DHCP Relay in a 2960-S

netguyz08

Level 1

Windows Server 2008 R2 has two DHCP scopes 192.168.1.x (for data) and 192.168.2.x (for VOIP). The Catalyst 2960-S has Vlan1 for the Data VLAN and Vlan 2 for the VOIP network. How do I setup DHCP relay for Vlan2 to get their IPs from the scope on the Windows server?

Used to doing ip helper-address x.x.x.x in other Catalyst switches, but not available here.

Hello

The router/l3 switch which connects to the L2 switch can be the dhcp relay - On the svi for vlan 2 apply the relay ip address of the dhcp server using ip helper address.

router/l3 switch

int vlan xx

ip helper-address xxxx (dhcp server ip address )

On a side note - if applicable make sure or verify the dhcp scopes are active and authroised on the wintel server?
