Access Lists
Protocol translation software supports access lists, which make it pos-
sible to limit access to the access server from X.25 hosts. Access lists
take advantage of the message field defined by Recommendation
X.29, which describes procedures for exchanging data between two
PADs or between a PAD and a DTE device.
To define X.29 access lists, perform these tasks:
z
Create an Access List
z
Apply an Access List to a Line
When configuring protocol translation, you can specify an access list
number with each
translate
command. When translation sessions
result from incoming PAD connections, the corresponding X.29 ac
cess list is used.
