Fetch two OID branches
++++++++++++++++++++++
Send a series of SNMP GETNEXT requests using the following options:
* with SNMPv2c, community 'public'
* over IPv4/UDP
* to an Agent at demo.snmplabs.com:161
* for two OIDs in string form
* stop when response OIDs leave the scopes of initial OIDs
Functionally similar to:
| $ snmpwalk -v2c -c public demo.snmplabs.com 1.3.6.1.2.1.2.2.1.2 1.3.6.1.2.1.2.2.1.3
"""#
