Ethernet: In these Cisco Switches models all the ports are Gigabit Ports.

PoE Ports: In PoE Ports “ All “ shows that all ports can be used as PoE ports.

SFP Ports: * shows that all ports can be used as SFP ports.

PoE (Power): PoE (power), is the max power consumed by Cisco catalyst 3750-G switch when all ports are being used as PoE. The entry mentioned with “ – “ shows that switch don’t have PoE ports.

Power (Watt): In Power column, the operational power of switch is given. The entry mentioned with “ – “ shows that switch power is already given in PoE (power) column, as this switch has PoE ports.
