SNMP Protocol: Understanding the Protocol SNMPv2 messages GetRequest (port 161) Get estimation of one or more MIB article cases GetNextRequest (port 161) Get estimation of next MIB object case in rundown or table GetBulkRequest (port 161) Get values in expansive piece of information, for instance InformRequest (port 161) Inform remote overseeing substance of MIB qualities remote to its entrance SetRequest (port 161) Set estimation of one or more MIB item occasions Response (port 162) Generated in light of above solicitations. SNMPv2-Trap (port 162) Inform chief of an extraordinary occasion

Lab. 1 : NET-SNMP introduce and arrangement Installing snmp apparatus on Linux or Unix stage Now your host is SNMP specialist Understanding SNMP message by utilizing fundamental SNMP director application NET-SNMP NET-SNMP

Slide 10

Lab. 1 : NET-SNMP introduce and design NET-SNMP (http://www.net-snmp.org) Widely utilized free SNMP apparatus ( on Linux stage or others ) Formerly known as CMU-SNMP and UCD-SNMP Providing the followings Basically mib-2 module and other private mib moudules SNMP specialist ability Simple SNMP director application Many C APIs to create SNMP operator and chief

Slide 11

Lab. 1 : NET-SNMP introduce and design 1> Install ( On Linux stage ) You *must* download net-snmp v. 5.0 . After "./arrange", "make" and "make introduce" , you can execute specialist daemon. #/usr/nearby/sbin/snmpd From now this host is a SNMP operator. Projects and libraries are situated in the accompanying catalogs/usr/nearby/receptacle,/usr/neighborhood/sbin/,/usr/neighborhood/offer/snmp,/usr/neighborhood/lib 2> Configuration ( not as a matter of course for this lab .) execute/usr/nearby/container/snmpconf for design .conf records (/usr/neighborhood/offer/snmp/) snmpd.conf : snmp specialist arrangement snmptrapd.conf : daemon setup accepting operator trap message snmp.conf : snmp application arrangement

Slide 12

Lab. 1 : NET-SNMP introduce and arrangement 3> Using essential SNMP supervisor applications utilization case snmpget : by the SNMP GET_Request message execute snmpgetnext, snmpwalk, snmptable, snmpset, snmptest, snmpstatus [/home]# snmpget mcl.kaist.ac.kr sysUpTime.0 - c open RFC1213-MIB::sysUpTime.0 = Timeticks: (116730897) 13 days, 12:15:08.97

Lab. 2 : Management Information Exchange amongst Agent and Manager by means of SNMP MG-Soft MIB Browser NET-SNMP NET-SNMP

Slide 14

Lab. 2 : Management Information Exchange amongst Agent and Manager by means of SNMP 1> Use of MG-Soft MIB Browser (MG-Soft MIB Browser)

Slide 15

Lab. 2 : Management Information Exchange amongst Agent and Manager by means of SNMP 2> Manager Implementation (NET-SNMP) Step A) Read and comprehend the \'Programming a Simple Application\' part on the site. URL: http://www.net-snmp.org/instructional exercise/instructional exercise 5/toolbox/Step B) Read and comprehend the \'Programming a Synchronouse/Asynchronous Application\' part on the site URL: http://www.net-snmp.org/instructional exercise/instructional exercise 5/tool compartment/Step C) Write a system seeking SNMP operators in a given scope of IP locations.

Slide 16

Lab. 2 : Management Information Exchange amongst Agent and Manager by means of SNMP Step C) Write a project seeking SNMP operators in a given scope of IP locations. Clue 1 : Understand the projects for Step An and B quickly. Clue 2 : You can check SNMP specialist alive Request any item variable for the operator Check mistake message for the reaction

Slide 17

Lab. 2 : Management Information Exchange amongst Agent and Manager by means of SNMP 3> Adding a New MIB Module in Agent (MG-Soft MIB Browser) Step 1) A "MicrowareOven" MIB module is given. Step 2) Compile the MIB module utilizing MG-Soft MIB compiler. Allude to the \'MIB Compiler User Manual\' material. Step 3) Add the MIB module to MG-Soft MIB program. Step 4) Check the MIB module in the MIB tree of MG-Soft MIB program.

Lab.3 : Web-based Network Management Web-based Network Management utilizing CGI Management Station Web Browser NET-SNMP : Agent HTTP Management Server Http Server SNMP Manager NET-SNMP : Manager

Slide 19

Lab.3 : Web-based Network Management 1> Programming a CGI script Web based "snmpget" execution HTML interface structure You can utilize any CGI script dialect.

Slide 20

Pre report and Main Report Pre report 1> What are the five regions of system administration characterized by the ISO? 2> Briefly portray CMIP, and quickly contrast SNMP with CMIP. 3> Briefly depict SNMP for different rendition. 4> Describe system administration model (Organization Model, Information Model, Communication Model and Functional Model). Allude to the section 6 on the site (sharp.kaist.ac.kr/~ccna4). Primary report 1> Follow above lab 1,2,3 and portray the outcome 2>Describe different system administration models (Centralized/Hierarchical/Distributed Network Management Architecture). Allude to the part 6 on the site (sharp.kaist.ac.kr/~ccna4).
