Firstly, thanks for reading.
I'm doing some test configuration to move our network away from a flat network to one that uses VLANs. I've got a N3048 setup with a test DHCP server and I've created two subnets and associated VLANS - 192.168.28.1 (VLAN 28) and 192.168.32.1 (VLAN 32). Our regular network uses the 10.10.0.0 range, so my test DHCP server has an address of 10.10.0.2 and also issues addresses in the 10.10.0.0 range.
I've got the routing setup on the switch and everything seems to be working fine. If a plug a test PC into a VLAN access port I get a DHCP address in the correct range and I can ping devices on other VLANs.
The IP address of the default VLAN is in the 10.10.0.0 range and devices plugged into ports that are not configured for the other VLANs get a DHCP address in the 10.10.0.0 range. This is great, as I want to slowly introduce VLANs to my network.
However, I'm having trouble getting this to work when I plug another switch into my N3048. The majority of switches on our network are non-Dell; mainly D-Link and Netgear. So, I've setup a test Netgear switch and configured it as follows:
Port 1 - Untagged VLAN 28
Port 2 - Untagged VLAN 32
Port 24 - Tagged VLAN 28 and 32
I've then configured a Trunk port on the N3048 and plugged port 24 from the Netgear into it.
However, with a PC plugged into any port on the Netgear switch I always get a DHCP address in the 10.10.0.0 range, rather than one for the VLAN? I've tried setting the port on the N3048 as a General port, but that doesn't work either. It seems that the default VLAN 1 is alway dominant.
Any advice on what I do now?
Many thanks for reading this far, and hopefully replying.
