What names or naming conventions do you use for your networking equipment ?

I have recently moved to an organisation where they seem to use wacky names for each device.

For instance small branch site (about 10 users) has a Cisco 2960x labeled and the site core switch.

So we apparently have like 300 core switches ranging from 2960x to 9Ks which seems stupid to me.

Personally I would like to just call them by vendor and item number and label the the device production or test.

Then rely on our network documentation to depict what roles each device play.

What do you guys use ?
