Note
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.
Note
The PMP 450 AP supports up to 119 VCs (instead of 238 VCs) when configured for 30
MHz channel bandwidth or 5 ms Frame Period. This limitation is not applicable for
PMP 450i Series.
Note
 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 147.

The statistics have been added to the Data VC page (under Statistics > Data VC). The table displays
the multicast row on the PMP 450 Platform Family AP. The SM displays the multicast row if it is a
PMP 450 Platform Family.

The AP and SM display Transmit and Receive Multicast Data Count (under the Statistics >
Scheduler page), as shown in Figure 131.
