Ethernet Parameters

The AT-4016 as well as the AT-TS95TR, offer the choice of store-and-forward

(the default) or cut-through switching strategies. In store-and-forward, the

AT-4016 stores the entire packet before it is forwarded.

Error packets which do not have a valid Ethernet length will be discarded

using store-and-forward but not with cut-through. Due to this software

implementation, there is a minimal latency difference between cut-through

and store-and-forward. The preferred method is store-and-forward.

Choose the System Administration submenu again and enter the letter E

for Ethernet parameters to access the following submenu:

NOTE

All changes to Ethernet parameters require a system reset to be activated.

The Ethernet parameters screen shows the current choices for

forwarding and for LED modes of operation. At the bottom you see a list of

menu options. Each currently conﬁgured choice is highlighted with an

arrowhead (“>”).

Enter the letter

S or the letters CU if you wish to change the forwarding

mode. Enter the letter T or the letters CO if you wish to change the LED

mode.
