Public bug reported: Hi,
Per the Intel community [1], for Intel X710 controllers, the NIC is meant to handle LLDP directly. Unfortunately, this doesn't play well with lldpd: | hloeung@cumulus:mgmt:~$ net show lldp | grep swp24 | swp24 10G Trunk/L2 37383638-3530-5A43-3238-333330423954 Unknown It is known in upstream lldpd[2] with a fix proposed to work around this by disabling handling of LLDP in the NIC[3]. Can we please backport this to Focal? The suggested workaround is: | for i in $(sudo ls /sys/kernel/debug/i40e); do | echo lldp stop | sudo tee /sys/kernel/debug/i40e/${i}/command | done [1]https://community.intel.com/t5/Ethernet-Products/X710-dropping-LLDP-frames/m-p/348508 [2]https://github.com/lldpd/lldpd/issues/372 [3]https://github.com/lldpd/lldpd/commit/a74fd8ca9c02fc0eb81f7a219b2bb657cac25ca2 ** Affects: lldpd (Ubuntu) Importance: Undecided Status: Fix Released ** Affects: lldpd (Ubuntu Focal) Importance: Undecided Status: New ** Affects: lldpd (Ubuntu Hirsute) Importance: Undecided Status: New ** Affects: lldpd (Ubuntu Impish) Importance: Undecided Status: Fix Released ** Affects: lldpd (Ubuntu Jammy) Importance: Undecided Status: Fix Released ** Also affects: lldpd (Ubuntu Impish) Importance: Undecided Status: New ** Also affects: lldpd (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: lldpd (Ubuntu Jammy) Importance: Undecided Status: New ** Also affects: lldpd (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: lldpd (Ubuntu Impish) Status: New => Invalid ** Changed in: lldpd (Ubuntu Jammy) Status: New => Invalid ** Changed in: lldpd (Ubuntu Impish) Status: Invalid => Fix Released ** Changed in: lldpd (Ubuntu Jammy) Status: Invalid => Fix Released ** Description changed: Hi, Per the Intel community [1], for Intel X710 controllers, the NIC is meant to handle LLDP directly.
