A Cisco Nexus Series interface has entered an errdisabled state with the error message DCX-No ACK in 100 PDUs. What causes this error?
DCX-No ACK in 100 PDUs
DCBX uses a sequence-based Control Sub-TLV acknowledgement exchange between the switch and the host/CNA. The interface is error-disabled after the switch fails to receive the expected acknowledgement from the host for 100 PDUs.
