Multiple concurrent queries
+++++++++++++++++++++++++++
Send a bunch of different SNMP GET requests to different peers all at once,
wait for responses asynchronously:
* with SNMPv1, community 'public' and
with SNMPv2c, community 'public' and
* over IPv4/UDP and
over IPv6/UDP
* to an Agent at demo.snmplabs.com:161 and
to an Agent at [::1]:161
* for instances of SNMPv2-MIB::system
SNMPv2-MIB::sysLocation.0 MIB objects
* Enable MIB lookup feature
