Recently we have changed our ISP.We have leased line connecting to Cisco pix 515E Firewall. We have not used any router. My question is I want to check the utilization of this lease line and my ISP says enable SNMP on the Cisco Pix. But I dont want to enable SNMP on PIX because of SNMP has lot of vulnerabilities. So without enabling SNMP on PIX how can I check the utilization of my lease line? When using previous ISP we have not enabled SNMP. They have given us username/password and web address from which we monitor the link. Also how can I know which user is downloading more and utilizing maximum bandwidth

You can enable SNMP on the inside interface of the PIX without exposing the outside -OR- if you are dead set again that enable SNMP on the device connected to the PIX inside interface and monitor it.

How can I know which user is downloading more and utilizing maximum bandwidth in my inside network?

To do that you will need a netflow capable device and a netflow analyzer.   The PIX does not support netflow.

Here's a free netflow analyzer

Here's some details on netflow.

This tool will help you locate a netflow capable device.  Most any Cisco router will work.

The easiest way is upgrade PIX 515 to ver 7.x or above. Run ASDM, you can see the real time traffic bandwith usage with resoluation of 5 seconds.

PDM shows you the same thing and does not require 7.x
