| MIB Storage Directory |
Store MIB files for each device to this directory.

All objects including traps will be save to the file on device shutdown, or when new traps are reported. |

AllTrap will capture all traps from this device.
The scan rate is controlled by the OPC client Group Update interval.
Traps received are under "Trap".
The ios.org.dod.internet.mgmt.mib-2 and iso.org.dod prefixes are suppressed to make browsing more convenient.
Multiple reads and writes
Port Max Input Queue Length controls the maximum number of read or write requests that can be packed into each read or write request. |
