Public bug reported: Ubuntu 20.04 LTS dpdk 19.11.7-0ubuntu0.20.04.1
We are seeing issues with link status of ports as DPDK-bond members and those links suddenly go away and marked as down. There are multiple parameters that could cause this issue, but one of the suggestions we've got from a server vendor was that the following upstream patch would be required to support 25G AOC/ACC cables. https://github.com/DPDK/dpdk/commit/b1daa34614 (available for v21.05 onward) (todo: define a test case) [expected status] ---- dpdk-bond0 ---- bond_mode: balance-tcp bond may use recirculation: yes, Recirc-ID : 1 bond-hash-basis: 0 updelay: 0 ms downdelay: 0 ms next rebalance: 1691 ms lacp_status: negotiated lacp_fallback_ab: false active slave mac: 40:a6:b7:3e:4a:60(dpdk-d2cb784) slave dpdk-7272e20: enabled may_enable: true slave dpdk-d2cb784: enabled active slave may_enable: true [after sometime - links are lost] ---- dpdk-bond0 ---- bond_mode: balance-tcp bond may use recirculation: yes, Recirc-ID : 1 bond-hash-basis: 0 updelay: 0 ms downdelay: 0 ms next rebalance: 7267 ms lacp_status: configured lacp_fallback_ab: false active slave mac: 00:00:00:00:00:00(none) slave dpdk-7272e20: disabled may_enable: false slave dpdk-d2cb784: disabled may_enable: false ** Affects: dpdk (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1940957 Title: i40e: support 25G AOC/ACC cables To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpdk/+bug/1940957/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
