Figure 6: Enable Large VC data Q via Configuration => Radio on SM, BHM and BHS.
If an operator is experiencing packet loss in the uplink due to bursting IP traffic and the overall
traffic rate is less than or equal to the uplink capacity of the radio system, then the large VC data
Q should be enabled.
For example, a PTP 20 Mbps BH has a video camera connected to the BH Slave (BHS) uplink.
To check if packets are being lost at the BHS RF interface the operator should check the
“outdiscards Count” at the Statistics->Radio page of the BHS. If this count is incrementing, then
packets are being lost at the RF interface of the BHS and the Large VC data Q should be
enabled. In the figure below, the outdiscards Count shows 455 discard events since the counter
was reset, indicating that probably system performance would be improved by the Large VC data
Q.

The large VC data Q option can be enabled via the Configuration => Radio page on SMs, BH
Masters, and BH Slaves. It is not available for APs.
