About Cisco MIB Files
AGENT-CAPABILITIES
In SNMP, capabilities files provide implementation details for the associated MIB. These files, called
AGENT-CAPABILITIES, list supported conformance groups and any deviations from the MIB as
implemented in the associated software version. For example, the
CISCO-AAA-SERVER-CAPABILITY provides the implementation details for the
CISCO-AAA-SERVER-MIB, as implemented in Cisco Nexus 5000 Series switches.
Note Capabilities files may have implementation details for more than one software release. You need to
match your software release to the corresponding AGENT-CAPABILITIES clause in this file.
About Cisco MIB Files
Cisco MIB files are a set of objects that are private extensions to the IETF standard MIB II. MIB II is
documented in RFC 1213, Management Information Base for Network Management of TCP/IP-based
Internets: MIB-II. Portions of MIB-II have been updated since RFC 1213. See the IETF website
http://www.ietf.org for the latest updates to this MIB.
If your NMS cannot get requested information from a managed switch, such as a Cisco switch, the MIB
that allows that specific data collection might be missing. Typically, if an NMS cannot retrieve a
particular MIB variable, either the NMS does not recognize the MIB variable, or the agent does not
support the MIB variable. If the NMS does not recognize a specified MIB variable, you might need to
load the MIB into the NMS, usually with a MIB compiler. For example, you might need to load the Cisco
private MIB or the supported RFC MIB into the NMS to execute a specified data collection. If the agent
does not support a specified MIB variable, you must find out what version of system software that you
are running. Different software releases support different MIBs.
Note Cisco and IETF MIBs are updated frequently. You should download the latest MIBs from Cisco.com
whenever you upgrade Cisco Nexus 5000 Series switches.

Cisco MIB File Directories
You can find Cisco MIBs at the following URL:
http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml
Cisco MIB files are organized into two directories: SNMPv1-SMI MIBs are in the SNMPv1 directory
and SNMPv2-SMI MIBs are in the SNMPv2 directory. Cisco also includes supported IETF-standard
MIBs at this website. Use this support list to access and download the individual MIB files.
