TN-5516/5518 Series Featured Functions
3-15
Restart
This function provides users with a quick way to restart the system.
Factory Default
This function provides users with a quick way of restoring the TN-5500’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 TN-5500.
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 TN-5500’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 TN-5500 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.
