Layer 2 Switch (L2SW)
If there are no requirements for network monitoring or security strengthening, you can
connect Vnet/IP stations to any ports of the recommended layer 2 switch in its default
state. Even if you use the layer 2 switch as a trunk port between layer 2 switches or with
layer 3 switches, you do not have to use a cross cable or change any of the layer 2 switch
settings.
To connect recommended layer 2 switches with optical fiber cables, use combo ports that
can use an SFP. You must use the recommended SFP product that is implemented in this
layer 2 switch. You do not have to change the settings of layer 2 switches because SFP
combo ports automatically adjust to the optical interface.

4.2
Layer 3 Switch (L3SW)
The routing protocol parameters for connecting to Vnet/IP are already configured in the
recommended layer 3 switch. By default, the IP addresses of the ports are also configured
to enable connection to domains. You can enable inter-domain communication by
connecting the layer 2 switch of each domain to the port that matches the domain
number. There is no special configuration required. (*1)
In Vnet/IP, the network address is different for bus 1 and bus 2. Therefore, there are two
types of recommended layer 3 switches, one for bus 1 and another one for bus 2. You
must differentiate the use of layer 3 switches for each bus.
To connect recommended layer 3 switches with optical fiber cables, use combo ports that
can use SFP. You must use the recommended SFP product that is implemented in this
layer 3 switch. You do not have to change the settings of layer 3 switches because SFP
combo ports automatically adjust to the optical interface.
*1:
Change the settings of layer 3 switches if you want to connect domains in a cascade.
