I am facing an issue in Infoblox NetMRI and would appreciate your guidance.

NetMRI Version:

7.5.4.104695

Network Setup:

  • Cisco Layer 3 switch is added and successfully discovered in NetMRI.
  • NetMRI shows all switch information (interfaces, VLANs, MAC table, ARP, SNMP, etc.).
  • A physical laptop is connected to switch port (GigabitEthernet0/30) via LAN cable.
  • SNMP is enabled on the switch and working (NetMRI can poll successfully).
  • However, the end device (laptop/host) is not visible in any of the following sections:
    • Network Explorer → End Hosts
    • Switch Port Management → Connected Hosts / MAC Table
    • Device → Interfaces → Connected End Devices

Issue:

Even though the switch is fully discovered and visible in NetMRI, the laptop/end host connected to the switch port is not being detected or displayed

 Request for Help:

Can you please guide me on:

  1. Do I need to enable any specific setting in NetMRI to collect MAC/ARP/End Host data?
  2. Is there any required Cisco configuration (e.g., IP Device Tracking, ARP timeout, port security, LLDP/CDP)?
  3. Do I need to enable Switch Port Management Polling separately for end host visibility?
