153. I40E VXLAN-GPE Support Tests¶

153.1. Prerequisites¶

The DUT has at least 2 DPDK supported I40E NIC ports:

Tester      DUT
eth1  <---> PORT 0
eth2  <---> PORT 1

Support igb_uio driver:

modprobe uio
insmod  ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
./usertools/dpdk-devbind.py --bind=igb_uio 04:00.0 04:00.1

153.2. Test Case 1: VXLAN-GPE ipv4 packet detect¶

Start testpmd:
```
# testpmd -c 0xf -n 4 -- -i
```

Add VXLAN-GPE packet type support in test pmd and enable verbose log:

testpmd> set fwd io
testpmd> set verbose 1
testpmd> port config 0 udp_tunnel_port add vxlan-gpe 4790

Send VXLAN-GPE packets to testpmd and check received packets:

scapy> pkt=Ether(dst="3C:FD:FE:A8:C8:20")/IP(src="18.0.0.1")/UDP(dport=4790,sport=43)/VXLAN(flags=12)/IP(src="10.0.0.1")
scapy> sendp(pkt1, iface="ens802f1", count=1)

Expected output from testpmd:

src=00:00:00:00:00:00 - dst=3C:FD:FE:A8:C8:20 - type=0x0800 - length=70 - nb_segs=1 - RSS hash=0x51ed6fc5 - RSS
queue=0x2 - hw ptype: L2_ETHER L3_IPV4_EXT_UNKNOWN TUNNEL_GRENAT INNER_L3_IPV4_EXT_UNKNOWN
INNER_L4_NONFRAG  - sw ptype: L2_ETHER L3_IPV4 L4_UDP  - l2_len=14 - l3_len=20 - l4_len=8
- VXLAN packet: packet type =24721, Destination UDP port =4790, VNI = 0 - Receive queue=0x2

153.3. Test Case 2: VXLAN-GPE tunnel remove test¶

After Test Case 1, delete the VXLAN-GPE packet type:

testpmd> port config 0 udp_tunnel_port rm vxlan-gpe 4790

Send VXLAN-GPE packets to testpmd and check the received packets

Expected result:

testpmd should treat the packet as a normal UDP packet

153.4. Test Case 3: Tunnel filter VXLAN-GPE support¶

Start testpmd with tunneling packet type to vxlan and disable receive side scale for hardware limitation:

# testpmd -c ffff -n 4 -- -i --disable-rss --rxq=4 --txq=4 --nb-cores=8 --nb-ports=2 --tx-offloads=0x8fff

Set rxonly packet forwarding mode and enable verbose log:
```
testpmd> set fwd rxonly
testpmd> set verbose 1
```

Add one new Cloud filter as table listed first:

testpmd> tunnel_filter add 0 11:22:33:44:55:66 00:00:20:00:00:01 192.168.2.2 1 vxlan-gpe imac-ivlan 1 3

Then send one packet and check packet was forwarded into right queue.
