Virtual etc interfaces??
So after getting a Nagios plugin up and running that checks certain things including network interfaces, I get an error off the one box I built (as opposed to all of the others that were built by a former employee). The error complains of the "NIC logical group" failing.
All the boxes are HP DL380's with four physical NIC interfaces and an iLO port. For some reason the boxes not built by me all have ifcfg-eth configuration files for eth0 - eth5 (which would be six interfaces). While the machine I build only has eth0 - eth3 which corresponds to the four physical interfaces.
SO, I can assume from the error above, and the fact that eth4 and eth5 are not physical interfaces that they are some kind of logical interfaces configured but I'm not sure where to go from here with my investigation. I'm thinking there is some kind of link aggregation or bonding maybe going on, but not sure how to investigate this in Centos/Linux in general.
Any suggestions would be very much appreciated.

nagios::plugin::config
Nagios::Plugin::Config(3pm) User Contributed Perl Documentation Nagios::Plugin::Config(3pm)
NAME
Nagios::Plugin::Config - read nagios plugin .ini style config files
SYNOPSIS
# Read given nagios plugin config file
$Config = Nagios::Plugin::Config->read( '/etc/nagios/plugins.ini' );
# Search for and read default nagios plugin config file
$Config = Nagios::Plugin::Config->read();
# Access sections and properties (returns scalars or arrayrefs)
$rootproperty = $Config->{_}->{rootproperty};
$one = $Config->{section}->{one};
$Foo = $Config->{section}->{Foo};
DESCRIPTION
Nagios::Plugin::Config is a subclass of the excellent Config::Tiny, with the following changes:
o Repeated keys are allowed within sections, returning lists instead of scalars
o Write functionality has been removed i.e. access is read only
o Nagios::Plugin::Config searches for a default nagios plugins file if no explicit filename is given to "read()". The current standard
locations checked are:
/etc/nagios/plugins.ini
/usr/local/nagios/etc/plugins.ini
/usr/local/etc/nagios /etc/opt/nagios/plugins.ini
/etc/nagios-plugins.ini
/usr/local/etc/nagios-plugins.ini
/etc/opt/nagios-plugins.ini
To use a custom location, set a "NAGIOS_CONFIG_PATH" environment variable to the set of directories that should be checked. The first
"plugins.ini" or "nagios-plugins.ini" file found will be used.
