switchport access vlan vlanID
the switchport access vlan 99 command is used to designate a specific VLAN for a switch port, allowing you to control how traffic on that port is treated and segregated from traffic on other ports and VLANs in the network. This is a fundamental configuration step in building and managing VLANs within a network infrastructure.
The switchport port-security protect command is used in Cisco switches to enable port security on a specific switch port. When this command is configured, the port will allow traffic only from MAC addresses that are already learned and stored in the port's memory. If an unauthorized MAC address tries to connect, the switch will drop the traffic from that address, effectively preventing unauthorized access while allowing legitimate traffic through. This security measure helps to mitigate risks associated with MAC flooding and unauthorized devices.

To duplicate all traffic on one port to another port in a switch, a feature called "port mirroring" or "SPAN" (Switched Port Analyzer) is used. This feature allows the network administrator to configure the switch to send a copy of all the packets from a specified port or VLAN to another designated port for monitoring or analysis. It is commonly used for network monitoring, troubleshooting, and performance analysis.
An Uplink Port is a port on a connectivity device, such as a hub or switch, used to connect it to another connectivity device.
