SHOREWALL-TCDEVICES(5)SHOREWALL-TCDEVICES(5)NAME
tcdevices - Shorewall Traffic Shaping Devices file
SYNOPSIS
/etc/shorewall/tcdevices
DESCRIPTION
Entries in this file define the bandwidth for interfaces on which you
want traffic shaping to be enabled.
If you do not plan to use traffic shaping for a device, don´t put it in
here as it limits the throughput of that device to the limits you set
here.
A note on the bandwidth definitions used in this file:
· don´t use a space between the integer value and the unit: 30kbit is
valid while 30 kbit is not.
· you can use one of the following units:
kpbs
Kilobytes per second.
mbps
Megabytes per second.
kbit
Kilobits per second.
mbit
Megabits per second.
bps or number
Bytes per second.
· Only whole integers are allowed.
The columns in the file are as follows.
INTERFACE - [number:]interface
Name of interface. Each interface may be listed only once in this
file. You may NOT specify the name of an alias (e.g., eth0:0) here;
see http://www.shorewall.net/FAQ.htm#faq18
You may NOT specify wildcards here, e.g. if you have multiple ppp
interfaces, you need to put them all in here!
If the device doesn´t exist, a warning message will be issued
during "shorewall [re]start" and "shorewall refresh" and traffic
shaping configuration will be skipped for that device.
Shorewall assigns a sequential interface number to each interface
(the first entry in the file is interface 1, the second is
interface 2 and so on) Beginning with Shorewall-perl 4.1.6, you can
explicitly specify the interface number by prefixing the interface
name with the number and a colon (":"). Example: 1:eth0.
IN-BANDWIDTH - bandwidth
The incoming bandwidth of that interface. Please note that you are
not able to do traffic shaping on incoming traffic, as the traffic
is already received before you could do so. But this allows you to
define the maximum traffic allowed for this interface in total, if
the rate is exceeded, the packets are dropped. You want this mainly
if you have a DSL or Cable connection to avoid queuing at your
providers side.
If you don´t want any traffic to be dropped, set this to a value to
zero in which case Shorewall will not create an ingress qdisc.Must
be set to zero if the REDIRECTED INTERFACES column is non-empty.
OUT-BANDWIDTH - bandwidth
The outgoing bandwidth of that interface. This is the maximum speed
your connection can handle. It is also the speed you can refer as
"full" if you define the tc classes in shorewall-tcclasses[1](5).
Outgoing traffic above this rate will be dropped.
OPTIONS - {-|classify}
classify — When specified, Shorewall will not generate tc or
Netfilter rules to classify traffic based on packet marks. You must
do all classification using CLASSIFY rules in
shorewall-tcrules[2](5).
REDIRECTED INTERFACES - [interface[,interface]...]
Added in Shorewall-perl 4.1.6. May only be specified if the
interface in the INTERFACE column is an Intermediate Frame Block
(IFB) device. Causes packets that enter each listed interface to be
passed through the egress filters defined for this device, thus
providing a form of incoming traffic shaping. When this column is
non-empty, the classify option is assumed.
EXAMPLES
Example 1:
Suppose you are using PPP over Ethernet (DSL) and ppp0 is the
interface for this. The device has an outgoing bandwidth of 500kbit
and an incoming bandwidth of 6000kbit
#INTERFACE IN-BANDWIDTH OUT-BANDWIDTH OPTIONS REDIRECTED
# INTERFACES
1:ppp0 6000kbit 500kbit
