Hyper-V VS M6220 (VLAN configuration)

Hi to all,

I have a M1000e with 4 M6220 switch. 2 of 4 M6220 are dedicated to iSCSI traffic, other 2 for network. M6220 switches are not stacked.

I have 6 M610 blades (1-6)

A2 and B2 M6220 switches have same configuration.

Port 1-6 connected to Blades

Port 17 connected to Cisco 2960S switch (vlan 101)

Port 18 connected to Cisco 2960 switch (vlan 100)

M6220 firmware version 4.2.2.3

Cisco 2960 firmware 12.2 (55)

Problem.

Windows 2012 with Hyper-V is installed on all 6 blades.

A2 and B2 network are teamed on each blade.

Win2012 management OS is configured on vLan 101.

From all blade, I'm able to ping the default gateway for vLan 101.

All VMs configured on vLan 101 are able to ping the default gateway.

 

If I configure VMs on vLan 100 I'm not able to ping the vLan gateway. I'm able to ping other VMs on same vLan even if other VMs runs on different host.

All VMs are connected to same virtual switch (Hyper-V layer 2), they are configure in different vLan only.

Why? What I missed?

 

Thanks a million
David
