Garry is a network administrator in an organization. He uses SNMP to manage networked devices from a remote location. To manage nodes in the network, he uses MIB, which contain formal descriptions of all network objects managed by SNMP. He accesses the contents of MIB by using a web browser either by entering the IP address and Lseries.mib or by entering the DNS library name and Lseries.mib. He is currently retrieving information from an MIB that contains object types for workstations and server services.
Which of the following types of MIB is accessed by Garry in the above scenario?
Option 1 : DHCP.MIB
Option 2 : LNIMIB2.MIB
Option 3 : WINS.MIB
Option 4 : MIB_II.MIB
1. DHCP.MIB
The DHCP Server MIB highlight gives Simple Network Management Protocol (SNMP) admittance to and control of Cisco IOS Dynamic Host Configuration Protocol (DHCP) worker programming on a Cisco switch by an outside organization the executives gadget.
SNMP is an application-layer convention that gives a message arrangement to correspondence between SNMP supervisors and specialists. SNMP gives a normalized system and a typical language that is utilized for observing and overseeing gadgets in an organization.
SNMP characterizes two principle kinds of substances: supervisors and specialists. The SNMP chief is a framework that controls and screens the exercises of organization has utilizing SNMP. The specialist is the product segment inside a far off systems administration gadget that keeps up the information and reports this information, varying, to the supervisor. The administrator and specialist share a Management Information Base (MIB) that characterizes the data that the specialist can make accessible to the supervisor.
A significant component of SNMP is the ability to create spontaneous warnings from a SNMP specialist. These snare notices are messages making the SNMP chief aware of conditions on the organization. Traps are viewed as a specialist to-director work and a solicitation for affirmation of receipt from the SNMP administrator isn’t needed.
2 . LNMIB2.MIB
Contains object types for workstation and worker administrations
3. WINS.MIB
Windows NT form 4 incorporates a MIB that characterizes objects that screen WINS worker action. This MIB (Wins.mib) is naturally introduced when the WINS Server administration is introduced. It contains around 70 articles for arranging and observing WINS, for example, the quantity of goal demands effectively prepared, the quantity of goal demands that fizzled, and the date and season of last information base replication.
The majority of the WINS arrangement boundaries that are set by altering the Registry may likewise be set by utilizing SNMP. WINS objects in the MIB characterized with read-compose access are designed through a NMS.
4. MIB_II.MIB
The mib_ii.mib Management Information Base (MIB) document was initially made by Microsoft for RFC1213, which is for the board of TCP/IP-based systems administration for a host framework.
The lmmib2.mib document contains the accompanying SNMP object types:
| SNMP object type | Description |
|---|---|
| system | This object contains information on the host system, such as identification and contacts. |
| interfaces | This object contains information on the network interfaces of the host system, the associated configurations, and statistics. |
| at | This object contains Address Translation network information of the host system. |
| ip | This object contains Internet Protocol network information of the host system. |
| icmp | This object contains Internet Control Message Protocol network information of the host system. |
| tcp | This object contains Transmission Control Protocol network information of the host system. |
| udp | This object contains User Datagram Protocol network information of the host system. |
| egp | This object contains Exterior Gateway Protocol network information of the host system. |
| snmp | This object contains Simple Network Management Protocol network information of the host system. |
| Traps | This object contains informational, error, and warning information regarding the network interfaces, protocols, and statistics of the host system. |
