What is the difference between oid and mib

Your apartment or house address indicates a specific location by country, state, city, zip code, street, and house number. A MIB object holds the structure of the network alarms being monitored like a map of the "city" , and it uses the OIDs to keep track of the individual components like the address to a house or other location. The fire department would have to look that up in its MIB to determine the correct street address.

The OID allows the MIB to translate the location of the event into a status description for your network administrators. While it may look daunting, the OID follows a simple structure, with each "dot" segment identifying a part of a network element. Going back to the home address example, the beginning of the Object Identifier tells us the hemisphere of the world, the country, state, city, zip code, street address and eventually leads us to our driveway.

In the above OID, the specific "driveway" is With this structure, very specific elements can be identified and located even in very complex networks. This allows the SNMP manager to produce messages that can be read by people. The MIB will decode the address and attach a text description to it. This allows the SNMP Manager to present the value of the alarm condition with the identifying description of the labeled alarm.

So for example, let's say the SNMP Manager wants to know if there is a car in the driveway of your house a "yes or no" question, often referred to as a discrete alarm in the alarm monitoring world. The driveway or alarm point we want to monitor would be represented by the " " portion of the address. The "value" reported is the current state of the driveway : occupied by a car or not.

For a condition or device to be monitored, it must have a corresponding MIB definition. Earlier versions of SNMP transmit strings in clear-text, raising another security risk. See versions below. See earlier in this article for more information. Supported in v2 and up. See the beginning of this article for more information on MIBs. V2c and up use the term Notifications to refer to a Trap.

See the beginning of this article for more information on OIDs. Examples are Interface status, or CPU utilization. This is the opposite of polling. However multiple versions were developed, none truly addressing the problems with v1. V2c is the most common flavour, and has enhanced protocol handling over v1, resulting in slightly improved operations. However, security is still an issue because it uses plain-text community strings.

For example, if a BEA Tuxedo 8. For a description of the ULOG file, see reference page userlog 3c. These component MIBs are defined in individual reference pages each addressing the MIB for a particular part of the system.

Instead of referring to groups and managed objects, as is common in SNMP terminology, the TMIB defines application resources as classes and attributes. Classes are the administrative class definitions that make up the TMIB.

Each class has a set of attributes that identifies individual items in the class. Examples of TMIB classes are:. The following keywords are used to define a MIB object: Syntax Defines the abstract data structure corresponding to the object type. Access Defines whether the object value may only be retrieved but not modified read-only or whether it may also be modified read-write.

Description Contains a textual definition of the object type. Specifying Object Identifiers In addition to using the "dot-dot" notation, a series of integers separated by dots to describe OIDs, you can also express OIDs by using textual symbols instead of numbers to represent nodes in the path to the object, or by using a combination of both integers and textual symbols.

For example: mgmt. This MIB contains the main information groups for Tuxedo applications, including domains, machines, queues, servers, routing, clients, and services. For a detailed description, see Core MIB. For a detailed description, see Domains MIB. For a detailed description, see Workstation MIB.

The groups include objects for managing queue spaces, queues, messages, and transactions. For a detailed description, see Traps MIB. As an example, a rule-action might specify that when the value of the polled object at OID.
