Example of configuration Manual Feature What gives PAP, CHAP, MS-CHAP and ACL Protection of a network against the non-authorized access Identification of a way and routes Only the updating of the routing table from the known routers who guarantee that no undesirable information from unknown services will be received is accepted. NAT/PAT Hide the internal IP-addresses from the external networks. Prevents any attacks from the external networks on internal units. Expanded protection Inspection system of the network protection with a set of features Cisco IOS Firewall Gives the internal users the safe, dynamic management of access to the Appendixes for all traffic inside a protection zone Provides protection from DOS attacks(denial - of - service - refusal in service Checks the headings of a package rejecting suspicious packages Protects against unidentified dangerous Java applets Provides preventions in real time IP Sec Coding Guarantees integrity of confidential data and authenticity of the original, using the coding on the basis of standards Provides the coding for all users in the local network without configuration of the individual PC with the client programs Integrated qualitative transfer of voice/data 4 analog telephone interfaces (FXS) Provides a qualitative voice transfer on IP (VOIP), and modernizes up to a voice transfer on ATM/AAL2. ПTransfer of signals under the standard H.323 (H.225) Allows the third parties to develop the finished Appendixes enables the fast and cheap decision of VOIP expansion Codecs of compression of voice and DSP G.711, G.729, G.723.1 Provides hardware compression of voice for transfer of a lot of voice streams on separate copper pair, without delays Differentiated classes of service Quality of service (Quality of Service - QoS) Guarantee the Low waiting time of an answer (Low Latency Queing - LLQ) Гарантирует приемлемые задержки для работы различных приложений, оптимально распределяя полосу пропускания Учитывает классификацию приложений и дает наиболее правильный приоритет для использования внешнего канала Choice of Package formation PPP on Ethernet, PPP on ATM and RFC 1483 Compatibility with an existing network is guaranteed Simplification of use Features of interactive debugging Cisco IOS Allows the service providers in a distance or locally to diagnose network problems (for example, through telnet or terminal connection to a router) Cisco IOS CLI Allows clients to increase existing knowledge Cisco IOS CLI, for simpler Installation and management without additional training. Installation, adjustment and management is simplified Cisco Fast Step Software The adjustment becomes simpler by three steps with the help of graphic Interface of the user NAT/PAT Allows the provider of service to reserve address space Reduces time and expenses, simplifying the management of IP Addresses Cisco IOS Easy IP Enables mobile clients to receive IP addresses through a DHCP - server (Dynamic Host Control Protocol) Cisco IOS every time as the client is connected Marked with various colors ports and cables, and the user's guide Helps the user to make appropriate connections Provides clear install commands Doesn't demand the obligatory help of the service provider Removed and Local management Distanced management and the control through SNMP, Telnet or HTTP And local adjustment through the console port
