Just wanted to follow up. Switching the mode to L2 from L3 across all switches made this work. Apparently being in L3 caused the switches to be unable to communicate across the trunk the vlan tags. All is now working properly. Again, thanks!

I'll be doing the layer 2 switch. Unsure as to why they were on layer 3 in the first place --- before my time I suppose. Thanks Eric and Alex for your suggestions.

Thanks guys for the information, and the heads up about the config. I'll make a backup config of the settings but if I restore the config I'll be back on level 3 again. I suppose it won't be all that difficult to just redo the settings by hand and I'll keep the config handy if anything goes wrong.

Will changing an SG300 switch from Layer 3 to Layer 2 cause any significant user downtime, or any at all? I have two 52-port SG300's and two 20-port SG300's to make this change to.

Eric, do you think that our switches all being on layer 3 would cause this problem? They are all on layer 3. I read an IBM article which stated: "A trunk connection is a link that carries VLAN information between VLAN-aware Layer 2 devices." http://publib.boulder.ibm.com/infocenter/tivihelp/v20r1/index.jsp?topic=%2Fcom.ibm.tivoli.tpm.net.doc%2Fnetwork%2Fcnet_trunking.html

All APs are exactly the same aside from hostname, device name, and IP address. Im unsure how I would be able to configure a PC for vlan 2. I haven't tried it. A PC directly to the firewall does get internet. Corporate SSID works perfectly on all access points.

Hi Eric, thanks for the reply. The primary switch which is connected to the firewall is a SG300-52 Port Managed Switch. It's in our server room and contains the port which is vlan'd to the firewall. This switch has the access point which works properly as a guest network. All of the secondary switches are SG300-20 Port Managed Switches. There are two of them which have access points connected to them. One has a single access point connected to it, the other has two access points connected to it. All of these access point ports are configured as 1UP 2T because all of our access points also host the corporate ssid which is on 1. The guest is on 2. These SG300-20 switches have direct connections to ports 41,42,44 on the primary switch. These are also tagged 1UP 2T. The ports on these switches which run to the primary switch are taged 1UP 2T as well. Basically every port involved in the process of getting back to the primary switch from the access point has been VLAN'd to include 2 and leaving 1 as untagged. The only port which is 2UP is the firewall port on the primary switch.

Thanks for the response. The guest VLAN is present on all the devices. VLAN 2 is set to tagged on all related ports and access points. VLAN 2 is tied to the Guest SSID. The Guest wireless works perfectly fine on the access point which is connected to the switch which contains the port running to the firewall, port 50. However, when I switch to an access point that is on a secondary switch I no longer reach the firewall on the guest ssid. Corporate SSID still works perfectly fine on all switches. This leads me to believe that there is an error in my configuration in relation to getting the VLAN information to travel between the switches. The ports which connect to the primary switch on all secondary switches are trunk ports. How is VLAN information supposed to travel inbetween switches? As of now I have the VLAN information configured on the ports which connect the secondary switches to the primary switches and those access points are not working.

Getting no reply is disheartening, but I'll continue with my question... I've managed to get this working on the switch which is directly connected to the firewall. However, internet access is not working from the other switches which are wired into the primary switch. What I've done is this: Port 50 on the primary switch --- 2UP Port 36 on the primary switch (which connects to the access point which is working) --- 1UP 2T Port 41/42/44 on the primary switch (which connect to the other switches) --- 1UP 2T On the secondary switches, the ports which lead to the primary switch --- 1UP 2T On the secondary switches, the ports which connect to the access points --- 1UP 2T. Any wireless connection on a guest network ssid which is hosted on a secondary switch is not reaching the firewall. This leads me to believe there is an error in my configuration of the VLAN. How do I need to set this up in order to have the secondary switches pass the VLAN information to the primary switch? These are all SG300's.

Hi there everyone, Looking to have an issue of mine resolved. Currently I am running 4x WAP4410N access points configured with a single corporate ssid with WPA2 Enterprise authentication which is pointing to a network access protection server. What I am trying to do is add a second ssid to all of my access points which is for guests only and cannot connect to corporate resources/devices. I believe I have to VLAN in order for this to work properly. The four access points are connected in various parts of the building and are wired into different SG300 switches. One port on a SG300-52 in my server room is wired into a port on my firewall which I'd like to use for DHCP. What will I need to do in order to get this functioning properly? At the moment my test guest network isn't even giving out an IP address to devices, which I believe is related to the VLAN. I'm not sure what ports I need to leave tagged/untagged, how to configure the vlan across the multiple switches, etc. Any help would be appreciated. It was suggested to me that I could use seperate access points entirely for guest access, but I'd like to keep the amount of access points down to the minimum required.
