What Is BAY-STACK-ADAC-MIB?

BAY-STACK-ADAC-MIB is an Avaya (formerly Nortel) proprietary MIB implementing Automatic Device Attachment Configuration (ADAC), a feature on Avaya/Nortel Ethernet Routing Switch (ERS) and BayStack switches that auto-detects and configures ports connecting to Avaya IP telephones. It exposes configuration-oriented data such as administrative enable state, operating mode, call-server and uplink port designations, and voice VLAN assignment, along with notification controls for reporting ADAC events. While primarily a configuration module, it supports operational monitoring of phone auto-provisioning status through objects like bsAdacOperEnable and lists of active call-server/uplink ports, and it can raise SNMP notifications (bsAdacNotifications) when phone attachment events occur. It is closely tied to the switch's underlying VLAN and port management MIBs since it references voice VLAN and physical port lists directly. Typical deployment is in Avaya Unified Communications environments where IP phones are plugged into edge switch ports and need automatic VLAN tagging and QoS configuration without manual per-port setup. Engineers can download the BAY-STACK-ADAC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BAY-STACK-ADAC-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

  • Avaya/Nortel BayStack switch
  • Avaya Ethernet Routing Switch (ERS)

Monitoring Examples

An administrator would check bsAdacAdminEnable and bsAdacOperEnable to confirm ADAC is active on a switch, then inspect bsAdacUplinkPortList and bsAdacCallServerPortList to verify which ports have been auto-identified as uplinks versus phone-facing ports. If a newly connected IP phone fails to get voice VLAN tagging, comparing bsAdacVoiceVlan against the port's actual VLAN membership and reviewing bsAdacNotifications would reveal whether ADAC failed to detect the device correctly.

What Can Be Monitored

  • ADAC admin/operational enable state
  • operating mode
  • call server port assignment
  • uplink port assignment
  • voice VLAN configuration
  • ADAC notification events
