EDS-508A/505A Series User’s Manual
Featured Functions
3-19
Factory Default
The Factory Default function is included to give users a quick way of restoring the EDS’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.
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-508A/505A’s Port Trunking feature allows devices to communicate by aggregating up to 2
trunk groups on the EDS-505A and 4 trunk groups on the EDS-508A. If one of the ports fails, the
other ports in the same trunk group will provide back up and share the traffic automatically.
The Port Trunking Concept
Moxa has developed a proprietary Port Trunking protocol that provides the following benefits:
Gives you more flexibility in setting up your network connections, since the bandwidth of a link
can be doubled, tripled, or quadrupled.
Provides redundancy
—
if one link is broken, the remaining trunked ports share the traffic within
this trunk group.
Load sharing
—
MAC Client traffic may be distributed across multiple links.
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.
If all ports on both switches are configured as 100BASE-TX and they are operating in full duplex,
the potential bandwidth of the connection will be up to 1 Gbps on an EDS-505A switch and 1.6
Gbps on an EDS-508A switch. This means that users can connect one EDS to another EDS by port
trunking to double, triple, or quadruple the bandwidth of the connection.
