I've got a few questions regarding simulating NX-OS to prep for the CCNA-Data Center exams. I have no access to Nexus hardware, but I have managed to download a NX-OS simulator from Wiley, and Freemium copies of Cisco's Nexus 1000V virtual switch for vSphere and Hyper-V straight from the company. Has anybody used these before? The first DC exam (640-911) is mostly a rehash of CCNA R&S, but there are going to be NX-OS specific question on the exam. I've got the CBT Nuggets and the Sybex book for that first exam, but the courseware for the second exam won't even ship until Feb 10th, so I have no way of knowing what it will be like, but it promises to be more indepth regarding the differences between IOS and NX-OS.
Secondly, I've got a trainsignal course for the new CCNA Wireless exam, but the only book available is the older rev. The new one doesn't ship until march. I've used plenty of 802.11 gear in the past (Cisco 350 AP/BR, Vivato, SmartBridges, Trango, Motorola Canopy, Areas WavLink DS3 radios, Tsunami, Hautespot, and Colubris and Bluesocket Gateway/WLAN controllers). I haven't used any of the newer Cisco APs (except the one day I worked with the 1100 models). If anybody has taken the exam, how much Cisco specific info is on the test? Would it be 60% general wireless information, 40% Cisco specific? Is there any kinda of simulator out there that would let me practice with the newer APs and their respective controllers (for Lightweight APs)? Or should I hit up ebay, Triton Datacom, or the like to try and find cheap APs and a controller or two?
Next, for anybody that's used GNS3, is it possible to integrate NX-OS simulated VMs into it? If so, would I need an image of NX-OS? I'd also like to integrate some of the available Hosts (virtualbox, QEMM) into a simulation as traffic generators. Is there a lightweight image file I could use to add to the simulation for those hosts? I don't need anything fancy, beyond being able to ping, tracert, and generate traffic. I would also like to know if anyone has managed to get GNS3 to support the 1 port T1 CSU/DSU WIC? I've got two 2610XM routers, each with 1 T1 WIC, but I would like to practice T1 bonding (haven't done it in about two years and I'm a little rusty).
Fourthly, has anybody else here used MikroTIK products? In the past, I've used their Hautespot AP/BRs (which also handled routing functions and VLANs) and used Ubiquiti radios cards, and I was given an evaluation bare RouterBOARD to try and turn it into a packet shaper several years ago. Has the RouterOS and hardware matured much in the last few years? Also, this Multilayer switch
of theirs looks really interesting to me, as a toy to practice with. Cheap Multilayer switch, with 24 GigE ports, and 802.11n looks like it could be a fun little addition to my lab.
Lastly, does anyone know of good vendors to with for used Cisco or Adtran equipment? So far, I've been using ebay, Triton Datacom, and one other vendor, whose name eludes me at the moment.
Thanks in advance!
