Data Center CCIE #49450 My name is Rich and I talk about technology and other nerdy things. I've been in the IT business 2010 and currently on a team of computer systems engineers helping companies design and deploy data center solutions. Join me on this channel to talk tech and navigate what's going on in IT and technology.
Awesome! If you need more detail on this subject, check out my full IP Subnetting tutorial here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7hIbzlxbebc.html

Great video, however I'm missing the steps before adding the Fabric Interconnects to Intersight. For example do you have to do it directly during the deployment or can you do it afterwards. Also connect them directly to Intersight or use the hub appliance.
When you deploy the FIs initially you get the option to set them up either for UMM (UCS Manager Mode) or IMM (Intersight Managed Mode). If you set it up for IMM, there will be a lightweight GUI that you access via each FI's management IP (no VIP in IMM) to access the device ID and claim code, which are used to claim the FIs in Intersight. If you have already deployed in UMM, you either have to wipe the FIs and redeploy or use the IMM Transition tool, but either way downtime is involved. Unless there is a limitation to internet access in your UCS's location, you do not need an appliance to access Intersight.
Thanks for this great video! I do have one question I'm struggling with: I'm using your tool and and have an ip of 115.163.109.207 and a subnet mask of 255.255.248.0. I get everything right but the broadcast IP address. The solution per all the calculators I've used including yours give 115.163.111.255 as the broadcast address. In the example in your video, you have 172.16.15.25 and subnet 255.255.240.0; The broadcast address works out as follows: Broadcast: 10101100.00010000.00001111.11111111 Broadcast Address: 172.16.15.255 Well that makes sense, the 1111 = 15. But, in the tool when the problem is an ip of 115.163.109.207 and a subnet mask of 255.255.248.0, the broadcast address portion of the third octet is 00000111. I would think 111 =7, as in the your video example, 00001111 is 15, but apparently it's 111 and I have no idea why. Can you give me any clarity? Thank you!
With the following IP: 115.163.109.207 and subnet mask: 255.255.248.0 (Or 115.163.109.207/21) IP Address: 01110011.10100011.01101101.11001111 Subnet mask: 11111111.11111111.11111000.00000000 Network IP: 01110011.10100011.01101000.00000000 115.163.104.0 Broadcast IP: 01110011.10100011.01101111.11111111 115.163.111.255 The third octet is the relevant octet and the subnet mask splits it at 5 bits and 3 bits: Network 01101 | 101 Host The octet's network IP is as follows: Network 01101 | 000 Host --> (104) The octet's broadcast IP is as follows: Network 01101 | 111 Host --> (111)
If I were tasked with building out a network for multiple car dealership locations, I would look at the network needs for each location, then build out network architectures for each location. Then, connect the multiple locations together with an SD-WAN solution.
Thank you for posting this, I've Liked and Subscribed. You've placed a good deal into creating these videos to this high standard. It's appreciated. Thanks.
Hi Rich, given a migration scenario from a traditional network to an ACI environment using l2out , I have a question about gateway migration. Typically we would migrate the gateway last, after all the workloads, by enabling unicast routing on the bridge domain and shutting the l2out connection. However a client wants something different, he would like to keep the legacy gateway and have a second one on the same subnet in ACI, this new gateway points to a new firewall. After a workload is migrated, he would configure the new gateway in the server. He thinks that this approach would make use of the new gear faster instead of keeping the routing in the old infrastructure. Do you think this is possible? Never seen it done. (PS: l3out is not an option for him) Thanks a lot,
Having worked in this industry for +24 years its still difficult to keep up on the ever so changing technologies. Thank you so very much for not only your great intel but for the way to explain things!
Hi Rich, Gr8 video. I am trying to practice these with a intersight sandbox lab from devnet. However, post claiming ucs pod as IMM I can see FI's healthy. BUT while trying to create the domain profile (POD)/ FI's are not listing to select. I can see the lab is using ucspe, but as I am able to claim, they should be listed for assigning them a domain profile right? Really appreciate your guidence
