"""
Fetch scalar and table variables
++++++++++++++++++++++++++++++++
Send a series of SNMP GETBULK requests using the following options:
* with SNMPv3 with user 'usr-md5-des', MD5 auth and DES privacy protocols
* over IPv6/UDP
* to an Agent at [::1]:161
* with values non-repeaters = 1, max-repetitions = 25
* for IP-MIB::ipAdEntAddr and all columns of the IF-MIB::ifEntry table
* stop when response OIDs leave the scopes of the table
Functionally similar to:
| $ snmpbulkwalk -v3 -lauthPriv -u usr-md5-none -A authkey1 -X privkey1 \
| -Cn1, -Cr25 \
| demo.snmplabs.com \
| IP-MIB::ipAdEntAddr \
| IP-MIB::ipAddrEntry
