I'm trying to configure a diagnostic port on my Catalyst Express 500 G-12TC switch.
I have followed the docs (http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml#Cat500) in setting up a diagnostic port, but I'm not seeing the traffic from the mirrored port. For example, I set up port Gi7 as the diagnostic port, monitoring port Gi5. The only traffic I see is broadcast and multicast. I do get a CDP packet every so often that says "Device ID: CiscoSwitch Port ID: GigabitEthernet5" but that's it.
Anyone know what I might have messed up?
