Does the firewall (named as "Vlan101"?) pass L2 traffic?


Please post relevant configs from the switches/routers/firewalls and the Aruba controller.

Re: ask vlan in controller

yes there is vlan 101 passing through firewall and i guess everything is fine, the only problem is when i give than  vlan 400 or 402 which is in existing their network my controller suddenly cant connect with ap or cant broadcast the ip address for ap in vlan 400 or 402 but everything is fine if i only create vlan 400 or 402 without ip address.

Re: ask vlan in controller

Is the port on the controller trusted. Did you recently install your first PEF licence?
