Hi Parthiban,
I'm thinking this is a comms/networking/ issue.
From the problem switch I cannot receive any EDP Details. From other switches EDP displays but NOT for the problem switch.
I think I need to work out why my switch is not communicating on the network.
Must be an IP issue or similar.
I have a seperate post logged at:

I will however go to the problem device, restart EDP and sync the Stack Config just to ensure that any changes have been replicated.
