• 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 page3-40.
The asynchronous craft port also supports an AIC boot sequence, similar to the ROM monitor in
CiscoIOS software, which allows the user to recover from a corrupted software image or configuration.
See the “Override” section on page3-46.
Configuring the AIC
From a top-level view, AIC configuration involves assigning an IP address to the AIC using CiscoIOS
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 AICCLI:
