MultiLink Trunking (MLT) is a mechanism to distribute multicast streams over a multilink trunk and achieve an even distribution of the streams. The distribution is based on source-subnet and group addresses. In applications like television distribution, multicast traffic distribution is particularly important because the bandwidth requirements are substantial when you use a large number of television streams.
The switch enables this feature by default and you can not change the configuration.
Traffic distribution distributes the streams on the multilink trunk links if an MLT configuration change occurs. For example, you can add or delete ports.
This feature distributes active streams according to the distribution algorithm on the multilink trunk links. This distribution can cause minor traffic interruptions. To minimize the effect of distribution of multicast traffic on the multilink trunks, the implementation does not move the streams to the appropriate links at the same time. Instead, it distributes a few streams at every time tick of the system.
To that end, after a multilink trunk port becomes inactive, this feature distributes all the streams on the multilink trunk ports based on the assignment provided by the distribution algorithm.
By default, distribution is enabled and you can not change the configuration.
