In Avaya Aura Communication Manager (CM), how can you verify which COS Group a user belongs to?

Question

Options

• Aby checking the Tennant Group that they belong to
• Bby using the status station command
• Cby using the list usage extension command
• Dby listing the COS Groups in System Manager

• B
  6% (1)
• C
  94% (17)

Explanation

Option C is correct because the list usage extension command in Avaya CM displays all configuration records associated with an extension, including its Class of Service (COS) Group assignment, giving you a direct lookup of where that extension is referenced within the system's feature configurations.

Why the distractors are wrong:

• A (Tenant Group): Tenant Groups control dial plan partitioning in multi-tenant environments - they are a separate construct from COS Groups and do not reveal a user's COS assignment.
• B (status station): The status station command reports real-time operational state (registered, idle, in-use), not configuration data like COS Group membership.
• D (list COS Groups in System Manager): System Manager provides a high-level administrative view, but browsing COS Groups there does not efficiently show which individual user belongs to a specific group - you'd be searching from the wrong direction.

Memory tip: Think of list usage as "who uses what" - it maps an extension to everything it's tied to in CM configuration, including its COS Group. If you need to know what a station is configured with, list usage extension is your lookup command.
