Supported MIBs

The device contains an embedded SNMP agent supporting the MIBs listed below. A description in HTML format for all supported MIBs can be found in the MIBs directory in the release package.

■

Standard MIB (MIB-2): The various SNMP values in the standard MIB are defined in RFC 1213. The standard MIB includes various objects to measure and monitor IP activity, TCP activity, UDP activity, IP routes, TCP connections, interfaces, IPv4 address to physical address mapping (ipNetToMediaTable), and general system description.

●

The standard icmpStatsTable and icmpMsgStatsTable under MIB-2 support ICMP statistics for both IPv4 and IPv6.

●

The inetCidrRouteTable (from the standard IP-FORWARD-MIB) supports both IPv4 and IPv6.

■

System MIB (under MIB-2): Standard system group: sysDescr, sysObjectID, sysUpTime, sysContact, sysName, sysLocation, and sysServices. You can replace the value of sysObjectID.0 with a variable value using the ini file parameter [SNMPEnterpriseOID]. This parameter is polled during startup and overwrites the standard sysObjectID. SNMPSysName is an administratively assigned name for this managed node. By convention, this is the node's fully-qualified domain name (FQDN). If the name is unknown, the value is the zero-length string.  If the [HostName] ini file parameter is configured, its value overwrites the value of SNMPSysName.

■

Host Resources MIB (RFC 2790): The Host Resources MIB is used for managing host systems. The term host is any computer that communicates with other similar computers connected to the Internet and that is directly used by one or more human beings. The following are the Host Resources MIB objects:

●

hrSystem group

●

hrStorage group (basic only)

●

hrDevice group (CPU, RAM, Flash - basic only)

●

hrSWRunPerf (basic only)

●

hrSWInstalled (OS only)

■

RTP MIB: The MIB is supported according to RFC 2959. It contains objects relevant to the RTP streams generated and terminated by the device and to the RTCP information related to these streams.

■

Notification Log MIB: Standard MIB (RFC 3014 - iso.org.dod.internet.mgmt.mib-2) supported for implementation of Carrier Grade Alarms.

■

SNMP Usm MIB: (RFC 3414) Implements the user-based Security Model.

■

SNMP Vacm MIB: (RFC 3415) Implements the view-based Access Control Model.

■

■

ipForward MIB: (RFC 2096) Fully supported.

■

RTCP-XR: (RFC) implements the following partial support:

●

The rtcpXrCallQualityTable is fully supported.

In the rtcpXrHistoryTable, support of the RCQ objects is provided only with no more than 3 intervals, 15 minutes long each.

●

Supports the rtcpXrVoipThresholdViolation trap.

■

ds1 MIB: supports the following:

●

dsx1ConfigTable: partially supports the following objects with SET and GET applied:

◆

dsx1LineCoding

◆

dsx1LoopbackConfig

◆

dsx1LineStatusChangeTrapEnable

◆

dsx1CircuitIdentifier

All other objects in this table support GET only.

●

dsx1CurrentTable

●

dsx1IntervalTable

●

dsx1TotalTable

●

dsx1LineStatusChange trap

■

SONET MIB: (RFC 3592) implements the following partial support:

●

In the SonetMediumTable, the following objects are supported:

◆

SonetMediumType

◆

SonetMediumLineCoding

◆

SonetMediumLineType

◆

SonetMediumCircuitIdentifier

◆

sonetMediumLoopbackConfig

●

In the SonetSectionCurrentTable, the following objects are supported:

◆

lsonetSectionCurrentStatus

◆

sonetSectionCurrentESs

◆

sonetSectionCurrentSESs

◆

sonetSectionCurrentSEFSs

◆

sonetSectionCurrentCVs

●

In the SonetLineCurrentTable, the following objects are supported:

◆

sonetLineCurrentStatus

◆

sonetLineCurrentESs

◆

sonetLineCurrentSESs

◆

sonetLineCurrentCVs

◆

sonetLineCurrentUASs

●

sonetSectionIntervalTable

●

sonetLineIntervalTable

●

sonetPathCurrentTable

●

sonetPathIntervalTable

■

acPSTN MIB:

●

acSonetSDHTable: currently has one entry (acSonetSDHFbrGrpMappingType) for selecting a low path mapping type. Relevant only for PSTN applications. (Refer to the MIB for more details.)

■

acSystem MIB:

●

acSysTransmissionType: sets the transmission type to optical or DS3 (T3).

In addition to the standard MIBs, the complete product series contains proprietary MIBs:

■

AC-TYPES MIB: lists the known types defined by the complete product series. This is referred to by the sysObjectID object in the MIB-II.

■

AcBoard MIB: includes the acTrap group.

Each proprietary MIB contains a Configuration subtree for configuring the related parameters. In some, there also are Status and Action subtrees.

■

AcAnalog MIB

■

acControl MIB

■

acMedia MIB

■

acSystem MIB

■

acSysInterfaceStatusTable: supports the networking multiple interfaces feature status. This table reflects all the device's active interfaces. The lines indices consist of both the Entry Index and the Type Index. The table contains the following columns:

●

Entry Index - related Interface index in the interface configuration table (if the table is empty,i.e., there is only single IP address, the index appears with 0)

●

Type Index - 1 for IP Address and 2 for IPv6 Link-Local Address

●

Application Types - type assigned to the interface

●

Status Mode - interface configuration mode

●

IP Address - IP address (either IPv4 or IPv6) for this interface

●

Prefix Length - number of ‘1’ bits in this interface’s net mask

●

Gateway - default gateway

●

Vlan ID - VLAN ID of this interface

●

Name - interface’s name

●

Primary DNS Server IP Address - IP address of primary DNS server for this interface

●

Secondary DNS Server IP Address - IP address of secondary DNS server for this interface

■

acSysModuleTable

■

acIPMediaChannelsresourcesTable: IPMedia channels information such as Module ID and DSP Channels Reserved

■

acPSTN MIB

■

acGateway MIB: This proprietary MIB contains objects related to configuration of the SIP device. This MIB complements the other proprietary MIBs. The acGateway MIB includes the following groups:

●

Common: parameters common to both SIP and H.323.

●

SIP: SIP only parameters.

■

AcAlarm: This is a proprietary carrier-grade alarm MIB. It is a simpler implementation of the notificationLogMIB and the IETF suggested alarmMIB (both supported).

The acAlarm MIB has the following groups:

●

ActiveAlarm: straight forward (single indexed) table listing all currently active Alarms together with their bindings (the Alarm bindings are defined in acAlarm. acAlarmVarbinds and also in acBoard.acTrap. acBoardTrapDefinitions. oid_1_3_6_1_4_1_5003_9_10_1_21_2_0).

●

acAlarmHistory: straight forward (single indexed) table listing all recently sent Alarms together with their bindings (the Alarm bindings are defined in acAlarm. acAlarmVarbinds and also in acBoard.acTrap. acBoardTrapDefinitions. oid_1_3_6_1_4_1_5003_9_10_1_21_2_0).

The table size can be altered by one of the following:

●

notificationLogMIB.notificationLogMIBObjects.nlmConfig.nlmConfigGlobalEntryLimit

●

notificationLogMIB.notificationLogMIBObjects.nlmConfig.nlmConfigLogTable.nlmConfigLogEntry.nlmConfigLogEntryLimit.

The table size (i.e., number of contained alarms) can be any value between 10 and 1,000 (default is 500)100 (default is 100)
