What Is AISLCASYNC-MIB?

AISLCASYNC-MIB is a proprietary Applied Innovation MIB for managing asynchronous serial links on Smart Line Card (SLC) modules, covering per-link application assignment, connection options, and call state. It exposes tables describing each async link's configured application, direct-connect alias, flow-control (Xon) interval, and active call/session state, as well as a separate connection-options table for DSR-based behaviors. For hardware/software status monitoring it primarily lets an administrator confirm whether each serial link is idle, connected, or in a call, and whether latency-minimizing and flow-control options are applied as expected, which helps detect a hung or misconfigured async port. It is a companion module to AISLC1-MIB (hardware identity) and AISLCSYSCFG-MIB (system-wide config), sharing the same "ai" enterprise tree rather than any IETF standard. It is typically deployed on Applied Innovation Smart Line Cards providing async terminal/modem access, making AISLCASYNC-MIB SNMP monitoring a routine part of telecom remote access and console-server deployments.

IPNetwork Monitor allows you to monitor SNMP objects defined in AISLCASYNC-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

An operator would walk aiSLCAsyncTable/aiSLCAsyncEntry indexed by aislcasyLinkNumber to check aislcasyCallState for each async port, revealing which serial links are currently active versus idle, and inspect aislcasyApplication and aislcasyDirectConnectAlias to confirm the correct application is bound to a link. A link stuck in an unexpected aislcasyCallState, or aiSLCAsyncConnOptTable showing aislcacoOnActiveDSR misconfigured, would indicate a stalled or misconfigured serial session.
