I have to stop and start a p:poll in JSF using some conditions... I am able to do that by putting the poll in a panelgrid and making the panelGrid rendered... I thought its working since the pollOperationStatus is not called after I made the panelGrid rendered false... When I show it , it restarts as well..
But there is a network call still firing ; which messes up many things ;How to deal it?

  So you actually mean that you can start the poll, stop the poll but it then keeps on doing network calls? And if you start it again it is doing duplicate calls?

Primefaces 7 Documentation says:

Poll can be started and stopped using client side api; Or bind a
boolean variable to the stop attribute and set it to false at any
arbitrary time.

In your case this would be in javaScript:

PF('poller').stop(); or PF('poller').start();

Or bind a boolean bean property the the stop attribute of the p:poll:

<p:poll stop="#myBean.stopPoller" interval="8" widgetVar="poller" autoStart="true"
 listener="#myBean.pollOperationStatus"
 update=":#p:component('newServerID') :#p:component('mypollform')" />

Also beware that component IDs in update attribute are separated by space, not comma.

  From the documentation you refer to: "Multiple components to update can be specified with providing a list of ids separated by a comma, whitespace or even both." PrimeFaces ajax differs here from basic JSF, but it is better to adhere to the basic JSF. (off-topic: almost 3000 rep... close votes coming close)
