Guest IMRAN BHATTI Posted January 22, 2008 Posted January 22, 2008 Hi All, I am in trouble due to DHCP Superscope. I am planing to using the 6 VLANS for our new network and cat 4500 as a Layer 3 switch Our VLAN routing will be done by L3 switch and on the Vlan i mentions the Ip-Helper address. I set up the test scenerio to simulate our new scenerio. now i am coming to my problem When i use superscope , DHCP diserver did not give the appropriate VLAN Ip address to the clients ( Although i mentioned the Ip-Helper address in Switch). for example pcs on vlan3 get the ip address from Vlan 4 and hence cannot communicate with any one. If i removed the Superscope then may be problem resolved as i read from many posts. Could anyone will help me to design the trouble free DHCP server. One more question is if i removed the superscope of the DHCP server ( Already in production ( different then Above)) what will be the impact on the client leases ?? Thanks very much for your help and reading my problem.
Guest Ryan Hanisco Posted January 23, 2008 Posted January 23, 2008 RE: MS DHCP ( IP-HELPER) and Superscope Hello Imran, Can you give us an example of the subnets in VLSM and the scopes. Remember that you'll need to have the subnets match the masking on the scops to have it appropriately mapped. You'll need to gie us more detail to help you troubleshoot.
