Re: [vpp-dev] MTU in vpp

Hi, If dpdk plugin used, which is the default case in VPP, MTU to each interface is set by retrieving MTU information from underlying DPDK PMD API: rte_eth_dev_info_get(). So if the device supports max MTU say 9216 then that will be configured. I don't think setting MTU via vpp cli or

Re: [vpp-dev] Raydonetworks's implementation of pppoeclient for vpp

Hi Hongjun, Thanks a lot for your explanation, the implementation only use partial pppd code, if BSD license is ok for vpp project, the previous license concern is resolved. I will build agains master and submit patch to vpp project later when I have spare time. -- Original

Re: [vpp-dev] Raydonetworks's implementation of pppoeclient for vpp

Hi Ray, The implementation is already prototyped as two plugins, regarding upstreaming it to fd.io vpp, there are the following concerns: 1. the license issue, we don't know it's acceptable the plugins contain third party pppd code which use different license, hope maintainer can give some

[vpp-dev] NAT output-feature

Hi, The NAT plugin CLI command to configure an interface to participate in NAT has a flag “output-feature” that affects how outbound (“in2out”) processing is done. Can the output-feature option be used in any situation where the standard in2out processing can be used? Are there any

Re: [vpp-dev] VPP with pipe line processing.

Early in the process of deciding how to make vpp multi-thread capable, I placed node subgraphs onto specific threads and handed off frames between threads. As expected, the resulting pipelines ran at the speed of the slowest stage. When the workload changed, it was necessary to repartition the

[vpp-dev] check check checkstyle

FYI: Checkstyle is its own jenkins job now that will run before the rest of the verify ‘set’. So no more checkstyle at the start of every individual job. Due to necessity with how the jenkins is configured on success you will see a checkstyle success message added as a gerrit comment. On

[vpp-dev] VPP with pipe line processing.

All, I tried to find this on VPP wiki and on web, but no luck hence question here. I wanted to try pipe line processing in VPP (each core doing specific job and passing on the packets further to next core for subsequent processing and finally send out). In other words, use case is multi threaded

Re: [vpp-dev] Raydonetworks's implementation of pppoeclient for vpp

Hi folks, This is good work - would you consider upstreaming as a plugin to FD.io VPP? Looks like you have a lot of this work done already? Ray K On 07/05/2018 05:55, "张东亚 wrote: Hi List, As a SDN startup(www.raydonetworks.com) in China, we have implemented pppoeclient support for vpp

[vpp-dev] MTU in vpp

Hi I set mtu to all of my interfaces using "vppctl set interface mtu 1500 ". But when I generate packets larger than mtu size, all packet pass through vpp. Is there any parameter that I must set? I generate large packet using "ping -M do -s 9472 200.200.200.40". My vpp version: master

Re: [vpp-dev] Fragmented IP and ACL

Dear Andrew I like to write this test as a testcase, I will work on that in my spare time. I like your solution about separate code path, but I think defragmentation could solve the problem and reassembly may have overhead. In defragmentation, information of fragmented packets is kept and all of

Re: [vpp-dev] Fragmented IP and ACL

Yeah back in the day the fragment reassembly code was not there yet, so there is a choice either to drop all the fragments on the floor, or rely on the receiving TCP stack to drop the non-initial fragments, like IOS did. There is a knob that allows you to choose the behavior between the two by
