Resource Partitioning

A logical switch is configured by enabling the partition and allocating resources to the partition. This
must be done for each of the interfaces in the partition. The same procedure must be followed to define
each of the logical switches. As resources are allocated to the different logical switches a partition of
the switch resources is defined.
The resources that are partitioned amongst the different logical switches are:
•
•
•
Resources are configured and allocated per interface, but the pool of resources may be managed at a
different level. The pool of LCNs is maintained at the card level, and there are also limits at the port
group level. The bandwidth is limited by the interface rate, and therefore the limitation is at the interface
level. Similarly the range of VPI is also defined at the interface level.
