Carrier Access SNMP manual Command Line Interface, Local and Remote CLI Management

Agent. Normally, the Manager polls the Agent periodically to check traffic statistics. However, the Manager can also set thresholds for traps. Traps specify network events and conditions for which the Agent automatically sends a Telnet alarm message with trap data back to the Manager.

1.7.3 Command Line Interface

The Access Bank II SNMP comes with a built-in Command Line Interface. CLI provides complete management of all Access Bank features through any VT-100 terminal or PC connected to the RS- 232 port, or through any Telnet terminal connected to the Ethernet 10Base-T port.

CLI works with a communications terminal, in which you type in text and press the carriage return key to send the message to the host. The host then responds with a log-on message, and the CLI is ready to use.

CLI is easy to use because the Access Bank II SNMP provides a list of menu options to choose from. Furthermore, context sensitive help is available to guide you through the setup process. At any time, you can type in a question mark (?) to obtain information about what to type next or what commands are available. You can also type “help” after any command to get specific help with that command.

1.7.3.1 Local and Remote CLI Management

The Access Bank II SNMP provides CLI management through its RS-232 and Ethernet 10Base-T ports, as shown in Figure 1-2and Figure 1-3.

For RS-232 CLI control, just connect a PC or laptop computer to the RS-232 management port on the Access Bank II/SNMP. Then use a VT-100 terminal emulation program such as Microsoft Hyper Ter- minal®. (The default communications port settings are 9600, 8, 1, N.) Press the Escape key to initiate the link. The Access Bank will return a log-on message. If a password is required, the Access Bank will request that you enter a password. (Units shipped from the factory do not have a password defined, but the user is encouraged to use passwords to prevent unauthorized use.) CLI can be used from a remote site by connecting the RS-232 port to a modem and telephone line.
