In the world of telecommunications and data centers, (100 Gigabit Ethernet) is a high-speed networking standard that allows for the transfer of data at 100 gigabits per second. The prefix "Speed" combined with "100100" often refers to optimized performance or double-layered 100GE configurations.
Unlike simply running a single lane at 100 Gbps (which is now possible with newer PAM4 signaling), early 100GE used : speed100100ge
or similar strings are used to manually lock a QSFP28 port to 100Gbps speed. Cisco Nexus 9000 Series: Configuration guides often detail using the command to manage 100GbE ports. Arista EOS: In the world of telecommunications and data centers,
