We have the following current setup.
1 flat network
Need 12 specific ports in VLAN 15 and only internet access on LAN
IP range 10.33.0.0/21
DHCP - Windows server 10.33.1.60
POOL - 10.33.6.1-10.33.6.254
DNS - 10.33.1.60
GW - 10.33.0.254
Cisco 4507 - 10.33.0.25
Have setup VLAN 15 and assign a port to it, when I do I lose network connectivity. Tried to build another DHCP pool on the 4507, but when I add the network 10.33.7.0 255.255.248.0, it puts the entire subnet 10.33.0.0, which is already on Windows server.
What I thought would happen is it would add just the 10.33.7.0 subnet and I could assign the ports to it and they can use this pool and existing gateway.
What am I not understanding or missing or other options?
