Configuring a Wireless Modem Card Following is an example of the running configuration for the “master” end of a 6-MHz high-throughput link with a single antenna. In these examples, UBR1 and UBR2 refer to the two Cisco uBR7200 series routers used at the ends of the radio link. The wireless modem cards are assumed to be in slot 6 of each of the routers. The reference to radio 6/0 indicates that this interface occupies slot 6 and port 0.
Configuring a Wireless Modem Card If you are using two antennas and problems occur with the dual antenna command, reissue the command specifying loopback local if main or loopback local if diversity to help isolate the problem. It may also be helpful to run a power-on self test (POST). The POST can be configured to run either once or every time the link is initiated. The following commands configure a self-test to run when the first no shut command is entered.
Configuring a Wireless Modem Card RF-to-RF Link Example uBR1 (master) IP address 10.0.0.1 Transmit at 5.733 GHz Receive at 5.781 GHz uBR2 (slave) IP address 10.0.0.2 Receive at 5.733 GHz Transmit at 5.781 GHz 28547 Figure 30 The configurations for both ends of the link are shown below. uBR1 Configuration: UBR1# show running-configuration interface radio 6/0 Current configuration: ! interface radio6/0 ip address 10.0.0.1 255.255.255.0 radio master radio receive-antennas 1 radio operating-band tx 5733.
Configuring a Wireless Modem Card Caution If the maximum cable loss parameters are used with short cables, the transmit signal from the wireless modem card to the transverter can be too strong, resulting in damage to the transverter. As the cable length increases, the cable loss increases.
Command Reference To confirm that the link has been established, send a ping command to the other end of the link, using the following commands: UBR1(config-if)# exit UBR1(config)# exit UBR1# ping 10.0.0.2 UBR2(config-if)# exit UBR2(config)# exit UBR2# ping 10.0.0.1 If the link is not established, double-inspect the duplexer and the cabling to the antenna itself. Check that the duplexers are installed with the correct orientation. It also might be necessary to adjust the transmit-power.
Command Reference • Operating Commands—Used during normal operation to configure baseline encryption, duplexer characteristics, LEDs, and Automatic Response Query (ARQ) settings: – radio privacy – radio duplexor – radio led – radio arq – show interfaces radio (arq) • Monitoring the System—Used during operation to monitor the system’s actions and set measurements of system statistics: – radio metrics-threshold – radio threshold – show interfaces radio (thresholds) – show interfaces radio (link-metrics) –
Command Reference Syntax Conventions The commands used in this section follow the conventions in Table 7. Table 7 Syntax Conventions Convention Meaning Comments Boldface Commands and keywords you enter literally as shown transmit-power Italics Variables for which you supply command type interface values You replace the variable with the type of interface. Square brackets ([ ]) Optional elements command [abc] abc is optional (not required), but you can choose it.
Command Reference Startup Commands Use these commands to determine the status of the current configuration, and to activate and deactivate the link: • show interfaces radio—To display the protocol-specific details supported • show running-configuration—To display the configuration currently in effect on the Cisco uBR7200 series router • show startup-configuration—To display the system startup configuration • shut, no shut—To shut down and reinstate the link • write—To write the configuration curre
Command Reference show running-configuration show startup-configuration Use the show running-configuration command in privileged EXEC mode to display the configuration currently in effect on the Cisco uBR7200 series router. Use the show startup-configuration command in privileged EXEC mode to display the system startup configuration.
Command Reference shut (shutdown and restart) Use this command in interface configuration mode to shut down the radio link. Use the no version of the command to reinstate the radio link. The state of the link is displayed on the console. Caution When using telnet to control the far end of the link, use the clear interface radio slot/port command in privileged EXEC mode in place of the shut/no shut command. The clear interface command will cause an automatic shutdown and restart.
Command Reference Example The following example will write the current configuration information to the console: UBR04# write terminal Building configuration... Current configuration: ! version 11.1 service udp-small-servers service tcp-small-servers ! hostname WMCS01 ! enable password a23d56 ! username user220 ! interface FastEthernet0/0 no ip address no ip route-cache shutdown media-type MII ! ip name-server 192.168.168.1 ip name-server 192.168.168.181 ip name-server 192.168.168.
Command Reference • radio operating-band—To specify the radio operating band and transmit/receive frequencies within that band • radio cable-loss—To enter the effective IF cable loss • radio antenna-alignment—To align the receive antenna with the transmitter • radio transmit-power—To configure the antenna to transmit a specific amount of power loopback Use this command in interface configuration mode to configure the specified module to loopback its data path at the specified subsystem.

Command Reference Note Use the show running-configuration interface radio slot/port command to display the current setting. radio receive-antennas {1 | 2} no radio receive-antennas Example The following example configures the wireless modem card to use two receive antennas: UBR04(config-if)# radio receive-antennas 2 radio master Use this command in interface configuration mode to configure the wireless modem card to operate as the master radio.
Command Reference radio channel-setup Use this command in interface configuration mode to adjust bandwidth and throughput to increase the reliability of the link. For a selected bandwidth, data throughput can be reduced to increase reliability. This command can be entered at any time. If the link is up when it is entered, the command will take effect with the next shut/no shut. If the link is down when it is entered, the command will take effect with the next no shut.
Command Reference broadband fixed wireless systems have two settings for the amount of error-correction coding. The SINR required for a link is reduced by 5 to 6 dB when the setting with the most error-correction coding is used (see Table 8 and Table 9). Multipath delay spread occurs when the signal arrives at the receiver by multiple paths with differing path lengths. Signals that take longer paths will arrive later than signals that take shorter paths.
Command Reference Table 9 6-MHz Bandwidth Values (continued) Throughput Setting High Medium Low Error-correction coding 7/8-rate 7/8-rate 1/2-rate Cyclic-prefix setting short long long Simplified Procedure to Choose Throughput Setting These steps help determine the throughput setting by trying each setting and choosing the one that gives acceptable error performance: Step 1 Initiate the link using the low throughput setting. UBR04(config-if) # Step 2 Clear the link-metrics counters.
Command Reference Step 7 If the link meets the required thresholds using the high setting, use the high setting for normal operations. Expert Procedure to Choose Throughput Setting These steps help determine the throughput setting by measuring the multipath delay spread and SINR, then choosing the appropriate throughput setting. Step 1 Initiate the link using the low throughput setting. UBR04(config-if) # radio channel-setup bandwidth 12.
Command Reference Selecting the Transmit and Receive Frequencies Use the channel-setup parameters to select the required bandwidth and data throughput prior to specifying the operating-band. Transmit and receive frequencies must be consistent with the bandwidth the radio has been configured to operate in using the channel-setup command, and must fall within the passband of the duplexer used in the transverter. Table 10 provides center frequencies for the U-NII band.
Command Reference radio cable-loss Use this command in interface configuration mode to enter the effective cable loss (measured in dB at 400 MHz) of the cable between the wireless modem card and the specified wireless transverter, including the power feed panel, connectors, and lightning protection. Use the no version of the command to remove the setting. Table 11 gives an example of estimated cable, connector, and equipment loss for a typical installation.
Command Reference Example The following example adjusts the effective cable loss parameter for antenna 1 to 12 dB: UBR04(config-if)# radio cable-loss 1 12 radio antenna-alignment Use this command in interface configuration mode to align the receive antenna to the transmitter. After the next no shut, a separate voltage is sent to the alignment port located on each wireless transverter in the link, which can be read with a DC voltmeter.
Command Reference Syntax Description power Positive number representing power stated in dBm. Transmit power range for U-NII is between 4 and 24 dBm. Example The following example sets the U-NII transmit power to +20 dBm: UBR04(config-if)# radio transmit-power 20 Operating Commands These commands are used during the normal operation of the broadband fixed wireless system to configure baseline encryption, duplexer characteristics, LEDs and Automatic Repeat Query (ARQ).
Command Reference radio privacy {enable | auth-wait-time secs | reauth-wait-time secs | auth-grace-time secs | op-wait-time secs | rekey-wait-time secs | tek-grace-time secs | auth-lifetime secs | tek-lifetime secs} no radio privacy Syntax Description auth-wait-time The number of seconds the slave radio will wait before issuing a new authorization request to the master radio. reauth-wait-time The number of seconds the slave radio will wait before issuing a new reauthorization request to the master.
Command Reference Syntax Description antenna_num Enter 1 (main antenna) or 2 (diversity antenna). Identifies the antenna to which the duplexer is connected. PartNum A string representing the duplexer’s part number LoPassbandRange Identifies the duplexer’s low frequency range. This range is lower than the range specified in the HiPassbandRange parameter. HiPassbandRange Identifies the duplexer’s high frequency range. This range is higher than the range specified in the LoPassbandRange parameter.
Command Reference led-minor-alarm Indicates the occurrence of a minor alarm in the radio subsystem. Unless the default mode is overridden, the LED will remain illuminated for the duration of the alarm. latchLedOptions {latch | off | green | yellow | blinkGreen | blinkYellow | blinkBoth} latch The system will turn the LED on indicating an alarm condition; the operator must turn it off by entering the radio led latchLeds latch command.
Command Reference radio arq (automatic repeat query) Use these commands in interface configuration mode to configure the Automatic Repeat Query mechanism on the wireless modem card. With ARQ, the transmitter resends data that is received in error at the receiver. This allows the radio link to run at a substantially lower error rate in RF channels with rapid fading or bursty interference. Enabling requires a small amount of additional overhead and increases the latency of the link.
Command Reference Syntax Description pctBw Positive number representing the highest percentage of the link bandwidth to be used for the ARQ mechanism. The value may be 1 to 5000, representing 0.01 to 50 percent of the available bandwidth. The default value is 1250. Note Regardless of the pctBw setting, link bandwidth is only consumed by ARQ when tdata errors need to be corrected. dataLatency Positive number specifying the expected latency value for normal data.
Command Reference ARQPeakBitRate The maximum possible peak bit rate that the link can handle based on the current channel-parameter and ARQ settings. ARQMinBitRate The minimum bit rate that may be seen on the link based on the current channel-parameter and ARQ settings. ARQMaxLatencyJitter The maximum jitter expected on this link based on the current configuration.
Command Reference Use the radio metrics-threshold 1hour command to configure limits on the ES, SES, CSES, and Degraded Minutes DM. When these limits are exceeded in a 1-hour period, alarms will be generated to notify the user. Minor alarms are generated and displayed on the console when the specified 1-hour threshold is exceeded. Use the radio metrics-threshold 24hour command to configure limits on the ES, SES, CSES, and DM.
Command Reference Example The following example will configure the link so that: • If more than 3 codeword errors are detected in a given second, that second will be treated as an errored second. • If the number of errors detected in one second is between 30 and 150, that second will be flagged as a degraded second. • If more than 150 errors are detected in one second, that second will be flagged as a severely errored second.

Command Reference CWRP2P_LOG_BPKM_COPY_FAILED CWRP2P_LOG_NO_MEMORY CWRP2P_LOG_PRIVACY_UNKNOWN_RX_QUEUE_EVENT CWRP2P_LOG_PRIVACY_UNKNOWN_BOOLEAN_EVENT CWRP2P_LOG_PRIVACY_UNKNOWN_MAJOR_EVENT CWRP2P_LOG_PRIVACY_PROCESS_EXITING CWRP2P_LOG_PRIVACY_BAD_PACKET_LENGTH CWRP2P_LOG_PRIVACY_BAD_MSG_ID CWRP2P_LOG_PRIVACY_BAD_MESSAGE_CODE CWRP2P_LOG_PRIVACY_KEY_SEQUENCE ERROR CWRP2P_LOG_PRIVACY_REAUTH_REQUEST CWRP2P_LOG_PRIVACY_FSM_BAD_STATE_EVENT CWRP2P_LOG_PRIVACY_FSM_NO_TRANSITION CWRP2P_LOG_PRIVACY_KEK_FSM_EVENT CWR
Command Reference Link Management Messages This command causes the contents of the Link Management and BPI messages to be dumped in a formatted fashion as they are transmitted or received. Note The meanings of these fields are documented in the Data Over Cable System Interface Specification (DOCSIS) standards.
Command Reference symbol Logging related to symbols generated from an image. decompressor Logging related to the cwrDecompressor layer used by the cwrImage layer. download_fsm Logging for the download state machine. matlab Logging for the matlab task. queue Logging for the cwrQueue layer. dspmsgdown Tracing for messages sent down to the DSPs from the host. dspmsgup Tracing for messages sent up to the host from the DSPs. subsystem Subsystem messages or problems.
Command Reference Syntax Description protocol {mem | tftp | flash} host IP address. directory Directory name. (No embedded spaces accepted.) filename Name of image file. Example The following command selects the image disp1a.img at the address 192.168.33.44 to be added to the repository: UBR04# radio image-add tftp://192.168.33.44/myDspImages/dsp1a.img radio image-move Use this command in privileged EXEC mode to move the specified image to the beginning of the repository list of images.
Command Reference If a particular chip is identified, the details of the image to be loaded on that chip are displayed. If no chip name is specified, the current radio configuration is retrieved for every chip on the modem card. All the images in the repository are compared. The image that provides the closest match in capability is selected, and the details of that image are displayed.
Command Reference radio snapshot A snapshot is a specified amount of data captured from the wireless modem card. Use these commands in privileged configuration mode to manipulate snapshots on the modem card. Use the radio snapshot command to create a snapshot specification. When this command is entered, the specification is created and the data is captured. Use the no form of the command to delete a specification and its associated data.
Command Reference Note The Tx and Rx types cannot be mixed. Rx and Sync types can be mixed. When a radio snapshot command is issued, up to four signal attributes may be requested at once, one from each set.
Command Reference rx-spectrum-ant1-y1k (0x04) Represents a snapshot of the spectrum of the received signal for RF resource 1. For every sample, the real and imaginary components are captured. Units: (I, q) Value: 32-bit quantities rx-spectrum-ant2-y2k (0x08) Represents a snapshot of the spectrum of the received signal for RF resource 2. For every sample, the real and imaginary components are captured.
Command Reference tx-round-output (0x800) Represents a snapshot of the Rounded Constellation signal for the transmitted data. For every sample, the real and imaginary components are captured. Units: (I, q) Value: 32-bit quantities sync-burst-timecost-func (0x1000) Represents the timing cost function for Sync bursts. Units: Real Values Value: 32-bit quantities sync-freq-offset-costfunc (0x2000) Represents a snapshot of the frequency offsets.
Command Reference Syntax Description dspId {dsprx1a (Receive DSP 1a) | dsprx1b (Receive DSP 1b) | dsprx2a (Receive DSP 2a) | dsprx2b (Receive DSP 2b) | dsprx3a (Receive DSP 3a) | dsprx3b (Receive DSP 3b) | dsptx1 (Transmit DSP 1) | dsptx2 (Transmit DSP 2)} outputType {rx-rawburst-ant1-y1n | rx-rawburst-ant1-y2n | rx-spectrum-ant1-y1k | rx-spectrum-ant1-y2k | rx-timedomainchannel-ant1-h1n | rx-timedomainchannel-ant2-h2n | rx-freqdomainchannel-ant1-h1k | rx-freqdomainchannel-ant2-h2k | rx-constellation-zh
Command Reference Note Up to 1024 32-bit words are available for all timeline parameters on a single DSP. Each timeline requires (tlsize+1) * 2 words. The attributes in in, inr, and constVariance can be captured on any DSP, while the others can be captured only on certain DSPs. Distributing timeline requests across DSPs provides better memory utilization. Selecting the Correct DSP In most cases, the default DSP should provide acceptable results.
Command Reference constVariance (Constellation Variance) The average energy of the constellation error signal—the error between the received (noisy) constellation symbol and the nearest ideal constellation symbol. Constellation Variance is a measure of the Signal to Interference plus Noise ratio (SINR) for that tone. On a single antenna system, it represents (SINR)-1. On a dual antenna system, it represents (SINR)-1 after antenna combining.
Command Reference presummationShift If decimationFactor is specified, then successive data samples get added. This can potentially cause an overflow. The presummationShift value specifies the number of bits by which the data sample should be right-shifted before being added. Specifying a presummationShift value will result in less precise individual data samples but provides a mechanism to analyze the behavior over longer duration of time. pss (0 . .
Command Reference negCrossing The limit that applies only when the threshParam is decreasing in value. postTrigBufMgt Specifies the position of the trigger in the data collected. If it is 1, then most of the data collected prior to the trigger is returned. If it is 2, most of the data returned is captured after the occurrence of the trigger. Example The following example configures a timeline specification. The collection process starts as soon as the command succeeds.
Command Reference show interfaces radio (tldata) Use this command in privileged EXEC mode to display the timeline data collected for the identified specifications. show interfaces radio slot/port tldata [statParam antenna_num [dsp dspId]] Syntax Description Refer to radio timeline for syntax descriptions.
