EtherChannels Cisco offer another method to scale link bandwidth by Aggregation Parallel link turn the ether channel technology. An EtherChannel is a way of combining several physical links between switches into one logical connection.  Normally, Spanning Tree blocks redundant links; EtherChannels get around that and enable load balancing across those links.  Traffic is balanced between the channel links on the basis of such things as source or destination MAC address or IP address.  The EtherChannel load-balancing method is configured at global configuration mode.  A logical interface—called the Port Channel interface—is created. Configuration can be applied to both the logical and physical interfaces. Terms for EtherChannel Configuration Can consist up to maximum 8 physical port. All ports must be the same speed and duplex. All ports in the bundle should be enabled. None of the bundle ports can be a SPAN port. Interfaces in the channel do not have to be physicall

VLANs divide the network in to smaller broadcast domains but also prohibit communication between domains. To enable communication, we use InterVLAN Routing. In InterVLAN routing, use two or more VLAN connectivity. InterVLAN routing also called Router on Stick Method.
