Simulator/Emulator for Cisco Nexus 7k, 5k

Do you guys know any good simulator or emulator for Cisco Nexus 7k or 5k ?

There aren't any at the moment. I have heard that Cisco has an internal one that is proprietary and not available to the public. Our only hope is to wait for the release of Cisco's VIRL aka Cisco Modeling Labs and hope that an NX-OS emulator will be included. However, when I was checking it out at this year's Cisco Live the current version did not have one :(

Data Center Hall Temperature for Cisco Nexus 7010

Hi,
I Have a Nexus 7010 that sometimes raise an alarm about temperature thresholds that are being exceeded.... I was wondering if Cisco has a recommendation (or best practice) about the correct temperature that the Nexus need in the cold and hot hall of the data room. I know that the operative temperature of nexus is 0 - 40°C but i´m not sure if my halls are in the best temperature.

Hi Salvador,
As long as you keep your Data Center environment in this operative range your N7K will be fine.
The usual is around 18°C and 24°C.

Cisco Nexus 5548 device

Hi,
Can you please let me know how to get (command) Manufacture date for Cisco Nexus 5548 device.
Appreciate your support.
Thanks,
Brahma

Hi Brahma,
I dont believe there is a command which would give you the Manufacture date directly, however there is an old theory which speaks about decoding the date of manufacture from the serial number.
Excerpt is as captured below:-
The date code is built into the serial number. The format is LLLYYWWSSSS, where:
LLL is the location at which the unit was built.
YY is the year that the unit was built (1997=01, 1998=02, 1999=03, 2000=04).
WW is the work week of the year that the unit was built.
SSSS is the serial number.
Else the account rep would be able to give more details by backtracking the serial number to the inventory.
HTH,

Cisco Nexus 1000V InterCloud

Need download link for Cisco Nexus 1000V InterCloud

We had a simliar issue with 5.2(1)SV3(1.3) and found this in the release notes:
ERSPAN
If the ERSPAN source and destination are in different subnets, and if the ERSPAN source is an L3 control VM kernel NIC attached to a Cisco Nexus 1000V VEM, you must enable proxy-ARP on the upstream switch.
If you do not enable proxy-ARP on the upstream switch (or router, if there is no default gateway), ERSPAN packets are not sent to the destination.

After enabling 'ip proxy-arp' on the upstream SVI it started working properly.

Cisco Nexus 1000v Virtual Switch for Hyper-V Availability

Hi,
Does anyone have any information on the availability of the Cisco Nexus 1000v virtual switch for Hyper-V. Is it available to download from Cisco yet? If not when will it be released? Are there any Beta programs etc?
I can download the 1000v for VmWare but cannot find any downloads for the Hyper-V version.
Microsoft Partner

Any updates on the Cisco Nexus 1000v virtual switch for Hyper-V? Just checked on the Cisco site, however still only the download for VMware and no trace of any beta version. Also posted the same question at:
http://blogs.technet.com/b/schadinio/archive/2012/06/09/windows-server-2012-hyper-v-extensible-switch-cisco-nexus-1000v.aspx
"Hyper-V support isn't out yet. We are looking at a beta for Hyper-V starting at the end of February or the begining of March. "

Cisco Nexus 5K + Micrososft Radius for Admin Authentication

Hi,
I have cisco 3750 switches configured to use MS radius for administrator authention. however, now I would like to add our cisco nexus switches to MS radius as well so that administrators are authenticated against the Microsoft radius for admin authention.
I tried it earlier but it won't accept 3750 commands.. Can you please help with me with a configuration example please that I can follow?
the commands I have used on 3750 are as follows:
aaa new-model
aaa authentication login vtylogin group radius local
aaa authentication login conlogin group radius local
aaa authentication enable default group radius enable
aaa authorization console
aaa authorization exec vtylogin group radius local
aaa authorization exec conlogin group radius local
radius-server host x.x.x.x key SECRETE
line con 0
exec-timeout 5 0
authorization exec conlogin
logging synchronous
login authentication conlogin
line vty 0 4
exec-timeout 0 0
authorization exec vtylogin
login authentication vtylogin
transport input ssh
line vty 5 15
exec-timeout 0 0
authorization exec vtylogin
login authentication vtylogin
transport input ssh

I have never done this before with ACS but not with NPS. However, you are in the right path. Nexus uses NX-OS which is different in some regards to regular IOS. One of those differences is the AAA setup. In NX-OS you assign users to roles. So for full access you will need to return the following attributes from your Radius server:
Attribute: cisco-av-pair
Requirement: Mandatory
Value: shell:roles*"network-admin vdc-admin"
For more information take a look at this link:

Nexus 7 client for Cisco OnPlus

I know Cisco has been hard at work on the Android Tablet client for OnPlus but could you please approve the smartphone version for the Nexus 7 or adapt the tablet version and release it for the Nexus 7?

Michael Stevenson wrote:I would consider this a very "mainstream" device and I have a feeling most Android users would agree.
I completely agree. We understand why it is not showing in the Google Play store and are looking into how we can correct the issue now. As I have more information, I'll provide an update.
Thanks again for your patience.

Command for view i/o rate cisco nexus

Hi
I need a command for view input and output rate on all interface for device nexus 7000 and nexus 5000
The command sh interface show more information, I only need view rx and tx
on switch 3750, 2960 i use sh interface summary and in nexus do not exist
Regards

Hi,
Show interface xxx | inc rate will give you in /out rate.
For example -sh int e1/1 | i rate
For show interface summary you can use grep feature on nexus multiple Include and exclude are possible.
show interface E1/1 | inc rate|MTU | exclude pps
Just to see interface counters -
show interface counters detailed all
Hope this helps.
Thanks

Routing issue between Cisco Nexus and Cisco 4510 R+E Chassis

We have configured Cisco Nexus 7K9 as core and Cisco 4510 R+E as access switches for Server connectivity.
We are experiencing problem in terms of ARP learning and Ping issues between Cisco Nexus and end hosts.

Hi,
So you have N7k acting as L3 with servers connected to 4510?.
Do you see the MAC associated with failing ARP in 4510?. Is it happening with all or few servers?. Just to verify if it is connectivity issue between N7k and 4510, you can configure an SVI on 4510 and assign address from same raneg (server/core range) and perform a ping.
This will help narrow down if issue is between server to 4510 or 4510 to N7k.
Thanks,
Nagendra

How do I set up an emulator for testing my application?

I'm starting to wade into GPIB and cannot seem to find the best way to continue given all the components (not meaning ActiveX) required to assemble a semi-reliable development and testing environment for beta rollouts.
I have set up my design environment. Now I need a way to emulate some of the equipment I will be developing for so that I may test my apps before final testing on the actual equipment (which I obviously have no access to at this point).
Given that.. am I correct in understanding that LabView or IVI allows this type of functionality? If so, here are my specific questions regarding development:
1) Do I currently need any hardware or can the GPIB device list be populated from IVI/LabView emula
tors? In other words... how do I make the 'link' between these two technologies?
2) Can IVI/LabView run on the same machine as my test application, or is a secondary machine required?
3) Is there a general punch list of software (LabView, etc.) I might need in order to get this going?
4) Any general (or specific) overviews that may help me get over this hump would be greatly appreciated.
Charles

Whether or not you are able to simulate your hardware will depend on what method you are using to program it. If you are programming the instrumentation directly using the GPIB ActiveX control or GPIB calls directly you will not have the ability to do simulate in software. If you are using an instrument driver, however, you will be able to do simulation if the instrument driver is IVI compliant.
Assuming that you are using an IVI-compliant instrument driver, here are the answers to your questions:
1. You do not need any hardware whatsoever. You can either specify to use simulation in your code by using the InitWithOptions functionality and specifying "SIMULATE=TRUE" in the option string parameter. You can also set things up externally so that you can alter simulation strictly through the IVI configuration so that your code doesn't have to change.
2. It will run on the same machine as your code. As far as your application is concerned, it will not appear any differently however no GPIB communication will occur.
3. IVI compliant instrument drivers for all of the GPIB hardware you are using. These are available for download from ni.com.
4. I think that there may be some IVI-related application notes.
Assuming that you are not using an IVI-compliant instrument driver and instead are either using a non-IVI instrument driver or making GPIB calls directly, things can get a little more elaborate. If you want full emulation capability you'll need to write another piece of software that emulates your device. This can be done in LabVIEW or any other ADE of your choice. What you'll need is a second GPIB card (to act as your device) that you'll cable to from your main computer. That card can live in a second machine or in the same one as your main application. You may want to put it in a separate test machine just to keep things a little cleaner.
If you go with this approach, it's not too difficult to write an emulator for a single device (or at least that functionality of a device that you use) per GPIB card. It will be more difficult to write an emulator that emulates multiple devices using a single GPIB card. In other words, you may want to use a separate GPIB card for each instrument you want to emulate. I wrote such an emulator some time ago but can't seem to find it. In any case, it's probably only a couple of days effort.
To make a long story short, your life will be a lot easier if you have IVI-compliant instrument drivers available for the hardware that you are using.

FCoE with Cisco Nexus 5548 switches and VMware ESXi 4.1

Can someone share with me what needs to be setup on the Cisco Nexus side to work with VMware in the following scenario?
Two servers with two cards dual port FCoE cards with two ports connected to two Nexus 5548 switches that are clusterd together. We want to team the ports together on the VMware side using IP Hash so what should be done on the cisco side for this to work?
Thanks...

Andres,
The Cisco Road Map for the 5010 and 5020 doesn't include extending the current total (12) FEX capabities. The 5548 and 5596 will support more (16) per 55xxk, and with the 7K will support upto 32 FEX's.
Documentation has been spotty on this subject, because the term 5k indicates that all 5000 series switches will support extended FEX's which is not the case only the 55xx will support more than 12 FEX. Maybe in the future the terminology for the 5k series should be term 5000 series and 5500 series Nexus, there are several differences and advancements between the two series.

Ask the Expert: Basic Introduction and Troubleshooting on Cisco Nexus 7000 NX-OS Virtual Device Context

With Vignesh R. P.
Welcome to the Cisco Support Community Ask the Expert conversation.This is an opportunity to learn and ask questions of Cisco expert Vignesh R. P. about the Cisco® Nexus 7000 Series Switches and support for the Cisco NX-OS Software platform .
The Cisco® Nexus 7000 Series Switches introduce support for the Cisco NX-OS Software platform, a new class of operating system designed for data centers. Based on the Cisco MDS 9000 SAN-OS platform, Cisco NX-OS introduces support for virtual device contexts (VDCs), which allows the switches to be virtualized at the device level. Each configured VDC presents itself as a unique device to connected users within the framework of that physical switch. The VDC runs as a separate logical entity within the switch, maintaining its own unique set of running software processes, having its own configuration, and being managed by a separate administrator.
Vignesh R. P. is a customer support engineer in the Cisco High Touch Technical Support center in Bangalore, India, supporting Cisco's major service provider customers in routing and MPLS technologies. His areas of expertise include routing, switching, and MPLS. Previously at Cisco he worked as a network consulting engineer for enterprise customers. He has been in the networking industry for 8 years and holds CCIE certification in the Routing & Switching and Service Provider tracks.

if i have a an F2 card 10G and another F2 card 1G and i want to creat 3 VDC'S
VDC1=DC-Core
VDC2=Aggregation
VDC3=Campus core
do we need to add a link between the different VDC's

Just to further clarify, we have 4 5548UP switches in the same management vlan. 2 switches are in one location lets say location A and they are CFS peers and are working fine.
These two switches which are having problem are in location B. All the switches are in the same vlan. Essentially the all CFS multicast messages will be seen by all 5548 switches as they are in the same vlan. I am assuming that this might not create any problems as we specify the peers in the respective configurations. Or do we have to change the CFSoIPv4 multicast addresses in location B or may be configure a different region.
Regards.

Right now there is only a few features that are not supported on N1Kv on Hyper-V
They are VXLAN and QOS Fair Weighted Queuing. We are currently demoing VXLAN functionality at Microsoft TechEd Conference this week in New Orleans. So VXLAN support should be coming soon. I can't give you a specific timeline.
For Fair Weighted Queuing I'm not sure. In the VMware world we take advantage of NETIOC infrastructure. In the MS world they do not have a NETIOC infrastructure that we can use to create a similar feature.
Code base parity (as in VMware and Hyper-V VSMs running NXOS 5.x) will happen with the next major N1KV release for ESX.
Let me know if that doesn't answer your question.
thanks
