And if I already have bought AP1560D? What are my options? Have you heard that vWLC with these APs is not a solution to bridge two sites?

I've read that this equipment doesn't have autonomous software and that leaves us with Mobility Express or WLC.
I also think that by now there is no Mesh support in ME? So only WLC left.
And by WLC I mean the real physical one, as I was told that vWLC wouldn't work?!?!
Can anyone validate this information?

Hi! Could it be possible to insert clients into the database? We are trying to migrate the clients from another database to avoid new registration of the already registered clients... Thanks TM

We’ve found the origin of the problem. It had to do with a badly configured gateway IP address in the DHCP Pool, for the network in VLAN1. We were experiencing asymmetric routing with one leg of the communication been routed through a Cisco 800 series. We've found that this issue was ongoing for the past few months. Testing a new access-point took us to wrongly think this was a wireless issue. Thank you for your help. You have been really useful!

Both PCs on Wireless Same VLAN WPC1 (VLAN2) -> WPC2 (VLAN2) 39.19 Mbit/sec WPC2 (VLAN2) -> WPC1 (VLAN2) 31.31 Mbit/sec Different VLANs WPC1 (VLAN1) -> WPC2 (VLAN2) 9.15 Mbit/sec WPC2 (VLAN2) -> WPC1 (VLAN1) 37.36 Mbit/sec Both PCs on Wired Same VLAN PC1 -> PC2 670 Mbit/sec PC2 -> PC1 705 Mbit/sec Different VLAN PC1(VLAN2) -> PC2 214 Mbit/sec PC2 -> PC1 (VLAN2) 9.8 Mbit/sec !!! (Here's the real problem!!!) So I guess I can rule out this beeing a wireless issue! Still have to find the problem anyway... I missed this result the first time because I was only testing one direction... I've allready upgraded the switch to the latest IOS release, as I have with the access-point...

Hi! Thank you for your answer, as you pointed out, there are very large differences dependant of the stream's direccion. Here are the results: PC1 -> WPC1 9.8 Mbits/sec WPC1 -> PC1 76.52 Mbits/sec PC2 -> WPC1 56 Mbits/sec WPC1 -> PC2 85.79 Mbits/sec There are no other wireless clients involved, but it's obviously direction dependant...

Ok, I shut down the 5GHz Interface, and enabled the 2,4GHz interface. Got the same result (8.46Mbit/sec). Got back to the 5GHz interface using only 20Mhz width, got (9.37 Mbit/sec). It took me a bit more of time updating the driver. I thought maybe it could be it. I was using Microsoft Driver. Changed it to Intel drivers, but got the same result (9.38 Mbits/sec). I'll try to test with different hardware I get my hands in a different notebook. So... none of your suggestions mada a difference.

Thank you for your answer. I wanted to keep the lab as small as possible, so the routing is done by the 3560. I can see that while routing between two different VLANs the device is at least capable of doing 220Mbits/sec so I think this might be somehow a limitation on the routing capacity in this switch. Still 220Mbits/sec is way more than the nearly 10Mbits/sec i'm getting...

Hi, I have a problem regarding throughput over wireless when the peers of the data transfer are in different VLAN (separate networks). Topology: I have a 3560 L3 switch configured with two VLANs, VLAN1 is the PC Wired network and VLAN2 is the PC Wireless network. Connected to this switch I have a 1602i standalone access-point. I have connected two PCs via Gigabit Ethernet ports to both VLANs (wireless is disabled). I have one wireless client connected via 802.11an (disabled 802.11bgn to rule out interferences) using 40MHz channel width in the wireless network (VLAN2) Device description: PC1 - Connected via Gb ethernet to VLAN1; PC2 - Connected via Gb ethernet to VLAN2; PC3 - Connected via Gb ethernet to VLAN1; WPC1 - Connected via 802.11n to VLAN2; Here's the the tests I've made: I've used both iperf and multiple paralel FTP sessions with similar results. PC1 -> PC3 447 Mbits/sec Note: no routing involved, no wireless involved PC1 -> PC2 220 Mbits/sec Note: inter-vlan routing involved, no wireless involved PC2 -> WPC1 80 Mbits/sec Note: no routing involved PC1 -> WPC1 9.8 Mbits/sec <== PROBLEM Note: inter-vlan routing involved As you can see I have nearly a 10x factor decrease in performace in the last test presented. I can't find why this happens! I've already updated both the access-point and the switch to the latest version avaliable. I've also used an old AP1100G and got the same result, around 9.8Mbits/sec when in different networks and around 17Mbit/sec when in the same network. I've tested with diffent security settings in the wireless ssid, but I always get the same results... a huge performance degradation when connecting two devices in different VLANs. Any suggestion? Thanks!

Thanks for you answer! I've found this on the AP's datasheet: "Certified for use with antenna gains up to 6 dBi (2.4 GHz and 5 GHz)" Could it be a problem that the AIR-ANT2547V-N has 7dBi in the 5Ghz band? Gain (2400-2483 MHz) 4-dBi Gain (5250-5875 MHz) 7-dBi

Hi, is it possible to use the outdoor AIR-ANT2547V-N dual-band antenna with AIR-CAP1602e access-points, using a N-Type to RP-TNC converter? We have a couple of 1602e AP and we need to go for outdoor coverage, and we were thinking about installing the AIR-ANT2547V-N atennas outside the building wile leaving the AP itself indoors. We cannot use the recomended AIR-ANT2544V4M-R because of its size and install location. Best regards, Tiago

Hello, I've been digging a bit deeper, and found that 6611 also suports LLDP. The problem is that it seems that it has to be LLDP-MED, an extension to this open discovery protocol. To HP 2510 Switch supports LLDP but still I doesn't advertise the Voice VLAN. We also have Cisco 7931 Phones in this switch and we managed to get them working by manually set the VLAN ID. How can I do the same in the 6911 model??? Regards, Tiago Molinos

Thanks for your reply. Do you know can I select the VLAN in this specific (without screen) new model? I think that's my main problem... I was wondering if I could connect the phone to a cisco voice vlan configured switch, let the new phone learn the VLAN IDs, and then, connect it to the HP one... Tiago
