Explanation
The message indicates that the switch has received an unknown EAPS super domain (ESD) PDU from
another switch.
The PDU type field in the ESD PDU should have the one of the following values:
• 1 for ESD segment health PDU
• 2 for ESD loop detect PDU
• 3 for ESD flush notify PDU
Action
Capture the PDU packet and verify the pdutype field.
If you find unsupported values in the PDU, then check the switch from which the packet originated.

after the comparison.
