Cisco Firewall :: Enabling Traffic On E0/2 And E0/3 Ethernet Ports - ASA 5510

enabling traffic between interfaces on the ASA 5510. Of course I have an outside interface E0/0 and an inside interface (E0/1) for normal operation. The idea was to enable one of the remaining interfaces on the 5510 to attach an internal network resource to for management in case we lost our switch. I am using E0/0 as the outside interface and the inside interface is E0/1. I am wanting to attached a management device on the same inside network IP address range for simplicity. I have E0/2 configured for the same security level (100) as the other inside interface and I also have enabled same-security-traffic permit inter-interface as well but I still cannot access the device on that port. Is there something else I am missing? I guess the best way to explain this is that I want ports E0/2 and E0/3 to act like a "switch" so to say...... The ASA 5505 lets you do this pretty easy but having trouble on the 5510.
