EDS-518A Series User’s Manual Featured Functions

Factory Default
The Factory Default function is included to give users a quick way of restoring EDS-518A’s
configuration settings to their factory default values. This function is available in the Console
utility (serial or Telnet), and Web Browser interface.
NOTE After activating the Factory Default function, you will need to use the default network settings to
re-establish a web-browser or Telnet connection with your EDS-518A.
Using Port Trunking
Link Aggregation allows one or more links to be aggregated together to form a Link Aggregation
Group. A MAC client can treat Link Aggregation Groups as if they were a single link.
EDS-518A’s Port Trunking feature allows devices to communicate by aggregating up to 3 trunk
groups, with a maximum of 8 ports for each group. If one of the 8 ports fails, the other seven ports
will provide back up and share the traffic automatically.
Port trunking can be used to combine up to 8 ports between two EDS-518A switches. If all ports
on both switch units are configured as 100BaseTX and they are operating in full duplex, the
potential bandwidth of the connection will be 1600 Mbps.
The Port Trunking Concept
MOXA has developed a proprietary Port Trunking protocol that provides the following benefits:
y Gives you more flexibility in setting up your network connections, since the bandwidth of a
link can be doubled, tripled, or quadrupled.
y Provides redundancy—if one link is broken, the remaining trunked ports share the traffic
within this trunk group.
y Load sharing—MAC Client traffic may be distributed across multiple links.
y To avoid broadcast storms or loops in your network while configuring a trunk, first disable or
disconnect all ports that you want to add to the trunk or remove from the trunk. After you
finish configuring the trunk, enable or re-connect the ports.
