What Is CISCO-MGX82XX-CARD-FEATURE-MIB?

CISCO-MGX82XX-CARD-FEATURE-MIB is a Cisco-specific MIB module that describes feature support on the controller cards of the Cisco MGX 8200-series multiservice WAN switching platform, specifically the PXM (Processor Switch Module) controller in the MGX8250 and the ASC (AXIS Shelf Controller) in the MGX8220. It exposes configuration-oriented data such as which VSI (Virtual Switch Interface) controllers (e.g., PNNI, MPLS) are permitted on the switch core, connection admission control (CAC) modes, APS protection-switching attributes, and card redundancy settings. Though primarily a configuration/capability MIB rather than a live-counter MIB, it is used to monitor the operational state and feature availability of controller hardware -- confirming whether redundancy and CAC are enabled on a given card is effectively a hardware-health/configuration-status check. It is one of a family of Cisco MGX8200 MIBs and depends on general Cisco chassis/card enumeration conventions for identifying which physical card a given feature setting applies to. It is deployed in carrier and enterprise WAN environments where Cisco MGX 8220/8250 switches provide ATM/Frame Relay/VSI-controlled multiservice switching. Engineers can download the CISCO-MGX82XX-CARD-FEATURE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-MGX82XX-CARD-FEATURE-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Cisco MGX 8250 WAN switch (PXM controller card)
Cisco MGX 8220 WAN switch (ASC controller card)

Monitoring Examples

An administrator polling ascFeatures or pxmFeatures can confirm which optional features are active on an ASC or PXM controller card, while switchCoreCard and redundancyAllowed reveal whether the card is configured for redundant operation. Checking trkCACEnable and pxmCardCacMode across trunks shows whether connection admission control is protecting against oversubscription -- an unexpectedly disabled CAC mode would flag a capacity-risk misconfiguration. vsiControllersAllowed and apsCardAttributes would be read to verify VSI controller capacity and APS protection support on the card.

What Can Be Monitored

VSI controller allowance
connection admission control (CAC) mode
card redundancy configuration
APS card attributes
ASC/PXM feature support

OID symbolic	OID numeric	Type	Access	Description
I32 apsCardAttributes	1.3.6.1.4.1.351.110.3.15.2	Integer32	read-only	This respesents bit map of the APS card attributes supported. The bit position supported are: BITs 0, 1 - unused BIT 2 - APS standard protocol configured (1 = TRUE ; 0 = FALSE) BIT 3, 4 ,5 - unused BIT 6 - Card HW supports APS 1+1 on two cards (1 = TRUE ; 0 = FALSE) BIT 7 - Card FW supports APS (1 = TRUE ; 0 = FALSE) Remaining bits are set to 0.
ascFeatures	1.3.6.1.4.1.351.110.3.5
ciscoMgx82xxCardFeatureMIB	1.3.6.1.4.1.351.150.74			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.
cmAscCardFeatureGroup	1.3.6.1.4.1.351.150.74.2.1.2			The collection of objects which are used to represent Axis Shelf Controller(ASC) Features.
cmCardFeatureCompliance	1.3.6.1.4.1.351.150.74.2.2.1			The compliance statement for objects related to Frame Relay Ports.

INT pxmCardCacMode	1.3.6.1.4.1.351.110.3.15.4	INTEGER	read-write	This object identifies the CAC mode set on a card. If this is set to pcrBasedCAC(1) then the CAC calculations will be done based on PCR on the connection. If this set to scrBasedCAC(2) then the CAC calculations are done based on the scr of the connections. This will be applicable only if CAC is enabled (i.e trkCACEnable is set to enable(2)).

INT redundancyAllowed	1.3.6.1.4.1.351.110.3.5.1	INTEGER	read-only	This object identifies whether redundancy is allowed in MGX82XX shelf.
INT switchCoreCard	1.3.6.1.4.1.351.110.3.20.1	INTEGER	read-write	This object is used for performing switchover of core card set. The core card set includes Controller Card and Service Redundancy Module(SRM). The possible values are : noAction (1): No operation doswitchcc (2): Perform switchover operation instswitchcc (3): Perform switchover operation fallbackswitchcc(4):
INT trkCACEnable	1.3.6.1.4.1.351.110.3.15.3	INTEGER	read-write	This MIB variable allows to add a new connection on the feeder trunk even if it is over-subscribed.

The bit positions are : BIT 0 - PAR(Portable AutoRoute Controller) BIT 1 - PNNI(Private network to network Interface) BIT 2 - TAG(Tag Switching or MPLS Controller) (e.g. A value of 1 in BIT 0 indicates the presence of PAR ) Remaining bits are set to 0.
