First, configure your Netgear GS710TUP to enable SHA authentication (instead of the less secure MD5 authentication) by opening System -> SNMP -> SNMPv3 , clicking on SHA and clicking Save:
Given that configuration, you can query information such as the switch uptime (which is represented by OID 1.3.6.1.2.1.1.3.0) using snmpwalk:
snmpwalk -v3 -l authNopriv -c public -a SHA1 -u admin -A 'switchAdminPassword' SWITCHIPADDRESS 1.3.6.1.2.1.1.3.0
Remember to replace switchAdminPassword by the admin password of your switch and SWITCHIPADDRESS by the IP address of the switch.
