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).
SWP1-8/SWP1-8MMF
SWP1-16MMF
(*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 LAN Monitor to the VLAN 1 port.
The SWP1-8’s 9 and 10, the SWP1-8MMF’s 10, and
the SWP1-16MMF’s 18 are available only if the MMF-
SWP1 option is installed.
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.”
8 [POWER] indicator
This is lit when the SWP1 is powered-on.
