Notes on CBAC Performance

Sizing CBAC performance and selecting the router for your network perimeter depends on many factors: for example, the bandwidth of the WAN link you need to support, the average packet size of your traffic, and the IOS services you need to run on the router. Although there are no hard and fast rules, Table 8-1 offers some general guidelines—you might find that your particular environment is more or less forgiving. These guidelines assume the firewall router is dedicated to CBAC processing.

Table 8-1. General Guidelines for CBAC Routers
Router Platform Typical CBAC Capability
Low-end (Cisco 1600, 2500) Up to T1 (1.544 Mbps)
Mid-range (Cisco 2600, 3600) Up to 5 Mbps
High-end (Cisco 7200) Up to T3 (45 Mbps)
