Network Classes Definition File

In Parallels Server Bare Metal, both traffic accounting and bandwidth management are based on network classes. The network classes’ definition file ( /etc/vz/conf/networks_classes ) describes network classes that Parallels Server Bare Metal recognizes. Currently, there can be up to 15 classes defined.

The lines in this file have the following format:

< class_id > < ip_address >/< prefix_length >

where <class_id> defines the network class identifier, < ip_address > defines the starting IP address, and < prefix_length > defines the subnet mask. In pair < ip_address > and < prefix_length > define the range of IP addresses for this class. There may be several lines for each class. Classes should be defined after Class 1 and represent exceptions from the “matching-everything” rule of Class 1. Class 0 has a special meaning and defines the IP ranges for which no accounting is done (this server Container addresses).

The definition of class 1 is required; any class except class 1 can be omitted. However, it is recommended to define class 0 correctly - it will improve performance. For example:

# HW node VPS's networks

0 10.10.10.0/24

0 10.10.15.0/24

# all IP("local" traffic)

1 0.0.0.0/0

# class 2 - "foreign" traffic

#2 10.0.0.0/8

#2 11.0.0.0/8

# inside "foreign" network there

# is a hole with "local" traffic

#1 10.10.16.0/24
