OSA-Express SNMP subagent support

6.6 LPAR mode z/VM guest

The OSA-Express Simple Network Management Protocol (SNMP) subagent (osasnmpd) supports management information bases (MIBs) for the OSA-Express features.

The subagent supports OSA-Express features as shown in the following tables:

Table 1. The qeth device driver support for OSA-Express features - Part 1: Mainframe CPCs as of z13
Feature	IBM® z16™	IBM z15®	z14 and z14 ZR1	z13® and z13s®
OSA-Express7S	Gigabit Ethernet 10 Gigabit Ethernet 25 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 25 Gigabit Ethernet 1000Base-T Ethernet	25 Gigabit Ethernet	Not supported
OSA-Express6S	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Not supported
OSA-Express5S	Not supported	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet
OSA-Express4S	Not supported	Not supported	1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet

Table 2. The qeth device driver support for OSA-Express features - Part 2: Earlier mainframe CPCs
Feature	zEC12 and zBC12	z196 and z114	System z10®
OSA-Express5S	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Not supported	Not supported
OSA-Express4S	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet	Not supported
OSA-Express3	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet
OSA-Express2	Not supported	Gigabit Ethernet 1000Base-T Ethernet	Gigabit Ethernet 10 Gigabit Ethernet 1000Base-T Ethernet

This subagent capability through the OSA-Express features is also called Direct SNMP to distinguish it from another method of accessing OSA SNMP data through OSA/SF, a package for monitoring and managing OSA features that does not run on Linux®.

See osasnmpd – Start OSA-Express SNMP subagent for information about the osasnmpd command itself.

To use the osasnmpd subagent, you need:

An OSA-Express feature that runs in QDIO mode with the latest textual MIB file for the appropriate LIC level (recommended)
The qeth device driver for OSA-Express (QDIO)
The osasnmpd subagent from s390-tools
net-snmp package 5.1.x or higher
