Necessary for the 5500G if the dhcp server is on another vlan (subnet in my case). I don't think I'd need that here, but I'll check the docs.

From: Tom Miller [mailto:[email protected]] Sent: Thursday, April 28, 2011 3:53 PM To: NT System Admin Issues Subject: Add subnet to existing vlan Hello folks, I have a private class c vlan for a user location. The site has grown, so I need more dhcp addresses. I have a 3com (now HP) 5500G switch. I added a secondary subnet to the existing vlan, so current subnet unchanged. On the dhcp server, which is on the current vlan with an IP address in the older range, I created a new DHCP scope to accommodate the new subnet. I'm not sure though the next step. How do I get clients to get a dhcp address from the new scope? Do I need to add a secondary IP, in the new scope, to the existing dhcp server? Should I do that on the existing interface, or a different interface? Or something else? I could increase the current scope to class b, but I'd prefer this method. Suggestions, those of you wiser than me on this topic?
