Cisco MDS 9000 Family MIB Quick Reference
OL-18087-01, Cisco MDS NX-OS Release 4.x
Extending the IF-MIB
Extending the IF-MIB
The IF-MIB provides basic management status and control of interfaces and sublayers within a network
device. Multiple standard and Cisco-specific MIBs use ifIndex from the IF-MIB to extend management
for specific interface types. Cisco MIBs also enhances the two interface notifications, linkUp and
linkDown, from the IF-MIB to provide a clearer indication of the reason for these notifications. Cisco
MIBs add up to two varbinds to linkUp and linkDown as shown in Table 22.
Refer to the Cisco MDS 9000 Family CLI Configuration Guide for details about enabling link
notifications that use these additional varbinds.
CISCO-ENTITY-EXT-MIB
Extends the entityPhysicalTable for modules with
processors. For each of these modules, this MIB provides
memory statistics and LED information.
CISCO-ENTITY-FRU-CONTROL-MIB
Manages field-replaceable units, such as power supplies,
fans, and modules.
CISCO-ENTITY-SENSOR-MIB
Provides sensor data for environmental monitors such as
temperature gauges.
CISCO-FC-ROUTE-MIB
Provides ingress traffic counters for Fibre Channel, linked to
entPhysicalIndex.
CISCO-IMAGE-UPGRADE-MIB
Provides module image management based on
entPhysicalIndex.
CISCO-VIRTUAL-NW-IF-MIB
Maps VSAN ID to FC ID and ifIndex, based on
entPhysicalIndex.
