VPP/XDP feature help

dsouthwi · April 15, 2025, 8:09pm

Hi all,

As VPP & XDP are now included in rolling for some time, I’d like to ask how people are using it. The barebones documentation teases some ~600% increase in throughput, but with little documentation of all the new config options. As 25G home connections are cheaply available in my country, this is very interesting to me, but I’m struggling to get off the ground:

trying to apply on a mlx5 (ConnectX4 - 25Gx2) on VyOS 2025.04.09-0018-rolling:

# show vpp
+nat44 {
+    source {
+        inside-interface eth2
+        outside-interface eth1
+    }
+}
+settings {
+    cpu {
+        corelist-workers 1-3
+        main-core 0
+    }
+    interface eth1 {
+        driver xdp
+    }
+    interface eth2 {
+        driver xdp
+    }
+    memory {
+    }
+}

makes vyos very unhappy:

# commit

I also note I cannot install mlx5 dpdk drivers (OFED), due to vyos repos not containing the required packages (automake, dkms, flex, bison, etc…). Maybe this is the issue?

Has anyone been able to test VPP with any network card vendor?

Viacheslav · April 16, 2025, 5:02am

What do you see after this error if you try this
sudo /usr/bin/vpp -c /run/vpp/vpp.conf

Did you try DPDK driver?

dsouthwi · April 16, 2025, 2:58pm

Ah - it barfs at empty memory key:

$ sudo /usr/bin/vpp -c /run/vpp/vpp.conf
unknown 'memory' config input ''

Unfortunately totally lacking from documentation.
I will set some default and report back this evening (with dpdk test too)

Viacheslav · April 16, 2025, 5:26pm

Delete the empty memory option

dsouthwi · April 22, 2025, 7:53pm

Hmm tried again with DPDK config:

+ vpp {
+     interfaces {
+         vxlan vxlan10 {
+             kernel-interface "vpptap10"
+             remote "10.10.10.2"
+             source-address "10.10.10.1"
+             vni "3"
+         }
+     }
+     kernel-interfaces vpptap10 {
+         address "10.10.10.3/24"
+     }
+     settings {
+             source-address "10.10.10.1"
+             vni "3"
+         }
+     }
+     kernel-interfaces vpptap10 {
+         address "10.10.10.3/24"
+     }
+     settings {
+         cpu {
+             corelist-workers "3"
+             corelist-workers "2"
+             main-core "0"
+         }
+         interface eth1 {
+             dpdk-options {
+                 num-rx-queues "2"
+                 num-tx-queues "2"
+             }
+             driver "dpdk"
+         }
+         interface eth2 {
+             dpdk-options {
+                 num-rx-queues "2"
+                 num-tx-queues "2"
+             }
+             driver "dpdk"
+         }
+         memory {
+             main-heap-page-size "default-hugepage"
+             main-heap-size "4G"
+         }
+         statseg {
+             page-size "default-hugepage"
+             size "256M"
+         }
+     }
+ }

and sudo /usr/bin/vpp -c /run/vpp/vpp.conf reports:

dsouthwi@vyos# sudo /usr/bin/vpp -c /run/vpp/vpp.conf
Main heap allocation failure!

when trying with commit-confirm, I get

dsouthwi@vyos# commit-confirm 5

commit-confirm will automatically reload previous config in 5 minutes
unless changes are confirmed.
Proceed ? [Y/n]

Is this referring to flowtables - eg routing offload? or a driver offload? Message is unclear.

Im unconfidently assuming they’re incompatible with the dataplane and all… but I guess no checks are done as of yet.

I’ve tried to enable tc-flower on my mlx5 device, but apparently that requires mellanox mst/mft drivers, which is difficult (easy in debian)

Viacheslav · April 23, 2025, 5:53am

Something is wrong with memory section
Why not remove it at all during the test?
Try this minimal config

set vpp settings interface eth0 driver 'dpdk'
set vpp settings interface eth1 driver 'dpdk'

set vpp interfaces vxlan vxlan10 remote '192.0.2.2'
set vpp interfaces vxlan vxlan10 source-address '192.0.2.1'
set vpp interfaces vxlan vxlan10 vni '10'

set vpp interfaces loopback lo10 kernel-interface 'vpptun10'

set vpp interfaces bridge br10 member interface eth1
set vpp interfaces bridge br10 member interface vxlan10
set vpp interfaces bridge br10 member interface lo10 bvi

set vpp kernel-interfaces vpptun10 address '100.64.0.1/24'

dsouthwi · April 23, 2025, 8:29pm

Hmm, tried this but no love. From your example:

+ vpp {
+     interfaces {
+         bridge br10 {
+             member {
+                 interface eth2 {
+                 }
+                 interface lo10 {
+                     bvi
+                 }
+                 interface vxlan10 {
+                 }
+             }
+         }
+         loopback lo10 {
+             kernel-interface "vpptun10"
+         }
+         vxlan vxlan10 {
+             remote "10.10.10.2"
+             source-address "10.10.10.1"
+             vni "10"
+         }
+     }
+     kernel-interfaces vpptun10 {
+         address "10.10.0.10/24"
+     }
+     settings {
+         interface eth1 {
+             driver "dpdk"
+         }
+         interface eth2 {
+             driver "dpdk"
+         }
+     }
+ }
