• tag-int: single octet followed by three octets of integer
value (used for tunneling attribute)
• tag-string: single octet followed by 0-252 octets (used
for tunneling attribute)
pruning
May be replaced with an optional expression that controls
three server features
• whether the attribute is ever sent to the NAS
• whether or not the attribute may be logged
• encapsulation, if used, for vendor-specific attributes
Pruning Expressions
Pruning is a feature that allows the server to remove A-V pairs from an Access-Accept,
Access-Reject, or Access-Challenge message before sending the message to a client that
has been configured for pruning in the clients file, see “The clients File” (page 526).
The pruning to apply is defined by pruning expressions in the dictionary's attribute
entries.
These optional expressions are defined in an attribute entry as follows:
(ack, nak, chall, {NOLOG | ENCAPS | NOENCAPS | CONFIG | INTERNAL})
NOTE: If any value is omitted, but the comma is present for that value, that value
will use its default. If the expression is omitted, all values use their defaults.
ack, nak, chall,
determine how many instances of the attribute may be added
to an Access-Accept (ack), an Access-Reject (nak), or an
Access-Challenge (chall) reply. They can be specified as one
of the following values:
• 0: no attributes of this kind are part of the final reply. This is the default value.
• 1: at most, one attribute of this kind can be part of the final reply.
• *: any number of attributes of this kind can be part of the final reply.
NOTE: Since the default values for ack, nak, and chall are 0, added vendor-specific
attributes will not be returned to the NAS in any replies if you do not include a pruning
expression.
{NOLOG | ENCAPS | NOENCAPS}
define how the server reacts to the attribute:
• NOLOG: the attribute will not be added to the logfile or session logs.
• ENCAPS (or ENCAPSULATE): the attribute will be encapsulated in the vendor-specific
attribute, regardless of the vendor. This is a default value.
• NOENCAPS: the attribute will not be encapsulated within the vendor-specific
attribute.
