  1. Hi Greg,

    I don’t think Observium supports SNMP traps right now, only polling. I installed it a few months ago so not sure if they implemented it by now.

  2. Hi Sims,

    Once you have access through SNMP, you will have access to the entire Management Information Base (MIB).

    With views, it’s possible to limit this to certain (sub)trees.

    Cisco has some good examples here:

    https://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-protocol-snmp/20370-snmpsecurity-20370.html

    Like this one:

    snmp-server view myview mib-2 included
    snmp-server view myview atEntry excluded
    snmp-server view myview cisco included
    

    It includes access to the MIB-II and Cisco MIB but denies access to the atEntry MIB.

    Once you have Observium up and running, the only thing you need to do is to use the cloud icon in GNS3 to connect a physical network card (or a virtual one if you use vmware) to your GNS3 routers:

    This is an older video but it’s probably still 99% the same on the latest GNS3 version.

  5. Hello Justin

    When you specify the security level in the following command

    R1(config)#snmp-server group MYGROUP v3 priv

    you are specifying that SNMP packets will be authenticated and encrypted.

    When issuing the command:

    R1(config)#snmp-server user MYUSER MYGROUP v3 auth md5 MYPASS123 priv aes 128 MYKEY123

    you are specifying that the user will indeed use the User Based Security Model (USM) for SNMPv3 that has been configured in the previous command. The priv keyword in the second command is not the same as that in the first. In the first, you have the option of
