The State:<Enabled> field can be toggled between Enabled and
Disabled using the space bar, and is used to enable or disable
PIM-DM for the IP interface. The default is Disabled.

Static Router Port

Note:
' router port' in Layer 2 Only mode and in IP Routing
mode.
Note:
A router port allows UDP multicast and IGMP
packets to be forwarded to a designated port regardless of
VLAN configuration.
Note: A router port functions within layer 2 of the OSI
model.
Multicasting section of this manual above because of the
possible confusion caused by the term ' router port' when
compared to a traditional router.
A static router port is a port that has a router attached to it.
Generally, this router would have a connection to a WAN or to
the Internet.
packets coming from the router to be propagated through the
network, as well as allowing multicast messages coming from the
network to be propagated to the router.
The purpose of a router port is to enable UDP multicast packets,
and IGMP multicast group membership messages to reach
multiple ports of a multiport router. Routers do not implement
IGMP snooping or transmit/forward IGMP report packets. Thus,
forwarding all IP UDP multicast packets to a static router port
on the DES-3326 guarantees that all ports of a multiport router –
attached to the DES-3326 – can reach all multicast group
members through the attached router' s other ports.
