I know but that is the full output that this particular model of 9K gives you for sub-interfaces, below is the parent Interface:

So we have recently installed a N9K-C9348GC-FXP and utilised the sub-interface command with encapsulation dot1q which we know is supported.
However when testing this circuit we are finding that iperf is only giving us about 50.3Mbps on a 1G circuit over the 10G NNI Interface. Our circuit provider as done intrusive testing up to our cabinet and shown that the port is capable of 10G and the dot1q vlan is capable of 1G
We are using a Single Mode Fibre on the 10G-LR SFP (Recently changed for another new cable)
But whilst our SMARTNET is being dealt with wondering if anyone has seen this behaviour or might know why this is so?
