OK so here's what I am trying to accomplish with 3 Cisco SG500-52 switches. I have created 4 VLAN's on one SG500 that I'm calling my core switch and it's set to routing mode. My VLAN's are as follows 400 (Infrastructure ESXI hosts, firewall, etc), 401 (VoIP), 402 (Users), and 403 (Wireless). I have interfaces configured and everything is routing without issue for me across my subnets and remote access communities across 3 offices.
Where I am unsure is on the SG500 I have set as a L2 switch and my ESXi host are connected (I do have 10 ports on an isolated VLAN for iSCSI traffic) is do I need to create VLAN 400 and mark those as untagged ports? Then should I use 1-2 ports and set them as trunked ports and tag them to 400 to my core switch?
If so on the core switch do I create trunk ports and tag them for the VLAN's on this switch that would access the L2 switch? Is that also the case for the other SG500 that I have that are all devices for VLAN 402?
