1 Question Finally they removed the Cat65 VSS Picture to explain FEX an N5k Can you swap the 5500 for the 7000 without issues? Can you swap the 5500 for the 7000 without issues? Is there a manager app that provides a single point of management for multiple 5Ks? Whats the status of IPv6 routing on the L3 cards in the Nexus 5k? Is the number of FEX limited by hardware or software? F cards 's with F2's running to 2232TM's via fiber. Servers connect via copper. Is it a true statement that only the 7000 supports L3 routing? 2000 fex connected to two 7000 using vpc? I saw a diagram that only showed the active/standby setup, but showed both for the 5000 switch fex connected to two 7000 using vpc? I saw a diagram that only showed the active/standby setup, but showed both for the 5000 switch. on N7k, can I have FEX ports allocated to multiple VDCs? on N7k, can I have FEX ports allocated to multiple VDCs? does the VM FEX requier the 1000V? With the momentum of 10GBase-T, why would one choose to go fiber to the server? with L3 module installed on 5K, how many FEX supported on 5K? thanks Answer No kidding right!?!?!? Well...depends Dude...what features are you using, are you looking at a M series or F series card set, etc... For the most part yes, but there are features that will exists only on N5K. You have all of your typical managment tools including DCNM. Hopefully soon Dude. We are working on this now It is a combination of the two. Each FEX adds CPU load. Here are the current limits for Nexus acenter/nexus5000/sw/configuration_limits/limit s_521/nexus_5000_config_limits_521.html SHould be OK. I really hate to gave a solid endorsement without knowing more about the network. With what you have said; yes No. The N5K supports L3 with an expansion module. We dont support that today, but we are going to support in a future NX-OS release Also, remember, given that Nexus 7000 already has full redundancy including dual-supervisors, power supply redundancy, fabric redundcany and HA, this feature is not as critical on Nexus Lot of customers connect FEX ports to multiple LC for redundancy 16 FEX in L3 mode No, all FEX ports must belong to same VDC No, VM-FEX does not require Nexus 1000V Fiber will always have a longer reach to the server and is EMI does not affect it. acenter/nexus5000/sw/configuration_limits/limit s_521/nexus_5000_config_limits_521.html

2 with L3 module installed on 5K, how many FEX supported on 5K? thanks Praneetha - was that answer to my question? Praneetha - was that answer to my question? is there still a limit on the # of FEXs able to be attached if the enterprise routing license is installed on the 5ks? Will VM-FEX/Adapter-FEX only be available with the Cisco CNAs? So only the N2K-C2232PP-10GE supports FCoE at the moment right? We can support 16 FEX in L3 mode Sorry, wrong question being answer. All FEX host ports must belong to same VDC For Adapter FEX we are working with 3rd party companies as well. At this time only FCoE is supported on fiber or SFP+ cables fex connected to two 5000 using vpc? fex connected to two 5000 using vpc? You can also have evpc where the FEX is connected to two different N5K and the host is active-active vpc Well I forgot the B22HP. That one should support FCoE. ;) n5k suport ipv6? n5k suport ipv6?. B22 line of FEX also support FCoE. I was orginally thinking of rack mount Nexus 2000, with the GoldCoast release onward That would be 5.2 release Will we be covering some of the different 2k to 5K uplink options for providing HA and not single point of failure?. We will have connection diagrams will the nexus 2000s ever support local switching between No plans at this time. will the nexus 2000s ever support local switching between We want to keep N2K simple to provide a single pane management. will the nexus 2000s ever support local switching between But we are constantly looking at customer requirements for the future products We have a vendor recommending that since we are planning on using several vdc's on our 7k's, then they recommend to use seperate 5K's and 2k's per vdc instead Best to bring network design questions to the of carving up a set of common 5K's and 2K's with vlans. Is Cisco Account teams so that the correct this a best practice/normal tip? resources can be engaged. The FETs are used only between Nexus 2000 and Will FETs ever be orderable separately w/o being part of a parent switch. So they are currently only sold N2K purchase? with Nexus 2000 Will FETs ever be orderable separately w/o being part of a yes, it is orderable, however its an hidden SKU - N2K purchase? FET-10G= T- copper, P-is fiber uplink to parent switch. E What does TP-E stand for? with extended buffer. We cannot comment on product that is not No 40G modules for the 5k on the horizon? shipping

3 10GT over copper... what media is support again? Is there oversubscription in the 2232TM-E? What does M of TM-E stand for? is FCoE supported on 2248T-E? "M" for module but it is not Field Upgradeable... will there be SFP+ 10GBase-T transceivers for a 2232PP? Talking about the B22, what is the technical reason why I m not able to enable turn on the location-led? Module can be replaced? does this blade fex basically replace the Nexus 4k? What is the backplane throughput of the 2232TM-E? Do the ports share capacity to the backplane in 8-port groups? What is the backplane throughput of the 2232TM-E? Do the ports share capacity to the backplane in 8-port groups? Does the 5K support ISSU? How would the OS upgrade affect the 2K traffic flows? It is really hitless? does the B22 work in an IBM chassis? CAT-6, 6A, 7. Best to reference the datasheet for the latest update. Depends on how you design your connections. M" for module but it is not Field Upgradeable...if you look closely there are screws on that part of the Network interface ports" That is a 1G FEX. You have to have 10G speeds to support FCoE. FC native is 1,2,4, 8G. Currently the 10G PHY uses more power than the power budget on a SFP+ form factor. So no such device exisits. As the power usage comes down, it may be possible in the future. The location LED ir controlled by the chassis managment board. There is no way to send commands between the Nexus and the chassis managmenet board of the chassis Nope. Depends on how the uplinks are connected. Static pinning or port channel. typically customers use port channel and thus any host facing port can go up the network facing ports. If all network facing ports are connected, then you can think of it as a 80G port channel link for the FEX. N5K supports ISSU. It is really hitless. At this time, there is not a B22 for the IBM chassis. Please work with your account team. it's 4:! oversubscribed 4: porst down 1/10GBASE-T + 8 SFP+ up in 1Gig mode, it's linerate

4 only if STP is not active you lose ISSU on the N5K if there are ports running regular yes, there are specific guidelines to get hitless spanning tree (i.e. none edge stp ports) ISSU with regard to STP root can you dual connect a FEX to multiple 5000's for redundancy? Also, is there a 40Gb/s option available for that interconnect? can you dual connect a FEX to multiple 5000's for redundancy? Also, is there a 40Gb/s option available for that interconnect? thats an advantage of use N7k for parent switch if you have an STP environment No, I'm asking the opposite..can you connect a single FEX to multiple 5000's? you can connect multiple FEX to N5K. There are plans for QSFP+ option for interconnect. No, I'm asking the opposite..can you connect a single FEX to multiple 5000's? great thanks. What encapsulation does the FEX use? i may have missed it, but what is the difference between pinning and port channel..thx i may have missed it, but what is the difference between pinning and port channel..thx lol it was just explained..thx! Are there any advantages to using Pinning rather than Portchannel? vlan assignment in port profiles as well? we will have Nexus 5548UP, and Nexus 2224TP, and we also have HP C7000 with HP Flex10 balde, where should I plug HP Flex-10 into? in Nexus 5548? will changes to port-profiles be replecated to already assinged interfaces? can he VNTags be view Is there a VNTag table Another thing, our core will be 6509E with 2T engine, and downstream Nexus 5548, where HP Flex10 better be plugged in is VM FEX and extra license? Does VMFex count against your total Fex count limit? so FULL active / active from the server is supported (not just ODD / EVEN vlans across differnt links) yes, a single FEX can be connected to two N5K. There will be some topologies shown later on its a VNTAG - Jeffrey will talk about it with pinning you pin specific host ports to netwrok interfaces with port channel, hashing to NIF is based on flows it's consistency, you know the behavior and how much bandwidth each host will have access to - most customers use PortChannel, simpler yes - best is to connect switches to N5K There are 802.1BR tables that is viewable 5548 is best since it's your acces/aggreg, but both work there is a license but zero cost no there is another vmfex limit, independant yes, with vpc, it's already active/active. With fabric path, it's up to 16 path active/active

5 Can 2 k support fabric path? Can 2 k support fabric path? dummy question here, we have brocade 5100 Switch for our san storage, can nexus 5548 replace it? with vpc+, the virtual switch (parent switch + N2K) can be seen as one switch in the fabric path cloud Fabric Path is on the parent switch...it is not run at the N2K. With our 5548UP it can support FC as well as FCOE/CE. What if I have multiple servers which needs to be part of two or more VDCs and I have only one FEX device on the Rack. What is the best way to integrate with Nexus 7 K. This is reference to my earlier question - spaning fex HIF across multiple VDC Please reach out to me pmanthra@cisco.com", I can work with you" for the N5K - between N2K & N5K, you can use 16 paths for the whole 5K or between the 5k & 2k vpc. any particular SFP+ need to be used for connect to HP SAN 6500 with 8GB plug dummy question: If we have Nexus 2000 VM-FEX, do we still need Nexus 1000v on Hypervisor layer? no you don't could we share the comparison between Nexus 1000v and Nexus 2000 VMFEX? it's actually n1000v & VMFEX can copy the QA session for future reference.. I am not able to copy.. will 2k support fc?
