Given that I have same topology as shown in Internet Edge Cisco IPS Design Best Practices and basically inserting 4270 Appliance into an INLINE mode.
Core and Distribution Switch = Layer-3 routed links
Distribution Switch and ASA = Layer-2 access port
I'm wondering how IPS sensors be configured? I think I understand belows method but since my Core/Distrib is a layer-3 links, not sure which method gonna work since most require two vlans ...
1. Interface Pairing
2. VLAN Pairing
3. VLAN Group
Anyone has same experience?
Thanks in advance ...
