cnfpart
Configure Resource Partition—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
Modifies a resource partition. A resource partition on the AXSM consists of minimum and maximum
percentages of bandwidth, a VPI/VCI range, and a minimum and maximum number of connections
available to a network control application. The current network controller is PNNI. Refer to the
description of addpart for information on resource partitions.
You must bring the port down using dnport before you can configure a partition using cnfpart.
Note The cnfpart and cnfrscprtn commands are identical. The name “cnfrscprtn” is consistent with the
corresponding command in a Cisco MGX 8850 PXM1-based switch. You can use either command.
Note On the AXSM-E and AXSM-XG, the VPI/VCI range can not be modified.
Important VPI/VCI Range Issues
When configuring a partition, be sure to configure the VPI/VCI ranges to meet your actual usage
requirements. It is important that you do not configure the entire VPI/VCI range for a single partition.
The ability to seamlessly add new partitions in the future depends on configuring only the necessary
ranges for each partition.
The Cisco recommended ranges for a single partition are as follows:
• For a VPI on a UNI port where the available range is 0–255, the recommended configured range is
0–140.
• For a VPI on a PNNI port where the range is 0–4096, the recommended configured range is 0–2500
or about 60%.
Caution When adding or configuring a PNNI partition, do not configure the entire VPI/VCI range for one
partition. In the future, if you migrate from a PNNI only service to a PNNI/MPLS service with multiple
partitions, you will need the additional VPI/VCI ranges to be able to add a new partition. If you configure
all of the available ranges for the PNNI partition, you will not be able to add a new MPLS partition
without bringing down the port using the dnport command to change the PNNI VPI/VCI ranges.
Bringing down a port on a live network is usually not an option.
