Hi!

 

I created a hardware switch interface type, with 2 physical ports, and cannot delete it.

It's grayed out, even if I try to disable them.

 

How is it possible to delete them, please?

 

TY

    Go to GUI Interfaces view. At the end of the table, there is a Ref. column. I assume the number of reference is not 0. Then you can't delete it. If you click the number, you can see where it is referred. You need to remove the references first to be able to delete any objects not only an interface.

      When I click on the reference number, it shows no matching entries under Current Usage. So what would those references be?

      That happened to me too. I don't remember how I fixed those cases but it means you removed all references already. It might take a reboot if you don't see anything even in CLI "show | grep -f <OBJECT_NAME>".

      Hi, 

      When creating a hardware switch, it's common to also set up a VLAN, address object, and DHCP server. To delete the hardware switch interface, first check the VLAN under that switch to see the reference count.

      If the reference shows dependencies, click to view them. Items with a reference count of "0" can be deleted. However, for address objects that match subnets, you need to go to the Address section under Policies and Objects, search for the specific address, and delete it.

      After removing any necessary address objects, go back to the VLAN interface and check the reference count again. If it’s "0," you can delete the VLAN and reuse the interface.

      To add to this, make sure you check DHCP servers and make sure one wasn't created. I found in my case I had set the setting for the interface to do dhcp but even once i turned it off the dhcp server was still sitting on the firewall.

      These guys are leading you astray , go in to Addresses and delete the interface . It will be under policy and objects > addresses as well as interface list .
