Basic query on VLANS and IPHELPERS.

Hi All,

Have a layer 3 switch with VLAN 100 on it (for example) which has an IPHELPER pointing to the firewall for DHCP. Plugging a device into a port untagged on VLAN 100 gives me a DHCP address and all is happy with the world!

I want to connect a L2 switch to the L3 switch to add some more ports etc.

Will a device plugged into an access port in VLAN 100 on the L2 switch still get DHCP address by the fact the L3 switch has the IPHELPER on it? Or does the IPHELPER need to also be present on the switch the device is plugged into?
