GIGABIT/FAST ETHERNET SWITCH TYPE SW3 (DIN)

USER GUIDE - M0SW3D1905Iv04 - V04 May 2019
FIGURE 37a) shows a network made up by four level-2 switches, which in turn are
connected to a router. Host A is a multicast message emitter, and the Hosts B and C are
multicast receivers belonging to the same group as the Host A. The router will route the
multicast traffic only to the network sections where the Hosts B and C are found, while the
level-2 switches will transmit traffic to all the hosts connected to their interfaces by flood.
FIGURE 37b) shows a network using the GARP/GMRP or IGMP Snooping mechanism in
its level-2 devices. As shown in the figure, in this case only the hosts that belong to the
diffusion group receive the multicast traffic.

Static
By means of this option, the user can manually configure the interfaces that will propagate
each of the indicated multicast MAC addresses.
In networks with multiple switches, the configuration must be done in each of them.

The parameters for creating the list of multicast MACs are the following:
•
#.
Tabulate element identifier. Not relevant.
•
Address.
The multicast MAC address.
•
Ports.
Port/s that will transmit traffic with multicast MAC address. A group of discreet
ports is configured with the identifier of each one, separated by a comma, without
spaces. If a range is to be included, the initial and final port identifiers are separated
by a dash. The value
any
means the port is not relevant.
•
VLANs.
Numeric identifier of the VLANs defined on the equipment on which the
MAC address will be transmitted (VID fields in the
VLANs
menu). A group of discreet
vlans is configured with the identifier of each one, separated by a comma, without
spaces. If a range is to be included, the initial and final vlan identifiers are separated
by a dash. The value
all
means the vlan is not relevant. Example: in equipment with
the
vlan1
,
vlan3
and
vlan4
defined, the group of numerical identifiers will be
1,3,4
.
