IKS-6726 Featured Functions
3-13
Factory Default
This function provides users with a quick way of restoring the IKS-6726’s configuration to factory defaults. This
function is available in the serial, Telnet, and web consoles.
NOTE After restoring the factory default configuration, you will need to use the default network settings to
re-establish the web or Telnet console connection with the IKS-6726.
Using Port Trunking
Link aggregation involves grouping links to into a link aggregation group. A MAC client can treat link
aggregation groups as if they were a single link.
The IKS-6726’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 IKS-6726 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:
• 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 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 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 PT series switches.
Each IKS-6726 can set 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 may configure these items again for each trunking ports.
