To check the High Availability (HA) status in an Aruba Mobility Controller, you can use the CLI (Command Line Interface) or the Web UI. Here’s how you can do it:

---

🔧 Using CLI (SSH or Console):

1. Login to the controller via SSH or console.
2. Run the following command:

show ha

This will display the HA configuration and status including:

• Role (Active/Standby)
• HA state (UP/DOWN)
• Synchronization status
• Heartbeat info
• Peer IP and state

💡 Additional Useful CLI Commands:

Command Description show ha Shows general HA status show ha group-membership Shows the group membership of controllers in HA setup show switchinfo Shows controller role (master, standby, etc.) show redundancy Displays detailed HA redundancy state show log system 50 Check system logs for HA-related events

🌐 Using Web UI:

1. Log in to the Aruba Controller Web UI.
2. Go to Configuration > Redundancy or Dashboard > System > Redundancy (depending on firmware).
3. You’ll see the controller role, peer info, and synchronization status.

📝 Tips:

• Active controller handles client traffic.
• Standby controller takes over if the active one fails.
• Ensure both controllers are synchronized and licenses are shared if using license pooling.
