Ingress Multicast Path Management parameters
Administrative BW (kbps)
The Administrative BW parameter specifies the multicast channel's administrative bandwidth in kilo-bits per second. The range is from 0 to 40 000 000 kbps. The default is 0.
The XML property name for this parameter varies depending on where it is set, namely at the bundle, channel range, or channel override level.

Black Hole Rate (kbps)
The Black Hole Rate parameter specifies at which current rate a channel (including channels within a channel range or bundle) should be placed in the black-hole state (packets are dropped). This value can only be set when the BW Decision parameter is set to Dynamic. The range is 0 to 40 000 000. The default is 0, which means never.
The XML property name for this parameter varies depending on where it is set, namely at the bundle, channel range, or channel override level.

BW Decision
The BW Decision parameter specifies how the multicast ingress path manager determines the amount of bandwidth required by a multicast channel, including channels within a channel range or bundle.
The XML property name and default value for this parameter varies depending on where it is set, namely at the bundle, channel range, or channel override level.

Explicit Path
The Explicit Path parameter specifies an explicit ingress switch fabric multicast path for the channels (including those in a range or a bundle). If the parameter is set to None, the Multicast Path Manager dynamically places channels on the most optimal switch fabric paths.
The options are:

Falling Delay (seconds)
The Falling Delay parameter specifies the value the bandwidth manager uses as a threshold to hold on to the previous highest bandwidth until the delay time has expired, while operating in dynamic bandwidth mode. This allows the bandwidth manager to ignore momentary drops in channel bandwidth. This value can only be set if BW Decision is set to Dynamic. A value of 0 specifies that a non-zero value of the parent is applied.
The XML property name for this parameter varies depending on where it is set, namely at the bundle, channel range, or channel override level.

Preference Level
The Preference Level parameter specifies the relative preference level for multicast channels. The preference of a channel (including those in a bundle or range) specifies its relative importance over other multicast channels. Eight levels of preference are supported: 0 through 7. Preference value 7 indicates the highest preference level.
The XML property name and default value for this parameter varies depending on where it is set, namely at the bundle, channel range, or channel override level.
