Please see my attached network diagram.
As you can see my entire access layer switches (2960s) connect to my core (3850) via fiber 1Gbps.
The Cisco ASA connects via EtherChannel (5x1gbps) to my core switch.
All my routing is done on the cisco ASA with sub interfaces. I have about 15 vlans/sub interface on my ASA.
All traffic between vlans is controlled via ACL’s and IPS inspection.
My question is will this create a bottleneck on the firewall as my IPS throughput on Cisco ASA 5516x is 450 Mbps and all my servers are also in a separate vlan e.g. exchange server, file server, dc’s, proxy servers, SQL servers and all departments are in a vlan e.g. HR, Finance
