How do I use a SNMP MIB browser to monitor the status of all NPorts in a network?

The MIB browser is installed on a host computer in the network.


To use the iReasoning MIB Browser on the host computer to monitor an NPort device on the same network, do the following:

  1. Open the MIB browser and click on the File tab. Select Load MIBs.

  2. Browse to the mibs folder and select RFC1213-MIB.

  3. Enter the NPort’s IP address in the Address field of your MIB browser.

  4. Select the OID (Object Identifier) of interest.


    You can use the RFC1213 MIB to get the total number of octets transmitted out of/received on the interface, the connection status, and the connected IP addresses.
    • The transmit and receive OIDs are available at:

      Interface > ifTable > ifEntry > ifInOctets/ifOutOctets

    • The connection status and connected IP address OID is available at:

      tcp > tcpConn Table > tcpConnEntry > tcpConnState (OID:.

    For additional details on the RFC1213 and RFC 1317 MIBs, refer to the following links:
