Hi all,
we have 5x Dell S3048 Switches, combined to a cluster. I created our new VLANs / Subnets and their DHCP-Scopes where needed.
To explain the main problem, here are 2 of them:
- Normal User-VLAN/Subnet: 172.16.103.0/24 (DHCP-Scope from 11.-.230)
- Finance User-VLAN/Subnet: 172.16.112.0/24 (DHCP-Scope from 11.-30.)
I configured two ports untagged. One in vlan 103, the other one with vlan 112. DHCP-Server is configured in both vlans.
Notebook #1 is plugged in Port 1, gets IP 172.16.103.11. Plug it out, delete his DHCP-Lease, plug it into Port 2 and then it gets again the same IP with a fresh lease. After it got the false IP, the notebook is not able to communicate anymore.
Notebook #2, plugged in vlan 112, gets IP 112.11, plug out, delete lease in dhcp, plugging in vlan 103, gets a fresh lease from previous vlan 103.
i have no idea why this happens :(
I hope someone can help me out. Thanks in advance
