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

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.
