Mysterious Missing ARP Entry

I need some help with a strange new problem - a persistent missing ARP entry. We are a Cisco shop running WiSMs (6.0.199.4) with a mix of 1142s, 1131's and a few older 1242 APs. This past Friday we got a report of 5 XP tablets that could not use the wireless network. These are 5 out of a group

Justin, Thank you for pointing out that most management systems (AirWave, etc) use the MAC address as a unique identifier - it is supposed to be a unique hardware address. I've seen indication of that MAC on our Airwave Management Platform at Emory and can deduce we had 3-4 unique visitors, m

RE: [WIRELESS-LAN] Macbooks with odd Airport MAC addresses

Thanks. And the other sanity check would be that we haven't seen any evidence yet that this is anything other than someone configuring their NIC with this address. Perhaps we should be concerned about the security issues regarding this but until I see two different pictures of vendor MAC address

Re: [WIRELESS-LAN] Macbooks with odd Airport MAC addresses

keep in mind that in airwave, the clients are uniquely identified by their mac address, so you'll need to check if multiple usernames show up associated to this single mac address, if this is the case, most likely it is multiple clients with either a manually configured mac address (due to WEP s

RE: [WIRELESS-LAN] Macbooks with odd Airport MAC addresses

We too are seeing that MAC address in our logging for our wireless service, although it doesn't look like there is an actual full user(s) log-in. It might be pure chance that we have a device which should be using that MAC address but I'm not convinced! So the issue may not just be limited to th
