On a Cisco router 831 how can I tell if we have 'Cisco IOS Firewall Software'?
In the white paper 'Cisco 800 Series Routers, Internet Security for Small Businesses' it says the following:
"Cisco IOS Software, the operating system on all Cisco routers, provides the intelligence behind the Internet and the firewall capabilities in router-based, integrated firewall solutions. Cisco IOS Firewall Software, an optional feature set specifically for integrated firewall applications, enriches the basic security capabilities of IOS software with context-based access control (CBAC), a connection-oriented stateful packet inspection system. "
Given then that Cisco IOS Firewall Software is an optional feature how can we tell if our current unit has it or not?
Thanks in advance,
