Using Diagnostic Pages
• SSID—The unique identifier that client devices use to associate with the access point radio. The
SSID helps client devices distinguish between multiple wireless networks in the same vicinity.
• Operational Rates—The data transmission rates supported and enabled by the access point for
communication with client devices.
• Transmit Power (mW)—The power level of radio transmission. You can reduce the transmit power
to conserve power or reduce interference. Click Set Properties to display the AP Radio Hardware
page, where you can change this setting.
Receive Statistics
• Unicast Packets—The number of packets received in point-to-point communication.
• Multicast Packets—The number of packets received that were sent as a transmission to a set of
nodes.
• Total Bytes—The total number of bytes received.
• Total Errors—The total number of packets determined to be in error.
• Discarded Packets—Packets discarded due to errors or network congestion.
• Forwardable Packets—Packets received by the port that were acceptable or passable through the
filters.
• Filtered Packets—Packets that were stopped or screened by the filters set up on the port.
• Packet CRC Errors—Cyclic redundancy check (CRC) errors that were detected in a received packet.
• Packet WEP Errors—Encryption errors received through this port.
• Overrun Packets—Packets that were discarded because the access point had a temporary overload
of packets to handle.
• Duplicate Packets—Packets that were received twice because an acknowledgment was lost and the
sender retransmitted the packet.
• Lifetime Exceeded—Fragmented packets that were dropped because it took too long to get the next
fragment.
• MIC Packets—Total number of packets received over this radio since system startup and for which
a MIC has been requested to be validated with the MMH algorithm.
• MIC Errors—Total number of packets received over this radio since system startup that failed MIC
validation with the MMH algorithm.
• MIC Sequ. Errors—Total number of packets received over this radio since system startup that failed
MIC validation with the MMH algorithm specifically due to sequence number and duplicate packet
errors.
• MIC Auth. Errors—Total number of packets received over this radio since system startup that failed
MIC validation with the MMH algorithm specifically due to cryptographic key-mismatch errors.
Transmit Statistics
• Unicast Packets—The number of packets transmitted in point-to-point communication.
• Multicast Packets—The number of packets transmitted that were sent as a transmission to a set of
nodes.
• Total Bytes—The number of bytes transmitted from the port.
• Total Errors—The number of packets determined to be in error.
