A client on a site we recently took over has a Cisco ASA5505 as their gateway device. We have been provided with the login & enable passwords. I have some exposure to Cisco OS, but this has been mainly with routers and its just the basics that I know. (I attended a CCNA course but never actually sat the exam)
What I want to be able to do is monitor network traffic on the ASA, produce reports that will show me bandwidth usage etc, and preferably do this without spending money on software. I have read articles relating to NetFlow protocol, but from what I can determine the ASA device does not support NetFlow.
Can anybody help me? This is quite urgent
