Description: Monitors SIAE MICROELETTRONICA microwave radio adaptive code modulation performance statistics.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SIAE-ACM-STATISTICS-MIB?

SIAE-ACM-STATISTICS-MIB is a SIAE Microelettronica proprietary MIB reporting ACM (Adaptive Code Modulation, a technique that dynamically adjusts modulation to maintain a microwave link under fading conditions) performance statistics. Its objects cover a MIB version, a transport-path (TP) link table (policy ID, start/stop control, label, row status), a TP-profile table (15-minute/24-hour alarm enables and thresholds), a maintenance table (counter/alarm clear actions), and an interval table (ID, type, status). As a performance/configuration MIB it lets an administrator confirm ACM alarm thresholds are tuned to catch a link that has fallen back to a lower, less-efficient modulation under fading. It is deployed on SIAE Microelettronica microwave transmission equipment using Adaptive Code Modulation. Engineers can download the SIAE-ACM-STATISTICS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SIAE-ACM-STATISTICS-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

SIAE Microelettronica microwave transmission equipment (ACM)

Monitoring Examples

An administrator checks acmsTpProfile15mThreshold to confirm ACM alarm sensitivity is tuned appropriately before troubleshooting a microwave link falling back to lower modulation during a fade event.

How to Use in IPNetwork Monitor

Example using acmsProfileCounterValue OID:

Select an SIAE Microelettronica microwave transmission equipment, ACM (Adaptive Code Modulation alarm thresholds) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type acmsProfileCounterValue into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the when index acmsTpProfileId is downshift, this object counts the number of times that the active profile is moved to a lower one. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
acmStats	1.3.6.1.4.1.3373.1103.75			Adaptive Code Modulation (ACM) Statistics (Performance Monitoring)
INT acmsMibVersion	1.3.6.1.4.1.3373.1103.75.1	INTEGER	read-only	Numerical version of this module. The string version of this MIB have the following format: XX.YY.ZZ so, for example, the value 1 should be interpreted as 00.00.01 and the value 10001 should be interpreted as 01.00.01.
acmsTpLinkTable	1.3.6.1.4.1.3373.1103.75.2		not-accessible	Table with ACM Termination Point of the radio links. This table contains object to activate and deactivate the buildup of counters.
acmsTpLinkRecord	1.3.6.1.4.1.3373.1103.75.2.1		not-accessible	Entry of acmsTpLinkTable.
I32 acmsTpLinkId	1.3.6.1.4.1.3373.1103.75.2.1.1	Integer32	not-accessible	This object identifies the Radio link.
I32 acmsTpLinkPolId	1.3.6.1.4.1.3373.1103.75.2.1.2	Integer32	not-accessible	This object identifies the Radio link polarization for XPIC configuration. In non XPIC link this object should be 1.
INT acmsTpLinkStartStop	1.3.6.1.4.1.3373.1103.75.2.1.3	INTEGER	read-create	This object is used to start and to stop the statistic (Perfomance Monitoring) counter evaluation.
STR acmsTpLinkLabel	1.3.6.1.4.1.3373.1103.75.2.1.4	DisplayString	read-only	ASCII string used to identify the ACM Termination Point.
ROW acmsTpLinkRowStatus	1.3.6.1.4.1.3373.1103.75.2.1.5	RowStatus	read-create	Status of this row of acmsTpLinkTable. When set to notInService, associated acmsTpProfileTable rows may be added, deleted and modified. When an attempt is made to set acmsTpLinkRowStatus to active, there is at least a row in acmsTpProfileTable with first index equal to acmsTpLinkId. Otherwise, the error inconsistentValue is returned to the set attempt. The creation of a row in this table, creates a row with the same index in of acmsTpMaintTable. The deletion of a row in this table, deletes a row with the same index in of acmsTpMaintTable. If this object is set to destroy, must not be no rows in acmsTpProfileTable associated by acmsTpLinkId to the row that is being deleted, otherwise, the error inconsistentValue is returned to the set attempt. Hence, profile instances must be deleted before this link instance.
acmsTpProfileTable	1.3.6.1.4.1.3373.1103.75.3		not-accessible	ACM Termination Point Thresholds Class table. Table with AcmsTpProfileRecord records. This table contains alarms and related thresholds to notify them within a specific time interval.
acmsTpProfileRecord	1.3.6.1.4.1.3373.1103.75.3.1		not-accessible	Entry of acmsTpLinkTable. Several instances (a instance for each ACM profile supported by the radio system) of this record is created on creation of acmsTpLinkTable.
ACM acmsTpProfileId	1.3.6.1.4.1.3373.1103.75.3.1.1	AcmProfile	not-accessible	This object identifies the ACM profile of the radio system.
ALA acmsTpProfile15mAlarm	1.3.6.1.4.1.3373.1103.75.3.1.2	AlarmStatus	read-only	If acmsCounteValue crosses the threshold acmsTpProfile15mThreshold, this alarm is notified.
ALA acmsTpProfile24hAlarm	1.3.6.1.4.1.3373.1103.75.3.1.3	AlarmStatus	read-only	If acmsCounteValue crosses the threshold acmsTpProfile24hThreshold, this alarm is notified.

For downshift and upshift profiles, this threshold reports the number of times a profile must be changed within a 15 minutes interval to set acmsTpProfile15mAlarm.
I32 acmsTpProfile24hThreshold	1.3.6.1.4.1.3373.1103.75.3.1.5	Integer32	read-create	Number of seconds within a 24 hours interval to set acmsTpProfile24hAlarm. The special value 0 turn off the alarm. For the profiles downshift and upshift, this threshold reports the number of times a profile must be changed within a 24 hours interval to set acmsTpProfile24hAlarm.
ROW acmsTpProfileRowStatus	1.3.6.1.4.1.3373.1103.75.3.1.6	RowStatus	read-create	Status of this row of acmsTpProfileTable. A row in the acmsTpProfileTable may not be created, deleted, set to notInService or otherwise modified if the there is no a row in acmsTpProfileTable with the same acmsTpLinkId and the associated acmsTpLinkRowStatus object is equal to active. However, if the acmsTpLinkRowStatus object is equal to notInService, a row may be created, deleted or modified. In other words, a profile may not be added, deleted or modified if the ACM statistics of a radio link is active. The creation on a row in this table, creates a row with the same index in of acmsProfileCounterTable. If this object is set to destroy, the associated instance of acmsProfileCounterTable will also be deleted by this action.
acmsTpMaintTable	1.3.6.1.4.1.3373.1103.75.4		not-accessible	Table with Command for maintenance of Termination Point. Objects in this table is not persistent.

(19) a day interval N. 16 (The oldest day counters - 4 hours ago). The interval identified by 4 is the most recently completed 15 minute interval, and the interval identified by N is the interval immediately preceding the one identified by N-1.
INT acmsIntervalType	1.3.6.1.4.1.3373.1103.75.5.1.2	INTEGER	read-only	The type of the counter interval: it can describe a daily block counter or a counter related to a 15 minutes interval.

When index acmsTpProfileId is upshift, this object counts the number of times that the active profile is moved to an upper one. When index acmsTpProfileId is unavailable, this object counts the number of seconds in which the modem is not locked. For all other values of acmsTpProfileId the object counts the number of seconds for which the rx profile relative to this row of the table has been active.
