creating and removing port objects and object-groups

[Eric R. Jones]

Hello all, We are preparing for DNAC deployment and I need to open up ports in the FW. We have 2 HA pairs of FTD 2130's managed by FMC. We are running 7.2.4 and I plan to create Network Objects and Port Object-groups.

So I shall name the port object-group DNAC_Ports. I plan to add pre-existing port objects to the new group.These pre-exsiting port objects are already used in the FW and I have never had to remove a port object-group in the past.  Should I need to remove this port object-group in the future will the underlying pre-existing port objects that are used in other object-groups throw an error once I disassociate the DNAC_Ports object-group from being used anywhere? I want to say no, and firmly believe it won't but I'm checking to be sure. I've not read anything that states there's an issue.

Why you need to merge both object group?

I was planning to create an object-group to add the already existing objects.

Guess I didn't explain it as well as I thought, sorry about that.

So  have objects for ssh, dns, ntp, etc... I was planning to add all those to an object-group. Should I need to remove that group all I need to do is remove that group from any use and then delete it correct? the objects within that group shouldn't matter correct?
