Eduardo, Your first priority should be to determine what hardware and software the switch is running. That way you know which commands and features are available to you. 'Show version' is pretty universal, otherwise 'show run', 'show hardware' and 'show ?' may help. If 'show interfaces fastethernet' does not work there are most likely no FE ports on the switch. Try 'show ip interface brief', 'show interface status' or 'show interfaces ?' to figure out what interface types are available. The command you already found, 'show interfaces', displays the interface types and their parameters, including details like utilization. Layer 2 switches do not typically correlate IP addresses to ports since that is a Layer 3 mapping. You need to find your MAC address and see what port the switch learned it from('show mac-address-table'). You should also check that you only see your MAC address on that port('show mac-address-table int x/x'), you don't want to re-vlan an upstream switch trunk. Once you have those details you should be able to find a user guide or command reference for the specific switch and IOS version, or guides for the interface type. Be careful reconfiguring, it is really easy to bring down your connection or the whole network. Make sure you don't stray from your contracted scope or cause unintended consequences. These show commands should be benign, but anything can happen so you use them at your own risk. Hope that helps, good luck, Dan -----Original Message----- From: Eduardo Espina [mailto:eduardomx () gmail com] Sent: Tuesday, June 13, 2006 7:21 PM To: pen-test () securityfocus com Subject: Physical ports in IOS Hi, I'm pen-testing a network and i've already gained access to a Cisco switch in certain VLAN; i'm stucked in getting a SPAN port in the physical port where i'm attached or changing that port to a different VLAN; "show interfaces fastethernet" doesn't work, and "show interfaces" just output the MAC address of the VLAN, but i can't find the way to correlate IP (mine) with the physical port (Fa0/3 i.e.). Some idea? Thanks, Eduardo. ------------------------------------------------------------------------ ------ This List Sponsored by: Cenzic Concerned about Web Application Security?
