Home Network: EtherChannel, VLANs, and STP

Home Network: EtherChannel, VLANs, and STP



  • Configure EtherChannel
  • Verify STP
  • Verify EtherChannel/Port-Channels

Going on from what I configured yesterday I'm now going to configure EtherChannel between my switches. Which I hope will give each VLAN two trunk links each to the root switch, giving each VLAN 200Mbps to the root switch.

I've already configured all of the other switches. So this is my final switch to configure. The links will drop when the commands are entered, but will re-established. List of the commands I used can be found here.

Configure EtherChannel

You may see some STP messages like the one below;

This will resolve itself once I've finished entering the rest of the port-channel commands for those interfaces;

Verify STP

Verify EtherChannel

I did spot an error where i assigned interface 21 and 22 to port-channel 6 I corrected this with the following command;

So now the summary does not list 4 interfaces for port-channel 6
