Energy-Aware States (EAS)
=>motivate a strategy of jointly adopting LCPs+NCPs to optimize energy consunmption in a hierarchical way
1. Entity 1’s LCP selects the chassis containing the the physical port bound to the logical link
2. The chassis’s LCP(entity1.2) forwards the command to the corresponding line card (entity 1.2.2), and reduces the fans’ speed
3. If no other links active, the layer-3 LCP sends the entire line card to sleep
4. Otherwise, the LCP puts the physical interface into standby mode and reduce the performance of all hardware components that process packets for that port
