UniFi Controller User Guide
DPI (Beta) Deep Packet Inspection (DPI) is more
advanced than conventional Stateful Packet Inspection
(SPI) filtering for traffic analysis. Ubiquiti's proprietary
DPI engine includes the latest application identification
signatures to track which applications (and IP addresses)
are using the most bandwidth.
• Clear DPI Counters Click to delete all collected DPI
data. Click Confirm or Cancel.
Note: The DPI feature requires use of the UniFi
Security Gateway.
Port Remapping (Beta)
When enabled, the VOIP port on
the UniFi Security Gateway, model USG, will be remapped
as a WAN2 port.
Uplink Connectivity Monitor
the managed APs, either wired or wireless, by checking to
see if the gateway/custom IP can be reached. The monitor
and wireless uplink capability are enabled by default.
• Enable Automatic Uplink Failover
to have the UniFi Controller automatically select a new
wireless uplink if the original uplink fails. This allows
the UniFi APs to switch to alternative uplinks/mesh
configurations if a node fails.
• Default Gateway Enabled by default. All managed
APs will use the gateway of the AP that is providing IP
information, either by DHCP or Static designation.
Custom IP
• Click to specify an IP address.
- Uplink IP Address All managed APs will use the IP
address you enter.
SNMP Select this option to activate the SNMP
(Simple Network Monitor Protocol) agent. SNMP
is an application layer protocol that facilitates the
exchange of management information between
network devices. Network administrators use SNMP
to monitor network-attached devices for issues that
warrant attention.
Community String
• Specify the SNMP community
string. It is required to authenticate access to MIB
(Management Information Base) objects and functions
as an embedded password. The device supports a
read-only community string; authorized management
stations have read access to all the objects in the MIB
except the community strings, but do not have write
access. The device supports SNMP v1. The default
is public.
Remote Logging Enable to define a remote syslog server.
• Remote IP Address Enter the IP address of the syslog
server.
• Port Enter the port number of the syslog server. The
default is 514.
Device Authentication This option protects SSH access
to the UniFi devices. All devices in the same site share the
same SSH username and password. You can also make
changes:
• Username Enter the new username.

Settings > Wireless Networks
Configure the wireless networks for each site. You can
have up to four wireless network names or SSIDs per
WLAN group.
WLAN Group The Default WLAN group is automatically
created.
Add a New WLAN Group
click the button. Go to the Add or Edit a WLAN Group
section.
Add or Edit a WLAN Group
• Name Enter or edit a descriptive name for the WLAN
group.
Mobility
• To enable seamless roaming (Zero Handoff ),
select the checkbox.
Note: The UAP-AC, UAP-AC-Outdoor, UAP-AC-LITE,
UAP-AC-LR, UAP-AC-PRO, and UAP-AC-EDU do not
support Zero Handoff Roaming.
When you enable this option, multiple Access Points
(APs) act as an AP cluster, appearing as a single AP. The
wireless client detects only one AP, so it seamlessly
roams from AP to AP – there is no need to re-negotiate.
The APs determine which AP has the best connection
and should serve the client. They use multicasting to
communicate so they must be wired in the same Layer 2
domain.
Zero Handoff Roaming does not support wireless
uplinks and can only be used on a secured network. It
is also not meant for all scenarios. For example, if there
is too much load or interference, then Zero Handoff
Roaming may not be appropriate for your scenario.
