Issue/Introduction

As a precaution before upgrading, we would recommend to make a backup copy of your SNMPv3 strings.  This is a very simple process that could save a lot of time afterwards if there is an issue after the upgrade with the SNMPv3 strings.

Environment

DX NetOps Spectrum all currently supported releases

Cause

Unlikely, but possible corruption to happen during an upgrade

Resolution

There are two methods that you can use to do this.

Method 1  Use the Modeling Gateway to Export the Security Srings

Link to Modeling Gateway method

 

Method 2 Use CLI to dump the SNMPv3 strings

The commands (in blue, output in green) are run from the VNM shell (vnmsh) command line, accessed by:

cd $SPECROOT/vnmsh

Then running ./connect

  1. First get the model handle in CLI of the GlobalConfig model by running 

    $ ./show models | grep -i GlobalConfig
    0x100012    GlobalConfig                      0x10470     GlobalConfig


  2. Get the SNMPv3 raw attribute values (attribute 0x13388)

    $ ./show attributes mh=0x100012 | grep -i SNMPv3Profiles
    0x12bd4     oldSNMPv3Profiles
    0x13388     SNMPv3Profiles                                         5A.CE.C0.E4.A.BE.A8.8B.A2.56.A.42.C3.E1.47.6B.89.4E.97.96.3F.FF.57.94.5E.12.7F.37.FB.C0.64.E0.BD.C6.C4.5F.3F.55.3D.2E.D.D7.C.81.27.E4.E6.44.D.98.7D.BD.17.33.DB.99.B5.C5.94.FC.79.2F.31.F.D9.3C.5.98.80.7F.DC.B4.C.15.F3.7C.B9.B0.F5.D9.6.8C.DA.67.EE.F8.A3.AC.90.D.9D.48.FE.89.1F.45


  3. In the above example, the raw values are listed in AlphaNumeric characters. These should be saved all together on the same line in case you need to reimport them.


  4. If you want to remove your SNMPv3 profiles you can do this by the following command

    ./update mh=0x100012 attr=0x13388,val="0"

    NOTE: For further details on the ./update command, reference the online guide - TechDocs : DX NetOps Spectrum 25.4 : update - Updates Model and Model Attributes

  5. If your values are blank after an upgrade and you need to add them back you can take the values on a single line and reimport them with

    ./update mh=0x100012 attr=0x13388,val="5A.CE.C0.E4.A.BE.A8.8B.A2.56.A.42.C3.E1.47.6B.89.4E.97.96.3F.FF.57.94.5E.12.7F.37.FB.C0.64.E0.BD.C6.C4.5F.3F.55.3D.2E.D.D7.C.81.27.E4.E6.44.D.98.7D.BD.17.33.DB.99.B5.C5.94.FC.79.2F.31.F.D9.3C.5.98.80.7F.DC.B4.C.15.F3.7C.B9.B0.F5.D9.6.8C.DA.67.EE.F8.A3.AC.90.D.9D.48.FE.89.1F.45"


  6. Verify they are good by running the same command again

    $ ./show attributes mh=0x100012 | grep -i SNMPv3Profiles                          
    0x12bd4     oldSNMPv3Profiles
    0x13388     SNMPv3Profiles                                         5A.CE.C0.E4.A.BE.A8.8B.A2.56.A.42.C3.E1.47.6B.89.4E.97.96.3F.FF.57.94.5E.12.7F.37.FB.C0.64.E0.BD.C6.C4.5F.3F.55.3D.2E.D.D7.C.81.27.E4.E6.44.D.98.7D.BD.17.33.DB.99.B5.C5.94.FC.79.2F.31.F.D9.3C.5.98.80.7F.DC.B4.C.15.F3.7C.B9.B0.F5.D9.6.8C.DA.67.EE.F8.A3.AC.90.D.9D.48.FE.89.1F.45
