IP Service Provisioning
When a trunk is activated, the entire bandwidth is allocated to AutoRoute. To change the allocation to
provide resources for a VSI, use the cnfrsrc command on the IGX switch.
You can configure partition resources between AutoRoute PVCs and three VSI LSC controllers. Up to
three VSI controllers in different control planes can independently control the switch without
communication between controllers. The controllers are unaware of other control planes sharing the
switch because different control planes use different partitions of the switch resources.
The following limitations apply to multiple VSI partitioning:
• Up to three partitions are supported.
• Resources can be redistributed among different VSI partitions.
• Resources allocated to a partition: LCNs, bandwidth, and VPI range.
• Resources are allocated to AutoRoute. These resources can be freed from AutoRoute and then
allocated to VSI.
• No multiple partitions on virtual trunks. A virtual trunk is managed by either AutoRoute or by a
single VSI partition.
• A VSI partition is local to the IGX switch and not network wide.
Multiple Partition Example
Each logical switch represents a collection of interfaces, each with an associated set of resources.
The following example is an IGX switch with four interfaces:
• 10.1
• 10.2.1
• 11.1
• 11.7.1
See Example 10-1 for the interface configurations for Figure 10-15. See Table 10-13 for an example
with three partitions enabled.
Figure 10-15 Virtual Switches
To display the partitioning resources of an interface use the dsprsrc command as in Example 10-1.
