• VLAN
This stands for Virtual Local Area Network. A virtual
network is constructed separately from the physical
connections. When there are multiple networks of
differing types, setting up a VLAN allows a logically
separate network to be constructed that shares the
same physical switches.
A VLAN can be either a "Port-based VLAN" which
constructs groups using a physical connection for
each port, or a "Tag VLAN" which differentiates VLAN
groups by assigning a tag to each Ethernet frame.
In the case of a port-based VLAN, each VLAN requires
a connection to communicate with another switch.
Using a tag VLAN allows multiple VLANs to be
combined into a single trunk connection (cable) that
connects switches, ensure that the total amount of
data does not exceed 1 Gbps for the LAN ports or
10 Gbps for the 10GBASE-SR/LR ports. The VLAN
preset A and B of the SWP2 use tag VLAN.

• Link aggregation
Link aggregation is a function that bundles multiple
LAN/SFP+ ports that connect network devices, and
treats them as a single logical interface in order to
expand the communication bandwidth. A group that is
bundled using link aggregation is called a link
aggregation group (LAG).
Link aggregation is a technology that is useful when
multiple communications are occurring. The
communications can be distributed between the
aggregated connections by using a load balancing
function. Since load balancing distributes the load
according to IP address, we recommend that you fix
the IP addresses of each device in order to stabilize
load balancing.
Even if a problem occurs on one of the LAN/SFP+
ports that are bundled by link aggregation, so that this
port is unable to communicate, communication will
continue via the remaining ports.
• Trunk
This function adds tags to multiple VLANs so that they
can be transmitted and received via a single
connection. When one SWP2 transmits VLAN 1 data
via the trunk connection, the SWP2 unit that receives
this will transmit the data only to the port that
corresponds to its own VLAN 1.
Communication speed for a metal trunk connection on
the SWP2's VLAN preset B is 1 Gbps per cable. If
there is only one cable, and the total bandwidth
passing through the trunk connection exceeds
1 Gbps, packets will be delayed or dropped. Some of
the SWP2's VLAN presets enable link aggregation of
the trunk connection. If the bandwidth will exceed
1 Gbps for a LAN port or 10 Gbps for a 10GBASE-SR/
LR port, or if you want to provide redundancy to guard
against cable breakage, you should use two trunk
cables.
