I was thinking about this issue many time when follow my cables to which and where it is goes.
as every body know anyone can change the ports name to something you understand it or refer to something you like to check it.
my suggestion is it will be great idea if we get physical name for each port that can not be changed . in other word
ether1 can be changed to WAN because it is logical name for port 1 at any mikrotik board
it will be great idea if the names become tow parts physical.logical so anyone like to change port name as our example he can change the logic part and the physical part will stack with that name like this ether1.WAN or eth1.wan
This will be great help to any one follow cables and he will now that each cable where it's goes even you change ports name
hope to get some one attention about that

Keep the default names and use comments for your own names.

yes. we can keep the default name and write what you like on comment but it will be nice if we can get both in one field. it will be more clear and more organized for me .

You would get mess in one field and loose two separate fields that can be used in script with advantage.

What about working with an alias like system? think symlink(hardlink) of the linux system...

But that would turn into a mess as well probably.. but it would be up to the user(administrator).

Be aware there is a field "default-name", which, to my knowledge, can't be changed and holds the original name:

Thanks friction,
finally I got logical answer. I did not know that there is default-name for ports. so it will be great if some one ask mikrotik support to show this field on winbox at port windows title or as field on General tab as default-name.
So, my next question why when transfer configuration from CCR1036-12G-4S to CCR1036-8G-2S+ you get mess in ports. suppose configuration based on that default name but each time when I transfer the configuration between this two routers I get eth1 at first router become eth5 as example. I hope mikrotik configuration based on this field so when you backup configuration and restore it to other RB you did not get mess as it happens like now.
Notes: I transfer configuration CCR1036-12G-4S to CCR1036-8G-2S+ and both updates with last frame ware.
anyone from mikrotik support can explain that for us and is it possible to show default-name on winbox.
thanks again friction for you replay

It should keep Ethernet/physical port naming conventions;

If I run the export command, the configuration of a given physical port looks like the following: This should ensure that when transferring the configuration the port naming should remain the same (at least for the interfaces they have in common).

All command output has been run on version 6.21.1.

Sorry I did not get you. do you mean that transfer configuration between two different routers based on port name ? do you mean changing names of port to default name before backup will ensure to keep the port identical in both said. is that true I think configuration must based on default-name and not on port name.
am I right ?

I don't understand the issue. You already gave the solution in your original post. Name the port "ether1-internet" and "ether2-customer"

Hi normis,
Thanks for joining to this issue . I am discussion with two issue here :-
1. It will be so nice if show default-name of port in winbox.
2. I faced mess ports configuration when try to transfer backup file from CCR1036-12G-4S to CCR1036-8G-2S+. so I was asking dose mikrotik depends on default-name when restore configuration file? if I restore CCR1036-12G-4S(router1) backup file to CCR1035-8G-2S+(router2) all eth1(router1) configuration will be transfer to eth1(router2)? based on default-name ? because I tried to transfer configuration between two routers and each time a get mess in ports configuration

new rotueros versions use "default name" for migration.
do not use backup files for moving config. always use "export" files. backup file is for restoring on the same device

Thanks ... This clear every thing
