1-6 CHAPTER 1: LANPLEX® EXTENDED SWITCHING FEATURES

Appletalk Menu From the appletalk menu, you can view information about and conﬁgure Appletalk interfaces, routes, and zones. You can also administer the Appletalk Address Resolution Protocol (AARP), AppleTalk forwarding, and statistics. Figure 1-4 shows the Appletalk menu. For example, to deﬁne a new AppleTalk interface, you would enter appletalk at the top-level menu, interface at the AppleTalk menu, then deﬁne at the interface menu.
