The OVS database in general specifies state, not actions. That is, if you set no ingress_policing_rate, then OVS takes that to mean that it should turn off ingres...

Traffic Shaping: Ingress qdisc not working in Dom0 (3.0.4-1)
Hello, i noticed that the ingress qdisc is not working properly anymore in 3.0.4-1 (back in 3.0.2 the ingress qdisc was working for me): Install the ingress qdisc to peth0: # tc add qdisc dev peth0 ingress ... generate some traffic ... # tc -s qdisc show dev peth0 qdisc pfifo_fast 0: bands 3 priomap 1 2 2 2 1 2 0 0 1 1 1 1 1 1...

Ingress qdisc bypassed on SNAT''ed traffic?
...tcp --dport 80 -j SNAT --to-source 10.32.4.2 (I am using SNAT instead of MASQUERADE for performance reasons). I have several addresses on the 192.168.0.0/16 subnet that I am SNAT''ing similarly. Problem is, ''tc -s filter show parent ffff: dev bond0'' is reporting that the ingress qdisc rule''s for each of these RFC1918 addresses are being bypassed: tc qdisc add dev bond0 ingress tc filter add dev bond0 parent ffff: protocol ip prio 10 u32 match ip dst 192.168.19.23/32 flowid 1:1 action police rate 100kbps burst 200kb drop However, the same lartc ingress filter rul...

Combining ingress and egress ( IMQ+HTB)
I am successfully running ingress (IMQ) and egress (HTB) shaping on a bridge. Is there any way to combine and share the bandwidth between ingress and egress? Example: I have set up www service for egress at 128 KB and ingress at 256 KB. The shaping on them works fine separately. However, I want to create a single virtual pipe for...

Libvirt "tc ingress qdisc" automatically removed by ovs vlan tag setting, how?
With outbound QoS setting in Libvirt XML, libvirt will add a tc ingress qdisc for traffic shaping. Then if you set VLAN tag to that tap device, this qdisc will automatically gone by no reason. Could anyone shed some lights where should I look into? I'm really confused and got no clue here. Thanks! Steps to reproduce -- # virsh start instance-name # virsh dumpxml...

How can I discern egress traffic than ingress traffic?
I have two interfaces, eth0 and eth1 but i can''t discern the egress traffic than ingress traffic. I need to apply htb qdisc in both directions, and I read that I need the IMQ patch to do this, because in ingress qdisc i can''t apply htb qdisc...but where is the ingress qdisc? affect the traffic that goes from eth0 to eth1 or is for the traffic that goes from eth1 to eth0?...

Weird quirk with ingress policing
Hi, I notice that if two or more existing connections match an ingress policing filter, the input bandwidth does not get evenly divided up between the n connections. Kinda like litters of baby animals, where the stronger babies get more access to the mothers teats and grow up bigger and faster than their siblings. The only workaround that''s working for...

Ingress Shaping using IMQ
Hi Guys, Here is a question that is probably of concern to many of us. I am under pressure to provide some solution for ingress traffic shaping. What my customer demands is to divide the downstream (ingress) of an ADSL lines to two classes of traffic - important traffic and non important downloads. He has a very reasonable requirement: he wants a guarantee of at least 1000kbps at all times for the important traffic on the d...

tc show error for ingress
Hi, I am trying to do both ingress and egress bandwidth management on a bridge. eth0 is the WAN interface. IPTraf shows that the following script is running successfully and it limits bandwidth both ways to 256 KB However when I want to see the statistics using tc - it only shows me stats for htb class and not for ingress class. Th...

ingress and egress
ingress can be used to control the incoming packet, such as: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 172.16.1.11 police rate 10kbit burst 10k drop flowid :1 tc filter add dev eth0 parent ffff: protocol ip prio 5 u32 match ip src 1...

Re: Libvirt "tc ingress qdisc" automatically removed by ovs vlan tag setting, how?
After some digging in openvswitch code. My wild guess is that vlan tag reconfiguring triggered iface_configure_qos (vswitchd/bridge.c), which in turn called netdev_set_policing to reset ingress policing rate. Although there's no ingress_policing_rate set in my case, existing ingress qdisc still remove by default. Could some openvswitch guy help to confirm and suggest how to fix or workaround? It seems to be a bug of incompatible with existing ingress qdisc settings. Thanks, -- Qiu Y...

Why this stupid ingress tc does not work ?
Hi ! I wanted to shape my analog modem connection so I took these two lines from the ''wondershaper'' script: tc qdisc add dev $DEV handle ffff: ingress #tc filter add dev $DEV parent ffff: protocol ip prio 50 u32 match ip \ src 0.0.0.0/0 police rate ${DOWNLINK} burst 10k drop flowid :1 with DEV=ppp0 and DOWNLINK=24kbit. But, when I activate it, nothing comes back from the web, no ping. ''tc -s qdisc'' gives: qdisc ingress fff...

Ingress with WonderShaper
...S_ROUTE=y CONFIG_NET_CLS_FW=m CONFIG_NET_CLS_U32=m # CONFIG_NET_CLS_RSVP is not set # CONFIG_NET_CLS_RSVP6 is not set CONFIG_NET_CLS_POLICE=y The whole wshaper.htb script executes fine until the final two commands, and running the first one manually gives me: $ tc qdisc add dev eth0 handle ffff: ingress RTNETLINK answers: Invalid argument Now, the standard solution I''ve seen is "get a newer tc", and one report [1] said that Debian''s unstable one worked fine... so I backported it to woody, but had exactly the same problem :/ I even saw the q_ingress.c and q_htb.c fil...

forwarding in tcng
Hi! I am learning tcng without having experiance of tc and I am trying to build something that shall schedule traffic dependent on the value in the IPv4 packets ip_ttl field. I have read the tcng reference manual and cannot find information about forwarding. Is it possible to farward packets from ingress to egress without sending them upwards in layers? NIC---->ingress---->forward----->egress----> In ingress I do some metering and in egress: classifying and Queuing. Example (basic part of the source): #includes #defines dev eth1 { $P = bucket(rate 1Mbps, burst 2kB, mpu 64B); ingr...

tncg and bandwidth limiting
I''m trying to do some very simple rate-shaping on an interface. I want to limit my 100baseT interface to 7 megs both ingress and egress of the interface. I''ve been hacking my way through the documentation and some examples and I''ve come up with the following configuration for tcng that seems to do what I want. I''m curious if some of the other experts out there wouldn''t have a &quot...
