Hello Community I face an issue which i cannot resolve. 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. Some information from DC support of the swith config: # sh interface po1113 switchport Name: port-channel11 13 Switchport: Enabled Switchport Monitor: Not enabled Operational Mode: trunk Access Mode VLAN: 1 (default) Trunking Native Mode VLAN: 1 (default) Trunking VLANs Allowed: 300,390,398-399 Voice VLAN: none Extended Trust State : not trusted [COS = 0] Administrative private-vlan primary host-association: none Administrative private-vlan secondary host-association: none Administrative private-vlan primary mapping: none Administrative private-vlan secondary mapping: none Administrative private-vlan trunk native VLAN: 1 Administrative private-vlan trunk encapsulation: dot1q Administrative private-vlan trunk normal VLANs: none Administrative private-vlan trunk private VLANs: none Operational private-vlan: none Unknown unicast blocked: disabled Unknown multicast blocked: disabled Please advise as I'm almost stuck.
