Real-Time Troubleshooting

Real-Time Troubleshooting is designed to monitor and diagnose client-side issues as they occur in real-time. This functionality is supported on the following devices: AP3000, AP3000x, AP5010, and AP5050U/D.
Real-time client monitoring displays the following insights into client-side issues, allowing for prompt identification and resolution:
  • RSSI ( Received Signal Strength Indicator): Measures the power level that a device receives from an access point.
  • SNR (Signal-to-Noise Ratio): Indicates the quality of the signal relative to background noise.
  • Usage: Tracks the bandwidth consumption of connected devices.
  • Tx (Transmit) and Tx Retries: Monitors the number of packets sent and the number of retransmissions required.
  • Rx (Receive) and Rx Retries: Tracks the number of packets received and the number of retransmissions required.

Client Statistics displays the number of data packets transmitted and retried. Packet Stream displays the control packets used to manage the network.

You can run Real-Time Troubleshooting simultaneously on up to 10 access points. This capability is particularly useful for identifying and addressing roaming issues, where clients move between different access points.

By leveraging Real-Time Troubleshooting, network administrators can gain a comprehensive view of network performance and client behavior, enabling them to quickly address any issues that arise.

Use this task to begin Real-Time Troubleshooting.

  1. Navigate to Manage > Clients.
  2. Select an online client, and then select Real-Time Troubleshooting.
  3. Select a client from this site (Hostname of MAC).
  4. Select one or more APs to track the client, up to a maximum of 10.
  5. Select one of the following Packet Stream options view:
    • All
    • Data Frames
    • Management Frames
  6. Select Start.
    Note

    Note

    Starting up Real-Time Troubleshooting services typically takes about 10-20 seconds.
  7. Select Client Statistics to see the following detailed information about the transmission (Tx) and reception (Rx) of packets:
    • Tx Packets: The number of packets sent from the source device.
    • Rx Packets: The number of packets received by the destination device.
    • Tx Retries: The number of times packets had to be retransmitted due to errors or failures in the initial transmission.
    • Rx Retries: The number of times packets had to be re-received due to errors or failures in the initial reception.
    • Total Packets: The total number of packets sent and received.
    • Total Retries: The total number of retransmissions and re-receptions due to errors.
    • Total Data Usage: The overall amount of data transmitted and received, in bytes.
  8. Select Packet Stream to see the following details for each packet:
    • Time: The timestamp indicating when the packet was captured.
    • Serial Number: A unique identifier assigned to each packet for tracking purposes.
    • Source: The IP address or hostname of the device that sent the packet.
    • Destination: The IP address or hostname of the device intended to receive the packet
    • Protocol: The communication protocol used by the packet.
    • Length: The size of the packet in bytes.
  9. Select Stop to end Real-Time Troubleshooting.
