DES-3326 Layer 3 Fast Ethernet Switch User’s Guide
Click the IEEE802.1Q Multicast Forwarding link on the Multicasting menu:
Figure 7-39. Setup IEEE 802.1Q Multicast Forwarding window
When the switch is in Layer 2 operating mode, IEEE 802.1Q multicast forwarding allows the static
entry of multicast MAC addresses, which will be sources of multicast packets, and switch port
numbers, to which these multicast packets will be forwarded. The ports that can be chosen as the
destination for multicast packets from the above MAC multicast address, are limited to the ports
belonging to the VLAN that corresponds to the VID entered in the VID field.
Each port of a given VLAN can be configured as an egress member, a forbidden non-member, or as a
non-member of the multicast group that will receive multicast packets from the multicast MAC address,
by clicking the click-box below each port of the VLAN to the appropriate code.
The following fields can be set:
Parameter Description
MAC Address
Allows the entry of the MAC address
of a static multicast group member.
VID
Allows the specification of the VLAN
ID (VID) of the VLAN the static
multicast group member belongs to.
Egress
Egress Member - specifies the port
as being a static member of the
multicast group. Egress Member
Ports are ports that will be
transmitting traffic for the multicast
group.
Forbidden
Forbidden Non-Member - specifies
the port as not being a member of
the multicast group and that the port
is forbidden from becoming a
member of the multicast group
dynamically.
Static Router Port Settings
A static router port is a port that has a multicast router attached to it. Generally, this router would
have a connection to a WAN or to the Internet. Establishing a router port will allow multicast packets
