Hi all, I''m having a hell of a time getting my IFB to work. I know I''ve done this before, so I''m missing something stupid. Can anybody tell me what it might be? Configs as follows: -------- #!/bin/sh modprobe ifb numifbs=1000 modprobe act_mirred modprobe 8021q brctl addbr br0 brctl setfd br0 0 brctl stp br0 off brctl addif br0 eth1 brctl addif br0 eth2 ifconfig eth1

Hi All, I''m trying to do some traffic shaping with IFB. I have installed Ubuntu 6.0.6 and upgraded to the 2.6.17.7 kernel. I have an ifb0 device. However, I think I may have the wrong version of TC installed, because it doesn''t like the ''mirred'' argument. What version of iproute should I be using, and how can I upgrade it? apt-get update iproute

Hi all, I''m having a hell of a time getting tc and IFBs to co-operate. I''ve copied the following from http://linux-net.osdl.org/index.php/IFB: -- export TC="/sbin/tc" $TC qdisc add dev ifb0 root handle 1: prio $TC qdisc add dev ifb0 parent 1:1 handle 10: sfq $TC qdisc add dev ifb0 parent 1:2 handle 20: tbf rate 20kbit buffer 1600 limit 3000 $TC qdisc add dev ifb0

Hi all, I''m having some problems setting up qdiscs on a bridge.The config looks a little like this: ifconfig ifb0 up # Bring up the IFB for this bridge. tc qdisc add dev eth2 ingress tc qdisc add dev eth3 ingress tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000 cell 8 # Raw qdiscs on each bridge port tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

Hi All, I''m trying to do some traffic shaping on an ethernet bridge. Currently, I have the following setup working: ifconfig eth0 down brctl addbr br0 brctl addif br0 eth0 brctl addif br0 eth1 brctl stp br0 off ifconfig eth0 0.0.0.0 up ifconfig eth1 0.0.0.0 up ifconfig br0 up This creates a bridge consisting of eth0 and eth1. So far so good. I now want to use tc to shape traffic

Hi all, I''m sure I''m soing something wrong here. I am trying to set up a rate limit inside another rate limit. eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so that packets passing through the bridge are counted at each port.(ie the throughput is limited to 512K, not just the traffic in one direction.) This part works OK, but I also want to limit a

Hi all, Can anybody tell me what the maximum number of handles are that I can use when setting up qdiscs and classes in tc?

Hi All, I need to do some tricky filtering stuff. Can anyone tell me if any of the following are possible? * match on a combination of firewall mark AND u32 criteria. ie. handle 6 fw AND u32 match ip src 1.2.3.4/32 - to match packets from 1.2.3.4 which have been marked elsewhere OR * to OR the values of u32 matches. Something like u32 match ip src 1.2.3.4/32 OR match ip dst 1.2.3.4/32 - to

Hi, I''m looking for info about IFB devices and how I can use it to incomming traffic shapping. Has IFB any web about it? Do any body known where I can find more info about it? I found this: http://linux-net.osdl.org/index.php/IFB But I can''t stand fine how to use it to allow many ifb''s devices or how to use it with "tc actions". Any help? Thanks --

I''ve network with NATed hosts. I want to catch only all traffic going from my server, but I don''t want catch NATed traffic from LAN. I need only traffic going from/to my server (traffic from INPUT, OUTPUT chain in iptables) (like SSH, postfix, WWW or proxy). This is throw all traffic from my LAN to IFB: $TC qdisc add dev $iface_lan handle ffff: ingress $TC qdisc add dev

Hello, I want to use IFB instead of imq, but i don''t know how to redirect traffic from eth2.101 to ifb0 and traffic from eth1.301 to ifb1 so I can applied QoS. With IMQ i use iptables -j IMQ --to-dev 0. Is it possible to apply tc rules on ifb1 both download/upload ? thx _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl

Dear all, I am working on a linux box (2.4.22 kernel) which is used as a bridge. And I want to add traffic control rules on it by client''s MAC. Does anyone has such experience on how to do that? Thank you very much!! Best regards, Henry _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Hi, I am using linux kernle-2.6.15, iptables-1.4 and bridge-utils-1.4. Everything intslled without any issue and i am able to enable the bridge and traffic is also flowing without any issue. But i did not see any traffic on the iptables forward chain due to which i am not able to control the traffic. Do i requie enable anything more to make the traffic pass through iptables forward chain.

Hi All, I''m using HTB to shape traffic, a little like this: tc qdisc add dev eth2 root handle 1:0 htb tc qdisc add dev eth3 root handle 1:0 htb tc filter add dev eth2 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action ipt -j MARK --or-mark 0x01000000 tc filter add dev eth3 parent 1: protocol 0x8100 prio 5 u32 match u16 3000 0x0fff at 0 flowid 1:1 action

Hello Tom, Sorry, please but i again return to IFB question. If i correct understand in current situation IFB haven't profit from ESFQ in common cases (i mean internal networks masquarading) so as we wait from ESFQ allocates bandwidth fairly per source IP(internal) but IFB don't know internal IPs. If i correct, what do you think what can help IFB to solve its main disadvantage

Hello list, I've posted here about this before, but I realise that it may have been assumed that the bridged vlans simply put a switch port in a blocking state and left my question ignored. So to recap. I have two tg3 interfaces named 'in' and 'out' and a bridge named 'br0' My vlan trunk is on the 'in' side of the network, and set as in.2, in.3 ... The

Hi all, Is it possible to invoke an ebtables target from tc? Ie we can use the ''action ipt'' to invoke an IPTables target, but I was wanting to use an ebtables target instead. Is this possible?

Hi All, Is there any way to set the maximum latency on a cbq when it is overloaded? Or, for that matter, to query it? For example, I want to know how long (in seconds) a packet will stay in the queue before it is dropped, and I want to be able to adjust this figure.

Hi all, Is is possible to configure the u32 classifier to match on VLAN ID? Or any other bits in the 802.1 header for that matter? If so, can anybody tell me how? Or where to find out how?

Hi All, Is it possible to mangle the 802.1p priority bit on a packet as it gets bridged? I can''t find anything in either the iptables or ebtables docs to tell me how it''s done.
