The specifications for this card seem to indicate that SPAN can be used for port monitoring with this router, however port monitoring commands (ie: show port monitor) are not available in the IOS (version 12.4). Any ideas on how to get it working?
Using a 9-ESW HWIC, I tried this, in global config mode (prompt=Routername(config)# ) after doing conf t monitor session 1 source interface fastethernet 0/1/0 monitor session 1 destination interface fastethernet 0/1/8
My objective was to copy all the traffic on interface 0/1/0 to the 0/1/8 interface, where I plugged in a PC with ethereal.
To stop the monitor session and remove the configuration do no monitor session 1
If this sort of thing works for you please say and confirm that what I did makes sense. I am a complete beginner with Cisco and read about this monitor session facility on one of the manual pages I have managed to print out. I have an idea that the Cisco itself can somehow display the packets going through but I have yet to discover what commands do this and how to ever stop such a process if I get it started.
