Description: Manages Applied Innovation line card and chassis hardware for serial communication servers.

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 AISLC1-MIB?

AISLC1-MIB is the base MIB module for Applied Innovation's Series One Smart Line Cards (SLC), a family of line card hardware installed in AI chassis-based remote access and console server systems. Its sample objects (aiSystemOID, aiSLC1System) indicate it primarily defines the system identity object registration tree used to identify card type and firmware version rather than exposing rich runtime tables itself. As a system-identity MIB it supports hardware status monitoring indirectly, by letting management software determine exactly which SLC hardware/software variant is installed via its object identifier, which is a prerequisite for correctly interpreting counters and traps from companion MIBs on the same card. It is a foundational module that other AI SLC-family MIBs (such as AISLCASYNC-MIB and AISLCSYSCFG-MIB) build on for their object identity assignments. It is typically deployed in Applied Innovation chassis systems used for serial console access and remote terminal management in telecom central offices. Engineers can download the AISLC1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AISLC1-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.

Monitoring Examples

A management system would read the sysObjectID (populated from this MIB's aiSLC1System branch) to identify the installed line card as a Series One Smart Line Card and select the correct set of companion MIBs (e.g. AISLCASYNC-MIB) for further polling. Because this MIB largely defines identity OIDs rather than live counters, there is limited direct monitoring data beyond confirming card identity/version via the ai192/ai192Ver7 branches.

How to Use in IPNetwork Monitor

Example using aislc1StatFErrFifoInIsr OID:

Select an Applied Innovation Smart Line Card (SLC) network access equipment (legacy) 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 aislc1StatFErrFifoInIsr into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of RxFIFO half-full ISR interrupts which occurred. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

INT aislc1AdminLogsEnabled	1.3.6.1.4.1.539.11.1.1	INTEGER	read-write	Determines whether the SLC sends log messages to the console port of the AISwitch.
INT aislc1AdminTrapsEnabled	1.3.6.1.4.1.539.11.1.2	INTEGER	read-write	Determines whether the SLC sends SNMP Trap PDUs. If the active CLC in the AISwitch chassis with the SLC is not SNMP capable, this object cannot be set to the value on(1).
INT aislc1AdminTrapTimer	1.3.6.1.4.1.539.11.1.3	INTEGER	read-write	After a trap is generated, a timer is started. If the event that generated the trap occurs while the timer is running, no trap will be generated for the event. The value of this object is the duration of the timer in seconds.
STR aislc1OperLastMsgText	1.3.6.1.4.1.539.11.1.4	DisplayString	read-only	Contains the message text of the last log message that was sent by the SLC (or would have been sent, if log message transmission is disabled.
INT aislc1OperLastMsgNum	1.3.6.1.4.1.539.11.1.5	INTEGER	read-only	Contains the message number of the last log message that was sent by the SLC (or would have been sent, if log message transmission is disabled.
INT aislc1OperCrashCode	1.3.6.1.4.1.539.11.1.6	INTEGER	read-only	Contains a crash cause code. This object is for use as a varbind in TRAP PDUs only.
INT aislc1OperNumEventsSinceLastTrap	1.3.6.1.4.1.539.11.1.7	INTEGER	read-only	The number of times this trap was discarded because the aislcAdminTrapTimer had not yet expired since the last time the event which generated the trap occured. This object is for use as a varbind in TRAP PDUs only.
INT aislc1StatAIBfrsInUse	1.3.6.1.4.1.539.11.1.8	INTEGER	read-only	The number of AI buffers currently in use.
INT aislc1StatAIBfrsTotal	1.3.6.1.4.1.539.11.1.9	INTEGER	read-only	The total number of AI buffers.
INT aislc1StatActiveVCs	1.3.6.1.4.1.539.11.1.10	INTEGER	read-only	The number of Virtual Connections currently in some state other than Idle.
INT aislc1StatTotalVCs	1.3.6.1.4.1.539.11.1.11	INTEGER	read-only	The total number of Virtual Connection structures allocated on the SLC.
G32 aislc1StatMinLoopsPerSecond	1.3.6.1.4.1.539.11.1.12	Gauge32	read-only	The minimum number of iterations per second of the SLC's main polling loop during the sample period.
G32 aislc1StatAvgLoopsPerSecond	1.3.6.1.4.1.539.11.1.13	Gauge32	read-only	The average number of iterations per second of the SLC's main polling loop during the sample period.
G32 aislc1StatCurLoopsPerSecond	1.3.6.1.4.1.539.11.1.14	Gauge32	read-only	The number of iterations of the SLC's main polling loop during the past second.
C32 aislc1StatFErrFifoInIsrEx	1.3.6.1.4.1.539.11.1.15	Counter32	read-only	Number of RxFIFO half-full ISR interrupts which occurred. This is not always an error, but may be indicative of a heavy load on the X.25 software.
C32 aislc1StatErrFifoInFull	1.3.6.1.4.1.539.11.1.16	Counter32	read-only	Number of times the input FIFO was detected as full. This means that data has probably been lost, due to the inability of the X.25 software to keep pace with the RxFIFO.
C32 aislc1StatErrFifoInPort	1.3.6.1.4.1.539.11.1.17	Counter32	read-only	Number of times a bad port number has been received through the FIFO. This is probably indicative of a hardware failure, or perhaps a software problem in the CLC code.
C32 aislc1StatErrFifoInLost	1.3.6.1.4.1.539.11.1.18	Counter32	read-only	Number of characters received from the FIFO which were discarded because of lack of space.
C32 aislc1StatErrFifoOutFull	1.3.6.1.4.1.539.11.1.19	Counter32	read-only	Number of times the output FIFO was detected as full. This may be an indication of a hardware fault, or a breakdown in communications between the X.25 software and CLC regarding the status of a connection(i.e., if the CLC breaks a connection while the X.25 software is still using it, a TxFIFO full will definitely result).
C32 aislc1StatErrWinInCode	1.3.6.1.4.1.539.11.1.20	Counter32	read-only	Number of bad transaction codes received from the CLC via the window(i.e., the transaction code is out of range of the expected values).
C32 aislc1StatErrWinInPort	1.3.6.1.4.1.539.11.1.21	Counter32	read-only	Number of bad port numbers received from the CLC via the window(i.e., the relative port number is out of range of the expected values).
C32 aislc1StatErrWinInConn	1.3.6.1.4.1.539.11.1.22	Counter32	read-only	Number of bad connection transactions from the CLC via the window.
C32 aislc1StatErrWinInDisc	1.3.6.1.4.1.539.11.1.23	Counter32	read-only	Number of bad disconnection transactions from the CLC via the window. Note that this counter will probably be incremented if calls are disconnected following a link outage, it is not necessarily indicative of a serious problem.
C32 aislc1StatErrWinInAck	1.3.6.1.4.1.539.11.1.24	Counter32	read-only	Number of unexpected connection ACK's from the CLC via the window.

C32 aislc1StatErrWinOutLost	1.3.6.1.4.1.539.11.1.26	Counter32	read-only	Number of output window transactions which were lost due to buffer failures.
INT aislc1StatAIBfrsMax	1.3.6.1.4.1.539.11.1.27	INTEGER	read-only	The maximum number of AI buffers that have been used.
