    Step 2: Check the reachability by typing the following commands

    Follow the below steps to perform SLP sync with CSSM.

    Step 1: We must sync on the device side.

    b. Type the command “license smart sync all”.

    Step Result: Pushes the usage report to On-prem.

    Step 2: Perform On-prem SLP network/manual sync to get the ACK file against the usage reports received from the device.

    Step 3: Once the ACK is received in SSM On-Prem, wait for 24hrs to get this installed in the Device.
