Introduction to Managed Ethernet Switches
Moxa’s managed Ethernet switches (not including the EDS-400A)
support IEEE 802.1X (Port-based Network Access Control) to restrict
port access to authorized users only. Authentication is done using the
local user database or an external RADIUS (Remote Authentication
Dial In User Service) server.

IEEE 802.3ad (LACP, Link Aggregation Control Protocol) provides
flexible network connections and a redundant path for critical devices.
For example, the EDS-G509 and EDS-500A allow users to set up a
wider communication path by aggregating a trunk group. A maximum
of eight ports can be assigned to one trunk group to optimize your
network connection and redundant paths. When selected ports are
grouped for trunking, LACP will exchange information to determine
whether or not the ports selected in a group can be trunked together.
IPv6 is the next generation protocol for Internet networking. Since
IPv4 addresses will be completely used up in the near future, support
for IPv6 (128-bit IP addresses) is important to secure the future of
your network. Moxa’s managed Ethernet switches support IPv6 to
offer better addressing and security for large networks, and to protect
your future investments.
IEEE 1588, also known as Precision Time Protocol (PTP), is designed
to synchronize real-time clocks located at the nodes of a distributed
system that communicates over a network. Moxa’s managed Ethernet
switches (not including the EDS-400A) are well suited for applications,
such as motion control, that require distributed clocks to be
synchronized with high accuracy.

HTTPS/SSH
In order to protect data from being intercepted, Moxa’s managed
Ethernet switches (not including the EDS-400A) support the HTTPS
and SSH protocols for transferring data over the Internet in an
encrypted form. If you are changing the configuration of an Ethernet
switch online, be sure to use HTTPS and SSH to keep your data
secure.
