Ethernet AppleTalk (ELAP) differs from Token Ring AppleTalk (TLAP) 
in AARP packets and in the use of zone multicast addresses. If so 
configured, the ATX will translate AARP packets and will exchange zone 
multicast addresses as needed.
The AppleTalk translation options specify when bridging AppleTalk 
ELAP, TLAP, and AARP packets, whether the packets are to be translated 
to Ethernet-like format. The possibilities for option are:
Off - perform no translation
On - translate the packets
To enable AppleTalk translation from LCM, enter 
translate
 followed by 
a Token Ring port range, 
apple
 and 
on
. For example:
ATX> translate 4-6 apple on
NOTE
On Token Ring, certain AppleTalk packets are transmitted as 
source routing explorers. If translation is enabled, the ATX will 
pass both the original frame and a stripped copy of the frame. 
This may double the multicast traffic on the Internet. Given 
AppleTalk’s propensity for frequent multicast packets, network 
administrators should use this option with care.
