Conﬁguring AppleTalk on an Access Server

Introduction

You can conﬁgure an access server to act as an AppleTalk node on the network

and many different components can then be monitored. The conﬁguration of the

AppleTalk characteristics can be done only in the NVRAM database. This means

that the manager has to reinitialize the access server after making a change to any

of the AppleTalk characteristics before the changes take effect. This chapter does

not address managing asynchronous connections. For information about ATCP,

see Chapter 19. This chapter assumes you have a basic understanding of the

AppleTalk protocol suite.

AppleTalk Address Format

AppleTalk node addresses consist of two ﬁelds: a network number and a node

number. A network number can be in the range 1 to 65534. A node number can be

in the range 1 to 254. The network and node numbers are separated by a period

(.).

Enabling AppleTalk

By default, AppleTalk is not enabled on an access server. In order for the access

server to act as an AppleTalk node on the network, a privileged user has to enable

AppleTalk explicitly with the following DEFINE command:

Local> DEFINE APPLETALK ENABLED

Then the access server has to be reinitialized. Upon reinitialization, the access

server functions as an AppleTalk node by doing the following:

• Acquiring an AppleTalk address and zone

• Registering its AppleTalk name

• Acquiring and defending AppleTalk addresses for attached hosts

• Forwarding AppleTalk DDP packets

• Permitting hosts attached via asynchronous lines to participate in the

AppleTalk protocol

• Responding to SNMP requests for AppleTalk information

• Responding to AppleTalk Echo packets
