Will port monitoring affect regular traffic on monitoring box?
Posted on 2006-06-06
I have a Cisco 3500XL switch that my T-1 plugs into. FE Port 5. I had a laptop running Commtraffic plugged into Port 7, and port 7 was set to monitor port 5. See below..
interface FastEthernet0/5 - T-1 Line
port monitor FastEthernet0/5
The laptop has since died, and the only free machines I have available are servers doing some other things on the network, and plugged into the same switch. If I set one of the server ports to monitor my T-1 line, how will that affect regular internal traffic going to that server? Can the server still talk to the internal network or will it only point to port 5? Or will it still be able to talk to the rest of the network but take a performance hit?
The server I'm thinking of is a Proliant ML 370 1Ghz with 1GB of RAM, with Gbit fiber to the switch. It is currently running our AV and SUS server.
