DGS-3312SR Stackable Gigabit Layer 3 Switch

The Switch allows the user to configure two types of gigabit connections;

1000M/Full_M and 1000M/Full_S. Gigabit connections are only supported in full

connections running a 1000BASE-T cable for connection between the Switch port

and other device capable of a gigabit connection. The master setting

(1000M/Full_M) will allow the port to advertise capabilities related to duplex, speed

and phy etermine the master and slave

relatio al layers. This relationship is

necessary for establishing the timing control between the two physical layers. The

timing control is set on a master physical layer by a local source. The slave setting

e timing comes form a data stream

other choices listed.

The 1000M/Full_M (master) and 1000M/Full_S (slave) parameters refer to

in a link down status for both ports.
