Querying the Oracle VM Server for SPARC MIB

When a system has large number of domains, the Oracle Solaris SNMP agent (net-SNMP) might time out before being able to respond to an SNMP request. To increase the timeout value, use the –t option to specify a longer timeout value. For example, the following snmpwalk command sets the timeout value to 20 seconds:

# snmpwalk -t 20 -v1 -c public localhost SUN-LDOM-MIB::ldomTable

You can also use the –t option to specify the timeout value for the snmpget and snmptable commands.

• To retrieve a single MIB object:

  # snmpget -v version -c community-string host MIB-object

• To retrieve an array of MIB objects:

  Use the snmpwalk or snmptable command.

  # snmpwalk -v version -c community-string host MIB-object
  # snmptable -v version -c community-string host MIB-object

Example 1  Retrieving a Single Oracle VM Server for SPARC MIB Object (snmpget)

The following snmpget command queries the value of the ldomVersionMajor object. The command specifies snmpv1 (–v1) and a community string (–c public) for the localhost host.

# snmpget -v1 -c public localhost SUN-LDOM-MIB::ldomVersionMajor.0
SUN-LDOM-MIB::ldomVersionMajor.0 = INTEGER: 1

Example 2  Retrieving Object Values From ldomTable (snmpwalk)

The following examples show how to use the snmpwalk command to retrieve object values from ldomTable.

• The following snmpwalk -v1 command returns the values for all objects in the ldomTable table.

  # snmpwalk -v1 -c public localhost SUN-LDOM-MIB::ldomTable
  SUN-LDOM-MIB::ldomName.1 = STRING: primary
  SUN-LDOM-MIB::ldomName.2 = STRING: LdomMibTest_1

  SUN-LDOM-MIB::ldomAdminState.2 = INTEGER: 0

  SUN-LDOM-MIB::ldomOperState.2 = INTEGER: bound(6)

  SUN-LDOM-MIB::ldomMemUnit.2 = INTEGER: megabytes(2)

  SUN-LDOM-MIB::ldomNumCrypto.2 = INTEGER: 0
  SUN-LDOM-MIB::ldomNumIOBus.1 = INTEGER: 2
  SUN-LDOM-MIB::ldomNumIOBus.2 = INTEGER: 0
  SUN-LDOM-MIB::ldomUUID.1 = STRING: 5f8817d4-5d2e-6f7d-c4af-91b5b34b5723

  SUN-LDOM-MIB::ldomMacAddress.1 = STRING: 00:14:4f:46:47:d6
  SUN-LDOM-MIB::ldomMacAddress.2 = STRING: 00:14:4f:f8:d5:6c
  SUN-LDOM-MIB::ldomHostID.1 = STRING: 0x844647d6
  SUN-LDOM-MIB::ldomHostID.2 = STRING: 0x84f8d56c
  SUN-LDOM-MIB::ldomFailurePolicy.1 = STRING: ignore
  SUN-LDOM-MIB::ldomFailurePolicy.2 = STRING: ignore
  SUN-LDOM-MIB::ldomMaster.1 = STRING:
  SUN-LDOM-MIB::ldomMaster.2 = STRING:
  SUN-LDOM-MIB::ldomExtMapinSpace.1 = STRING: off
  SUN-LDOM-MIB::ldomExtMapinSpace.2 = STRING: off

  SUN-LDOM-MIB::ldomShutdownGroup.2 = INTEGER: 15
  SUN-LDOM-MIB::ldomPerfCounters.1 = STRING: htstrand
  SUN-LDOM-MIB::ldomPerfCounters.2 = STRING: global,htstrand
  SUN-LDOM-MIB::ldomNumCMI.1 = INTEGER: 0
  SUN-LDOM-MIB::ldomNumCMI.2 = INTEGER: 0
  SUN-LDOM-MIB::ldomBootPolicy.1 = STRING: n/a
  SUN-LDOM-MIB::ldomBootPolicy.2 = STRING: warning

• The following snmpwalk commands use snmpv2c and snmpv3 to retrieve the contents of ldomTable:

  # snmpwalk -v2c -c public localhost SUN-LDOM-MIB::ldomTable
  # snmpwalk -v 3 -u test -l authNoPriv -a MD5 -A testpassword localhost \
  SUN-LDOMMIB::ldomTable

Example 3  Retrieving Object Values From ldomTable in Tabular Form (snmptable)

The following examples show how to use the snmptable command to retrieve object values from ldomTable in tabular form.

• The following snmptable -v1 command shows the contents of ldomTable in tabular form.

  # snmptable -v1 -c public localhost SUN-LDOM-MIB::ldomTable

• The following snmptable command shows the contents of ldomTable in tabular form by using snmpv2c.

  Note that for the v2c or v3 snmptable command, use the –CB option to specify only GETNEXT, not GETBULK, requests to retrieve data.

  # snmptable -v2c -CB -c public localhost SUN-LDOM-MIB::ldomTable
