One end is an lc interface and the other end is an sc interface
Most SFP fiber optic modules use LC connectors, while SC connectors are mainly found in legacy networks and MPO/MTP connectors are used for high-density cabling rather than directly on standard SFP modules. If you are upgrading a network switch or deploying fiber to the home (FTTH), you will inevitably face the connector choice: LC vs SC. The LC connector is known for its small size compared to the earlier SC connector.

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).

Commonly Used Port Models of Core Switches
RJ45 ports serve access-layer copper connections; SFP/SFP+ ports enable flexible 1G/10G uplinks; SFP28 delivers 25G for modern data centers; QSFP+ and QSFP28 support high-density 40G/100G spine–leaf fabrics. Ethernet switch port types define the performance, scalability, and architecture of modern networks. What Does Combo Port Mean for Ethernet Switch? Multi-Gigabit Switch for Growing Enterprise Campus Network Confused about SFP, QSFP, or combo ports? This guide explains Ethernet switch port types including RJ45, SFP/SFP+, SFP28, QSFP+/QSFP28, combo, stack, PoE, access, trunk, and hybrid. Ethernet switches are integral components of networking infrastructure, facilitating the efficient transfer of data across devices. This port on 100/1000BASE switch can be used in LANs, data centers for server switching, and uplinks from desktop switches for broadband application.

How to check the port utilization rate of a core switch
From a high-level overview, use the command "sh interface counters". Either the switch is a 3750 L3 switch or 2960-X L2 switch Thanks Jeff 03-07-2017 12:12 AM output of command starts with legend: And of course, statistics are from point of view of interface. You can get insights into network topology and traffic flows by monitoring the ports on network switches. Switch port monitoring is essential for maintaining reliable, efficient, and secure networks. Whether managing a small office or a large enterprise, visibility into port performance helps. You can check the port speed on a Cisco network switch from its command-line interface (CLI) by logging into the switch and then issuing the show interface command.
