# This script is provided with no support or guarantees.
# You may use it, modify and distribute with no restrictions
# as long as original author is mentioned.
#
# Script is designed for embedded operation within Comware OS on HP 5130EI Switch.
# It purpose is to check if servers with static ip is plugged in the right port on the switch.
# If wrong port is detected, it then automatically send syslog message to inform administrator
# Administrator has to declare ip in the corresponding interface description.
# For example,
# interface GigabitEthernet1/0
#   description 192.168.0.13
#
# Usage:
# <Switch1>python staticip.py
#
# You may also run script automatically when link up/down interface
# is recognized by leveraging Comware EAA:
# [Switch1]rtm cli-policy POL1
# [Switch1-rtm-POL1]event syslog priority all msg "link status is up" occurs 1 period 1
# [Switch1-rtm-POL1]action 0 cli python staticip.py
# [Switch1-rtm-POL1]running-time 180
# [Switch1-rtm-POL1]user-role network-admin
