The core switch has a separate IP address
Each IP address can be assigned to specified interfaces or ports, Link Aggregation Groups (LAGs), or Virtual Local Area Networks (VLANs).

Should we use fiber optic cable or Ethernet cable to connect to the core switch
In practice, fiber connects the heavy-duty infrastructure (switches, building uplinks, vertical risers) while Ethernet handles your desktops, IP phones, and access points. In addition, fiber cables can transmit data over several kilometers without signal degradation, making them ideal for connecting switches in large campus networks and between different buildings. As they do not emit electromagnetic signals, they're difficult to tap and secure against eavesdropping. They're the two types of cabling you'll find supporting the vast majority of networks ranging from small home LANs up to large ISP data center networks.

How to find the IP address of an industrial Ethernet switch
This blog explores two powerful approaches to solve this problem: Windows API programming (for programmatic or scripted IP retrieval) and lower-layer protocol analysis (using ARP, DHCP, or LLDP to intercept device communications). Finding the IP address of your network switch is crucial for a variety of tasks, from configuring its settings to troubleshooting network connectivity issues. While it might seem like a technical hurdle, several straightforward methods can help you uncover this essential piece of information. SHOCK HAZARD: Labels may be on or inside the equipment, for example, a drive or motor, to alert people that dangerous voltage may be present. You can run the display arp command to view IP addresses and interfaces of servers directly connected to a switch.

Monitoring Core Ethernet Switch
From experience, two monitoring techniques stand out for getting the job done: SNMP (Simple Network Management Protocol) and Network Performance Monitoring (NPM) solutions. In most cases, Ethernet switches are automatically discovered by ONTAP and monitored by CSHM. Here is our list of the best switch monitoring software packages: Paessler PRTG EDITOR'S CHOICE A collection of monitors that includes switch monitoring with SNMP, NetFlow, and other traffic sampling standards. SNMP monitoring provides good insights into a device's CPU and RAM utilization and an individual port's bandwidth and usage.

The core switch is reporting IP conflicts
Confirm the conflict, determine whether DHCP or static assignments are responsible, fix the source, and enforce safeguards through IP planning and IPAM. The difficult part is to understand why the distribution switch has built that ARP entry and the DHCP server sees it as a DHCP client to which it provided the conflicting IP address Start by.
