switch to apply the new configuration may vary from one switch to the other. Most
switches implement and include FASTLEAVE configuration option. When enabled, it
takes much less time for a particular port to leave a multicast group to assign the port to
a different multicast group. The end results are a noticeably shorter video switching
time. Aurora recommends to always enable the FASTLEAVE option when available.
With FASTLEAVE option, seamless switching is possible for 4K video sources. Without
FASTLEAVE option, 'seamless' switching is limited to 1080P 60 Hz video signals.
