When I run my playbook, the task for GET LLDP NEIGHBORS fails and it seems to be because the SNMP task does not return the proper version. The switch is an Aruba 3810M running KB.16.04.0009 soon to be running KB.16.05.0007.

Troubleshooting: I have tested with Cisco and had (not in uploaded files) been calling a variable from the group_vars to call the correct version of "show lldp neighbors" (even though the present file shows a cdp command).

Thanks in advance! I don't know if you plan on keeping this up-to-date, but it has been an asset to us thus far.

Any thoughts as to why the version info returned would be UNKNOWN?

Main output:

I was testing snmp_device_version.py with python3 on Ansible and it would throw this error:

After changing the code in lines 157 and 163 to update to python3 syntax, it fixed the issue.

Python2 syntax:

try:
        dev = SnmpHandler(**nelsnmp_args)
    except Exception, err:
        module.fail_json(msg=str(err))

    hostinfo = HostInfo(dev)
    try:
        hostinfo.get_version()
    except Exception, err:
        module.fail_json(msg=str(err))

Python3 syntax:

try:
        dev = SnmpHandler(**nelsnmp_args)
    except Exception as err:
        module.fail_json(msg=str(err))

    hostinfo = HostInfo(dev)
    try:
        hostinfo.get_version()
    except Exception as err:
        module.fail_json(msg=str(err))

Hi ,

When I run the following code I get no data back from the device. When I run the module using Ansible I do get data back. Can you help explain that ?

from nelsnmp.snmp import SnmpHandler
from nelsnmp.hostinfo.device import HostInfo

def main():

try:
    dev = SnmpHandler(host='1.1.1.1', community='xxxxx', version='2c')
    hostinfo = HostInfo(dev)

    print "trying..."
    print hostinfo.get_version()
except Exception as err:
    print "Must be a timeout or something", err

main()
