Avaya SBCE ipcsNetworkFailure on B1

Jeremy Boilard

Problem Statement

An Avaya Session Border Controller Enterprise (EMS + SBCE) reports a Minor alarm for maintenance object ipcsNetworkFailure. The alarm description is "Network failure alarm" and the equipment message indicates "RAISE:vmvoipsbce:CRITICAL:Link failure on interface B1."

Impact

Interface B1 is reporting a link failure. Depending on the deployment and traffic design, signaling or media traffic using that interface may be degraded, interrupted, or relying on alternate paths. The alarm may remain open in the monitoring dashboard until the interface link is restored or the condition is cleared.

Alarm

Maint Object: ipcsNetworkFailure; Description: Network failure alarm; Alarm Code: ACT; Equip No: RAISE:vmvoipsbce:CRITICAL:Link failure on interface B1

Troubleshooting Steps

  1. Confirm the alarm in the EMS or monitoring dashboard and verify that the affected maintenance object is ipcsNetworkFailure and the affected interface is B1.
  2. Check whether the alarm is still active or if it has cleared since initial detection.
  3. Review the SBCE network/interface status for interface B1 and confirm whether the link is administratively enabled and operationally up.
  4. If the SBCE is virtualized, verify that the virtual NIC mapped to interface B1 is connected, assigned to the correct port group or network, and shows link up at the hypervisor layer.
  5. If the SBCE uses a physical NIC or uplink, verify cabling, transceiver status, switch port status, VLAN assignment, and speed/duplex negotiation for the port connected to B1.
  6. Check for recent network, switch, hypervisor, or SBCE configuration changes that could have disconnected or remapped interface B1.
  7. Verify whether services or routes expected to use B1 are impacted, and confirm whether failover or alternate interfaces are carrying traffic as designed.
  8. After correcting the link condition, monitor the EMS/dashboard to confirm the ipcsNetworkFailure alarm clears.
  9. If the interface link appears healthy but the alarm remains active, collect current alarm details, interface status, and recent change information, then escalate to the appropriate Avaya SBCE support team or network operations team.

Resolution

No final technical resolution was documented in the sanitized ticket; the request was closed after being merged into another request. For this alarm, the expected remediation is to restore connectivity for SBCE interface B1 or correct the virtual/physical network mapping so that the interface reports link up, then confirm the ipcsNetworkFailure alarm clears in EMS or the monitoring dashboard.
