•Off - perform no translation

Translation Options

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.

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.

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
