SNMP
–
Read-write—Indicates that instance of the object may be read or written, but not created
–
Read-only—Indicates that instances of the object may be read but not written or created
–
Accessible-for-notify—Indicates that instances of the object may only appear in notifications
–
Not-accessible—Indicates that instances of the object may not be directly read, written, or
created
•
Status—The status of a managed object can be:
–
Mandatory—Indicates that the definition is required and should be implemented
–
Current—Indicates that the definition is current
–
Deprecated—Indicates that the definition will soon be made obsolete and need no longer be
implemented
–
Obsolete—Indicates that managed nodes should not implement the object
•
Description—Provides a textual description of the managed object
The following is an example of a MIB object:
tpTDMIfCollectTimeInterval OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
This object shows measurement time interval seconds.
::= {tpTDMIfStatTableEntry 1}

SNMP
Cisco MIB variables are accessible through SNMP, which is an application-layer protocol designed to
facilitate the exchange of management information between network devices.
Instead of defining a large set of commands, SNMP places all operations in a get-request,
get-next-request, or set-request format. For example, an SNMP manager can get a value from an SNMP
agent or store a value in that SNMP agent. The SNMP manager can be part of an NMS, and the SNMP
agent can reside on a networking device such as a router. You can compile the Cisco MIB with your
network management software. If SNMP is configured on a Catalyst Switch, the SNMP agent can
respond to MIB-related queries being sent by the NMS.
An example of an NMS is the CiscoWorks network management software. CiscoWorks uses the Cisco
MIB variables to set device variables and to poll devices on the internetwork for specific information.
The results of a poll can be displayed as a graph and analyzed for the troubleshooting of internetwork
problems. Results can also be used to increase network performance, verify the configuration of devices,
monitor traffic loads, and so on.
