Configure MTU size on an Interface
The E-Series supports a link Maximum Transmission Unit (MTU) of 9252 bytes and maximum IP MTU of
9234 bytes. The link MTU is the frame size of a packet, and the IP MTU size is used for IP fragmentation.
If the system determines that the IP packet must be fragmented as it leaves the interface, FTOS divides the
packet into fragments no bigger than the size set in the
In FTOS, MTU is defined as the entire Ethernet packet (Ethernet header + FCS + payload)
Since different networking vendors define MTU differently, check their documentation when planing
MTU sizes across a network.

Ethernet Pause Frames
Threshold Settings
Ethernet Pause Frames allow for a temporary stop in data transmission. A situation may arise where a
sending device may transmit data faster than a destination device can accept it. The destination sends a
PAUSE frame back to the source, stopping the sender's transmission for a period of time.
