RE: WCS to NCS migration trouble
It was over 10 gigs, I had to get a patch from TAC to support 10 gig zip file.

We just bought Cisco NCS, managed to get it installed (virtual appliance, fwiw) and seems to work well in the short amount of time I've played with it. We wanted to import everything from WCS, so I followed the instructions on upgrading it to a version that allowed for exporting (7.0.230.0), which produced wcs.zip. On the NCS server (1.1.0.58), we were unable to get it to connect via ftp to our ftp server to grab the zip, but sftp seemed to work (the 'show rep repname' command worked, where it wouldn't with ftp). Anyhow, I ran the 'ncs migrate wcs-data wcs.zip rep ncs-ftp-repo' command and only received the below output... Initiating WCS 7x DB restore . Please wait... INFO: no staging url defined, using local space.rval:2 Is this normal? Should I see a status somewhere? I've let the thing go for hours with nothing else showing up on the screen. Ctrl-C sends me back to exec mode where I can start ncs again, but after logging into NCS, I see no new data (controllers, mse, etc). If you went the WCS to NCS migration route, how was your experience?

Re: [WIRELESS-LAN] You knew it was coming...Airplay/Apple TV support for instructors.
Awesome guide, I wouldn't have thought of using the Multicast VLAN feature to bridge bonjour between our 802.1x SSID and our PSK SSID. Thanks for passing on this document. We are doing a test (rather unsuccessfully) with one department on our campus, where I have both the AppleTVs and the i* devices doing airplay on our PSK network. It has been a rather large support investment to touch every device whenever apple nukes the config on the AppleTVs during a software upgrade. And as of the last month or so, whenever we turn on screen sharing, the APs force a re-auth of the AppleTVs. I was hoping that 7.2 would fix some bug that is causing this, but no luck so far. I turned on the Multicast VLAN feature on our .1x SSID (on a lab controller of course) and set it to the vlan of the PSK network. Now I can get the AppleTVs to re-auth using an i* device on our .1x SSID! Very exciting stuff here, thanks again for the doc. -Luke =-=-=-=-=-=-=-=-=-=-=-= Luke Jenkins Network Engineer Weber State University ljenk...@weber.edu On Feb 23, 2012, at 12:47 PM, Jeffrey Sessler wrote: Wanted to pass this on - it's not published yet on the Cisco site.

Where did you get that 12 client number?? At Liberty University, we have successfully had 20 students per AP with 5Mbit streams. In a Lab test situation, we had 30 clients all streaming on one AP-125 access point. Multicast on 802.11 uses the lowest rate which is 6Mbit for 5GHz networks. That is why Aruba developed their multicast technology. We have been using it since it was introduced.

So it's not just about the bandwidth. B'cast M'cast use the lowest configured data rate of the AP - just like wireless management frames. This means that even for 300Mbps 802.11n network is reduced to 24Mbps or less. That also ties up airtime that could be given to faster clients as well, since transmitting data at a lower data rate consumes more time that transmitting data at a higher data rate. So even if it is a low bit-rate stream, it takes away more available bandwidth from other clients. Aruba has a method that takes b'cast m'cast and converts it to higher speed unicast traffic to each client. This gives better results for about up to 12 clients on an AP/radio. - Stan Brooks - CWNA/CWSP Emory University University Technology Services 404.727.0226 AIM/Y!/Twitter: WLANstan MSN: wlans...@hotmail.com GoogleTalk: wlans...@gmail.com -Original Message- From: Mike Goebel michael.goe...@wmich.edu Reply-To: The EDUCAUSE Wireless Issues Constituent Group Listserv WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Date: Wed, 22 Feb 2012 11:09:16 -0500 To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] You knew it was coming...Airplay/Apple TV support for instructors. Has anyone actually tracked how much bandwidth/usage Bonjour coughs up across their wlan infrastructure? I haven't analyzed it, and while it could be bandwidth hungry, it appears to me that will be more with device to device. I'm playing devils advocate here, but is a 6 meg stream on an N access point both ways really going to be crunching anyone? I'd be worried about G yes, but N with a gig uplink? I do find it unnerving that all the bonjour devices are able to find each other and potentially create a lot of traffic, but 99.9% of the time I don't see anyone working any access point very hard.

Mine was the same way, started it one morning and came back the next morning to finally find it complete. My WCS export zip file was 14GB.
