Hi All,
I want to setup a machine to connect to internet at a limited rate of 64
kbps.
That machine is connected to a switch. so my LAN and Internet both comes
from the same eth0.
How can I limit only the internet access from this machine to 64kbps and
still using 100mbps for LAN
I am trying to implement this Please guide me If i am wrong.
I mark all the packets going out to LAN.
Then I can setup a root qdisc to classify packets based on that mark. If
match then I can setup a class to accept those setup a fifo for those
packets. but if the packets are not for the LAN then i can pass them to
other class which is tbf shaping at rate 64kbps.
Am i right on these lines.
This is the setup
+------------+ eth0 +-----------+ internet
| machine |---------------| Switch |-------------
+------------+ +-----------+
trying to get some thing like this
root qdisc (CBQ or something)
/ \
/ \
/ \
/ \
class class
Internal LAN Pcakets Any other unclassified Packets
| |
| |
FIFO TBF (rate 64kbps)
Please Help me out with marking the packets and to classify them.
Just started off with Traffic Shaping. gigles...... : )
It is alos possible to alternatively to mark internet traffic as it
would be less in comparison to LAN and thus processor friendly.

I tried This for the following setup but it doesn''t seems to be working Please suggest. //making a root cbq tc qdisc add dev eth0 root handle 1:0 cbq bandwidth 100Mbit allot 1514 cell 8 avpkt 1000 mpu 64 //making one class under root with limiting 64kbps tc class add dev eth0 parent 1:0 classid 1:1 cbq bandwidth 1Mbit rate 64Kbit allot 1514 cell 8 avpkt 1000 mpu 64 isolated //Making other class which can take all the packets for the LAN and procced with them at spped available. tc class add dev eth0 parent 1:0 classid 1:2 cbq bandwidth 99Mbit rate 100kbit weight 9kbit allot 1514 cell 8 //filtering the packets so that they can be classified for class 1:2 tc filter add dev eth0 parent 1:0 protocol ip u32 match ip dst 192.168.3.0/32 classid 1:2 tc filter add dev eth0 parent 1:0 protocol ip u32 match ip dst 192.168.2.0/32 classid 1:2 Amit Vyas wrote:> > Hi All, > > I want to setup a machine to connect to internet at a limited rate of > 64 kbps. > That machine is connected to a switch. so my LAN and Internet both > comes from the same eth0. > How can I limit only the internet access from this machine to 64kbps > and still using 100mbps for LAN > > I am trying to implement this Please guide me If i am wrong. > I mark all the packets going out to LAN. > Then I can setup a root qdisc to classify packets based on that mark. > If match then I can setup a class to accept those setup a fifo for > those packets. but if the packets are not for the LAN then i can pass > them to other class which is tbf shaping at rate 64kbps. > > Am i right on these lines. > This is the setup > > +------------+ eth0 +-----------+ internet > | machine |---------------| Switch |------------- > +------------+ +-----------+ > > trying to get some thing like this > > root qdisc (CBQ or something) > / \ > / \ > / \ > / \ > class class > Internal LAN Pcakets Any other unclassified Packets > | | > | | > FIFO TBF (rate 64kbps) > > Please Help me out with marking the packets and to classify them. > Just started off with Traffic Shaping. gigles...... : ) > > It is alos possible to alternatively to mark internet traffic as it > would be less in comparison to LAN and thus processor friendly. > > Amit Vyas > > > > > > _______________________________________________ > LARTC mailing list / LARTC@mailman.ds9a.nl > http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/ >_______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
