Hi, yes in Cisco there is a technology that they call fast-Etherchannel or Gigabit-Etherchannel, if you only put these 2 ports in parallel with this parameter disable, you will create a loop. Then you need to enable firts a group of FastEther-channel, and then add to this group the ports that create the logical tunnel, and that will be part of this group. You can group until 8 ports, in this way you can create a throughout of 1.6 Gpbs duplex.
if you plug an additional link in it will cause a loop, spanning-tree will find this loop and will disable one of the ports. If the other port went down the second port will renable itself as a resillient link. You may have configured portfast if any stations are directly connected to the switch ports I advise that you ensure this is not enabled on the ports you wish to link. Next I would configure the ports to 100 full duplex, on a dual utp link this should give you a throughput of 400mbps. If you have no experience of the command line follow the guide to use the web browser...

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
