Description: Manages Nortel/Bay Networks Access Module (ACM) configuration and status for network device management.

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 ACMIB?

ACMIB is a vendor-specific MIB originally from Lucent Technologies (via its Access Concentrator product line, later associated with Nortel/Bay Networks branding) for managing remote-access concentrator sites that aggregate ATM and Ethernet connections. It exposes site-level configuration objects covering Ethernet IP addressing (siteEtherIpAddr, siteEtherIpMask), gateway configuration (siteGatewayAddr), ATM addressing (siteAtmAddrPrefix1, siteAtmAddrUser1), and a set of remote manager addresses (siteRemoteMgrAddr1-5) used for centralized management. This MIB is primarily configuration-oriented, letting an administrator verify a site's network identity and reachability settings (its assigned IP, ATM address, gateway, and which management stations can reach it) rather than exposing hardware sensors like temperature or CPU load directly, though ipThrottlingConfig suggests some traffic-control status as well. It sits under the broader Lucent enterprise MIB tree and depends on standard SNMP SMI conventions for structuring these objects. It was typically deployed on Lucent/Ascend-style Access Concentrator (ACM) units used by carriers and enterprises to aggregate remote-access/ATM traffic into a core network, where ACMIB SNMP monitoring lets administrators verify each site's addressing and management-reachability configuration.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACMIB. 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

  • Lucent/Nortel Access Concentrator (ACM)

Monitoring Examples

An administrator would poll siteName and siteID to identify a concentrator site, then check siteEtherIpAddr/siteEtherIpMask and siteGatewayAddr to confirm the unit's network configuration is correct, and verify siteRemoteMgrAddr1 through siteRemoteMgrAddr5 to ensure the expected management stations are authorized. A mismatch between the configured siteAtmAddrPrefix1/siteAtmAddrUser1 and the expected ATM address would reveal a misconfigured or unreachable site. The ipThrottlingConfig object would additionally show whether IP traffic throttling is active on the unit.

What Can Be Monitored

  • site network identity (name/ID)
  • Ethernet IP address/mask
  • gateway address
  • ATM address configuration
  • remote manager address list
  • IP throttling configuration
