Fixed In Version: openvswitch2.10-2.10.0-27.el7fdn
Doc Type: If docs needed, set a value
Doc Text:
Cause: Several versions of OVS including 2.10 ignore updelay and downdelay settings on bonds. Consequence: The updelay and downdelay parameters will be ignored, and the default value will be used. Workaround (if any): Although there is no workaround, the default updelay and downdelay values should work for most environments, and there have so far been no reports of undesirable behavior. Result: The updelay and downdelay settings will have no effect until OVS is upgraded to a new version.

Description Timothy Redaelli 2018-11-06 10:19:21 UTC
+++ This bug was initially created as a clone of Bug #1646707 +++

Description of problem:
Open vSwitch has a bug in the LACP bond implementation, such that the updelay and downdelay parameters are ignored. This bug was recently fixed, but is not yet available in any version of OVS in OSP.

Version-Release number of selected component (if applicable):
OVS 2.10

How reproducible:

Steps to Reproduce:
1. Configure an OVS bond with balance-tcp mode (LACP) and updelay or downdelay configured in the options

Actual results:
The updelay and downdelay settings are ignored.

Expected results:
The updelay and downdelay settings should be respected.

Additional info:
The default settings seem to be working, since we haven't received any customer reports of any issues. However, this bug may come up, so we should have an errata for this issue. We are unlikely to backport these changes in OVS to previous versions of OSP, so this issue will remain until we use a newer version of OVS that includes this patch:
