We have had similar issues but without HSRP. Layer 3 Cisco 6500 have a nice "feature": all interfaces on the L3 part of the 6500 have the same gateway MAC address. So, when a user enables bridging between wired and wireless (mostly with XP machines!!!) there is a race condition for the MAC address of the gateway that's being advertised on the wireless and wired at the same time. Wireless lives, but Wired dies! According to Cisco there is a way to specify yourself the MAC address of a gateway on "layer 3 switches".
Another fix would be to enable ARP-Proxy on Access-Points but it opens another can of worms Regards, Philippe Hanset University of Tennessee On Tue, 22 Jun 2004, John J.
