SNMP Overview

StarlingX provides a containerized SNMP solution using Net-SNMP, supporting both SNMPv2c and SNMPv3.

StarlingX can generate SNMP traps for Alarm Events and Customer Log Events.

StarlingX also supports SNMP GETs and WALKs of an Active Alarm table and a historical Event (alarm SET/CLEAR and log) table.

SNMP functionality is integrated into StarlingX as an optionally configurable system application.

About SNMP Support

Support for Simple Network Management Protocol (SNMP) is implemented as follows:

• available using the controller’s node floating OAM IP address, over the standard SNMP UDP port 161, by default

• SNMPv2c and SNMPv3 are supported versions

• read-only access for all SNMP communities or all SNMPv3 users

• supported SNMP operations are GET, GETNEXT, GETBULK, SNMPv2C-TRAP2, SNMPv3-TRAP

  Note

  SNMPv3 INFORM, and SNMP SET operations are not supported.

• the SNMPv3 security levels that are supported are: NoAuthNoPriv, authNoPriv, authPriv

• support for MD5 for auth, and DES for priv, see http://www.net-snmp.org/

For information on enabling SNMP support, see Enabling SNMP Support.

SNMPv2-MIB (RFC 3418)

Support for the basic standard MIB for SNMP entities is limited to the System and SNMP groups, as follows:

• System Group: .iso.org.dod.internet.mgmt.mib-2.system

• SNMP Group: .iso.org.dod.internet.mgmt.mib-2.snmp

• coldStart and warmStart Traps

• support for Enterprise Registration and Alarm MIBs, see https://opendev.org/starlingx/snmp-armada-app/src/branch/master/stx-snmp-helm/docker/stx-snmp/mibs

Wind River Enterprise MIBs

Note

There are no product specific MIBs for wrsEnterpriseReg.mib and it will be supported in a future release.

StarlingX supports the Wind River Enterprise Registration and Alarm MIBs.

Enterprise Registration MIB, wrsEnterpriseReg.mib

Defines the Wind River Systems (WRS) hierarchy underneath the iso(1).org(3).dod(6).internet(1).private(4).enterprise(1). This hierarchy is administered as follows:

• .wrs(731), the IANA-registered enterprise code for Wind River Systems

• .wrs(731).wrsCommon(1).wrs<Module>(1-…), defined in wrsCommon<Module>.mib.

• .wrs(731).wrsProduct(2-…), defined in wrs<Product>.mib.

Alarm MIB, wrsAlarmMib.mib

Defines the common TRAP and ALARM MIBs for StarlingX products. The definition includes textual conventions, an active alarm table, a historical alarm table, a customer log table, and traps.

Textual Conventions

Semantic statements used to simplify definitions in the active alarm table and traps components of the MIB.
