPX switch network, it will have to have its resources
partitioned to support SVCs. Complete details on using the BPX switch command line interface and
applicable commands are described in the Cisco BPX 8600 Series Reference and WAN Switching
Command Reference manuals. These procedures will concentrate on those commands that are
specific to SVC resource partitioning.
The following BNI trunk resources must be partitioned for SVCs:
• SVC Channels
• SVC VPI Min
• SVC VPI Max
• SVC Bandwidth
• SVC Queue Pool Size.
To partition the BNI trunk resources, follow these steps:
Step 1 Log in to the BPX switch
Step 2 Up the trunk with uptrk <trunk_num> command.
Step 3 Enter the cnftrk <trk num> command as shown in the following example:

Step 4 Configure the SVC Vpi Min, SVC Channels, and SVC Bandwidth as desired.
Step 5 Next configure the SVC Queue depth with cnftrkparms <trunk_num> command shown
in the following example:
