Description: The MIB module which describes the features supported in MGX82XX products. This MIB Module provides the features supported in Controller Cards in MGX8250 and MGX8220.

Terminologies used:

PXM : Processor Switch Module. This is controller card in MGX8250. ASC : AXIS Shelf Controller. This is controller card in MGX8220. VSI : Virtual Switch Interface, a hardware-independent switch control protocol. This allows a Switch to be controlled by a multiple controllers such as PNNI, MPLS. These control planes can be internal or external to the switch.The VSI interface defines the messages and associated functions which allow communication between the controller and the switch.This interface is expected to support all types of connections (voice,data,frame relay,ATM) for PVCs, SPVCs and SVCs.

Controller - Software ( and possibly hardware) which manages topology and network resources and performs VSI Master function. This performs source routing for end-to-end SVCs, including general call acceptance GCAC,setup calls with other controllers. PNNI and MPLS are examples of controllers.
