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
