Switch Access Port Details

An access port connects an end device like a PC or printer to one VLAN on a Cisco switch. Then you assign a VLAN ID with "switchport access vlan" plus the number. Cisco NX-OS supports only IEEE 802. 1Q-type VLAN trunk encapsulation. This chapter describes the configuration. Ethernet switch ports are fundamental components in modern networking, each serving specific roles depending on network design and performance requirements. 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. The SFP port is commonly found on Gigabit Ethernet switches and is primarily used for fiber optic device connections or for uplinking 1G switches to aggregation/core layer devices, providing higher-bandwidth links. Frames are handled differently according to the type of link they are traversing.
