Symptoms: Terminal window PPP clients may fail with Cisco Access servers.

Conditions: This symptom has been observed on Cisco AS5400 gateways and Cisco AS5800 
servers.

Workaround: There is no workaround. 

CSCir00074

Symptoms: A router crashes when the casnDisconnect object is set to “true” for a PPPoE session.

Conditions: This symptom is observed on a Cisco 10000 series when you attempt to terminate the 
PPPoE session through SNMP by using the casnDisconnect object of the 
CISCO-AAA-SESSION-MIB.

Workaround: There is no workaround.

Symptoms: Users may be able to access root view mode (privilege level) 15 without entering a 
password.

Conditions: This symptom is observed on a Cisco router that has the Role-Based CLI Access feature 
enabled and occurs when the none keyword is enabled in the default login method list.

For example, the symptom may occur when you enter the aaa authentication login default group 
tacacs+ none. When the TACACS+ server is down, users are allowed to enter non-privileged mode. 
However, users can also access the root view through the enable view command without having to 
enter a password.

Workaround: Ensure that the none keyword is not part of the default login method list.

Further Problem Description: The fix for this caveat places the authentication of the enable view 
command in the default login method list. 

CSCsb43767

Symptoms: RADIUS stop packets that are sent to a RADIUS server may contain an incorrect value 
for the NAS-Port attribute (RADIUS IETF attribute 5). Information that is related to the 
asynchronous interface is not included in the Cisco-NAS-port VSA.

Conditions: This symptom is observed on when a Cisco router sends stop packets to a RADIUS 
server via an asynchronous interface.

Workaround: There is no workaround.
