Planning for Controller Resources
Controllers require a free bandwidth of at least 150 cells per second (cps) to be reserved for signaling
on the IGX port. If a minimum of 150 cps is not available on the port, the switch software command
addctrlr is not executed. To calculate free bandwidth, use the following equation:
free bandwidth = port speed - PVC maximum bandwidth -VSI bandwidth
In some cases, you may need to change the bandwidth allocated to AutoRoute to obtain a free bandwidth
of 150 cps. Use the switch software command, cnfrsrc, to reallocate bandwidth on a port.
VSI Configuration
Note While you can add a controller to a UXM interface without configuring a VSI partition on that same
interface, you will not be able to use the interface for VSI connections without also configuring a VSI
partition. For example, MPLS controllers XTAG interfaces support includes setup of a tag-control-VC
between the hosting interface and the XTAG interface. This VC is a VSI connection, so the controller
cannot configure the connection unless the hosting interface has a VSI partition.
When configuring a node for VSI, complete the following steps:
Step 1 Plan your resources (see the “Logical Switch Partitioning and Allocation of Resources” section on
page 10-36).
Step 2 Using the switch software commands uptrk, upln, and upport, activate the desired trunk, line, and port
for the configured partition.
Step 3 Using the switch software command cnfrsrc, configure partition resources on the active interface (see
Table 10-10 for command parameters).
Tip The VPI range is of local significance, and do not have to be the same for each port in a node. However,
for tracking purposes, Cisco recommends keeping the VPI range the same for each port in the node.
