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:

Example: BNI cnftrk Command

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:
