SWP2 Owner’s Manual

Caution when using this unit
together with another
manufacturer’s switch
Dante supports both IGMP V2 and V3, but you must set
all switches in the same network to operate using the
same version.
If the SWP2 starts up with DANTE settings, it operates
using IGMP V3. In this case, if the network includes
even one switch that is operating with IGMP V2,
problems such as dropouts in the sound might occur.
• Switch 2 and 3 (VLAN PRESET)
Specifies the VLAN preset that is used when switch 1
is in the [DANTE] position. This setting is ignored if
switch 1 is set to [USER].
If you change the settings via the web GUI or a
command, the settings are applied temporarily but is
not stored; the next time the unit starts up, it returns
to the VLAN preset setting.
In the tables, “1,” “2,” “Tr1,” and “Tr2” respectively
indicate VLAN 1, VLAN 2, trunk (LAG1), and trunk
(LAG2).
For an explanation of VLAN, trunk, link aggregation,
and LAG, refer to Terms on page 10. For details, you
can download technical reference material (HTML).
(*1) In the VLAN presets, the IGMP Snooping function is
turned on except for VLAN 2 in presets A and B,
preventing multicast communication such as Dante
’
s
multicast flow from being forwarded to unnecessary
routes. For this reason, in the case of A or B you
should use the VLAN 1 port for audio signals such as
Dante, and use the VLAN 2 port for control signals.
(*2) If you use setting C, connect the computer that is
using Yamaha Audio Network Monitor to the VLAN 1
port.
7 [CONSOLE (RS-232C)] port
This is an RJ-45 port used to specify commands.
Use an RJ-45/DB-9 serial cable to connect this to the
RS-232C port (COM port) of your computer. Use an
RJ-45/DB-9 serial cable that is wired as described in
“Specifications.”
