BL860 i4 LOM lan* Inbound Errors=1904, nwmgr and netstat -ni output can see this Inbound Errors error information, the clear count is 0, and increases to about 300 every day. There is no error in the system log, OA or iLO.

Hi,

1.Are you seeing "Inbound errors" on only one LOM port or multiple?
2.You mean to say, even if count is cleared it increases by 300 counts everyday?
3.Is there any Virtual connected in this environment. If yes, check if there are any errors with this downlink/uplink?
4.What is this interface/IP used for (backup, mgmgt etc)?
5.Have you tried resetting the interface (after clearing counts) and see if Inbound errors re-occur?
6.Please share below commands output for that affected LOM.

# nwmgr -q info -c lanX (replace X with LAN number)
# nwmgr -g --st mib -c lanX (replace X with LAN number)
# netstat -ni

Thanks

Hi,

Thank you for the details.

1.Clear LAN port stats for LAN 9
2.Reset the interface once (perform this during scheduled window or downtime)
3.Monitor further for any discards/errors.

If still Inbound error occurs, then this requires further validation  (LAN port <-> 10Gbe switch <-> network switch). Would suggest log a support ticket.

Thanks.
