EdgeSwitch User Guide
Ubiquiti Networks, Inc.
Chapter 5: System Settings
- IP Address Specify the IPv6 address of the
EdgeSwitch. This IP will be used for device
management purposes. The default is an EUI-64
link-local address derived from its MAC address.
- Gateway IP Typically, this is the IPv6 address of the
host router, which provides the point of connection to
the internet. This can be a DSL modem, cable modem,
or WISP gateway router. The EdgeSwitch directs
packets to the gateway if the destination host is not
within the local network.
• Stateless Address AutoConfig Mode Disabled by
default. If enabled, the EdgeSwitch can acquire an IPv6
address through the IPv6 Neighbor Discovery Protocol
(NDP) and the use of Router Advertisement messages.
Spanning Tree Protocol
For optimal performance, there should be a single
active path between two networking devices in an
Ethernet network. Spanning Tree Protocol (STP) provides
redundant paths and prevents network loops that can
create excessive traffic and slow down performance. STP
calculates the best path for network traffic; if the best path
fails, STP recalculates and finds the next best path.
Enabled by default, STP provides redundancy without
network loops.
Version Select the version of STP to use: MSTP, STP,
or RSTP. Multiple STP (MSTP) and Rapid STP (RSTP) are
enhanced versions of STP. RSTP displays the following
states: Blocking, Learning, and Forwarding. MSTP uses RSTP
and groups VLANs together. When STP is selected, the
EdgeSwitch sends STP packets. The default is MSTP.
Max Age Specify how long the EdgeSwitch saves
a configuration message received on a port. If the
EdgeSwitch does not hear any new configuration
messages after the Max Age time interval, then the
EdgeSwitch adapts and starts to reconfigure. The default is
20 seconds.
Hello Time Specify the time interval between
configuration messages transmitted by the EdgeSwitch to
other switches. The default is 2 seconds.
Forward Delay Specify how long the listening and
learning states last before the EdgeSwitch forwards traffic.
The default is 15 seconds.
Priority STP uses priority values to select a switch as the
root switch of the spanning tree. Specify the Priority value
of the EdgeSwitch. The default is 32768.
Services
Configure the following services: UNMS, Remote System
Log, SSH Server, Telnet Server, Web Server, and SNTP Client.
UNMS
Enabled/Disabled Disabled by default. Enabling this
option activates UNMS access to the device.
• UNMS Key Enter the UNMS key, which helps to secure
communication between the device andUNMS. For
more information, go to: ubnt.link/UNMS‑Key
Remote System Log
Every logged message contains at least a system time and
host name. Usually a specific service name that generates
the system event is also specified within the message.
Messages from different services have different contexts
and different levels of detail. Usually error, warning, or
informational system service messages are reported;
however, more detailed debug level messages can also
be reported. The more detailed the system messages
reported, the greater the volume of log messages
generated.
Enabled/Disabled Disabled by default. If enabled, system
log messages are sent to a remote server.
• Remote Server Hostname Enter the hostname of the
remote server that receives syslog messages. Properly
configure the remote host to receive syslog protocol
messages.
