# CHANGES
# -------
# v0.3a2- fixed bug in "if" operator. Thanks kad@dgtu.donetsk.ua.
# v0.3a- added TIME parameter. Example:
# TIME=00:00-19:00;64Kbit/6Kbit
# So, between 00:00 and 19:00 RATE will be 64Kbit.
# Just start "cbq.init timecheck" periodically from cron (every 10
# minutes for example).
# !!! Anyway you MUST start "cbq.init start" for CBQ initialize.
# v0.2 - Some cosmetique changes. Now it more compatible with
# old bash version. Thanks to Stanislav V. Voronyi
# <stas@cnti.uanet.kharkov.ua>.
# v0.1 - First public release
#
# README
# ------
#
# First of all - this is just a SIMPLE EXAMPLE of CBQ power.
# Don't ask me "why" and "how" :)
#
# This is an example of using CBQ (Class Based Queueing) and policy-based
# filter for building smart ethernet shapers. All CBQ parameters are
# correct only for ETHERNET (eth0,1,2..) linux interfaces. It works for
# ARCNET too (just set bandwidth parameter to 2Mbit). It was tested
# on 2.1.125-2.1.129 linux kernels (KSI linux, Nostromo version) and
# ip-route utility by A.Kuznetsov (iproute2-ss981101 version).
# You can download ip-route from ftp://ftp.inr.ac.ru/ip-routing or
# get iproute2*.rpm (compiled with glibc) from ftp.ksi-linux.com.
#
#
# HOW IT WORKS
#
# Each shaper must be described by config file in $CBQ_PATH
# (/etc/sysconfig/cbq/) directory - one config file for each CBQ shaper.
#
# Some words about config file name:
# Each shaper has its personal ID - two byte HEX number. Really ID is
# CBQ class.
# So, filename looks like:
#
# cbq-1280.My_first_shaper
# ^^^ ^^^ ^^^^^^^^^^^^^
# | | |______ Shaper name - any word
# | |___________________ ID (0000-FFFF), let ID looks like shaper's rate
# |______________________ Filename must begin from "cbq-"
#
#
# Config file describes shaper parameters and source[destination]
# address[port].
# For example let's prepare /etc/sysconfig/cbq/cbq-1280.My_first_shaper:
#
# ----------8<---------------------
# DEVICE=eth0,10Mbit,1Mbit
# RATE=128Kbit
# WEIGHT=10Kbit
# PRIO=5
# RULE=192.168.1.0/24
# ----------8<---------------------
#
# This is minimal configuration, where:
# DEVICE: eth0 - device where we do control our traffic
# 10Mbit - REAL ethernet card bandwidth
# 1Mbit - "weight" of :1 class (parent for all shapers for eth0),
# as a rule of thumb weight=batdwidth/10.
# 100Mbit adapter's example: DEVICE=eth0,100Mbit,10Mbit
# *** If you want to build more than one shaper per device it's
# enough to describe bandwidth and weight once - cbq.init
# is smart :) You can put only 'DEVICE=eth0' into cbq-*
# config file for eth0.
#
# RATE: Shaper's speed - Kbit,Mbit or bps (bytes per second)
#
# WEIGHT: "weight" of shaper (CBQ class). Like for DEVICE - approx. RATE/10
#
# PRIO: shaper's priority from 1 to 8 where 1 is the highest one.
# I do always use "5" for all my shapers.
#
# RULE: [source addr][:source port],[dest addr][:dest port]
# Some examples:
# RULE=10.1.1.0/24:80 - all traffic for network 10.1.1.0 to port 80
# will be shaped.
# RULE=10.2.2.5 - shaper works only for IP address 10.2.2.5
# RULE=:25,10.2.2.128/25:5000 - all traffic from any address and port 25 to
# address 10.2.2.128 - 10.2.2.255 and port 5000
# will be shaped.
# RULE=10.5.5.5:80, - shaper active only for traffic from port 80 of
# address 10.5.5.5
# Multiple RULE fields per one config file are allowed. For example:
# RULE=10.1.1.2:80
# RULE=10.1.1.2:25
# RULE=10.1.1.2:110
#
# *** ATTENTION!!!
# All shapers do work only for outgoing traffic!
# So, if you want to build bidirectional shaper you must set it up for
# both ethernet card. For example let's build shaper for our linux box like:
#
# --------- 192.168.1.1
# BACKBONE -----eth0-| linux |-eth1------*[our client]
# ---------
#
# Let all traffic from backbone to client will be shaped at 28Kbit and
# traffic from client to backbone - at 128Kbit. We need two config files:
#
# ---8<-----/etc/sysconfig/cbq/cbq-28.client-out----
# DEVICE=eth1,10Mbit,1Mbit
# RATE=28Kbit
# WEIGHT=2Kbit
# PRIO=5
# RULE=192.168.1.1
# ---8<---------------------------------------------
#
# ---8<-----/etc/sysconfig/cbq/cbq-128.client-in----
# DEVICE=eth0,10Mbit,1Mbit
# RATE=128Kbit
# WEIGHT=10Kbit
# PRIO=5
# RULE=192.168.1.1,
# ---8<---------------------------------------------
# ^pay attention to "," - this is source address!
#
# Enjoy.
