The core switch has no Ethernet ports
This is because the switch does not know that the connected device is a PC; the switch only knows that the port has changed the state.

Configure multiple ports on the core switch
Sometimes you may need to configure a bunch of ports with the same configuration. If you have the same configuration that needs to be placed on multiple ports, then doing each one individually can be time consuming. Setting up port channels on Cisco switches is an essential skill for network engineers to optimize the performance and reliability of a network.

Can the fiber optic ports on a dual SFP switch connect to different carriers
SFP switches incorporate Ethernet switches through SFP ports that expand connectivity possibilities. Optical transceivers are compact, hot-pluggable devices that convert electrical signals into optical signals, enabling high-speed data transmission across switches, routers, and other networking equipment. You can choose whichever option based on your needs - either using the SFP copper coax SFPs or any of the fibre optics SFPs. Understanding the details of SFP ports and module compatibility will provide you with the knowledge you need to avoid network downtime, streamline performance, and enable the connectivity needed to power the business. An SFP port on a Gigabit switch is a modular interface that accepts Small Form-Factor Pluggable (SFP) transceiver modules.

PoE switch ports are full
Check PoE Budget: Ensure the PoE switch or injector has enough power budget to support all connected devices. This document aims to help provide a basic understanding of how PoE is provisioned on MS switches and some troubleshooting steps to help identify issues with PoE failure on a switch or switch ports. In a basic PoE power supply system, the major components are the power sourcing equipment (PSE), the powered device (PD), and the PoE cables. 3at (PoE+): Up to 30W per port; supported by Cisco Catalyst 9000 "P" models (e.

Which of the two ports on the optical switch should be used
The optical ports on the switch are usually paired together, with one TX sender and one RX receiver. Optical switches are used to reconfigure wavelength cross-connects, enabling support for new light paths. A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP) network that uses a combination of active transmission equipments and passive cable components to provide network connectivity to end user's devices.
