I'm trying to setup a 48 ports gigabit switch (netgear GS748T).
My goal is to split the 48 ports to 3 vlans :
- VLAN10 ports 2-20
- VLAN20 ports 21-30
- VLAN30 ports 31-46
What i did is :
- On VLAN1, TAG port 1, UNTAG every other ports
- On VLAN10, TAG PORTS 2-20, UNTAG every other ports
- On VLAN20, TAG PORTS 21-30, UNTAG every other ports
- On VLAN30, TAG PORTS 31-46, UNTAG every other ports
I didn't touch the PVID configuration page; don't know what this is.
Now, if i plug a cable to port 5, i can ping VLAN20 and VLAN30; same for VLAN20 i can ping VLAN10 and VLAN30.
What am I doing wrong here ? I'm quite new to VLANs ...
edit: VLAN10 is WAN (connected to firewall interface x0, public subnet/26) VLAN20 is MGMT (connected to firewall interface x4, 10.0.0.x/24)
Whenever i plug from firewall to vlan20 i see all ports of the switch go crazy and i have packet loss when pinging switch or accessing his web ui.
