Chapter 23 Configuring BXM Virtual Switch Interfaces
Overview: How VSI Works
Three virtual switches are defined by this configuration:
• AutoRoute:
10.1: 2000 lcns, 20000 cps, vpi: 1–199;
10.2.1: 10000 lcns, 10000 cps, vpi 200;
11.1: 2000 lcns, 100000 cps, vpi: 1–199}
•
Partition 1:
10.1: 4000 lcns, 30000 cps, vpi: 200–239;
11.1: 3000 lcns, 50000 cps, vpi: 200–249;
11.7.1: 5000 lcns, 200000 cps, vpi: 250–250}
• Partition 2:
10.1: 4000 lcns, 20000 cps, vpi: 240–255;
11.1: 4000 lcns, 10000 cps, vpi: 250–255}
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:
• LCNs
• Bandwidth
•
VPI range
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.
