I am mirgrating over to a new Web Filtering application.  Currently the web filtering sofware I use allows me to use a  hub in order to monitor the traffic. But I am going to be forced to use my HP procurve switches for this purpose now.  I have 3  HP Procurve switches;
Procurve 2824 (J4903A)
Procurve 2848 (J4904A)
Procurve 4000M (J4121A)
I need to know how to enable port monitoring so that I can monitor traffic.  I wanted to use on dedicated port in the switch for monitor the network. I am not sure how to do this since my clients are spread out over three switches.  To be honest I am not sure how to do this even if all the clients were on the one switch.
I have logged into the switches.  The interface seems almost identicle on all three switches.
Thanks much.

John,

All of your Inet data will be headed out one port no matter how many switches you have as it will be the default gateway (your router or proxy).

I am too many years away from a procurve interface but it will be called port mirroring or port monitoring. Mirror the gateway port to this new one and connect your monitoring server. It should receive any data streams heading to the internet and be able to inspect them.

Thanks,

Kent

I am closing this as I found my answer and this response did help me a little. So am going to add this to knowledge base. But it's fairly easy to acomplish.  Simply open a telnet session with the switch.  [From command prompt enter "telnet 192.168.xx.xx" telnet and the ip address of the procurve switch.  Use letter M to bring up the main menu; Select SWITCH CONFIGURATION (usally the first choice in the menu)  Then select NETWORK MONITORING PORT.  
Enable Monitoring, select the port you wish to use, and then in the action field you can space bar through the choices till  you see MONITOR.  My configuration was simply.  I used the first port to be the port that was going to be doing the monitoring, and all the other ports had the monitor were configured to be monitored.  
I used this after researcing the manuals that came with the Switch.
Thanks
