Hello
I face an issue which i cannot resolve for almost month even with the help of intel support.
I have:
Intel Server System R1208GL4DS with buildin I350 4 ports inet adapter
OS: Windows Server 2008 R2
NIC drivers ver 18.4 (PRO set with ANS)
Data Center provides ieee802.3ad dynamic aggregation teaming connection, It uses 2 ports on my server (0 and 3)
DC uses Cisco Nexus switches
SpanningTreeProtocol is ON and cannot be switched off by DC.
Problem:
One of the adapters suddenly goes on standby state and doesnot pass traffic.
As the result the whole connectivity to server and to services I use stuck at that moment.
There is only one way to resolve is to restart server or restart whole team by changing the team properties.
Nic properties:
flow control off
ofloads off
rss off
Team:
I have tried to change everything playing with any property within nic or team. No luck.
Please advise as I'm almost stuck.
Thank you.
