connect 2 GbE2c-L2/3 to one cisco: no ping between bl460c servers

[it61066]

Hello,

I have two c7000 with the following configs:

- Enc1: two GbE2c L2/3 switches, 2 bl870c, 2 bl680c, 2 bl460c
- Enc2 (testing): one GbE2c, one bl870c, 2 bl680c

I have configured the GbE2c switches for ufd and teaming. To distribute the load between switches, we have configured the team in failover mode with preference order: a group of servers with preference on GbE2c-Bay1 and others on Bay-2.

Both GbE2c switches are connected to the same cisco switch (one only). We have only one Vlan, one subnet. My problem is:

Servers with preference NIc on Bay-1 cannot ping those on Bay-2 but all clients connected to the cisco switch can ping / connect to any server inside the enclosure.

Any help please?

Thanks.
