Y = Enable s IP s upport. N = Dis able s IP s upport. If the VLX is on an Ethe rne t LAN
but doe s not us e IP, e ns ure that IP Enable d = N, or that IP Addre s s =
000.000.000.000. This pre ve nts the VLX from s e nding any IP me s s age s .
The Ethe rne t frame type us e d for incoming and outbound IP trans mis s ions . DIX is
more common. The primary diffe re nce be twe e n frame type s is the LLC he ade r.
DIX = The VLX ge ne rate s and route s DIX (Ethe rne t II) frame s . 802.2 = The VLX
ge ne rate s and route s 802.2 (als o known as 802.3/802.2-not RAW Ethe rne t)
frame s .
The fragme nt re as s e mbly time -out, in s e conds . De fault is 120.
The Maximum Trans mis s ion Unit (MTU) in byte s . De fault is 1500 (typical for
Ethe rne t ne tworks ).
S e ts the initial Time to Live (TTL) value for IP packe ts s e nt from this de vice . TTL
e nume rate s the numbe r of hops (the numbe r of forwarding route rs ) the packe t is
allowe d to pas s be twe e n s ource and de s tination. This pre ve nts looping packe ts
from cras hing route rs and s aturating e ntire links or ne tworks . De fault is 64.
S e ts the 4-bit type of s e rvice (TOS ) value in the IP packe t he ade r. S ome
applications may us e TOS to provide pre ce de nce le ve ls and de te rmine optimum
routing me thods for packe ts . De fault is 0.
Value TOS bits Description
0 0000 Default
1 0001 Minimize monetary cost
2 0010 Maximize reliability
4 0100 Maximize throughput
8 1000 Minimize delay
15 1111 Maximize security
The BACne t Ne twork Numbe r that is as s igne d to the "virtual ne twork" cre ate d by
the IP WAN. All BBMDs participating on the IP WAN (in othe r words , all BBMDs in
the broadcas t dis tribution table ) mus t have this Virtual Ne t s e t to the s ame numbe r.
This Ne twork Numbe r mus t als o be unique with re s pe ct to inte rne tworke d BACne t
LANs . It cannot match othe r BACne t Ne twork Numbe rs (Ethe rne t LANs , MS /TP
LANs , ARCNET LANs , e tc.) De fault is 1.
The IP addre s s as s igne d to this de vice in dotte d-de cimal format. nnn is a numbe r
from 0-255. Follow IP addre s s ing conve ntions and rule s for your ne twork. De fault
is 000.000.000.000, which pre ve nts IP ope ration whe n IP Enable d = Y.
