check_mc.exp

Project Notes

This plugin requires Expect, works on NetBSD and should work on Linux.

Usage:
check_mc-0.1.exp
[-u|--login login]
[-p|--password password]
[-l|--tty terminal_line]
[-s|--speed terminal_speed]
[-E|--online path_list]
[-F|--100Mb path_list]
[-G|--1Gb path_list]
[-d|--debug file]
[-h|--help]

Default values for login, password and terminal_speed match factory defaults on AT S97 management application ('manager', 'friend', 115200). Default value for line is /dev/ttyS0.

-E stands for 'Ethernet' or 'Enabled'
-F stands for 'FastEthernet'
-G stands for 'GigabitEthernet'

A path_list is of the form: chassis_id/module_id/interface_id. chassis_id should always be 0 where no stacking is used; module_id refers to converters blade (1 is left blade, 2 is right blade); interface_id refers to individual converters. These are AT conventions. The script extends path_list according to usual conventions; thus:
0-3/1,2/1-4,6,8-12 refers to interfaces 1 to 4, 6 and 8 to 12 of modules (blades) 1 and 2 on chassis 0 to 3. Most real-life usage would not be that complex, though.

The script checks for minimal requirements on rate. If a particular converter should be running at 100Mb/s, the script will issue an alert if either or both of copper and fiber sides are down or running at 10Mb/s, and will remain silent if either or both side are running at least at 100Mb/s.

Examples:
check_mc.exp -l /dev/ttyUSB0 -F 0/2/1-11
will check that the converters 1-11 of right (2) blade of the device connected on /dev/ttyUSB0 are all running at least at 100Mb/s (FastEthernet)

When an alarm is raised, the report yields information about faulty side (copper, fiber, both...).

The debug mode enables expect debugging; special value '-' allows debug messages to be displayed on stdout.

This script should also provide a good starting point for anyone willing to develop a tiny plugin with expect.
