These types of firewalls filter each and every data packet coming from the outside environment such as network; internet so that any kind of virus would not be able to enter in the user's system. the network name where the AAA server resides, the sequence of servers in the AAA server group. 20. By default, they allow traffic from more secure interfaces (higher security level) to access less secure interfaces (lower security level). RADIUS hides passwords during transmission and does not encrypt the complete packet. Ask the user to stop immediately and inform the user that this constitutes grounds for dismissal. Explanation: According to the show crypto map command output, all required SAs are in place, but no interface is currently using the crypto map.
