Add Resource Partition—AXSM, AXSM-E, AXSM-32-T1E1-E, AXSM-XG
Add a logical partition of resources for a network controller on a port. Before you add resource
partitions, be sure a plan exists for future developments, such as the addition of a new controller.
Note The addpart and addrscprtn commands are identical. Use the command name that suits you. The same
identification applies to commands that display and delete a resource partition.
A resource partition consists of:
• Guaranteed percentage of bandwidth.
• VPI and VCI ranges. For MPLS (or LSC), Cisco Systems recommends a minimum VCI of 35.
• Guaranteed minimum and maximum number of connections.
Note The maximum number of connections must be greater than 10.
Before adding a resource partition, you must:
• Activate physical lines on the card (upln and optional cnfln).
• Add logical ports to the physical lines (addport and optional cnfport).
• Execute addcontroller on the PXM45 to identify a controller type to the Cisco Virtual Switch
Interface (VSI) and give that controller an ID number. The addrscprtn command takes this
controller ID as an argument.
The primary network control application is PNNI. Plan the partitioning for possible use of MPLS or
other controllers in the future.
Note For VNNIs (virtual trunks), you can configure one VNNI per port and one port per partition. Specify the
VNNI interface type through the addport command.
AXSM-E, AXSM-XG Dependencies
A dependency exists between the addcontroller command on the PXM45 and the addpart
(addrscprtn) command on the AXSM-E and AXSM-XG. Both commands take a controller ID (ctrlr_id)
as an input. Both of these controller IDs must be the same when referring to the same VSI controller.
The sequence for executing these two commands should be as follows:
1. Run addcontroller on the PXM45 to specify the location of the VSI controller.
2. Run addpart (addrscprtn) on the AXSM-E and AXSM-XG to add resource partitions for the VSI
controller.
To support legacy service modules and earlier implementations of VSI, only the following combinations
of controller ID (ctrlr_id) values 1, 2, and 3 and controller type (cntrlrType) values are supported:
• controller ID value 1 and controller type value 1 (PAR)
(Controller type (cntrlrType) is an addcontroller parameter.)
• controller ID value 2 and controller type value 2 (PNNI)
• controller ID value 3 and controller type value 3 (MPLS)
