Chapter 23 Configuring BXM Virtual Switch Interface
VSI Configuration Procedures
This mapping defines a relationship between the template and the interface Qbin’s configuration.
A Qbin template defines a default configuration for the set of Qbins for the logical interface. When a
template assignment is made to an interface, the corresponding default Qbin configuration becomes the
interface’s Qbin configuration.
Once a service template has been assigned, you can then adjust some of the parameters of this
configuration on a per-interface basis. Changes you make to the Qbin configuration of an interface affect
only that interface’s Qbin configuration. Your changes do not affect the Qbin template assigned to that
interface.
To change the template’s configuration of the interface, provide new values by using the cnfqbin
command. The Qbin is now “user configured” as opposed to “template configured.” This information is
displayed on the
dspqbin screen, which indicates whether the values in the Qbin are from the template
assigned to the interface, or whether the values have been changed to user-defined values.
To see the Qbin’s default service type and the Qbin number, execute the dspsct command.
Use the following commands to configure Qbins:
•
cnfqbin
• dspqbin
•
dspqbint
Enabling VSI ILMI Functionality for the PNNI Controller
You need to enable VSI ILMI functionality on VSI-enabled trunk interfaces when using PNNI. Note that
VSI ILMI functionality cannot be enabled on trunks to which feeders or VSI controllers are attached.
To enable VSI ILMI functionality on physical trunk interfaces, use the following procedure.
Step 1
Up a physical trunk by using the uptrk command.
Step 2 Configure the trunk to enable ILMI protocol to run on the BXM card by enabling the “Protocol by the
card” option of the
cnftrk command.
Step 3
Configure a VSI partition on the trunk interface by using the cnfrsrc command.
Step 4
Enable VSI ILMI session for the VSI partition by using the cnfvsipart command.
To enable VSI ILMI functionality on virtual trunk interfaces, use the following procedure.
Step 1
Up a virtual trunk by using the uptrk command.
Step 2
Configure the trunk VPI by using the cnftrk command. (The ILMI automatically runs on the BXM card
for virtual trunks.) This is not configurable by using the cnftrk command.
Step 3 Configure a VSI partition on the virtual trunk interface by using the cnfrsrc command.
Step 4
Enable VSI ILMI functionality for the VSI partition by using the cnfvsipart command.
Note
VSI ILMI can be enabled for only one VSI partition on the trunk interface.
