UniFi Switch – Configuration
Click Configuration to configure the alias, network/VLANs,
services, and network settings. You can also use this tab
to copy another switch’s configuration to this Switch,
perform a custom upgrade, gain terminal access to the
Switch, or remove the Switch from management.
General
Alias Displays the customizable name or identifier of the
Switch. The Alias is also known as the host name.
Save Click Save to apply your change.
Cancel Click Cancel to discard changes.
Networks/VLANs
The Networks/VLANs section displays the available VLANs
for configuration on this switch, as defined under Settings
> Networks. It also displays VLAN groupings that can be
managed here, which apply site-wide. VLAN groupings
allow creating a combination of native networks
(untagged) and tagged networks (tagged VLANs) for
switch ports. The groupings configured here are then
available for assignment to switch ports on the switch’s
Port configuration tab.
Create Click
CREATE
to add a new entry. Go to the “Create
New Network/VLAN” on page 98 section below.
Name Displays the name of the network/VLAN.
Config Displays the configuration: Native (____) or
Customized. (Networks may be created in “Settings >
Controller” on page 41.)
Actions Click a button to perform the desired action:
• View Click to view the default network.
• Edit Click to edit the network/VLAN entry. (Not
available for the default network.)
• Delete Click to delete the network/VLAN entry. (Not
available for the default network.)
Create New Network/VLAN
• Name Enter a name to identify this network/VLAN.
• Native Network The Native Network specifies the
default VLAN, or Port VLAN Identifier (PVID), for the
switch port. This determines the VLAN to be used for
untagged traffic on that port. Most client devices do not
VLAN-tag traffic; they will therefore only use the Native
Network on their port.
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:
Packet
Type
Ingress Action Egress
Tagged Accepted Remains tagged Sent out as tagged
Untagged Accepted Assigned to VLAN
of native network
VLAN header
removed and sent
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 > Controller” on
page 41.)
