Cisco Systems 8600 Series manual NNI Trunk SVC Resource Partitioning

Resource Partitioning

Step 5 Configure the SVC Channels, SVC VPI Min, SVC VPI Max, and SVC Bandwidth as desired.

Step 6 Next you need to configure the SVC Port Queue depth with the cnfportq <portnum> command shown in the following example.

Example: BXM cnfportq Command

This Command: cnfportq 13.1

SVC Queue Pool Size [5000]:

Step 7 Configure the SVC Queue Pool Size parameter to a value greater than 0 (zero); the default is 0 and needs to be changed for SVCs to operate.

Step 8 Partition the SVC resources for every BXM which is to support ATM SVCs in the BPX switch.

NNI Trunk SVC Resource Partitioning

The BPX switch has two types of trunk cards which may have their resources partitioned to support SVCs.

BNI

BXM

Note It is important to reserve the maximum number of channels before SVCs or PVCs are in use, because SVC partitioning parameters may not be changed if any SVC or PVC is in use on the entire card.

BXM T3/E3, 155, and 622 6-45
