Re: [vpp-dev] Up to date documentation for working with vpp_api 2.0.0?
@Pim, Thank you! I saw the VPPApiClient Class, just didn't know how to use it. Your example should give me good direction going forward. - Dave -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] Up to date documentation for working with vpp_api 2.0.0?
Hi Dave,
That documentation is out of date, and the class is VPPApiClient. Here's a
quick demo script for you:
from vpp_papi import VPPApiClient
from vpp_papi import VppEnum
import os
import fnmatch
import sys
vpp_json_dir = '/usr/share/vpp/api/'
# construct a list of all the json api files
jsonfiles = []
for root, dirnames, filenames in os.walk(vpp_json_dir):
for filename in fnmatch.filter(filenames, '*.api.json'):
jsonfiles.append(os.path.join(root, filename))
vpp = VPPApiClient(apifiles=jsonfiles, server_address='/run/vpp/api.sock')
vpp.connect("test-client")
r = vpp.api.show_version()
print('VPP version is %s' % r.version)
iface_list = vpp.api.sw_interface_dump()
for iface in iface_list:
print(iface)
if iface.link_duplex ==
VppEnum.vl_api_link_duplex_t.LINK_DUPLEX_API_UNKNOWN:
## Do something with this match
pass
To your other question, vppctl is the debug CLI. You cannot issue API calls
with that tool. Take a look at *vat2*, which can send an API message to VPP
and print its reply, or use the generated API client *vpp_api_test.*
Hope that helps, groet,
Pim

Re: [vpp-dev] Up to date documentation for working with vpp_api 2.0.0?
Also "acl_add_replace" does not work directly from vppctl ``` sudo vppctl acl_add_replace ? unknown input `acl_add_replace ?' ``` However when I am in VAT I can run the command. Am I missing a module in VPP? ``` $ sudo vppctl show plugin Plugin path is: /usr/lib/x86_64-linux-gnu/vpp_plugins Plugin Version Description 1. ioam_plugin.so 22.10-rc0~60-g55050c31c Inbound Operations, Administration, and Maintenance (OAM) 2. lldp_plugin.so 22.10-rc0~60-g55050c31c Link Layer Discovery Protocol (LLDP) 3. urpf_plugin.so 22.10-rc0~60-g55050c31c Unicast Reverse Path Forwarding (uRPF) 4. http_static_plugin.so 22.10-rc0~60-g55050c31c HTTP Static Server 5. l3xc_plugin.so 22.10-rc0~60-g55050c31c L3 Cross-Connect (L3XC) 6. mdata_plugin.so 22.10-rc0~60-g55050c31c Buffer metadata change tracker. 7. ping_plugin.so 22.10-rc0~60-g55050c31c Ping (ping) 8. tlsopenssl_plugin.so 22.10-rc0~60-g55050c31c Transport Layer Security (TLS) Engine, OpenSSL Based 9. avf_plugin.so 22.10-rc0~60-g55050c31c Intel Adaptive Virtual Function (AVF) Device Driver 10. l2tp_plugin.so 22.10-rc0~60-g55050c31c Layer 2 Tunneling Protocol v3 (L2TP) 11. pppoe_plugin.so 22.10-rc0~60-g55050c31c PPP over Ethernet (PPPoE) 12. pnat_plugin.so 22.10-rc0~60-g55050c31c Policy 1:1 NAT 13. srv6am_plugin.so 22.10-rc0~60-g55050c31c Masquerading Segment Routing for IPv6 (SRv6) Proxy 14. crypto_native_plugin.so 22.10-rc0~60-g55050c31c Intel IA32 Software Crypto Engine 15. flowprobe_plugin.so 22.10-rc0~60-g55050c31c Flow per Packet 16. dpdk_plugin.so 22.10-rc0~60-g55050c31c Data Plane Development Kit (DPDK) 17. det44_plugin.so 22.10-rc0~60-g55050c31c Deterministic NAT (CGN) 18. hs_apps_plugin.so 22.10-rc0~60-g55050c31c Host Stack Applications 19. adl_plugin.so 22.10-rc0~60-g55050c31c Allow/deny list plugin 20. acl_plugin.so 22.10-rc0~60-g55050c31c Access Control Lists (ACL) 21. hsi_plugin.so 22.10-rc0~60-g55050c31c Host Stack Intercept (HSI) 22. crypto_openssl_plugin.so 22.10-rc0~60-g55050c31c OpenSSL Crypto Engine 23. dslite_plugin.so 22.10-rc0~60-g55050c31c Dual-Stack Lite 24. ikev2_plugin.so 22.10-rc0~60-g55050c31c Internet Key Exchange (IKEv2) Protocol 25. svs_plugin.so 22.10-rc0~60-g55050c31c Source Virtual Routing and Forwarding (VRF) Select 26. vrrp_plugin.so 22.10-rc0~60-g55050c31c VRRP v3 (RFC 5798) 27. tracedump_plugin.so 22.10-rc0~60-g55050c31c Streaming packet trace dump plugin 28. nsim_plugin.so 22.10-rc0~60-g55050c31c Network Delay Simulator 29. dns_plugin.so 22.10-rc0~60-g55050c31c Simple DNS name resolver 30. mss_clamp_plugin.so 22.10-rc0~60-g55050c31c TCP MSS clamping plugin 31. builtinurl_plugin.so 22.10-rc0~60-g55050c31c vpp built-in URL support 32. cnat_plugin.so 22.10-rc0~60-g55050c31c CNat Translate 33. perfmon_plugin.so 22.10-rc0~60-g55050c31c Performance Monitor 34. dhcp_plugin.so 22.10-rc0~60-g55050c31c Dynamic Host Configuration Protocol (DHCP) 35. rdma_plugin.so 22.10-rc0~60-g55050c31c RDMA IBverbs Device Driver 36. vmxnet3_plugin.so 22.10-rc0~60-g55050c31c VMWare Vmxnet3 Device Driver 37. wireguard_plugin.so 22.10-rc0~60-g55050c31c Wireguard Protocol 38. igmp_plugin.so 22.10-rc0~60-g55050c31c Internet Group Management Protocol (IGMP) 39. nat_plugin.so 22.10-rc0~60-g55050c31c Network Address Translation (NAT) 40. tlsmbedtls_plugin.so 22.10-rc0~60-g55050c31c Transport Layer Security (TLS) Engine, Mbedtls Based 41. memif_plugin.so 22.10-rc0~60-g55050c31c Packet Memory Interface (memif) -- Experimental 42. crypto_ipsecmb_plugin.so 22.10-rc0~60-g55050c31c Intel IPSEC Multi-buffer Crypt
[vpp-dev] Up to date documentation for working with vpp_api 2.0.0?
Hello, I am new to working with the vpp-api. I tried reading the documentation found here ( https://wiki.fd.io/view/VPP/Python_API ) , however I am unable import "VPP" from "vpp_papi". Looking at the source for "/usr/lib/python3/dist-packages/vpp_papi/vpp_papi.py", there is no class called "VPP". I am a total newb working with vpp-api, can someone point me in the right direction on how I can get started? Main goal is to create an ACL, add ACE's, change them, and remove them.

[vpp-dev] The position of ipsec4-output-feature in the arc ip4-output
Hi All, When I test VPP ipsec with version 2110, I found the node ipsec4-output-feature is the last node in ARC ip4-output. So when use SPD in ipsec. if there is big packet that was fragment when output . When the fragment packet was input ipsec4-output-feature node. the other packet expect the first fragment packet will not match SPD policy ,so the packet was droped. 00:12:05:665867: ip4-lookup fib 0 dpo-idx 7 flow hash: 0x UDP: 10.10.10.15 -> 10.10.10.2 tos 0x00, ttl 128, length 1548, checksum 0x0cbd dscp CS0 ecn NON_ECN fragment id 0x UDP: 500 -> 500 length 1528, checksum 0x94f4 00:12:05:665868: ip4-rewrite tx_sw_if_index 0 dpo-idx 7 : ipv4 via 10.10.10.2 GigabitEthernet0/13/0: mtu:1500 next:4 flags:[features ] ee9d5c8281695e0001010800 flow hash: 0x05dc : 4500060c80110cbd0a0a0a0f0a0a0a0201f401f405f894f43eb4a54c 0020: 65ce89de80feb8853ee4fe402e20232105f0240005d4 00:12:05:665869: ip4-frag IPv4 mtu: 1500 fragments: 2 next: 0 00:12:05:665878: ip4-rewrite tx_sw_if_index 1 dpo-idx 7 : ipv4 via 10.10.10.2 GigabitEthernet0/13/0: mtu:1500 next:4 flags:[features ] ee9d5c8281695e0001010800 flow hash: 0x : ee9d5c8281695e0001010800450005dc060020007f11e7ec0a0a0a0f0a0a 0020: 0a0201f401f405f894f43eb4a54c65ce89de80feb8853ee4fe402e20 tx_sw_if_index 1 dpo-idx 7 : ipv4 via 10.10.10.2 GigabitEthernet0/13/0: mtu:1500 next:4 flags:[features ] ee9d5c8281695e0001010800 flow hash: 0x : ee9d5c8281695e0001010800454406b97f110ccc0a0a0a0f0a0a 0020: 0a02cb4be59b66a472db88e5a88133f298724b594b7624391727117e 00:12:05:665880: ipsec4-output-feature spd 2 policy 17 spd 2 policy -1 00:12:05:665882: error-drop rx:local0 00:12:05:665883: GigabitEthernet0/13/0-output GigabitEthernet0/13/0 IP4: 00:00:5e:00:01:01 -> ee:9d:5c:82:81:69 UDP: 10.10.10.15 -> 10.10.10.2 tos 0x00, ttl 127, length 1500, checksum 0xe7ec dscp CS0 ecn NON_ECN fragment id 0x0600, flags MORE_FRAGMENTS UDP: 500 -> 500 length 1528, checksum 0x94f4 00:12:05:665884: drop ip4-frag: packet fragmented 00:12:05:665884: GigabitEthernet0/13/0-tx GigabitEthernet0/13/0 tx queue 0 buffer 0x91ca7: current data -14, length 1514, buffer-pool 0, ref-count 1, trace handle 0x6 ip4 l3-hdr-offset 0 PKT MBUF: port 65535, nb_segs 1, pkt_len 1514 buf_len 2176, data_len 1514, ol_flags 0x0, data_off 114, phys_addr 0x62272a40 packet_type 0x0 l2_len 0 l3_len 0 outer_l2_len 0 outer_l3_len 0 rss 0x0 fdir.hi 0x0 fdir.lo 0x0 IP4: 00:00:5e:00:01:01 -> ee:9d:5c:82:81:69 UDP: 10.10.10.15 -> 10.10.10.2 tos 0x00, ttl 127, length 1500, checksum 0xe7ec dscp CS0 ecn NON_ECN fragment id 0x0600, flags MORE_FRAGMENTS UDP: 500 -> 500 length 1528, checksum 0x94f4 Can we move the node ipsec4-output-feature to the first node in ARC ip4-output ?
