Ruckus DHCP Relay != Cisco/HP DHCP Relay
I'm working on configuring WLANs with vlan tagging. My understanding of DHCP relay from my networking background is a way of relaying DHCP request between different vlans. DHCP relay in the Ruckus world is a way of broadcast traffic management. Can someone correct me if I'm wrong?
If I'm right, I'm running stuck. I've trolled the forums for a while trying to find similar situations.
DHCP server on vlan 10 and it has two scopes: main network: 10.0.0.0/16 (for vlan 10) and guest network: 10.1.0.0/16 (for vlan 20). I have an L3 switch that does the DHCP relay (using ip helper-address). Router is configured properly too.
I connect a laptop via wired connection to a port with a vlan assignment of 20 The laptop gets an IP address in the 10.1.0.0/16 subnet and all is well.
I disconnect the wired and connect the wireless to a vlan 20 tagged WLAN and it doesn't get an IP address at all. Wireshark shows no DHCP responses coming back.
I configured the WLAN with Ruckus' DHCP relay per documentation and I get an address back in the 10.0.0.0/16 scope.
What doesn't make sense to me is if I have a WLAN with vlan tagging, shouldn't that be the same as plugging in a wired connection to a vlan tagged port?
