"""
Fetch fixed amount of MIB variables
+++++++++++++++++++++++++++++++++++
Send a series of SNMP GETNEXT requests using the following options:
* with SNMPv3, user 'usr-sha-aes128', SHA auth, AES128 privacy
* over UDP/IPv4
* to an Agent at demo.snmplabs.com:161
* for all OIDs past SNMPv2-MIB
* run till end-of-mib condition is reported by Agent OR maxRows == 100
* ignoring non-increasing OIDs whenever reported by Agent
Functionally similar to:
| $ snmpwalk -v3 -lauthPriv -u usr-sha-aes128 -A authkey1 -X privkey1 -a MD5 -x AES demo.snmplabs.com SNMPv2-MIB::system
