Task 6: Configuring radio parameters
To configure Multicast VC, the AP must have this enabled. This can be enabled in the
“Multicast Data Control” section (under Configuration => Radio tab). The default value
is “Disable”. If set to the
default
value, all multicast packets are transmitted over the
Broadcast VC data path. To enable, select the data rate that is desired for the Multicast VC
Data Rate parameter and click Save Changes button. The radio requires no reboot after
any changes to this parameter.
The multicast VC allows three different parameters to be configured on the AP. These can
be changed on the fly and are saved on the flash memory.
If the Multicast VC Data Rate is set to a modulation that the radio is not currently
capable of or operates in non-permitted channel conditions, multicast data is sent but not
received.
Ex: If Multicast VC Data Rate is set to 6x and the channel conditions only permit 4x mode
of operation, then multicast data is sent at 6x modulation but the SM will not receive the
data.
Actual Multicast CIR honored by the AP = Configured Multicast CINR/ (Multicast
Repeat Count + 1).
Increasing the Multicast data rate has no impact on the Unicast data rate.
For multicast and unicast traffic mix scenario examples, see Table 34.

New statistics have been added to the Data VC tab (under Statistics => Data VC). The
table displays the multicast row on the PMP450i AP. The SM displays the multicast row if it
is a PMP450i.
