Unable to get clients to pull DHCP addresses when using VLANs
I am unable to get some of my clients to pull DHCP addresses when associated to my APs when I have VLANs configured on the APs. Once I delete the VLANs my clients can pull IPs, but when I put the VLANs back on they can not pull DHCP addresses. I an going to attach the AP configs in order to see if anyone out there can figure out what is going on. I can not seem to resolve this issue. Thanks for all you help!
Re: Unable to get clients to pull DHCP addresses when using VLAN
I had a quick glance and everything looks OK to me. Did you remember to setup the Native VLAN on your uplink switch to match the Native VLAN on the AP? Can you reach the AP over your mgmt VLAN? Remember that DHCP won't work until after your clients are properly associated. Are your clients showing up in the AP log or under "show dot as"? What is their associated state? Where is the DHCP server and do you you have the proper helper commands setup to forward your requests on? You can also try to setup a DHCP on the AP to see if it helps.
Here's a VLAN config I use on my APs that works for me. Some parts have been snipped out.
