+Walk Agent over IPv6
+++++++++++++++++++++
+
+Send a series of SNMP GETNEXT requests with the following options:
+
+* with SNMPv3 with user 'usr-md5-none', MD5 auth and no privacy protocols
+* over IPv6/UDP
+* to an Agent at [::1]:161
+* for two OIDs in tuple form
+* stop on end-of-mib condition for both OIDs
+
+This script performs similar to the following Net-SNMP command:
+
+| $ snmpwalk -v3 -l authNoPriv -u usr-md5-none -A authkey1 -ObentU udp6:[::1]:161 1.3.6.1.2.1.1 1.3.6.1.4.1.1
