F5OS-C 1.8.2
Opened: Feb 23, 2024 Severity: 2-Critical
If an LACP working member update is missed (either LACPD fails to send or switchd fails to reeive the update) control plane connectivity between the SC and blade may be lost.
Connectivity may be lost between CC, one or more blades and possibly loss of management port traffic if management ports are aggregated.
Any event giving LACP a reason to change the working members of a control plane aggregation (ie reboot/removal/instertion of a blade or CC).
Restart cc-switchd and cc-lacpd (in that order) on both SCs or reboot both SCs.
