• Fails to PI 2.0 Configuration Archive Cisco Nexus 5000

  Hello

  We have recently improved Cisco IP from 1.3 to 2.0 and I thought that this problem would be resolved, but he did not. I added two switches 5548 Nexus I can monitor and configure via Cisco first but I am not able to read the boot och running configuration to the Configuration Archive. When I start work, I get the following error:

  "device fig: java.net.SocketTimeoutException: Read timed out".

  Current NXOS: 5.2 (1) N1(2a)

  Before troubleshooting I would just answer if it should be possible to archive the Nexus to Cisco configs first Infrastructure?

  See you soon! Mattias Andersson

  Yes, I do it with success on a couple of first 2.0 facilities. My case later included NX - OS - 5548UP and 5596UP 5.2 (1) N1 (4) running and 6.0 (2) N2(1b).

• Connectivity HP C7000 and Nexus 5000

  We spend our ESX servers in a rack mount environment at C7000 enclosures with blades. Can someone talk about compatibility box blade HP and Nexus 5000? The little that I find seems to suggest that this match may not be 100% ready for primetime.

  I have a HP Virtual Connect modules or exactly what FCoE lokks like with HP blades. Does anyone have more information on this specific vegetables or aware of this configuration, used successfully?

  There is full compatibility between the HP 7000 and the Cisco Nexus 5000.

  What you need to make sure if it is that you are up-to-date with all HP firmware and drivers Nic ESX.

  Take a look on my blog that goes into this in detail:

• Nexus 5000 native FC disk array and tape library

  Is it possible to have servers to connect by FCoE to nexus 5000 switches as well as native berries FC of attached disk and tape library without requiring additional CF as the MDS 9000 switch? The reason why I ask, is that all the patterns I've seen on consolidated IO to this point show switches connected to the FC ports native on the nexus 5000 MDS. I thought that the Nexus 5000 would be able to replace the MDS attaching devices FCoE and native Fibre Channel devices. You see only such a diagram has me second guessing my initial thought.

  Yes, you can use FCoE and FC of Nexus 5000 to connect to networks. I tested and it works very well without any problems.

  FCoE, you have module FCoE in the bays and the appropriate license.

• Cisco Nexus 3548/3524 SNMP Interface traffic problem

  Hi all!

  I would like to share with you the problem I've encountered SNMP interface respect tracking on the Cisco Nexus 3500 of traffic devices.

  We is transferring our network infrastructure in the Nexus and we encountered a problem with the interface bitrate of tracking traffic on Nexus 3548: deltas SNMP counter ifHCInOctets and ifHCOutOctets show no valid data.

  We have investigated this issue and figured he could be linked with the refresh rate of the meter.
  I measured, by snmpwalk, the time between simple increments the counter ifHCInOctets to Interface VLAN and it apears to about 140seconds. But for physical interfaces (Eth), the interval of interface SNMP counters are 15 seconds and with sampling frequency of the 1960s for the queries we can still observe the problems on graphs (see attached screnshot).

  We get the same results when testing the question on various physical devices (3548 Nexus) on versions of different software - including the last being.

  snmpscreenshotvlanint.jpg

  

  And for Ethernet interfaces (same NMS - ZABBIX-config):

  snmpscreenshotphint.jpg

  

  We tested a wide Huawei s6700 switches and the range of Cisco IOS devices and there is no such problems.

  The main problem is that we cannot monitor our crucial nexus, via SNMP devices (as you can see from the attached chart).  Results are the same when configure us Cacti or Zabbix to monitor Nexus devices.

  The results of this monitoring not having meritorical value or use.

  We are working on this case with Cisco TAC, and they manage to reproduce the problem in their LAB environment. But for now, they cannot provide any solution and they claim that this isn't a bug. If we get any final statement for this case, I'll post here for your information.

  I'll be more than happy if you can post ideas that help me solve the problem described.

  Thank you in advance!

  Looks like a bug to me.  His return of erroneous data.

• Is it possible to use a Linksys by Cisco Wireless - G Internet home monitoring camera with Labview

  I was wondering if it is possible to use a "Linksys by Cisco Wireless - G Internet home monitoring Camera" with Labview

  http://www.dabs.com/ProductView.aspx?quicklinx=53PX&SearchType=1&searchTerms=network+cameras&PageMod...

  I wan't to be able to get the raw data from the camera and analyze it.

  I found a simple soloution to this problem,

  Is possible to use a web browsers invoke node basically give a screenshot of the web page (get image)

  It can then be loaded into a display of the image and will show exactly what the web browser is showing and can also be analised by unflattening the pixmap.

  Maybe it's not the most effective method, but he turns my rig fast enough and does the job

  It may also be a setting value of the display of the photo to "smooth updates" that gets rid flashes white as the changes to the image, if anyone else has this problem.

• Cisco Nexus to use authentication Radius AAA using Microsoft 2008 NPS

  I have a Nexus 7010 running

  I was wondering if you can help me with something. I'm having a problem with the approval of the order through our aaa config. We have not an authentication problem of command approval that does not work. From what I've seen and read Nexus NX - OS 6.x has not all orders for the aaa authorization, unless you configure GANYMEDE +. My basic config is below if you can help would be much appreciated.

  > ip source interface mgmt radius 0

  > key RADIUS-server XXXXX

  > host X.X.X.X key radius server authentication XXXXX accountant

  > RADIUS-server host X.X.X.X XXXXX key authentication accountant aaa

  > authentication login default group aaa authentication Radius_Group

  > RADIUS server logon group console local aaa Radius_Group

  > server X.X.X.X

  > server X.X.X.X

  > mgmt0 interface-source

  Also nobody how to configure Microsoft 2008 NPS as Raduis server to work with Nexus? I read a few post that suggests to change the

  Shell: roles = "vdc-admin" in the value field of the attribute in the RADIUS server

  Anyone know if it works?

  Thank you

  I haven't used NPS before but sounds like you are on the right track. As Ed mentioned in his post, GBA, you can set the type of protocols that you will accept during an authentication session. Authentication Nexus sessions is considered as PAP/ASCII, so you should be good to go. I don't have a Nexus switch to test with, but if you can use wireshark to capture the session and see the exact protocol / method used. However, I am sure that PAP is the way to go:

• If I want to use an external monitor of ranking on dell precision 5000 or Hp zbook (equipped both of usb3 and thunderbolt 3) this piece of harware would work with SG?

  If I want to use an external monitor of ranking on dell precision 5000 or Hp zbook (equipped both of usb3 and thunderbolt 3) this piece of harware would work with SG? My monitor is a scientist of Flanders HDSDI LM-2460W. I know blackmagic has a few options but the last time I checked, he has not worked with SG. Anyone know?

  I think Sg works more easily with an output of your video card... I run two monitors style DVI outputs, but he could use the HDMI connections too I think. The tab Setup (wrench) go you and activate a second monitor and... it's a unique method instead... use the lines where she asks location information to 'say' Sg where the upper-left pixel of your second monitor (program or viewing) is your monitor 'system '.

  I had two 1920 x 1080 monitors, stacked vertically, OS/UI on the bottom, "programs" or reading on the upper monitor.

  So, this upper-left pixel of my 2nd monitor is a negative number for 'up' and zero to indicate the two pixels top left "even".

  It is-1080 for the "vertical" number... it's the height of my 2nd screen and it is negative, because it is above the main screen.

  It is 0 for the horizontal number. Yes, they are stacked.

  Now, if I had a monitor/program play to the left of my OS/UI screen, it would be...

  Vertical number 0, as relatively, they have the same 'height ';

  Horizontal number of-1920, that reading is on the left.

  Reading right... Vertical would be 0 and horizontal a positive number of 1920 (width of the primary monitor).

  -This behavior is visible on the two 5Ks

  -J' have tried to use a different set of ports, SFP and fiber cabling without result changed

  -I can't understand this behavior?  In this, why to configure the port would cause the link to go down?

  -If anyone has experience this before, or could shed some light on this problem, it would be appreciated.

  Hello

  If you have configured ports such as access to VLANs ports, who are either:

  (a) not configured on the switch / present in the database for vlan.

  or

  (b) present in the database, but it is in a suspended state.

  You will encounter this problem.  Please can you check the status of the VLAN?

  Hope this helps

• Spotlight uses SNMP?

  Hello

  We have projector beam; Spotlight on messaging worm. 7.5 & spotlight on Windows version 3.82.

  I'm new to the spotlight.  I was ask by management if Spotlight uses SNMP if so which version of the SNMP protocol?  I don't see Windows SNMP service running so I don't think it's using SNMP, but I need to be certain.

  If Spotlight does not use the Protocol SNMP uses this Protocol for monitoring and if I could have a link to read about how followed and trap works in Spotlight?

  Thank you

• 40g of Cisco Nexus-FET

  I'm trying to choose the right cable to connect to a Cisco Nexus 40 G - FET (on a Nexus 6004). I saw on Cisco's Web site that says the FET transceiver has 12 fibres inside. Yet, when he broke out to connect to four FETs of 10G on a FEX (2232TM-E), only 8 fibers would be used.

  so... What type of connector DFO buy? A 12 FTU fiber or fiber 8 FTU? Are they interchangeable? I might as well use an 8 or a connector DFO 12 fiber on my fan-out cable?

  Cisco uses 8 fiber lit even if standard DFO is of 12 fibers. Please refer to Figure 23 here.

  As described further down in this document (figures 25 and 26) some (cited Corning) providers offer only fiber 8 DFO and which can be used for interconnection as well.

• groups of IP addresses are supported on Nexus-5000 and models down?

  Looking online, I see the ip address of the object-group is explicitly listed as

  supprted on Nexus 7000 but on other model documents command is confusing.

  For example, for Nexus-5000 references to IP address source/destination to refuse the order group objects exist in the documentation older versions of NX - OS 4.0 and 4.1 (with no explicit object-group command is listed in the same CLI reference) but in v5.x current source/destination shows no Group of IP addresses as available choice.

  Can one with access to the Nexus 5000 or 3000 check if the ip address of the object-group is an order valid on this platform?

  It seems full support (like on IOS), using the IP address groups was established in v6 NX - OS (which only works on platform 7000).

  There was also presented on the lower models?

  Thank you.

• How to create a static ARP using SNMP?

  Hello

  I want to create a static ARP using SNMP.

  I can delete an ARP by setting oid ' 1.3.6.1.2.1.4.22.1.4' to '2'.

  But none of

  '1.3.6.1.2.1.4.22.1.1 '.

  '1.3.6.1.2.1.4.22.1.2 '.

  '1.3.6.1.2.1.4.22.1.3 '.

  '1.3.6.1.2.1.4.22.1.4 '.

  can be modified or created

  SNMP-server community is RW

  I can change the other oid, for example 'type sysName' oid 1.3.6.1.2.1.1.5.0

  I used this command to create a new ARP:

  set SNMP v2 192.168.10.1 private oid 1.3.6.1.2.1.4.22.1.1 integer 1

  the answer:

  SNMP response: reqid 16, errstat 11, erridx 1

  ipNetToMediaEntry.1 = 1

  errstat 11 is NOCREATION

  And I used the tool "Mib Browser" to set a static ARP.

  the answer is NOCREATION too.

  I searched a lot of time, a lot of people have this problem,

  someone said the oid ipNetToPhysicalPhysAddress or inetCidrRouteTable is alternative,

  but our switch do not have these oids.

  I can't find a solution.

  I want to know if the task can be performed.

  Help, please.

  Concerning

  Dear Fu

  Thank you to reach small business support community.

  I'm not positive, that this can be done on small business goes, however, what is your version of the model and the firmware of the switch so I can continue the investigation.

  I'll be looking forward to your reply.

• Nexus 5000 operating as a standalone FibreChannel Switch

  Hello world

  Does anyone know if the Nexus 5000 can be used as a standalone FibreChannel Switch? Which means I don't want to run NPV on this and connect it up to a MDS or a different type of switch FibreChannel. I'm looking to create a 'Pod' scenario. Where a few servers and a storage Bay would hang the 5K on a login F_Ports is local FLOGI DB and be able to use zoning and traffic went immediately from the 5K, etc etc? I know that 5 K is not a full blown fibre channel switch such that it has some limitations, but again I think to a "Pod" as scenario.

  If the script above won't work for some reason any using CF can achieve us with FCoE CNAs on servers & storage Bay?

  Finally, FC domain IDS how 5 K can cause?

  Sorry for the questions. I'm new to SAN switching at this stage.

  Thank you all!

  Yes, it works even FC code NX - OS like a switch MDS switch.

  You connect FC HBAS, ports SAN or FCoE CNAs to Nexus.

  However, you need to license storage.
