Extending the IF-MIB
Extending the IF-MIB
The IF-MIB provides basic management status and control of interfaces and sublayers within a network
switch. Multiple standard and Cisco-specific MIBs use ifIndex from the IF-MIB to extend management
for specific interface types. Cisco MIBs also enhance 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 3.
See the Cisco Nexus 5000 CLI Configuration Guide, Release 4.0 for details about enabling link
notifications that use these additional varbinds.
