Hi,
I have a 3750G-E switch. When I tried configuring a DHCP server within the switch, it was not giving out ip addresses on all the ports. So, I tried configuring the ports to use VLAN 1, and it is now working.
My question is that, is there any way that I can create multiple DHCP server in a 3750G switch to cater to multiple VLANs (vlan 10, 20, 30, etc) other than vlan 1.
Thanks,
Ninoy

Yes you can create multiple DHCP ranges that correspond to multiple VLANs. You would create multiple DHCP address pools with subnets that correspond to the subnet addresses of the VLAN interfaces. Then when a DHCP request is received the switch looks at the VLAN interface it was received on and assigns an address from the pool that corresponds to that subnet.
