Vlan isn't working correctly
Hi,
I've set up switch GS724T like this :
g1-g8 (vlan10)
g9-g18 (vlan20)
g19-g23 (vlan30)
g24 MIRROR
My problem is when I connect my computer on port g2 I received packet from dhcp on vlan 10 ( Good news ) BUT
if I connect on port g7 or g8, I don't received any offer from my dhcp (vlan 10)..
I looked up with Wireshark with a port mirroring, and simulate a new connection on g7. I observed that equipment connected to g7 make a request to broadcast and after that DHCP's server on vlan 20 try to offer him an address. But of course he can't reach the equipment..
So i've got two questions :
How the broadcast can pass through the vlan10 ?
How DHCP's server (on vlan 20) can receive this request from vlan 10 ?
What's wrong ?
The only settings that I've made are vlans, g1-g8 (U) g9-g18(U) g19-g23(U)
Thanks in advance,
Regards,
Hi hugo_jove,
Welcome to our community!
About your settings and configuration seems that you haven't change the PVID yet on the ports so the incoming traffic is still going to VLAN 1 and that will explain why you see the broadcast on the wireshark.
Could you test the following configuration :
g1-g8 (vlan10) -- Change PVID to 10
g9-g18 (vlan20) --- Change PVID to 20
g19-g23 (vlan30) --- Change PVID to 30
Let us know if it works for you!
