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-510A 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 800 Mbps.

The Port Trunking Concept

Moxa has developed a proprietary Port Trunking protocol that provides the following benefits:

yGives you more flexibility in setting up your network connections, since the bandwidth of a link can be doubled, tripled, or quadrupled.

yProvides redundancy—if one link is broken, the remaining trunked ports share the traffic within this trunk group.

yLoad sharing—MAC Client traffic may be distributed across multiple links.

yTo 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-510A. 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-510A can set a maximum of 4 Port Trunking groups (designated Trk1, Trk2, Trk3, Trk4)

When you activate Port Trunking settings, some advanced functions that you set up with the original ports will either be set to factory default values, or disabled:

yCommunication Redundancy will be set to the factory default

yTraffic Prioritization will be set to the factory default

yPort-based VLAN or 802.1Q VLAN will be set to the factory default

yMulticast Filtering will be set to the factory default

yRate Limiting will be set to the factory default

yPort Access Control will be set to the factory default

yEmail and Relay Warning will be set to the factory default

ySet Device IP will be set to the factory default

yMirror Port will be set to the factory default

You can setup these features again on your Trunking Port.
