Chapter 23 Configuring BXM Virtual Switch Interfaces
Overview: How VSI Works
You configure these parameters on a VSI partition on an interface:
• min lcn: guaranteed LCNs for the partition on the interface.
• max lcn: total number of LCNs the partition is allowed for setting up connections on the interface.
•
min bw: guaranteed bandwidth for the partition on the interface.
• max bw: maximum bandwidth for this partition on the interface.
• start vpi: the lower bound of the VPI range reserved for this partition on the interface.
•
end vpi: the upper bound of the VPI range reserved for this partition on the interface.
Partitioning Between AutoRoute and VSI
In addition to partitioning of resources between VSI and AutoRoute, multiple partitioning allows
sub-partitioning of the VSI space among multiple VSI partitions. Multiple VSI controllers can share the
switch with each other and also with AutoRoute.
The difference between the two types of partitioning is that all the VSI resources are under the control
of the VSI-slave, while the management of AutoRoute resources remains the province of the switch
software.
Figure 23-7 Resource Partitioning Between AutoRoute and VSI
These commands are used for multiple partitioning:
•
dspvsipartinfo
display information about the current usage of partition resources.
• dspchuse
displays a summary of the channel distribution in a given slot.
•
dspvsiif
displays the service class template assigned to an interface along with a summary of the resources
allocated to each partition.
• dspvsich
displays the list and information for the LCNs used for VSI control channels, including inter-slave
channels and master-slave controllers for all controllers in all partitions.
