snmpcollector is not able to discover interfaces on cisco nexus

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

Created a profile for cisco nexus and using SNMPv3 for the device.

After discovery is finished, no interface components are visible in the probe GUI.
 

Environment

DX UIM 20.4.x / 23.4.x

Target device is Cisco nexus using any snmpcollector probe version

Cause

• If snmp v2 or v3 is used, we use 20 oids in a snmp bulk get request
• It caused cisco nexus to be too busy to respond to our snmp request

Resolution

1. Open snmpcollector probe in Raw Configure

2. Set the below key in the <setup> section

   MAX_BATCH=3

3. Click Apply

4. Run "Force Component Rediscovery" for Cisco nexus profile.
