Objective

Radio statistics provide information about transmitted and received packets and byte counters on the radio interface of the access point (AP). This is useful when you face speed issues, congestion in the network, or connectivity problems. This information allows you to narrow down the problem that occurs in the network and to solve it.

This article helps you to view information about radio statistics on the WAP121 and WAP321 access points.

Applicable Devices

• WAP121

• WAP321

Software Version

• 1.0.3.4

Radio Statistics

Step 1. Log in to the Access Point Configuration Utility and choose Status and Statistics > Radio Statistics. The Radio Statistics page opens:

The following information is displayed under the Radio Statistics area:

• Packets Received — Number of packets that the AP received is shown.

• Bytes Received — Number of bytes that the AP received is shown.

• Packets Transmitted — Number of packets that the AP transmitted is shown.

• Bytes Transmitted — Number of bytes that the AP transmitted is shown.

• Packets Receive Dropped — Number of packets that the AP received and dropped because of overload is shown.

• Bytes Receive Dropped — Number of bytes that the AP received and were dropped is shown.

• Packets Transmit Dropped — Number of packets that the AP transmitted but were dropped is shown.

• Bytes Transmit Dropped — Number of bytes that the AP transmitted but were dropped is shown.

• Fragments Received — Number of fragments of frames that the AP received is shown.

• Fragments Transmitted — Number of fragments of frames that the AP transmitted is shown.

• Multicast Frames Received — Number of  multicast frames that the AP received is shown.

• Multicast Frames Transmitted — Number of  multicast frames that AP transmits is shown.

• Duplicate Frame Count — Number of times a frame with a sequence control field that indicates it is a duplicate is received.

• Failed Transmit Count — Number of times an MSDU frame was not transmitted as the transmit attempts could have either exceeded the short or long retry limits.

Note: MAC Service Data Unit (MSDU) is a type of frame aggregation that groups two or more data frames into a single large frame to increase throughput.

• Transmit Retry Count — The number of times the AP successfully transmits MSDU when a retry occurs.

• Multiple Retry Count — The number of times the AP successfully transmits MSDU after more than one retry.

• RTS Success Count — Number of CTS frames received by the AP in response to an RTS frame is shown.

Note: The source node which wants to send data frames initially sends request to send frames (RTS) if the size of the network packet is larger than the present threshold value, and the destination node acknowledges when it sends clear to send (CTS) frames.

• RTS Failure Count — Number of CTS frames that failed to be received in response to an RTS frame is shown.

• ACK Failure Count — Number of ACK frames that failed to be received is shown.

• FCS Error Count — Number of Frame check sequence (FCS) errors detected in the MPDU frame received is shown.

• Frames transmitted — Number of MSDU frames successfully transmitted is shown.

• WEP Undecryptable Count — Number of frames that are discarded because the AP could not decrypt them or because they were not encrypted.

Note: Wired Equivalent Privacy (WEP) is a security protocol that provides security when it encrypts the data transmitted from one end point to the other end point.
