Vsi Configuration Procedures; Adding A Controller - Cisco BPX 8620 Installation And Configuration Manual

VSI Configuration Procedures

VSI Configuration Procedures
In the VSI control model, a controller sees the switch as a collection of slaves with their interfaces. The
controller can establish connections between any two interfaces. The controller uses resources allocated
to its partition.
Each VSI interface can be assigned a default Class of Service template upon activation. Use the switch
software CLI or Cisco WAN Manager to configure a different template to an interface.
The procedure for adding a VSI-based controller such as the MPLS controller to the BPX is similar to
adding an MGX 8220 interface shelf to the BPX. To attach a controller to a node to control the node, use
the addshelf command.
The VSI controllers are allocated a partition of the switch resources. VSI controllers manage their
partition through the VSI protocol. The controllers run the VSI master. The VSI master entity interacts
with the VSI slave running on the BXMs through the VSI interface to set up VSI connections using the
resources in the partition assigned to the controller.
To configure VSI resources on a given interface, use the cnfrsrc command.

Adding a Controller

To add an MPLS controller to any BXM trunk, use the addshelf command with the V (VSI) option.
To add an SES PNNI controller, use the addshelf command with an X option.
To identify VSI controllers and distinguish them from feeders, use the V (VSI) option of the addshelf
command.
To add a SES PNNI controller to a BPX node through an AAL5 interface shelf or feeder type configured
with VSI controller capabilities, use the addctrlr command.
If you are adding two controllers that are intended to be used in a redundant configuration, you must
specify the same partition when you add them to the node by using the addshelf command.
To add an MPLS controller (or a generic VSI controller that does not need AnnexG protocol), use the
following procedure.
Step 1 Up the trunk by using the uptrk command.
Step 2 Add an MPLS controller by using the addshelf command with feeder type set to "V".
Display the controllers and interface shelves attached to the node by using the dspnode command.
Step 3
Display the VSI controllers on a BPX node by using the dspctrlrs command.
Step 4
Note that addshelf and addtrk are mutually exclusive commands; that is, you can use either addshelf
or addtrk, but not both on the same interface shelf.
