 +# Pause Frames
 +
 +Ethernet Pause Frames is a mechanism for [flow control](/​glossary/​f/​flow_control) which is used to cause a temporary stop of transmission from the origin. Typically it is used when the sender *temporarily* or *intermittently* transmits faster than the device can receive.
 +
 +The PAUSE frame is defined by IEEE 802.3x and uses MAC Control frames to carry the PAUSE commands. Ethernet pause frames are supported on full duplex only.
 +
 +**Note:** If a port is over-subscribed,​ Ethernet Pause Frame flow control does not ensure no-loss behavior.
