Cisco AV Pair Attribute Syntax
The Cisco Attribute Value (AV) pair (ID Number 26/9/1) can be used to enforce access lists from a
RADIUS server (like Cisco ACS), or from an LDAP server via an LDAP attribute map.
The syntax of each Cisco-AV-Pair rule is as follows:
[Prefix] [Action] [Protocol] [Source] [Source Wildcard Mask] [Destination] [Destination Wildcard
Mask] [Established] [Log] [Operator] [Port]
Table B-3 describes the syntax rules.
WebVPN-SVC-Rekey-Period Y Y Integer Single 0 = Disabled
n = Retry period in minutes
(4 - 10080)
WebVPN-SVC-Required-Enable Y Y Integer Single 0 = Disabled
1 = Enabled
WebVPN-URL-Entry-Enable Y Y Integer Single 0 = Disabled
1 = Enabled
WebVPN-URL-List Y String Single URL list name
