EDS-516A Series User’s Manual Featured Functions
3-13
Port trunking can be used to combine up to 8 ports between two EDS-516A 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.
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 1.6 Gbps on the EDS-516A. This means
that users can connect one EDS-516A to another EDS-516A by Port Trunking to double, triple, or
quadruple the bandwidth of the connection.
When configuring Port Trunking, note that:
Each EDS-516A can set a maximum of 2 Port Trunking groups (Trk1/Trk2, 2 trunk groups for
10/100M ports)
When you activate Port Trunking settings, some advanced functions that you setup with the
original ports will either be set to factory default values, or disabled:
y Communication Redundancy will be set to the factory default
y Traffic Prioritization will be set to the factory default
y Port-based VLAN or 802.1Q VLAN will be set to the factory default
y Multicast Filtering will be set to the factory default
y Rate Limiting will be set to the factory default
y Port Access Control will be set to the factory default
y Email and Relay Warning will be set to the factory default
y Set Device IP will be set to the factory default
y Mirror Port will be set to the factory default
You can setup these features again on your Trunking Port.
