Does anyone know how I can configure flow control on an nx_nic (10G NIC) in ESXi?
I found this article: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1013413
However neither of those options seems to work:
~ # ethtool -A vmnic0 autoneg off
autoneg unmodified, ignoring
no pause parameters changed, aborting
~ # ethtool -A vmnic0 autoneg off rx on tx on
autoneg unmodified, ignoring
rx unmodified, ignoring
tx unmodified, ignoring
no pause parameters changed, aborting
~ # ethtool -A vmnic1 autoneg off rx on tx on
autoneg unmodified, ignoring
rx unmodified, ignoring
tx unmodified, ignoring
no pause parameters changed, aborting
And:
~ # esxcfg-module -s FlowControl=3,3 nx_nic
Unable to set module parameters the following params are invalid: FlowControl
Any ideas?
Based on the output it would suggest that flow control is enabled by default, however I wanted to double check that is actually enabled!
