https://community.extremenetworks.com/t5/extremeswitching-exos-switch/5320-48p-8xe-core-switch-setup/m-p/121855#M23211 <P>I am trying to set up an Extreme 5320 as my core layer 3 router. For love of all that is good in the world and all the computer power of AI, I can't seem to figure out the setup configuration in ExtremeCloud IQ pilot or Extreme Platform One. When I upload the config, I get several errors. EX: Lost connection, cannot remove the VLAN that was created from the initial onboarding, Error 500, etc.&nbsp; I have a pretty basic spoke and hope network, with a handful of VLANs, in-band management, so it shouldn't be that hard. I am starting to wonder if it's even possible to configure it as the core router using cloud, because of all the default safety guards in the GUI. Is it possible?<BR /><BR />What's best practice for something like this? I am doing a forklift replacement of all my switches, and coming from Aruba. I am overhauling the VLAN and subnets at the same time, so I need to do a hard cut over to prevent VLAN ID and subnet conflicts.<BR /><BR />How do you perform the cross-over from the onboarding internet to the static internet on it's on vlan without it loosing it connection and failing?<BR /><BR />How do you set the management VLAN? I planned to set it to the same VLAN as my DHCP server and other core servers to keep management simple since I am a one-man IT department. But this seems to add complication when setting network policy.<BR /><BR /><BR /><BR /><BR /><BR /><BR /></P> Tue, 02 Jun 2026 01:32:25 GMT OneManVsMachine 2026-06-02T01:32:25Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/5320-48p-8xe-core-switch-setup/m-p/121855#M23211 <P>I am trying to set up an Extreme 5320 as my core layer 3 router.
