Simple Network Management Protocol for monitoring of managed/un-managed

supported.
Windows SNMP Service must be installed and configured. The security settings
of the computer must allow the transmission and reception of ICMP (Internet

| MIB Storage Directory |
Store MIB files for each device to this
directory. On device startup, if device MIB file is empty
the driver will import the MIB (Management Information Base) from the device, otherwise the MIB is
loaded from the file. All objects including traps will be save to the file on device shutdown, or when new traps are reported. |
| MIB Import Directory |
All files in this directory will be used to
translate Object Identifiers to names. Email us these files and all the files in the
MIB Storage Directory if you want us to incorporate these files into
the SNMP driver in future releases. |

the range of IP addresses.

Click on the first tab of this port to see the
progress of the search. Up to 65535 IP addresses can be searched at
any one time.
