fail to get ipv4 address after change to new catalyst 6509-E with SUP2T

[jackson.ku]

Hi,

The core switch of our company is Catalyst 6509 with SUP2. Last week we change to new Catalyst 6509-E with SUP2T. The configuration of new core switch are almost same with old switch, we have not enable ipv6 routing. But after we change core switch to new core switch, some WIN7 client fail to get IP address from DHCP server. These WIN7 client enable both ipv6 & ipv4 and both configure automatic to get IP address. After disable ipv6 protocol at WIN7 client, then these client can get ipv4 IP address from DHCP server.... Please help to mention me how to resolve this problem if not disable ipv6 at WIN7 client?

Best Regards,

Hi,

What version and what feature set of IOS are you running on Sup-2T?

Can you post "show run" when the clients are not able to get IPs?
