Last Updated : Oct 30, 2026 |
Prolog information
Strict adherence to supported configurations is required to maintain eligibility for Avaya support. Any deviation from these guidelines should be treated as a controlled change.

Support guidelines

  • Only the VLAN configuration procedures outlined in this document are validated by Avaya.
  • Use of system tools such as nmcli is permitted only as outlined in this document. Any other tools, commands, or procedures not documented here are, by default, considered unsupported.
  • Changes to OOBM, bridge0, or existing bonded interfaces via Cockpit are not supported if those components were originally configured using the script.

Change control requirements

  • Submit a request to Avaya support before applying custom VLAN or bond configurations outside the documented models
  • Maintain configuration backups and change logs before applying VLAN changes
  • If unsupported configurations are applied and connectivity is lost, a full re-image of the host may be required
Note:
To confirm whether a specific VLAN topology is supported, customers are advised to contact Avaya technical support prior to implementation.
