Power sleep applies to both single lasers or LAGs. > - If single laser or single link, what's might a transition time for an > interface to go from power-sleep to fully-functional/bandwidth-capable look > like -- i.e., is it faster than going from shut to no shut on a typical laser? ? These are typical lasers. No sharks are involved. Power-sleep is a software state to describe an interface that is intentionally shut off and can be reactivated when demand arises. This is intentionally called out to separate it from administratively down or failed. > - What might typical power savings (%) look like when we put an interface > into power sleep mode? 100% of laser power. Possibly additional savings due to associated other circuitry (MACsec, gearboxes, PHY, etc.). Power for all of these should be included in the interface or parent power groups as appropriate. > - What does power sleep bandwidth look like (maybe % wise)? 0% bandwidth on single lasers. On a LAG, the sleeping bandwidth is described in section 7.2.3.
