# Overview #
|
||||
# #
|
||||
# This plugin will check any Dell PowerConnect #
|
||||
# switch. As with most of my plugins, it came out of a #
|
||||
# specific need my company had when my boss decided to #
|
||||
# purchase PowerConnect switches for a remote site. #
|
||||
# (we are traditionally a Cisco shop). When searching #
|
||||
# for plugins, I found FMFreak's PowerConnect plugin, #
|
||||
# but it lacked ability to check environmentals. So, #
|
||||
# this script was designed to do precisely that. I #
|
||||
# also added the ability for it to report asset #
|
||||
# information. #
|
||||
# #
|
||||
# Most options for this program are fairly self- #
|
||||
# explanatory. The only thing worth nothing is that, #
|
||||
# in order to check a specific port, the -p parameter #
|
||||
# has to be used in addition to specifying -t port. #
|
||||
# #
|
||||
# The same applies for environmentals. I decided #
|
||||
# to allow them to be checked individually, but may #
|
||||
# add an option later to also check them all at once #
|
||||
# (like my HP server checks). #
|
||||
# #
|
||||
# This plugin is distributed under the GNU GPL license. #
|
||||
# You may re-destribute only according to the terms of #
|
||||
# the GNU GPL v2. #
