SNMPv3: auth SHA, privacy AES128
++++++++++++++++++++++++++++++++
Send SNMP GET request using the following options:
* with SNMPv3, user 'usr-sha-aes', SHA authentication, AES128 encryption
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* for SNMPv2-MIB::sysDescr.0 MIB object
Available authentication protocols:
#. USM_AUTH_HMAC96_MD5
#. USM_AUTH_HMAC96_SHA
#. USM_AUTH_HMAC128_SHA224
#. USM_AUTH_HMAC192_SHA256
#. USM_AUTH_HMAC256_SHA384
#. USM_AUTH_HMAC384_SHA512
#. USM_AUTH_NONE
Available privacy protocols:
#. USM_PRIV_CBC56_DES
#. USM_PRIV_CBC168_3DES
#. USM_PRIV_CFB128_AES
#. USM_PRIV_CFB192_AES
#. USM_PRIV_CFB256_AES
#. USM_PRIV_NONE
Functionally similar to:
| $ snmpget -v3 -l authPriv -u usr-sha-aes -A authkey1 -X privkey1 -a SHA -x AES demo.snmplabs.com SNMPv2-MIB::sysDescr.0
