Do a show arp on that switch or the router and you'll usually see the AP's MAC for all IP's on the wireless segment, the AP itself segments the network as that's the simplest way to implement an AP. A good example of something with single MAC and MAC cloning capability would be Broadcom's SoC Access Point chips. Most laptop implementations today get 2 MAC's because they use separate silicon for the Ethernet PHY and the Wifi controller, with the Ethernet being onboard and the WiFi being a mini-PCI card (this is the setup in the ipconfig dump you posted earlier), you see the single-silicon implementations in AP's and such and that's the only time you'll usually see a single MAC across WiFi and Ethernet unless someone's been mucking with MAC cloning. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
