Quick Settings
The Quick Settings section includes the most common settings required by administrators to maintain and
control a Moxa PowerTrans Series switch.
System Time
The Moxa switch has a time calibration function based on information from an NTP server or user specified time
and date. Functions such as automatic warning emails can therefore include time and date stamp.
NOTE
The Moxa switch does not have a real time clock. The user must update the Current Time and Current Date
to set the initial time for the Moxa switch after each reboot, especially when there is no NTP server on the LAN
or Internet connection.

Accessible IP List
The Moxa switch uses an IP address-based filtering method to control access.
You may add or remove IP addresses to limit access to the Moxa switch. When the accessible IP list is enabled,
only addresses on the list will be allowed access to the Moxa switch. Each IP address and netmask entry can be
tailored for different situations:
• Grant access to one host with a specific IP address
For example, enter IP address 192.168.1.1 with netmask 255.255.255.255 to allow access to 192.168.1.1
only.
• Grant access to any host on a specific subnetwork
For example, enter IP address 192.168.1.0 with netmask 255.255.255.0 to allow access to all IPs on the
subnet defined by this IP address/subnet mask combination.
• Grant access to all hosts
Make sure the accessible IP list is not enabled. Remove the checkmark from Enable the accessible IP
list.
The following table shows additional configuration examples:

GARP Timer Parameters
Generic Attribute Registration Protocol (GARP) was defined by the IEEE 802.1 working group to provide a
generic framework. GARP defines the architecture, rules of operation, state machines, and variables for the
registration and de-registration of attribute values.
The GARP Timer parameters are exchanged by creating the applications via GVRP (GARP VLAN Registration
Protocol) to set the attributes of Timer.
Note that you need to set the same GARP timer values on all Layer 2 switches to ensure that the system works
successfully.

IEEE 1588 PTP
The following information is taken from the NIST website at http: //ieee1588.nist.gov/intro.htm:
“Time measurement can be accomplished using the IEEE Standard for a Precision Clock Synchronization
Protocol for Networked Measurement and Control Systems (IEEE 1588-2008) to synchronize real-time clocks
incorporated within each component of the electrical power system for power automation applications.
IEEE 1588, which was published in November 2002, expands the performance capabilities of Ethernet networks
to control systems that operate over a communication network. In recent years an increasing number of
electrical power systems have been using a more distributed architecture with network technologies that have
less stringent timing specifications. IEEE 1588 generates a master-slave relationship between the clocks, and
enforces the specific timing requirements in such power systems. All devices ultimately get their time from a
clock known as the grandmaster clock. In its basic form, the protocol is intended to be administration free.”
How does an Ethernet switch affect 1588 synchronization?
The following content is taken from the NIST website at http: //ieee1588.nist.gov/switch.htm:
“An Ethernet switch potentially introduces multi-microsecond fluctuations in the latency between the 1588
grandmaster clock and a 1588 slave clock. Uncorrected these fluctuations will cause synchronization errors.
The magnitude of these fluctuations depends on the design of the Ethernet switch and the details of the
communication traffic. Experiments with prototype implementations of IEEE 1588 indicate that with suitable
care the effect of these fluctuations can be successfully managed. For example, use of appropriate statistics in
the 1588 devices to recognized significant fluctuations and use suitable averaging techniques in the algorithms
controlling the correction of the local 1588 clock will be the good design means to achieve the highest time
accuracy.”
