SNMPv3: master auth and privacy keys#

Send SNMP GET request using the following options:

with SNMPv3, user ‘usr-md5-des’, MD5 authentication, DES encryption
use master auth and privacy keys instead of pass-phrase
over IPv4/UDP
to an Agent at demo.pysnmp.com:161
for SNMPv2-MIB::sysDescr.0 MIB object instance

Functionally similar to:

$ snmpget -v3 -l authPriv -u usr-md5-des -3m 0x1dcf59e86553b3afa5d32fd5d61bf0cf -3M 0xec5ab55e93e1d85cb6846d0f23e845e0 demo.pysnmp.com SNMPv2-MIB::sysDescr.0

SNMPv3: localized auth and privacy keys#

Send SNMP GET request using the following options:

with SNMPv3, user ‘usr-md5-des’, MD5 authentication, DES encryption
use localized auth and privacy keys instead of pass-phrase or master keys
configure authoritative SNMP engine ID (0x0000000000 can be used as well)
over IPv4/UDP
to an Agent at demo.pysnmp.com:161
for SNMPv2-MIB::sysDescr.0 MIB object instance

Functionally similar to:
