Mode
Global Configuration
Usage
If this command is enabled, the device will forward the first packets in a multicast
stream that create the multicast route, possibly causing degradation in the quality
of the multicast stream, such as the pixelation of video and audio data.
NOTE
:
If you use this command, ensure that the
ip igmp snooping
command is enabled,
the default setting, otherwise the device will not process the first packets of the
multicast stream correctly.
The device will forward the first multicast packets to all interfaces which are on the
same VLAN as those which asked for this multicast group.

commands:
awplus#
configure terminal
awplus(config)#
ip multicast forward-first-packet
To disable the forwarding of the first multicast packets, use the following
commands:
