Command Reference
Syntax Description
Example
The following command sets the ARQ mechanism for 0.01% of the bandwidth, a 10-millisecond data
latency value, and 24 consecutive ARQ codewords:
UBR04(config-if)# radio arq 1 10 24
show interfaces radio (arq)
Use this command in privileged EXEC mode to display the current ARQ configuration on the wireless
modem card.
show interfaces radio slot/port arq
Syntax Description
Display Elements
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. Latency
values are measured in milliseconds. The default value is 11 ms.
BurstSize Positive number specifying the maximum number of consecutive ARQ codewords
that will be transmitted. Smaller values result in lower jitter. The default value is 8.
slot Positive integer representing the Cisco uBR7200 series slot number.
port Positive integer representing the port number on that slot.
pctBW The maximum percent link bandwidth being used for ARQ.
voiceLatency Hardware will restrict the maximum latency for voice data to this value.
dataLatency Hardware will restrict the maximum latency for packet data to this value.
BurstSize Currently configured burst size, in number of codewords.
OnOff Whether ARQ is turned on or off.
