Port Port entries may be marked as:
- : (Normal) Uses GVRP to determine port membership.
S : (Stat ic) Adds port as a static entry. GVRP protocol messages
are still forwarded through this port.
R : (Registration Fixed) Adds port as a static entry. GVRP protocol
is disabled.
X : (Forbidden) Disables GVRP for this VLAN on the specified port.
If a removed port is no longer assigned to any other group as an
untagged port, it will automatically be assigned to VLAN group 1 as
untagged.

2.5.5.Configuring IGMP Snooping Multicasting is used to support real-time applications such as videoconferencing or
streaming audio. A multicast server does not have to establish a separate connection
with each client. It merely broadcasts its service to the network, and any hosts which
want to receive the multicast register with their local multicast switch / router. Although
this approach reduces the network overhead required by a multicast server, the
broadcast traffic must be carefully filtered at every multicast switch / router it passes
through to ensure that traffic is only passed on to the hosts which subscribed to this
service.
This switch uses IGMP (Internet Group Management Protocol) Snooping to monitor any
attached hosts which want to receive a specific multicast service. It looks up the IP
Multicast Group used for this service, and adds to it any port that received a similar
request .
You can use the IGMP Snooping Configuration screen to configure multicast filtering as
shown below.
