Issue/Introduction

SNMP discovery (via UMP) done for the following devices, but "Query Discovery Server" in snmpcollector probe does not create 2 profiles for both devices.

IP Address Name
192.168.0.101 cisco1
192.168.0.102 cisco1




Cause

Discovery name (in this senario, Sysname) is duplicated for those devices.
If DNS resolution for device is not available, snmpcollector will use Sysname for profile name.
In snmpcollector probe, profile name must be unique.
Since snmpcollector probe can't create 2 profiles with the same name, it does not import both.

Environment

snmpcollector probe any version.

Resolution

Add unique entry for these devices using local hosts file (Windows : Windows\System32\drivers\etc\hosts, Linux : /etc/hosts)
on the box where discovery_agent probe (for SNMP device discovery) is running.
For example, add the following entry to local hosts.

192.168.0.101     device_primary
192.168.0.102     device_secondary

Run SNMP discovery for those devices one more time, then device name in UMP will be reflected accordingly.
Once device name in UMP become unique, run Query Discovery Server in snmpcollector again.
