This needs to be done on a per-application basis.

Select the application, show package content, edit the plist.info and add:

  ...
  <dict>
  ...
  ...
  <key>LSUIPresentationMode</key>

The bare minimum you need to query an SNMP service

To traverse the tree of public data (i.e. "public" community), starting from the "iso" root:

  snmpwalk -v 2c -Cc -c public -m ALL 10.0.0.1 iso

To print out private data ("private" community, enterprises leaf(1.3.6.1.4)):

snmpwalk -v 2c -c private -l authPriv -u "user" -a MD5 -A "pass" -x DES -X "pass" -m ALL 10.0.0.1 1.3.6.1.4
