Nexus 5548 not responding to snmp

I've got a Nexus 5548 running 6.0(2)N2(3).  It does not use the mgmt interface or management vrf.  It's using a vlan interface for all my management access.
I have a simple snmp config set up:
snmp-server community mystring
My SNMP server is directly connected (no firewalls, no acls).  I can ping my nexus from the SNMP host, but can't get SNMP replies.
I've done an SNMP debug, nothing happens when I run an snmpwalk.  I also checked show snmp, and it's showing no SNMP input packets.  
Could this have something to do with trying to use the management vrf?  Or something simple I'm missing?  
Thanks

Ha wow -- "sh run snmp" pointed me to the problem. There was a command:
no snmp-server protocol enable
That must be a default, I never entered that.  Anyway a 'snmp-server protocol enable' fixed it.  I should have caught that.  Although an hour with TAC also didn't notice it hehe.
Thanks!

  • WLC is not responding to SNMP requests.

    Customer is using a 4400 WLC.
    He has a management tool that works using the SNMP logs from the controller, he can ping the

    WLC doesn't reply.
    The SNMP server IP address is 192.168.122.11 and the WLC's IP address is  10.20.1.31.

    I have also a packet capture taken from the same switchport, I attach it here.
    What could be the reason for not responding?

    You need to add the management tool in the WLC as a trap reciever.

  • Cisco ASA Not Responding to SNMP

    Hi All,
    I have a Cisco ASA that I am trying to discover with SNMP (Solar Winds). The Solarwinds server can ping the ASA on the E1 interface (on the same network as the server), yet it cannot be discovered using SNMP, it fails every time.
    This is the config I have for the ASA.
    interface GigabitEthernet0/0.224
    description NMS
    vlan 224
    nameif NMS
    security-level 100
    ip address 10.11.120.225 255.255.255.240
    snmp-server host NMS 10.11.120.235 community *****
    no snmp-server location
    no snmp-server contact
    snmp-server community *****
    snmp-server enable traps snmp authentication linkup linkdown coldstart
    The server trying to discover the ASA is 10.11.120.235 and the community string is public.
    Also, I do not know how you add a RW string to a Cisco ASA - it seems to only let you add a single string.
    Thanks in advance.
    Dan

    Hi Daniel,
    The ASA supports only SNMP read-only access. SNMP write access is not allowed, so you cannot make changes with SNMP.
    Have you tried to manualy pool the ASA using snmpget or some other tools. One issue might be the community used by Solarwinds.
    Regards
    Dan

  • Network device is not responding to SNMP

    Hello All
    We are monitoring our first network device (Cisco  FW) SNMP V2.
    We discovered it and were able to collect performance counters for 2 hours.
    After that, only thing we can collect is ICMP response. Also it keeps switching between healthy and warning state.

    Hi Helpful guy,
    This problem occurs on some network devices in case that the maximum number (default 50) of OIDs that OM will query per batch is too high. You probably find a entry in the Cisco logs:
    "incoming SNMP request (# bytes) from IP address
    IP_ADDRESS and PORT
    PORT_NUMBER Interface "inside" exceeds data buffer size, discarding the SNMP request"
    This problem can be solved by creating a registry key:
    location: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Modules\Global\SNMP]
    key type: DWORD value
    key name: MaxOidsPerRequest
    default: 50
    Change the default value to one that suits your environment.
    Hope this helps,
    Regards Marthijn van Rheenen
    Blog: Heading To The Cloud’s
    I'm using OpsMgr 2012 R2.  I started with MaxOidsPerRequest set to 30 and monitoring was going well for two ASA 5510s.  I have raised the number to 40 and am waiting to see if there are any issues.  It is a decimal value and I set it on both
    management servers in the resource pool for network devices.

  • RSC Cards responding to SNMP?

    I have several V880s with the RSC cards configured for remote access.
    Recently, our security group contacted me and asked me to either turn
    off SNMP or change the Public value. To which I responded "Huh?!
    SNMP is not even running". (It's not)
    Apparently, the IP address bound to the RSC card is responding to SNMP
    requests. I checked all the variables with "rscadm show" and I dont
    even SEE snmp anywhere, so I am at a loss.
    Does anyone know:
    a) Why the Sun RSC cards would respond to SNMP?
    b) How I make them NOT respond to SNMP?

    7 views and nobody has any idea?
    :(

  • SNMP not responding

    Hi,
    I have a Windows 2003 R2 server with SNMP enabled.
    I monitor it via Nagios, and have been working fine since a few days ago, that snmp started to not answering.
    I've removed SNMP services, and reinstalled, clean registry entries, but unsuccedfully.
    What I see strange is that when I type "netstat -an | find "161"" , I got:
    UDP    0.0.0.0:161            *:*
    UDP    x.x.x.x:161      *:* (where x.x.x.x is the IP address assinged to the network card).
    The rest of servers only show:
    UDP    0.0.0.0:161            *:*
    I think this could be the cause, but don't know how to solve it.
    There is no firewall.
    Thanks,

  • UCS FI 6248 to Nexus 5548 San port-channel - not working

    Hi all,
    I'm sure I am missing something fairly obvious and stupid but I need several sets of eyes and help.
    Here is the scenario:
    I want to be able to create san port-channels between the FI and Nexus.  I don't need to trunk yet as I can't even get the channel to come up.
    UCS FI 6248:

    Nexus 5548

  • Cisco nexus 7706 Module x not responding... resetting

    The EOBC is Ethernet Out of Band Channel.  
    There are regular keepalives or 'heartbeats' going between the sup and line cards.  The error messages you received indicate a heartbeat went missing between SUP and linecard. 
    If a single heartbeat went missing, it will be corrected automatically, however if multiple heartbeats are lost simultaneously then the line card would be reset (sup would power off and power on that slot in attempt to resolve a diagnostic issue).
    So if the card is stable after that you can consider this as a one time (transient) issue.
    You can also check EOBC stats to see if any error increasing.

    show hardware internal eobcsw stats
    show hardware internal cpu-mac eobc stats

    Hope this helps.

  • NTP Nexus 5548s

    I know that with the Nexus switches that we must use the management port and the management vrf for services such as NTP, SNMP etc. I have this configured on my 5548 and it still will not sync with NTP.
    ntp server 10.1.0.63 prefer use-vrf management
    ntp server 10.1.0.65 use-vrf management
    ntp peer 10.100.4.156 use-vrf management
    ntp source 10.100.4.155
    I verified connectivity to the NTP server by pinging it:
    5548-A# ping 10.1.0.63 vrf management
    PING 10.1.0.63 (10.1.0.63): 56 data bytes
    64 bytes from 10.1.0.63: icmp_seq=0 ttl=126 time=1.095 ms
    64 bytes from 10.1.0.63: icmp_seq=1 ttl=126 time=0.657 ms
    64 bytes from 10.1.0.63: icmp_seq=2 ttl=126 time=1.242 ms
    64 bytes from 10.1.0.63: icmp_seq=3 ttl=126 time=0.783 ms
    64 bytes from 10.1.0.63: icmp_seq=4 ttl=126 time=0.735 ms
    Maybe it is working and I dont know it. When I run "show ntp status", I get this
    5548-A# show ntp status
    Distribution : Enabled
    Last operational state: Commit operation successful
    5548-A#
    5548-A#

      10.1.0.63                     Server (configured)
      10.1.0.65                     Server (configured)
    5548-A#
    i am used to seeing a different output from show ntp status. It is not telling me that it is synchronized. Please tell me what I am missing here.
    Bruce

    Hi Bruce,
    This looks good. I admit NTP isn't as easy to verify on NX-OS as it is on IOS, this indeed causes confusion.
    In your case you see the * for 10.1.0.63, so the device is synched to this source. You can verify with:
    # show ntp statistics peer ipaddr x.x.x.x
    with the above IP.
    Here is a brief explanation:
    * - selected for sync
    Device is synchronized to this source
    + -  peer mode(active)
    The mode in which a host has configured itself to poll a time server
    that it might synchronize with. In this mode, the host also allows
    itself to be polled by that time server.
    - - peer mode(passive)
    The mode in which a time server is polled by a host that has configured
    itself in ``symmetric active mode''. In this mode, the time server can
    also poll that host.
    = - polled in client mode
    The mode in which a host polls a time server that it might synchronize
    with, but it will not respond to polls from that time server.
    I hope the above helps, but this looks as if you are up and running at this point.
    Thanks,

    Well, it wasn't a DNS issue, it was a routing issue that affected ISP customers in half of the country. https://community.shaw.ca/thread/9284?start=0&tstart=0
    I can confirm that iTunes will now open and is functional. It seems that if the application can't access some internet resource immediately when it launches it will immediately lock up and never come back! No offline mode??!?!

  • Nexus 5548 Layer 3 daughter card insertion

    Hello there,
    I am planning to install Nexus 5548 Layer 3 daughter card. I found the hardware removal procedure on Cisco website but it doesn't say whether it's hot plugged or not. (Since I've to remove existing L2 module so I guess the box needs to be powered off but not sure). Has anybody had the experience in doing the upgrade to share?
    Thanks in advance

    I ended up getting the answer from TAC. First put in these two commands:
    test ethpm l3 enable-show-iport
    test port-channel l3 enable-show-ipc
    Then you will get some new port channels showing up (127 and 128).
    I'm not sure what 128 is for, but 127 is the internal port channel for the L3 card. Then you can view stats and poll with SNMP against the interface...
    show interface port-channel 127

  • To be unable to discover a Nexus 5548 wirth DCNM 5.2(2e)

    Hello,
    I am unable to discover 2 Nexus 5548 with the SAN client of DCNM 5.2(2e)
    These Nexus are used like LAN and SAN switch. Each Nexus is a SAN fabric. I would want to use DCNM in order to configurate the zone/zoneset via GUI. These Nexus 5548 run 5.1(3)N2(1b) release.
    The Nexus ARE NOT managed  via the Mgmt interface (OOB) but they are managed via an interface vlan (InB)
    I could not configure rightly
    - the snmp-server user (SNMP user V1/v2 or V3 + group ? )  CLI on Nx
    - to configure the discovery in order that DCNM discover each fabric either from web GU interface or java SAN client
    Please help !

    I believe DCNM requires an ssh login to the Nexus and not SNMP.
    DCNM uses Netconf over SSH protocol. See this earlier posting.

  • 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.

  • Prime Infrastructure 2.0 and Nexus 5548, SSH credentials fail

    Hi,
    I'm having problem getting the Prime Infrastructure 2.0 to login with SSH to a Nexus 5548 to do an inventory. I get "Wrong Telnet/SSH credentials". But when I use the same credentials from another SSH-client it works fine. I also tested to SSH from the console of the Prime-server and that also works fine.
    Any ideas???
    Regards,
    Stefan Lindkvist

    I have PI 2.0 working against Nexus 5k's in two different installations. See below for an example (click to enlarge).
    Have you put in an entry in both the login and enable fields (even though they are not separately required when logging in directly)?
