Learning Objectives

·         Configure SMTP on router.

·         Verify MIB tree from a client.

Introduction

Router R1 is running SNMP client and you can observe the MIB tree from PC1.

Step 1. Test Connectivity

·         Ping from PC1 to R1.

·         Ping from Server0 to R1.

Step 2. Configure R1 as SMTP client. comm is the community string.

R1(config)# snmp-server community comm RO

Step 3. View the MIB tree.

·        Click on PC1.

·        Open MIB browser from the Desktop tab.

·        Address should be 192.168.1.1.

·        Click Advanced and enter comm for Read community and select SNMP version v2.

·        Expand the tree on the left hand side under SNMP MIBs, MIB Tree -> router_std MIBs -> .iso -> .org -> .dod -> .internet -> .mgmt -> .mib-2 -> .system -> .sysDescr

·        Observe OID. It should be .1.3.6.1.2.1.1.1.0.

·        Choose Get and click on GO

·        Switch to the Simulation mode and choose only SNMP from Edit Filters button.

·       Click on capture button and observer the packet travel.

·       Click on the packet and observe that SNMP is layer 7.

·       Now go back to MIB browser of PC1 and observe the Result table.

Step 3. Check results.

Your completion percentage should be 100%. Click Check Results to see feedback and verification of which required components have been completed.
