1.5.4 Multiple Diagnosis and Management Tools
Providing complete debugging and tracing tools as well as complete DEBUG commands for easier accurate
location of various network faults.
Providing rich statistics and information display functions to allow the users to easily know the network
performance and running status.
Supporting SNMP for monitoring and controlling the router by using common network management software.
Supporting login through terminals.
1.
Supporting configuration over the Console port
2.
Supporting login and configuration over Telnet.
3.
Supporting login and configuration over the serial port.
4.
Supporting login and configuration over remote dial-up.
1.5.5 Superior Security
Using perfect firewall and IP packet filtering technology to enforce strict check on network addresses, port
numbers, or protocol types.
Supporting AAA and RADIUS.
Realizing Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) on
Point-to-Point Protocol (PPP), supporting callback, and enhancing security.
Providing level-based password check and security logs.
Implementing dynamic routing-protocol password/key authentication in OSPF and RIP V2.
Supporting NAT.
Providing IPSEC/IKE data encryption
Supporting GRE tunnel encapsulation
Providing VLAN technology
1.5.6 Multiple Terminal Functions
Enabling both the synchronous and asynchronous ports to connect the terminals.
Supporting the auto command function (automatically run commands) and the user-based auto command
function (allow different users to run different commands) on terminal ports.
Supporting the command alias and telnet script, which can be used together with the auto command function to
directly log in to the server after pressing
Enter
on the terminal.
Supporting the fixed terminal dial-up function based on different operating systems, where a terminal uses the
same terminal number for multiple times of login.
Supporting the real terminal. The terminal logs in to the server over the router and act as a real terminal (tty) for
the server, not needing the modification of the old programs, thereby protecting the existing investment.
