Log into your managed switch with the administrative username and password.
Click Configure on the left hand side. Choose Port Settings from the list.
Select all ports to be used for PXE boot. Click Modify. Enable Port Fast. Save. Close open windows.
With Configure still selected, choose IGMP Snooping. Click the “Multicast Router Ports” tab.
Click Create, enter the number of the vlan you wish to apply changes to, select all ports to enable multicast on (Select All click Add) click the apply button, settings may take a few minutes to take affect.

{ORIGINAL POST}
Hey all,I’m touching base here and hoping to find some information.
Normally I work HP Pro-Curve equipment, but one of my school buildings had a new addition added to it and along with it, a whole new switch and network was added to the building that was purchased by the installation contract (So we got the equipment that the normally set up), installed by the contractors, and managed by the contractors. Now that they are gone, I have no one to help me to square away the new issues that are arising.
I am looking for someone versed in these managed switches that can help me to get the new addition talking to the rest of my network properly. Currently DHCP, and Novell are working. Each machine is doled IP addresses from my DHCP server as expected, the units can log in and talk to my sever, tree, context all that good stuff. I can browse my NDS, but my fog server is not passing the PXE boot information through the new switches. I use the dchpmasq service to normally allow my units to boot via pxe, and the rest of the building is still working as expected THANK GOD, but the new addition is giving me fits!
I can unplug my new Cisco managed switch and replace it with a “hub” of sorts and I can still see my pxe boot information as expected so I am thinking that there is maybe an IP helper or something along the lines that I need to update/add.
So anyone with expertise or suggestions, I am open

What is the model of the switch?
I don’t, typically, deal with the network configuration, but I know how if I ever needed to. I may not have hands on, but if you don’t know me by now, I can be pretty resourceful.

Though I’m not very familiar with programming switches, I would think that you need to setup the next-server options to point at your fog server. ip-helper, to my knowledge, would be to help point the switch at the DHCP server, which you state is already working. Now you’re just needing it to look at the PXE server, which for my understanding would be simply (if I understand proxyDHCP at all – I probably don’t) next server to point at the fog server IP.
Don’t listen to me though, I really don’t know much about all of this and I’m sorry if I disgrace the IT community with that.

I have looked at the settings that I can edit/change via the management software… I have a feeling I need one of those LAN Console cables to program the silly thing… Any expertise you have is greatly appreciated like I said, this is a learning experience for me, I know NOTHING on how to manage this switch.

My main concern with this switch is messing something up… the nice part is the CNA (link below) will let you back up settings and configurations, NOW THAT IS A LOAD OFF!!!
Since I was no longer scared to break it… I managed to solve my issue
