Thanks Anshul,
Does the "Per-priority-pause status: Rx (Inactive), Tx (Active)" mean PFC is Tx enabled? This is an iSCSI setup and as I understand it, Nexus does not support the iSCSI TLV for DCB at this time. We would certainly want to disable this PFC if it is enabled, but if this will not cause issues then we can overlook it.
I only have the show tech-support currently, but I have requested the output of the command you requested. Would the following suffice? It shows Tx and Rx disabled, however the interface is receiving DCBX frames. I will post the output of the requested as soon as I receive it.
`show lldp dcbx interface Ethernet1/21 `
