Hi.
I didnt think I was such a newbie until I watched this Cisco Tech Talk video
Cisco Tech Talk: Segmenting Your Switch Using Multiple VLANs
My understanding was that to keep isolation between a handful of different subnets on one of our switches, I could implement VLANs and set the required interface ports to access mode.
I dont understand the use of the LAG in this requirement or video. My only thought is that its marginally less tedious to assign interface ports to LAGs and VLANs to LAGs than assigning each interface port to the relavent VLAN.
Am I missing something fundamental or obscure ?
I look forward to any assistance.
Regards
David

Hi David,
My name is Puneet Sandel and I am from Cisco small business technical support center.
As per your query please be advised that it is not necessary to create a LAG and creating VLANs and assigning ports to the VLAN can only solve the purpose.
LAG/Etherchannel is needed in case of increasing Bandwidth between the devices(switches). Putting individual ports in LAG enhance bandwidth and is mostly needed in corporate network where there is hierarchical model (Core>>Distribution>>Access Layer switches).
In normal environment creating VLANs in a L3 switch and providing them gateway and assigning ports to the VLANs is all that is needed for communication between different subnets/networks.
