Name Displays the name of the network/VLAN.
Config Displays the configuration: Native (____) or
Customized. (Networks may be created in “Settings >
Networks” on page 9.)

• Name Enter a name to identify this network/VLAN.
• Native Network A native network has a Port VLAN
Identifier (PVID), which identifies the default VLAN. A
switch assigned to a native network participates in the
VLAN of that native network.
The Switch accepts tagged and untagged packets
in the ingress direction, and the untagged packets
are assigned to the VLAN of the native network. For
example, if the PVID is VLAN 30, then all untagged
packets are assigned to VLAN 30. In the egress direction,
the native network packets are stripped of the VLAN 30
header and exit as untagged packets.
This table lists how the packets are handled:

Ingress Action Egress
Tagged Accepted Remains tagged Sent out as tagged
Untagged Accepted Assigned to VLAN

out as untagged
Each physical port can have multiple networks attached;
however, only one of them can be native (untagged).
Select the appropriate native network. (Additional
networks may be created in “Settings > Networks” on
page 9.)
• Tagged Networks For a Switch belonging to a tagged
network, the packets will be tagged in both ingress and
egress directions. For example, the native network is
LAN with VLAN 1 as the PVID. The switch is connected to
an AP with two tagged networks:
• VLAN 20: corporate
• VLAN 30: guest
This table lists how the packets are handled:
Packet
Type
Ingress Action Egress
Untagged Accepted Assigned to VLAN 1 VLAN header
removed and sent
out as untagged
Tagged as
VLAN 20
Accepted Remains tagged Sent out tagged as
VLAN 20
Tagged as
VLAN 30
Accepted Remains tagged Sent out tagged as
VLAN 30
The proper use of VLANs isolates the traffic of each
VLAN. The guest traffic on VLAN 30 will be kept separate
from the traffic on the corporate network.
Select the appropriate tagged network. (Additional
networks may be created in “Settings > Networks” on
page 9.)

• Cancel Click Cancel to discard changes.
Services
Network Group A network group defines the
management VLAN for the Switch. Select the appropriate
network group.
Enable Jumbo Frame Disabled by default. The Maximum
Transmission Unit (MTU) is the maximum packet size (in
bytes) that a network interface can transmit. A jumbo
frame is larger than the standard Ethernet frame with an
MTU of 1500. Jumbo frames are typically used for Gigabit
Ethernet connections. If you enable this option, then this
port handles jumbo frames and forwards them.
