12.5 Using the OSA-Express SNMP subagent
The OSA-Express Simple Network Management Protocol (SNMP) subagent (osasnmpd)
supports Management Information Bases (MIBs) for OSA-Express features in QDIO mode
only. You can use traditional snmp commands to obtain MIB information from the new Direct
SNMP MIB, also called the
OSA-Express Enterprise Specific MIB. The MIBS.DATA file
provides the mapping of the names of the OSA tables and objects to their SNMP object
identifiers (OIDs). The query function is supported using the SNMP “get” command, and is
used to obtain real time device specifying information, such as operational status and traffic
12.5.1 Obtaining and configuring osasnmpd
This section outlines the steps to obtain and configure the OSA-Express SNMP subagent. Be
aware that this sample configuration does not take security-related requirements into
account. For details, consult Device Drivers, Features, and Commands for the April 2004

Download the IBM OSA-Express MIB
The OSA-Express SNMP subagent requires you to download the IBM OSA-Express MIB.
This MIB file is valid only for the OSA-Express adapter, and you can obtain it from IBM
1. Sign in IBM Resource Link at:
A user ID and password are required. You can apply for a user ID if you do not yet have
one, or use an existing user ID.
2. Select Library from the left-hand navigation area.
3. Under Library shortcuts, select Open Systems Adapter (OSA) Library.
4. Follow the link for OSA-Express Direct SNMP MIB module.
5. Select and download the MIB for your Licensed Internal Code (LIC) level. This example
uses the osa10gig.mib.
6. Rename the MIB file to the name specified in the MIBs definition line. In this example, the
definition line in the MIB is:
==>IBM-OSA-MIB DEFINITIONS ::= BEGIN
Then, this example renames the MIB to IBM-OSA-MIB.txt.
7. Place the MIB file in /usr/share/snmp/mibs directory and change file permission to 644.
Note: An SNMP management application, such as Tivoli NetView®, can use an SNMP for
OSA-Express. This feature is currently
not supported for OSA-Express adapters
connected to a z/VM Virtual Switch (VSWITCH).
Note: If you use a different directory, be sure to specify the changed directory in the
