Aruba switch optical port

Optical access and telecom site reference Published 03 Nov 2025

Use this reference to prepare product questions for CGWEB NETWORKS. Check interfaces, capacity, protection and installation requirements against the current product documentation.

You can view optical port configuration on an Aruba switch using CLI commands like show interfaces or show tech receivers, or via the switch dashboard in the WebUI.

Using CLI Commands

Check Port Status and ConfigurationRun show interfaces to display detailed information about a specific port, including transceiver type, link status, speed, duplex, VLAN, and traffic statistics. A status of UP indicates normal operation, while DOWN may indicate a disconnected or misconfigured port. Use show interfaces brief to get a summary of all ports, including their admin state, link state, and speed.

View Transceiver Details

Use show tech receivers to display information about installed optical transceivers, including real-time TX/RX optical power, temperature, and coding compatibility. This is useful for troubleshooting optical links or verifying that SFP/SFP+ modules are functioning correctly.

Check Mode and Duplex

The port's speed and duplex settings can be verified with show interfaces brief. Ensure that the port mode matches the connected device to avoid mismatches that can cause errors. Using the WebUI DashboardAccess the Ports TabNavigate to Manage > Devices > Switches, select the switch, then go to Interface > Ports.

The Ports page displays each port's number, name, type, status, speed, VLAN, LAG membership, and admin state.

Drill Down for Port-

Level Details

Click on a specific port to view detailed information, including traffic statistics, frame counters, and optical transceiver parameters if applicable. You can also filter ports by groups, labels, or sites to quickly locate the optical ports of interest.

Best Practices

Verify that the transceiver type matches the switch port and the connected device. Monitor TX/RX optical power to ensure signal quality.

Use the CL

I for quick troubleshooting and the WebUI for visual monitoring and historical traffic analysis. Check for speed/duplex mismatches if the link is unstable or not coming up. By combining CLI commands and the WebUI dashboard, you can effectively monitor, verify, and troubleshoot optical port configurations on Aruba switches.
