•
Mode
- Indicates the filtering mode maintained per (VLAN ID, port number, Group Address)

Exclude
. In IGMPv3, a host can send a membership report
that includes a list of source addresses. When the host sends a membership report in
INCLUDE mode, the host is interested in group multicast traffic only from those sources in the
source address list. If a host sends a membership report in EXCLUDE mode, the host is
interested in group multicast traffic from any source
except
the sources in the source address
list.
A host can also send an EXCLUDE report in which the source-list parameter is empty, which is
known as an EXCLUDE NULL report.
An EXCLUDE NULL report indicates that the host
wants to join the multicast group and receive packets from all sources
•
Source Address
- IP Address of the source. Currently, the maximum number of IPv4 source
address for filtering (per group) is 8. When there is no any source filtering address, the text
"None" is shown in the Source Address field.
•

Allow
or
Deny;
checking the source address of the received multicast
packets, permitting or denying packets from those multicast source Addresses.
