Thanks Daniel for your help so far, I managed to fix it, I realised that the port for the DC wasn't trunked, as soon as I put that live  I have then sorted out that issue and the VLAN is firing away without any issues now.
Hello all,. I have experience of Cisco kit until recently, I have a network with 2 x N2048P stacked as the core switch, this has replaced a pair of Cisco SG500X switches on our network and on the whole its been so far so good, we have a couple of issues though which I think we may have already answered on the forums, but I would like to give it a try if possible, 1. Were finding that DHCP for our other VLANs wont span across the switching as were currently using VLAN1 for servers (this is being arranged to be changed, but its not simple in a live network and is currently in planning) 2. Remote Port Mirroring - We have a security appliance that we need to have with port mirroring on, the vendor is stating that the device isn't seeing on the cisco it was a case of picking a destination port and pointing the VLANs to it, which obviously isn't the case with the N2048P switch, are there any guides or clues as to how I would do that sort of VLAN mirroring on these switches ? or is it a feature that's not supported ? 3. Changing the default VLAN - is there a universal command to achieve this on the Dell unit ?
