Device discovery problem using snmpv1

  • 1.  Device discovery problem using snmpv1

    Posted Aug 29, 2013 01:54 PM

    Hi guys,

     

    I'm trying to discover other vendor wired switches with Airwave 7.7.3. The devices are 3com 4200 or 3com 4500 families with snmpv1 capabilities only. I run several Scans with different set ups on  Device Setup > Discover and Device Setup > Communication, while monitoring Airwave interface with tcpdump. The best result I got is snmpv1 request and response with no new device discovered.

     

    I also tried manually addition on Device Setup > Add and got snmpv2 request only.

     

    The command "snmpwalk -c community -v 1 ipaddress" on Airwave console works properly.

     

    Any other ideas?

    João,

     

    I don't think we support discovery of those devices with scans.  I think your best bet would be to import them via csv on the Device Setup -> Add page.

    Dan,

     

    If manual addition is not working for one device I don't see why it would work for many devices in a csv file. The problem is: Airwave uses snmpv2 by default to contact an added device. Device speakes snmpv1 only. I haven't found a way to change snmp version to snmpv1 on Communication properties of device.

    Hi,

     

    According to this http://www.andovercg.com/datasheets/3com-4500g-switches.pdf

    it should support snmp v2.

     

    Are you on the latest firmware on that switch?

     

    EDIT

    Edited the link, had the 4400 instead of 4500
