Description: Manages ILMI (Integrated Local Management Interface) ATM signaling on the Ericsson AXD301 ATM switch.

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 AXD301-ILMI-MIB?

AXD301-ILMI-MIB manages ILMI (Integrated Local Management Interface) ATM signaling on the Ericsson AXD301 ATM switch, a carrier-grade ATM switching platform. Its data categories combine standard system-identity objects (sysDescr, sysObjectID, sysUpTime, sysContact, sysName, sysLocation, sysServices) with ATM Forum-defined per-port signaling objects (atmfPortTable) describing ATM port transmission types. It supports basic hardware/software status monitoring through the standard system group — sysUpTime for device uptime and sysDescr/sysObjectID for identifying the switch's software/hardware identity — while the ATM Forum objects report the operational transmission characteristics of individual ATM ports. It explicitly depends on the ATM Forum's ILMI/UNI MIB definitions (imported atmForum, atmForumAdmin, atmfTransmissionTypes) as well as the standard SNMPv2 System group (MIB-II). It is deployed in carrier and enterprise ATM backbone networks, where AXD301-ILMI-MIB SNMP monitoring supports the Ericsson AXD301 switch for ATM-based transport.

IPNetwork Monitor allows you to monitor SNMP objects defined in AXD301-ILMI-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

  • Ericsson AXD301 ATM switch

Monitoring Examples

An admin would poll sysUpTime to confirm the AXD301 switch has not unexpectedly rebooted, and sysDescr/sysObjectID to verify its software/hardware identity during an inventory audit. atmfPortTable/atmfPortEntry, keyed by atmfPortIndex, reports each ATM port's transmission type from atmfTransmissionTypes; a port reporting an unexpected or non-operational transmission type would reveal a physical-layer or signaling mismatch on that ATM interface.

What Can Be Monitored

  • system uptime
  • system identity (sysDescr/sysObjectID)
  • ATM port transmission type
  • ATM port index/status
