[vpp-dev] issue: ConnectX-5 interface state can not up

Hi community, I have a issue about ConnectX-5 interface test in vpp 22.02: the interface state can not be set to up. driver: mlx5_core version: 5.5-1.0.3 firmware-version: 16.32.1010 (MT_80) expansion-rom-version: bus-info: :b1:00.0 supports-statistics: yes supports-test: yes

Re: [vpp-dev] Outdated home gateway script for NAT?

The “service restart isc-dhcp-server” command is a hack which only knows how to restart the isc-dhcp-server, not dnsmasq. You’ll need to tinker with it to restart dnsmasq, which almost certainly needs to deal with the lstack interface. HTH... Dave From: vpp-dev@lists.fd.io On

Re: [vpp-dev] Outdated home gateway script for NAT?

Hi Dave, Works! I modified the .gate file to define TRUNKHW (the actual hardware interface) and VLAN and updated TRUNK to be the subinterface. Then I added a few lines to create the subinterface, and the rest of the script now automatically referred to the subinterface. So at least the tap

Re: [vpp-dev] Outdated home gateway script for NAT?

I think that you just need to create an L3 vlan subinterface: vpp# create sub-interface 300 At that point, .300 should be an L3 subinterface which will strip vlan tag 300 for RX packets, and add vlan tag 300 for TX packets. Strikes me that that’s exactly what you need. if

Re: [vpp-dev] Outdated home gateway script for NAT?

Hi Dave, Thanks a lot of the update, I have managed to get it to work now, at least as a secondary router behind my ISP router. My ISP wants the WAN port to use VLAN 300, and I can't figure out how to do that. I've tried to push the vlan tag on the outward port set int l2 tag-rewrite $(TRUNK)

[vpp-dev] Outdated home gateway script for NAT?

Hello, I'm quite new to VPP and trying to follow the "VPP as a Home Gateway" setup. After following the installation instructions and copying the configuration files, NAT does not seem to be working. When I enabled NAT44 it gave an outright error: nat44: unknown input `enable users 50

Thank you. I have checked but not much clear on event register and processing. I found the event used in plugins dhcp & vrrp too but all the places have different kinds of implementation. Will you help me to understand by some example to understand the framework or any document/link for reference

Interface is still down which I need for my use-case because that is where the BGP communication is taking place. I tried your git repo and built the container image, now both are working fine. This means the official release has an issue like you said. Thanks for your help! On Thu, Dec 22,

Can you share the git commit id that you used for your 22.10 because I have tried *configuration in startup.conf "linux-cp { default netns dataplane }"* but it is still not working. I have also tried *22.06* and *23.02-rc0~127*, it's the same issue. Also which version of vpp was the

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

Hi Matt I can confirm for VPP 22.10 - command "vppctl lcp default netns dataplane" enable synchronizing interfaces, synchronizing routes fail - configuration in startup.conf "linux-cp { default netns dataplane }" works fine for interfaces and routing Petr čt 22. 12. 2022 v 16:08 odesílatel

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

I'm so sorry ... this is a new issue. I don't know why the lcp tap interface goes down. Can you start it manually? 1. remove command: lcp default netns 'dataplane' (do not use it when VPP already runs in a specific namespace) lcp lcp-sync on lcp lcp-auto-subint on 2. add ip address inside VPP

Now when I start both bird and vpp in the dataplane netns, the dpdk interface goes into down state in the dataplane nents: *root@nat-gw-55896dc777-cxld2:/vpp# ip netns exec dataplane ip a1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000link/loopback

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

Hi, - there is no " ignore lcp default netns" declaration in startup.conf or init.conf. If you start VPP(systemctl vpp start) with no netns configured, plugin linux_nl_plugin.so will not sync correct routing table and fail. - If you run the entire VPP process inside netns dataplane, you can skip

Re: [vpp-dev] Linux-cp Plugin Bird Routes Not Showing Up in VPP

Hi, there can be a few misconfigurations: 1. "lcp default netns dataplane" start synchronizing interfaces/address/etc inside netns "dataplane" (netns "dataplane" must exist) - NOT synchronizing routes 2. plugin "linux_nl_plugin.so" ignore "lcp default netns" configuration => "linux_nl_plugin.so"
