I have 3 48 ports SD Switches linked by means of SPF+ and fiber. We want to define VLANs according to their use:
VLAN 10 for Data Services (PC´s & Servers)
VLAN 20 for Access Points (No voice required)
VLAN 30 for Voice Services (IP Phones and IP PBX)
Right now switches are working but I see that PCs and Servers are assigned to VLAN1 which is defined by default. We have identified that if we configure LAN ports specifing ALL vlans, everything works correctly but if we speficy the proper VLAN (i.e. VLAN 20 for access points) we lost monitoring of it.
Any basic guidelines about how to define such VLANs? How to avoid sending data over VLAN 1 ? Any experiences with such behave
