[release-4.20] OCPBUGS-62602: configure-ovs: work around a Cisco switch issue #5321
Conversation
When a slave is detached from a bond (e.g. during NetworkManager reactivation) before LACP negotiation completes, some Cisco switches mishandle LACP packets with agg=0, and disable the port. To work around this, if a bond slave is UP and LACP is enabled, wait up to 5 seconds for both ends to reach the "collecting,distributing" state before reattaching the interface. If negotiation does not complete within this window, a warning is logged but configuration continues. Note: This is a switch error, and sending agg=00 is valid. This is a workaround that only hides the issue on affected hardware and may reduce system's fault tolerance. Signed-off-by: Xin Long <[email protected]>
