Configuring the NM-AIC-64, Contact Closure Network Module Chapter 3 Configuring with the Command-Line Interface • SNMP The Cisco IOS software assigns an IP address to the AIC for use by the serial data channel. To route traffic, the serial data channel uses IP over synchronous High-Level Data Link Control (HDLC). All IP packets coming to the Cisco router with a destination IP address that matches the AIC's IP address are forwarded to the serial data channel using IP over HDLC. Asynchronous Craft Port The asynchronous craft port supports Telnet to the AIC's port number. This Telnet method, called local-CLI, is useful for debugging when remote Telnet to the AIC's IP address (remote-CLI) is not applicable. For more information, see the "Configuring the NOC IP Address" section on page 3-40. The asynchronous craft port also supports an AIC boot sequence, similar to the ROM monitor in Cisco IOS software, which allows the user to recover from a corrupted software image or configuration. See the "Override" section on page 3-46. Configuring the AIC From a top-level view, AIC configuration involves assigning an IP address to the AIC using Cisco IOS commands and setting up alarm configurations with either TL1 or the AIC command-line interface (CLI). The flexible TL1 and AIC CLI permit a broad range of alarm configuration scenarios. The following are examplesof alarm configurations that can be programmed with the AIC CLI: Configuring a Discrete Alarm enable config terminal alarm 1 description "west door" normally closed description normal "door closed" description alarm "door open" level 2 exit Configuring an Analog Alarm as an Analog Monitoring Voltage enable config terminal alarm 57 description "tank level" description normal "full" description low "low" description low-low "empty" analog voltage 2.5 30 60 60 exit Configuring an Analog Alarm as a Discrete Monitoring Current enable config terminal alarm 58 description "east door" discrete current-loop 0.0 3.2 5.9 3-36 Software Configuration Guide for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers OL-1957-04
