Implementing Vlans a few questions

[Todd Willoughby]

Hey folks, Im getting in a new 3560X (WS-C3560X-48PF-S) switch in very shortly and Im going to be taking my single flat network and implementing Vlans (about 7 in total) Im going to be using this new 3560X switch to do the inter-vlan routing. My question is, I have a DHCP and DNS server that is going to be in the same VLAN as my users and other internal clients. Is there a way to have this server fullfill DHCP and DNS request for other VLANS that are going to be implemented on the network?

yes, you just need to add this command to the SVIs for your other vlans.  So lets say the DHCP is in vlan 2, and you have vlan 3, 4, and 5, etc....  Under the the svi interfaces for vlan 3, 4, and 5 add this command:

ip helper-address xx.xx.xx.xx 
where xx.xx.xx.xx is the ip address of the DHCP server
