I have attempted to search this problem but I don't really know how to explain it properly (possibly a sign I've taken on more project than I can handle).
Anyway I am currently working on chopping our giant one subnet network into multiple subnets. I'm using VLANs to achieve this.
Each geographically different site will be its own subnet / VLAN.
I've got everything working properly on my test subnet in my office and it's going quite well.
However I'm not quite sure what the best practice is for the VLAN configuration on the switches. In particular the switches at each site (subnet) that service the devices / computers.
Should I be tagging / trunking the VLANs through to the switches that service the users and then untagging the VLAN on each port (other than the trunk port) on that switch.
Or should I be untagging the VLAN on the upstream port (i.e. the fibre port that goes off to the subnet / site) and then just using the native VLAN on the switches at the sites / subnets?
Any help is appreciated. I'm sure I've broken at least 20 obscure Stack Exchange rules with this post, so apologies in advance.
