Dedicated Multicast Virtual Circuit (VC)
A Multicast VC allows to configure multicast packets to be transmitted over a dedicated channel at a
configurable rate of 1X, 2X, 4X or 8X. This feature is available only for the PMP 450 and PMP 450i and is
not backward compatible with PMP 430 series of radios.
To configure Multicast VC, the AP must have this enabled. This can be enabled in the “Multicast Data
Control” section (under Configuration > Radio page). 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.
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/450m Series.
Note
•
Actual Multicast CIR honored by the AP = Configured Multicast CIR/ (Multicast
Repeat Count + 1).
•
Increasing the Multicast data rate has no impact on the Unicast data rate.
