How to rename interfaces in mikrotik using regexp?

Question

Mikrotik

Good afternoon. I'm interested in the following question.
I want to write a script to configure the default router group.
Also it is necessary to rename interfaces.
for example: list of interfaces ehter1, ether2,... rename to lan1, lan2...
RouterOS 7.1.3
I understand that through set but I can't implement it. Knowledge is not enough.

Answer 1

No need to rename interfaces. During the update, special effects will occur if the interface names do not match the expected ones.
Use comments to sign interfaces.
PS
You also don't need to edit the default IPsec policies, PPP profiles, Wi-Fi keys, and so on, you need to copy them and change them to suit your needs or create new ones from scratch, for the reasons described above.
