Hello.
The Dude and SNMP on cisco Sx300, Sx500 does't work. Can you fix it? THX.

snmpwalk works fine.

This priblem persist on Dell powerconnect, huawey, alcatel switches.
If you will find out the method to work please let us know.
Dude monitors about 100+ devices, on 750gr3 board.

ROS 6.38.5
My Netgear GS724T switch doesn't show results in the SNMP tab. But if you use the tools menu to launch SNMP walk all values are shown. Just the same as the OP. At the same time a Samsung Laser printer responds correctly in the SNMP tab.

Use 6.37.5 - it works fine with SNMP.

Mikrotik developers, please, check this problem. I test every release (till 6.37.5 to 6.39.2) - SNMP on DELL switches (we don't use Cisco, so can't test on it) does NOT work.
