What I configured in snmpd.conf file *engineID 8000b85c03d0672649a01e*
NetSNMP converted the above engineID in to equivalent Hex value for each character, i.e (8000b85c03d0672649a01e => 38 30 30 30 62 38 35 63 30 33 64 30 36 37 32 36 34 39 61 30 31 65) with some prefix *0x80001f8804* *snippet:* usmUser 1 3 0x80001f880438303030623835633033643036373236343961303165 "testv3user" "testv3user" NULL .1.3.6.1.6.3.10.1.1.2 0x055a6d2afcff5cb7a22c3a9c61b55c08 .1.3.6.1.6.3.10.1.2.4 0x055a6d2afcff5cb7a22c3a9c61b55c08 "" engineBoots 8 *oldEngineID 0x80001f880438303030623835633033643036373236343961303165* when I do snpwalk with "-e 8000b85c03d0672649a01e" walk failed. Where as snmpwalk works fine with (-e 0x80001f880438303030623835633033643036373236343961303165) I was expecting snmpwalk to work with "-e 8000b85c03d0672649a01e", this is the engineId that I configured in snmpd.conf file.
