Cisco VPN 3000 Concentrator
Vendor-Specific Attribute (VSA)
Issue
User does not have (but needs) a Primary DNS set in RADIUS profile
Cisco VPN Concentrator does not work with the Ascend Primary DNS attribute number of 135 set in user profile
Resolution
1. Choose to edit or add Profile
2. From left hand table, choose Vendor-Specific and press button "Add Attribute"
3. In pop-up box, choose Value type to be String Value
4. Enter value: 9 1 "ip:dns-servers=192.168.1.20"
5. Click OK button
If there is a need to enter more than one DNS Server IP address, then separate the IP addresses with space character as shown below:
9 1 "ip:dns-servers=192.168.1.20 192.168.2.21"
As an example, when adding the vendor-specific attribute into the ACE/Server user profile, the Primary DNS should look like the following:
3076 1 "ip:CVPN3000-Primary-DNS=192.168.2.23"
and for the secondary DNS:
3076 1 "ip:CVPN3000-Secondary-DNS=192.168.4.22"
Workaround
