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-600.
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.
The EDS-600’s Port Trunking feature allows devices to communicate by aggregating up to 4 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-600 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 1.6 Gbps.
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.
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 up to 800 Mbps on the EDS-600. This means
that users can connect one EDS to another EDS by Port Trunking to double, triple, or quadruple
the bandwidth of the connection.
When configuring Port Trunking, note that Each EDS-600 can set a maximum of 4 Port Trunking
groups (designated Trk1, Trk2, Trk3, Trk4).
