VLAN DHCP not working was created by agility
Hi all,
I've got a 2960 connected to a Netgear GS724 connected to a Linksys AP. I've created a new SSID with VLAN ID 40 to segment guest Wi-Fi access to our network, and configured this on the switch and the Draytek too, but the Draytek doesn't seem to issue an IP address. I can see the device that has joined the public Wi-Fi, and I can see it in the MAC table on the switch, so I'm sure the problem is at the Draytek. What's odd is that I've already got another VLAN working in a similar way for our VOIP phones, albeit the phones seem to take a minute or so to pickup an IP address from the Draytek. Here's the setup in more detail:
2960 Port 2 has three VLANs associated with it:
VLAN ID 11 - DATA LAN - 192.168.2.x - no DHCP - Member & Untag
VLAN ID 50 - VOICE LAN - 192.168.50.x - DHCP - Member
VLAN ID 40 - GUEST WIFI - 192.168.40.x -DHCP - Member
The Netgear has the corresponding ports set as trunks to accept traffic on all three VLANs
Any pointers where I might be going wrong?
