Thank you for responding Damien,
My understanding for " aaa accounting update newinfo periodic 2880" command is that 'newinfo' enables the switch to send any accounting updates if any changes have been observed and the 'periodic 2880' is used to set the duration (2 days) after which the updates would be sent.
Now consider a scenario, where the endpoints connected to a switch may not have any changes in cdp,lldp or dhcp attributes which does not trigger the switch to send any new updates to ISE due to which the session in ISE would be removed after 5 days.
So, why would Cisco recommend the "aaa accounting update newinfo periodic 2880" command rather than "aaa accounting update periodic 2880"?

The command "aaa accounting update newinfo periodic 2880" accomplishes two necessary things.
If you use the command "aaa accounting update periodic 2880" without the "newinfo" keyword, then you lose the immediate updates that are part of item one above. This command would only perform updates at 2880 minutes.
