N2048P VLAN Spanning and Mirroring
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 ?

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 Daniel,
Thanks for the reply, I am using IP Helper on this switch core as its stack is configured in L3, the DHCP server resides in the default VLAN (1) at the moment and it seems to be fine on that VLAN, but wont issue an IP to any of the other VLANs outside of the core switch from the DHCP server, which also resides on VLAN1 (I have the uplink ports all set as General with the voice VLAN set as tagged, all other VLANs are untagged on the general port), the VLANs can be pinged fine from the remote switches, but wont issue an IP with DHCP to a VLAN, only on the core switch, I also have tried the DHCP L2Relay feature and that hasn't worked for this issue (all other switching at our site is L2 with the core operating as L3)
Thanks for the RSPAN Guide, I have been struggling with that and the vlan change.
