- Prerequisites:
- Total 1 cases, 1 passed, 0 failed
- Case:
./usertools/dpdk-devbind.py -b igb_uio 05:00.0 05:00.1
1. Start the testpmd::
./testpmd -c 1ffff -n 4 -- -i --nb-cores=8 --rxq=4 --txq=4
--port-topology=chained
testpmd> set fwd rxonly
testpmd> set verbose 1
testpmd> start
2. Show port default RSS fuctions::
testpmd> show port 0 rss-hash
RSS functions:
ipv4-frag ipv4-other ipv6-frag ipv6-other ip
Send the ipv4-other packets with different src/dst ip address.
All the packets are distributed to all the four queues.
3. disable all RSS fuctions::
testpmd> flow create 0 ingress pattern end actions rss types none end / end
Flow rule #0 created
testpmd> show port 0 rss-hash
RSS disabled
Send the ipv4-udp packets with different src/dst ip address.
All the packets are distributed to queue 0.
Notes: only i40e support the command,
others don't support the command created.
4. enable RSS fuction with all RSS hash type::
testpmd> flow create 0 ingress pattern end actions rss types all end / end
Flow rule #1 created
testpmd> show port 0 rss-hash
RSS functions:
all ipv4-frag ipv4-tcp ipv4-udp ipv4-sctp ipv4-other ipv6-frag ipv6-tcp
ipv6-udp ipv6-sctp ipv6-other l2-payload ip udp tcp sctp
Send the ipv4-udp packets with different src/dst ip address.
All the packets are distributed to all the four queues.
