Cisco Bug: CSCsg34998 - Access Accept with Bad Vendor ID VSA causes authentication failure
May 16, 2018
- Cisco Carrier Routing System
Known Affected Releases
Symptom: When using radus aaa authentication and IOS-XR release 3.4 if the Radius Access Accept message is received which includes a Vendor Specific Attribute (VSA) which IOS-XR does not recognize as a valid vendor ID then authentication may fail. Conditions: This problem did not occur in IOS-XR release 3.3 and earlier. In those releases the unrecognized VSAs are simply ignored by the router and authentication succeeds.
