This page presents key information on the radio port. The radio
port is the radio port that communicates with the wireless network.
Settings
The Options section provides three check boxes for more details
on the port configuration and operating statistics. The basic page
without any options provides all information needed to monitor and
administer the port in normal operation. The options contain advanced
system troubleshooting that may be needed for performing comprehensive
site surveys.
Options
To display an option page, select the check box and click Apply.
- Detailed Configuration -- Displays
added configuration details such as Request to Send (RTS) and
data retry settings, firmware and boot block version levels, and
Regulatory domain code.
- Detailed Statistics -- Displays 20
more statistical fields covering packet fragments, collisions,
and other errors.
- Individual Rates -- Displays the data
transmission statistics at each of the individual rates.
Note The top section of the Radio Port page reports the
operational status, data rate, power, and identifying addresses
of the radio port.

Hardware page.
Status of "awc0"
The term "awc0" (Aironet Wireless Communications) is
part of Cisco Aironet's naming convention for this radio. This field
displays one of three possible operating states.
- Up -- The port is operating properly.
- Down -- The port is not operating.
- Error -- The port is in an error condition.
Maximum Rate (Mb/s)
Maximum rate of data transmission in megabits per second. Data
rates set to basic are followed by B.
IP Address
IP address of the radio port.
MAC Address
The Media Access Control (MAC) address is a unique identifier
assigned to the network interface by the manufacturer.
SSID
The Service Set Identifier (SSID) - also called the Radio SSID
- is a unique identifier that client devices use to associate with
the access point or a VLAN supported by the access point. The SSID
helps client devices distinguish between multiple wireless networks
and VLANs in the same vicinity and provides access to VLANs by wireless
client devices. Several access points on a network or sub-network
can share an SSID. You can configure up to 16 SSIDs on each radio
of an access point. An SSID can be any alphanumeric, case-sensitive
entry from 2 to 32 characters long.
Operational Rates
The data transmission rates supported and enabled by the device
for communication with client devices.
Transmit Power (mW)
The power level of radio transmission. The maximum setting is
government-regulated and must conform to established standards for
the country of operation. The setting can be reduced to conserve
power or reduce interference. Enter or change the power setting
by clicking Set Properties on the AP/Root
Radio Hardware page.
Statistics: Receive
This section reports the data traffic received through the AP/Root
Radio port.
- 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.
Statistics: Transmit
This section reports the data traffic transmitted from the AP/Root
Radio port.
- 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.
- Discarded Packets -- The number of
packets discarded by the device due to errors or network congestion.
- Forwarded Packets -- The number of
packets transmitted by the port that were acceptable or passable
through the filters.
- Max Retry Packets -- The number of
times request to send (RTS) reached the maximum retry number.
Click Set Properties to display
the AP/Root Radio Hardware page, where you can set the maximum
RTS value.
- Total Retries -- The total number
of retries that occurred through the radio port.
- Canceled Assoc. Lost -- Packets dropped
because a client device lost association with the device.
- Canceled AID -- Packets dropped by
a repeater because it roamed to a different parent during a retransmission
attempt.
- Lifetime Exceeded -- Fragmented packets
that were dropped because it took too long to deliver a fragment.
