LMS 4.2 with Nexus C7010 Switch

Hi Guys,
I tried to add Nexus C7010 into my LMS 4.2, the SNMP work like charm but not for the archieve config.
It just show "Incorrect" under SSH, further checking I found this
"Failed to establish SSH connection to 10.152.xx.xx - Cause: Authentication  failed on device 3 times."
I understand that Nexus is using Role-Based Account and there is no enable secret password anymore.
How do I add the Credential for Nexus? Other devices with IOS is no problem at all.
Please Help... Thank you.

Pls try this...
There is a legacy Button on top right corner, select DFM, then select Event sets and select the required triggering fields like flap, operationallydown etc... and make it as A (there is a tick mark available to group all these fields under 'A' group.
Secondly, go to email notification group and select all the devices which you want to monitor and select Alerts and over there select 'A', then select Critical, Warning etc, click next next...
For rest of it, pls go by the logic.

  • Very low transfer speed issue on SUN4270 M2 server connected with nexus 5548 switch on 10GB fiber.

                       Hi,
    I have 2 SUN 4270 M2 servers connected with Nexus 5548 switch over 10Gb fiber card. I am getting performance of just 60 MB per second while transfer of 5Gb file across 2 servers. The similar speed i use to get on 1Gb network also. Please suggest how to improve the tranfer speed. On servers, ports ET4 and ETH5 are bonded in bond0 with mode=1. The server envrionment will be used for OVS 2.2.2.
    Below are the details of network configuration on server. I quick help will be highly appriciated--

    Hi,
    Thanks for reply..but the RX errors count is keep on increasing and the transfer speed between 2 servers are max 60MB/ps on 10GB FC card. Even on storage also, i am getting the same speed when i try to transfer data from server to storage on 10GB FC card. Servers and storage are connected through Nexus 5548 switch.

  • LMS 3.2: RME failed archive with Nexus 5010

    Hi,
    LMS 3.2, RME 4.3.1, dev packages updated, Windows.
    We would like to archive the configuration of the Nexus 5010 switches. Due to authentication with Radius based on tokens we're not able to use telnet/SSH and therefore we only can use SNMP WRite in combination with TFTP.  But, this is not working at all. Other systems like 3750 works fine. Is there a difference between Catalysts IOS and nexus NXOS?
    I searched the forum and found this:
    https://supportforums.cisco.com/message/663481#663481
    upgrade to LMS 2.6, archive config not working anymore
    We ship and start a TFTP server by default on Windows.  You must have an SNMP read-write community string configured on your devices, and entered in DCR for TFTP config fetches to work.  Additionally, udp/69 must be open between device and server.
    The easiest way to troubleshoot this kind of problem is to start a sniffer trace on the LMS server (using Device Center > Packet Capture).  Filter on all traffic to one of the failing devices.  Then, run a Sync Archive job for that same device.  When it fails, the sniffer trace will indicate what the problem is
    Regards

    Hi Lavramov,
    Yes I'm quite sure, I installed the required packages acoording to the Nexus.RME431.v2-2.readme.pdf manual. the manual tell me to install the following (see also attachement).
    To install the Cisco Nexus Series Package, you must install the following dependent packages:
    - SharedDcmaSS.RME431.v2-2.zip
    - SharedInventoryMDS.RME431.v1-5-1.zip
    - SharedSwimMDS9000.RME431.v1-6-1.zip

  • 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.

  • Stackable switche options with Nexus range? - Nexus 3172

    Hi all,
    We are looking at upgrading our Rack switches. We have 3 racks and need about 80 10Gig copper/RJ45 server ports per rack. We are fairly price conscious.
    I am new to Nexus product range, but have a lot of experience with Catalyst switches.
    We are considering Nexus 3172T switches. But I’m not sure if they are really suitable because they don’t stack.
    I would far rather a switch model that we can stack together so I don’t need to manage each switch individually (much as you would do with Catalyst 3750). We did look at Catalyst 4500X but they are too expensive.
    Initially we only need Layer2 switches, but I would really prefer stackable switches in case we move to Layer3 switches (I don’t want to have to muck around with HSRP).
    It really seems to be a big hole in the Cisco product range. Every other vendor we have looked at has a Virtual Chassis (Juniper, HP, Brocade) system that would be idea. Cisco have VSS in the 4500x but its pretty rubbish as it only allows two switches.
    What sort of options do I have with Cisco Nexus at a reasonable price?
    Simon

    I would suggest you read this white paper which details the pros and cons of direct connect storage. 
    http://www.cisco.com/en/US/partner/prod/collateral/ps10265/ps10276/whitepaper_c11-702584.html   This paper captures all the major design points for Ethernet and FC  protocols.
    I would only add that in FlexPod we are trying to create a highly  available solution and "flexible" solution; Nexus switching helps us  deliver on both with vPC and unified ports.
    NPV equats  to end-host mode which allows the system to present all of the servers  as N ports to the external fabric.  In this mode, the vHBAs are pinned  to the egress interfaces of the fabric interconnects.  This pinning  removes the potential of loops in the SAN fabric.  Host based multipathing of the  vHBAs account for potential uplink failures.  The NPV mode (end-host  mode) simplifies the attachment of UCS into the SAN fabric and that is  why it is in NPV mode by default.
    So for your last question, I will have to put my  Product Manager hat on so bear with me.   First off there is no drawback  to enabling the NPIV feature (none that I am aware of) the Nexus 5000  platform simply offers you a choice to design and support multiple FC  initiators (N-Ports) per F-Port via NPIV.  This allows for the  integration of the FI end-host mode described above.  I  imagine being a  unfied access layer switch, the Nexus team enabled standard Fibre  Channel switching capability and features first.  The implementatin of  NPIV is a customer choice based on their specific access layer  requirements.

    I think you can post this question on routing switching section as well , experts there have better suggestion related to port channel and hsrp.

  • The meaning of Interface Ethernet250/1 under the Nexus 2000 is connected to Nexus 5000 switch

    Dear all,
       Recently, I prepared and deploy a network monitoring system to monitor the new generation Nexus connected network.  With using snmpwalk to query the interfacs information from the Nexus 5000 switch (one Nexus 2000 is connected to it via FlexLink), I found that other than normal Nexus 5000 and 2000 ports(ifName to be Ethernet1/1, Ethernet1/2, ... Ethernet190/1/1, Ethernet190/1/2...), a series of interface with ifName Ethernet250/1, Ethernet250/2, .... to be appeared in the interface SNMP tree.   With logged into the Nexus 5000 and issue display interface command, I can only found the information on the normal interfaces but not the abnormal interface Ethernet250/1, ...
       Would someone know what is it (do E250/1 is a logical interface like port channel or VLAN) and how to monitor it ?  Thanks in advances.

    I've not seen that myself. Could it perhaps be a VPC (Virtual Portchannel)?

  • SFP+ Compatibility with Nexus 3065-x

    Hi,
    I need to know if the STP-SFP+-LR Wavelenght 1310 10km  from other venders will be compatible with the Cisco Nexus 3065 switch. I know you can run
    switch(config)# service unsupported-transceiver
    switch(config)# no errdisable detect cause gbic-invalid
    My question is will it work?
    Thank you
    Etienne

    From other vendors?  No it won't.
    You can use those two hidden commands but any troubles with your 3rd party SFP+ will not be supported by TAC.
    The reason is because there have been numerous well-documented cases where the 3rd party modules (not made by the big five) is the root of (or part of) the problem.

  • FCoE using Brocade cards CNA1020 and Cisco Nexus 5548 switches

    All,
    I have the following configuration and problem that I am not sure how to fix:
    I  have three Dell R910 servers with 1TB of memory and each has two  brocade 1020 CNA cards dual port.  I am using distributed switches for  the VM network and a second distributed switch for VMotion.  I have two  of the 10G ports configured in each distributed switch using IP Hash.   The management network is configured using a standard switch with two 1G  ports.
    The  Nexus configuration is we have two nexus 5548 switch connected together  with a trunk.  We have two VPC's configured to each ESX hosts  consisting of two 10gig ports in each VPC with one port going to each  switch.  The VPC is configured for static LAG.
    What  I am seeing is that after a few hours the virtual machines will not be  accessible via network anymore.  So if you ping the VM it will not work  and if you get on the console of the VM then ping the gateway then  nothing as well but if you try to ping another virtual machine on the  same host on the same VLAN then it will work so traffic is going through  the ESX backplane.  If I reboot the ESX host then things will work  again for another few hours or so then the problem repeats.
    The version of vSphere I am using is ESXi4.1
    Please assist I am stuck.
    Thanks...

    Here is the link for Nexus and Brocade interoperability Matrix
    http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/interoperability/matrix/Matrix7.html#wp313498
    usually this table would show those models those have been tested and verified
    However I do not see  Brocade 5300 listed in the table . It could be, interoperability may have not been tested by both vendors perticularly to 5300 type Model.

    Kumar 

    Hi Chien-Hsing Wu, I just ran into this post, sorry I couldn´t reply to your original one. Since I did not see an explanation on how to get 960 Mpps, I included one for you:
    The 960 Mpps number you mentioned is calculated taking in account modules with one M1 forwarding engine, which is the case for modules such as N7K-M132XP-12, for example. Other modules use a M1 forwarding engine (some newer modules use even 2 forwarding engines).
    The "M1" indicates the forwarding engine is M Series, first generation and is capable of delivering 60 Mpps of Layer 2 and 3 IPv4 unicast or 30 Mpps of IPv6 unicast for all ports on that module.
    You can use up to 16 I/O Modules on the 7018, which brings the 16 (forwarding engines)* 60 (mpps if M1)  = 960 Mpps.
    Be aware that more recent modules use even dual M1-XL forwarding engines, delivering 120 Mpps L2 and 3 IPv4 unicast or 60 Mpps IPv6,  and others use F1 forwarding engines, delivering 480 Mpps of distributed L2 unicast per module.
    On the other hand, regarding the calculations you suggest with 230 Gbps, some documentation shows 7.8 Tbps as total switching capacity for the 7018. You get that number assuming you are using Fabric 1 modules, or Fabric modules from 1st generation. If this is the case, calculation is as follows:
         230 Gbps per slot for the I/O related slots
         115 Gbps for the supervisors
         (16 * 230) + (2 * 115) = 3910 Gbps, and taking in account full duplex transmission we multiply this by 2 and get the 7.8 Tbps.
    As mentioned by Amit Singh, if we use Fabric 2 modules each slot could *potentially* use 550 Gbps (depending on the module), which is the total crossbar bandwidth available for each slot if your chassis is equiped with 5 Fabric 2 modules, as opposed to the 230 Gbps when the fabric modules are 1st generation modules.

    So as a security cautious user when i first got to Windows 8.1 Pro 64Bit I encrypted both the C and D drive (Split the main disk) to protect myself and my family. Unfortunately that has not been very helpful with the way in which booting and running from
    either external USB devices or CD/DVD works, not allowing myself to at all.
    My usual security suit I  use is Comodo Internet Security, which additionally comes with Comodo Kill Switch. Whilst using the application instead of stopping one of the TCP connections I was meant to I accidently stopped an Windows Explorer connection.
    For some reason since then Windows Explorer, nor most windows apps or services themselves will run. For example msconfig will run but sfc /scannow or mmc will not, whether in safe mode or normal mode.
    What Caused the Problem?
    Cannot 100% say
    What I Think Caused the Problem?
    Myself running Comodo Kill Switch stopping a vital server connection with Windows Explorer that messed up alot. Or a potential Virus unknown how cannot fully scan system as wont boot externally or run many apps.

    Can run Command prompt
    Cannot run any control panel items
    Cannot run services.msc

    Cannot use Windows Installer
    What Fixes I Have Tried So Far
    Ok so like any normal user I don't want to lose my files. So here are what I have tried so far:
    Repair MBR (Repair Completed, No Luck)
    SFC /SCANNOW (Returns Error 'Windows Resource Protection could not start the repair service')
    Tried sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=c:\windows (Could not access drive)
    Fixwin2 (Will not run in either normal or safe mode)
    Booting using Windows 8.1 via USB (Cannot boot from extermal devices due to Bitlocker Encryption)
    Booting using Kali Linux Via DVD & USB (Cannot boot from external devices due to Bitlocker Encrytption)
    How do I know it is because of Bitlocker, because last time I disabled it, I could run from external devices
    Tried to run bitlocker to change settings (Will not run)
    Have used both password and recovery keys to unlock driver, they work but when applications are running on windows the drive is still locked?
    Tried windows Automatic Diagnostic and Repair (Could not repair anything, did make a log I am still to extract from the syste)
    There are No System Restore Points
    I'm sure there is much more information I could post however I will leave it on an ask to know basis, apart from the log files and further information to gather. Below is my list of trial and error fixes to try for today (need more ideas and help please!):
    Hiren's 15.2 Boot CD via DVD (NOT ABLE TO BOOT)
    Hiren's 15.2 Boot CD via USB (NOT ABLE TO BOOT)
    Research into the Bios and Possible Update in-case of implementation of Virus, can access flash utility (STILL NOT TESTED)
    Try and get a portable version or a working version of windows installer to try and re-install Comodo Internet Security (STILL NOT TESTED)
    Another way to disable Bitlocker
    Anti-Malware / Anti-Virus Scan If Possible to Run One
    Bitlocker Repair Tool, will try this also
    I have posted this as have not found much info online, usually find it and crack on but this time things are a little more tricky, my priority task I really need to do is remove the Bitlocker Encryption, but if the application will not run... what do I do
    then?
    Thanks for your time reading all, Sorry for any poor formatting or spelling.
    Update 1: MMC.exe Error Code
    Ok so now have the computer in safe mode, still same as before, no explorer.exe, no services etc... Just went into the Task Manager > Services (Tab) > Open Services (Option at bottom)
    This is the error I get:
    'The Instruction at 0x785a746c referenced memory at 0x000000a8. The memory could not be read.
    Any Ideas on what this error is and why?
    Update 2: CHKDSK Works with no Fix
    Update 3: Hiren's 15.2 Boot CD - USB Boot still no luck booting around Bitlocker Encryption
    Just to explain again, I already have unlocked the drive with correct bitlocker password or recovery key yet the drive remains locked not allowing windows refresh of files of complete install from the windows recovery menu as keeps saying drive is locked

    Ok so attempt number two to write this update via bloody phone! (Just refreshed page whilst writing!)
    Update 4:
    Problem - cannot run from bootable devices (DVD/USB)
    Cause - bitlocker fully encrypted drive stops this working
    Repair - Boot up holding F9 to enter windows recovery Input Bitlocker recovery keys to unlock drives
    Navigate to Command Prompt in advanced settings Execute following code:
    Repair-bde c: d: -rp 000111-222333-444555-etc...
    (Code found from https://technet.microsoft.com/en-us/library/ee523219%28v=ws.10%29.aspx)
    Note for those using this: It is common while unlocking certain drives to get errors such as: Quote from http://www.benjaminathawes.com/2013/03/17/resolving-partial-encryption-problems-with-bitlocker/
    "LOG INFO: 0x0000002aValid metadata at offset 8832512000 found at scan level

    (0×00000017) …followed by around 20 similar entries that differed only by the offset value"
    Repair Status for Update 4: COMPLETED - However over wrote D drive data so now need to recover that
    Problem 2 - windows services corrupted along with windows files
    Cause - Unknown
    Repair - wait until system is fully decrypted Once fully decrypted ensure boot from USB/DVD
    Re-do fixes that would not work before if this has fixed boot issue Confirm fix / update post Hope anything I put here helps others also

  • Windows XP see blank screen when remote desktop to Windows 7 with fast user switching disabled

    All computers are in workgroup environment, no AD.
    Windows 7 pro are configured with fast user switching mode disabled so that only one login session can run at a time. When a Windows 7 machine remote desktop to another Windows 7 machine, the remote desktop 'server' will give 30 seconds count-down for the
    console logged in user to accept remote connection, or when timeout expires it kicks out the console logged in user. This is completely ok.
    This become a problem when a Windows XP rd client try to remote desktop to these Windows 7 machines, Windows XP see a blank screen if the remote Windows 7 machine has a user logged in, as it is waiting for the user to log off first. This is not desirable
    as our administrators want the console session to be logged out automatically if they (administrators) want to remote desktop in.
    Is this a configuration problem? Is this a OS design, can't be changed?
    Valuable skills are not learned, learned skills aren't valuable.

    Hi,
    As I know, for RDP session in Windows 7, you don't need to configure the fast user switch option disabled. Windows 7 doesn’t support multiple Remote Desktop sessions by design, that means only one RDP session at a time.
    I remote into my Windows 7 machine (which has a user logged in) from my XP machine, all work fine, the user logged in Windows 7 machine is automatically "kicked off".
    May I ask a question? Does this issue happen in all XP machines? If you leave Windows 7 machine started and no user logged in, the RDP session in Windows XP established quickly?
    I would suggest you keep latest drivers graphic card and latest updates paches for both Windows XP (Windows XP has come to its end of the lifecycle)and Windows 7.

  • User activity with fast user switching

    what actually continues with one user when another user logs on with fast user switching?
    Does any activity continue, such as downloading, calculating, getting mail, or playing movies? Or does everything go into limbo until that user logs back on?

    Audio output is squelched when fast user switching. Under Panther, audio playing in one user account would continue to play after fast user switching to another account. Under Tiger, the actual process continues, but the sound is muted.
    Same thing goes for audio input. I learned this the hard way by setting up an app to record a two hour radio program through the built-in audio input jack. During the recording I switched to another account for an hour. When I later went to listen to the recording, there was an hour of silence corresponding to the time I was in the other account.
    I really wish Apple would fix this.

  • Problems with Nexus 7

    1. On Play store, I cannot use this app because it is not compatible with Nexus 7 (N7)??
    2. When it does eventually get fixed to work with N7, can I edit with no internet connection (N7 does not always have wireless connection)?
    TIA

    Hi,
    we now support 7 inch devices.
    The no internet connection issue that you mention, are you referring to not being able to start the application without an internet connection?
    Thanks,
