Ding, A big flat network is only attractive until you have many users on it that destroy the quality of service. We ran a big flat network with over 4000 users and eventually moved away from it. You can live with the big flat network but you have to constantly filter new broadcasting protocols

We use several /20 and /21 VLANs across each campus, with traffic generally routed only if it needs to reach another VLAN (or campus). We DON'T, at Aruba's recommendation, do that for our wireless services, instead deploying them in multiple /24s (several assigned to each SSID). If I recall c

Many of our windows 7 clients have this problem. We found a solution: in the "Network Properties", go to the "Security" tab, there is a button named "Advanced settings". Play with the check box of "Specify authentication mode": some clients should check it, and others should uncheck it. Good l

I've read anecdotal accounts that some NIC drivers default to 00:11:22:33:44:55 when an error occurs or when it's unable to determine/set the true Mac address, I didn't think that parallels would generate a fake nic though.. --- Justin Hao On Sep 28, 2010, at 2:39 PM, "Hanset, Philippe C" wrot

One more piece of info on the 00:11:22:33:44:55 weirdness: We have a user registered in NetReg with MAC address 00:11:22:33:44:55, It is an Imac and was registered on our network in Parallels (browser reference is Windows NT 6.1). I wonder how many of these strange MAC addresses are generated by

The PC should request an arp for the gateway. Do you have any arp filtering along the path? We had a case where some wireless array will drop arp request from windows vista computers. Disabled the arp filtering or arp broadcast restriction fixed the issue we had. Schilling On Tue, Sep 28, 201

No, it is not the base SSID. No ARP is being sent from the WiSM. Should the PC request the ARP or should it come unsolicited? The PC does not show any request for one. -jcw[cid:image001.jpg@01CB5EE5.62050910] - John Watters

The SSID that fails is being broadcast. The issue persists across all APs and across WiSMs and even across 6506 switches (the ones with the WiSMs). Will look for a different NIC driver -- pretty sure they are running the latest version, will try for a level or two back. All tablets have the same

Does the WEP ssid that is not working happen to be the radio's base BSSID? We have a similar issue with a different vendor and different device. I would say that you may need to end up performing a packet capture to see where the traffic is dropped. == Ryan Holland Network Engineer, Wir
