Hi,

New install with 3 x Hyperscale X nodes in this config.

Cisco UCSC240M6 and Cisco UCS VIC 15427 
The VIC 15427 configured as physical nic mode which creates 4 x vNics om the server.

Links are up ( after turning off FEC)  and Bond created with LACP.

All looks good from the network side  but we cannot reach anythine else on the network, not even default gateway.

Analysing the switch traffic the ping request gets to the gateway and reply is sent back to the server but the packet is not picked up.

Anyone with this configuration that have had similar problems?  And if so possible solution?

Hi,

We are using the Bonded VLAN topology.

resolved the problem now with the latest BIOS,CIMC and VIC MLOM Firmware in Cisco HUU package version 4.3.5.250001.

So it seems like a firmware bug on the VIC 15427.
