EDS-P510 Series Featured Functions
3-15
The Factory Default function is included to give users a quick way of restoring EDS-P510’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-P510.
Using Port Trunking
Link aggregation involves grouping links into a link aggregation group. A MAC client can treat link aggregation
groups as if they were a single link.
The EDS-P510’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 automatically provide
backup and share the traffic.
Port trunking can be used to combine up to 8 ports between two EDS-P510 switches. If all ports on both
switches 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:
More flexibility in setting up your network connections since the bandwidth of a link can be doubled, tripled, or
quadrupled.
• Redundancy—if one link is broken, the remaining trunked ports share the traffic within this trunk group.
• Load sharing—MAC client traffic can 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 switch units are configured as 100BaseTX and they are operating in full duplex mode, the
potential bandwidth of the connection will be up to 1.6 Gbps. This means that users can double, triple, or
quadruple the bandwidth of the connection by port trunking between two EDS series switches.
Each EDS-P510 can use a maximum of 3 port trunking groups. When you activate port trunking, certain
settings on each port will be reset to factory default values or disabled:
• Communication redundancy will be reset
• 802.1Q VLAN will be reset
• Multicast Filtering will be reset
• Port Lock will be reset and disabled.
• Set Device IP will be reset
• Mirror will be reset
After port trunking has been activated, you can configure these items again for each trunking ports.
