What this means is when I create a virtual interface on the adapter, that interface is actually created and appears as a local interface on the Fabric Interconnect (FI), whether it’s a vNIC which appears as a Veth port on the FI or a vHBA which appears as a Vfc interface. ![]() The Interface to which Veth749 is bound to is Ethernet 1/1/2 which equates to Chassis1 Server 2 (you can ignore the middle value) the description field also confirms the location and virtual interface name on the server (eth0)Īs you know, (having read my blog post on “Adapter FEX”:-) ) the M81KR “PALO” adapter is actually a mezzanine fabric extender just like the IO Module (FEX) in the Chassis. ![]()
