Hi
I have a DC architecture with a pair of Nexus 7010's running 3 VDC's (Core/Aggregation/Enterprise). I have at the edge Nexus 5548's which connect to back to the Aggregation VDC. Also connecting back to the Aggregation VDC is an IBM Blade Chassis which has a Nexus 4001i in slots 7 and slot 9. These blade servers are running ESXi 4.0 and are mapped to the Nexus 4001 blade switch.
I had set up the Native VLAN as VLAN 999 which connects up to the ESXi host and I am trunking up multiple VLANS for the Virtual Machines.
The problem I have is that VM's in all VLANS except the ESXi host VLAN (VLAN 10) cannot see their default gateway, and I suspect that there is an issue with the VLAN tag going up to the ESXi host. I have read enough documentation to suggest that this is where the issue is.
My Nexus 4001 interface configuration is below
interface Ethernet1/1
switchport mode trunk
switchport trunk native vlan 999
switchport trunk allowed vlan 10,30,40-41,60-62,90,96,999
spanning-tree port type edge trunk
speed auto
The Aggregation VDC on the Nexus 7010 is the default gateway for all these VLANS.
I also noted that the Nexus 5000 and Nexus 7000 supports the command vlan dot1q tag native command yet the Nexus 4000 doesn't seem to support this. Any assistance would be useful
Thanks
Greg
