Trunk Allowed vlans question

[7mnRais]

Hello,

 In my work we distrubted the switches as :
2 Core Switch ---> 10 DS switches ---> 80 Edge switches

My question is:

Where to apply "switchport trunk allowed vlans", is it better to apply it on core, DS or both ?

Thanks

Both ends.

Hi

A good practice must be on both ends (trunks interfaces) as Leo mentioned but it could be configured on 1 end for example on the Core switch.
