Problem with NW teaming on c7000 with bl460

[Tstvetan]

Hello,
i have c7000 with 4 bl460. When teaming is ON, the newrok drops. When I disable one of the team cards everything is Ok again, until reboot, then same situation. I try all teaming modes, same situation, with only one card, or one team user disabled everything is OK.
Any idea?

Tstvetan, can you provide more details on this issue, whats the OS? whats the NCU version? Are you seeing Team Disconnected or only 1 team member? Is there any log on the windows events?

Hi, what do you mean the network drops?
Do you have any spanning tree or similar activated on the switch ports?

Hi, 4 blades running on 2K3 x64 R2, Firmware is 2.51 from May 28 2009. There is no any error in win event or in OA. Network is showing "conncted", and looks like everything is OK. but ping stops, alcc connections terminate, util disable/enable one of the team users, then everything is OK, util reboot.

Hi,
The other information we REALLY need is

1. What Interconnect modules are you using, and which IC bays are they installed in?

2. What Mezz cards (if any) do you have installed on your blades.

3. How have you set up the NIC Teaming on your blades, i.e. which NIC ports make up the teams?

Dave.
