MCCTH – Multicast Threshold Control
RDRC0 – WRED Rate Control 0
RDRC1 – WRED Rate Control 1
RDRC2 – WRED Rate Control 2
Global congestion control threshold on the multicast granule count. Exceeding
the MCCTH threshold is considered as an indication of multicast resources being
low.
Used to trigger RED at B% when when total multicast granule count reaches
MCCTH. Granularity is 16 granule (Default 0x3).
