Unable to get a device to use the High Speed Interface vendor certification even when all OIDs are available

Issue/Introduction

We are looking at a device and its interface information and seeing gaps in the chart data.

When the Data Collector requests a SNMP GET-NEXT for 1.3.6.1.2.1.31.1.1.16, 1.3.6.1.2.1.31.1.1.1.14 returns as the next result

Environment

Performance Management

Cause

This is due to the device being set to use SNMPv1 and one of the limitations for SNMPv1 is the inability to work with 64bit items.

Resolution

Access the device in Monitored Devices and change the SNMP-GET version from SNMPv1 to SNMPv2c.  Then either prompt an Interface metric family update or wait for change detection to occur the following morning.

Additional Information

You can get a list of SNMPv1 devices via rest

URL: http(s)://<DA>:<PORT>/rest/devices/manageable/filtered

Port is usually 8581 (http) or 8582 (https)

Method: POST
Content-Type: "application/xml" 
Body: 

<FilterSelect xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="filter.xsd">
    <Filter>
        <ManageableDevice.SNMPProfileVersion type="EQUAL">SNMPV1</ManageableDevice.SNMPProfileVersion>
    </Filter>
 <Select use="exclude" isa="exclude">
        <Item use="exclude">
            <Name use="include"/>
        </Item>
        <ManageableDevice>
          <SNMPProfileVersion use="include"/>
         </ManageableDevice>  
    </Select>
</FilterSelect>

Example output:

<ManageableDeviceList>
    <ManageableDevice version="1.0.0">
        <ID>123456</ID>
        <SNMPProfileVersion>SNMPV1</SNMPProfileVersion>
        <Item version="1.0.0">
            <Name>deviceName</Name>
        </Item>
    </ManageableDevice>
</ManageableDeviceList>

REST can also be used to convert devices to SNMPv2c
