
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.
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
Multiple Terminal Functions

Enabling both the synchronous and asynchronous ports to connect the terminals.

Supporting the autocommand function (automatically run commands) and the user-based autocommand 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 autocommand 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.

Implementing the router-based multi-screen terminal function, which allows the terminal to easily switch over
between different servers or different screens of one server.

Supporting the reverse Telnet function, which enables easy management of various serial port devices over a router.
Easy Upgrade

Supporting the asynchronous file transfer X-MODEM protocol, which allows the download of new versions over the
Console port or synchronous port in various operation environments (Windows XP, Windows NT, UNIX, and DOS).

Supporting the download of the new software versions over TFTP.

Supporting BOOTROM online upgrade.

Supporting the USB device and SD card for one-key system upgrade.
