Hi,
I have an access HP switch which is connected to an Cisco Backbone switch. The dhcp server and the clients are in different vlans.
We just enabled the dhcp-snooping on our HP switch but next day some of our clients could'nt get ip address. When I checked with my pc I also couldnt get ip. But when I check the binding table I see some clients could get ip address. So what can be the problem? Also I do not see any drops in dhcp-snooping stats. As soon as I disable dhcp-snooping I can get an ip.
I also wrote this problem to HP forums but from there I could not get any response.
Thanks
