I am starting to do more work via the CLI such as security rules. How can I check if a service object already exists using the CLI? And if it does not exist how do I add the service object to I can use it in my security rule?
If I try to add a service object and the name already exists will the PAN warn me and not all that to be input?
What if the protocol and port are already represented by another service object name?
so I'll indirectly answer this question and hopefully this will rock your world.
will display the candidate configuration, but by default, it's in XML format. so _outside_ of configure mode (for some reason), run the following command:
set cli config-output-format set
that will set the show output to set commands. now when you run show in configure mode, you will see each entry in a clear, easy to use CLI syntax. You can actually use the service parameter to see just the services.
admin@PA-220# show service set service service-https-mgmt protocol tcp port 4443 set service service-ssh protocol tcp port 22 set service service-plex protocol tcp port 32400
not only does this show you all the custom services (note the predefined service-http and service-https are not displayed), but it gives you the exact syntax to add additional ones via the CLI. If you have a lot of services, you can also supplement the command with | match <filter> at the end so it shows only matching service objects.
admin@PA-220# show service | match "tcp port 22" set service service-ssh protocol tcp port 22
so to answer your questions, if you create a service object with the same name as an existing one, it will let you and just overwrite the existing object's values. if you create a new service object with a different name but the same protocol/port, it also well let you.
my sage advice is to keep it simple and develop an administrative policy so that service objects are simply named for their protocol/port, such as tcp_22. using app names like I have before helps read better, but unless I also plan to have a service-sftp object, I'm just going to create a lot of unncessary 'duplicate' objects.
