Trunk configuration between Catalyst C9300 x MS Switches family

[AugustoCL]

Hello everyone!

I am using for the first time two stacked Catalyst switches working with Meraki Cloud based software.
This will be my Core Switch to concentrate all uplinks to other remote MS switches.

Well,
The default allowed VLAN configuration for Catalyst is "1-1000" and for MS switches it is "all", so I have a VLAN mismatch.
What is the best option in this case?
Set the remote MS port to 1-1000 like in Catalyst?
Or it doesn't matter and we can keep it as it is:

I just specify the vlans that I need for the trunk

Also, that Catalysts don't support port profiles yet so the Catalyst and the connecting MS port both need to be configured identically (MS without a port profile)

It will work fine as long as you don't use any VLANs in the 1001+ range.  If you just want all VLANs going between the switches then your suggestions of 1-1000 is a good one.

As has been stated above, there's no issues if you're using VLANs in the 1-1000 range.

That said, it's a good practice to specify the VLAN's that you actually use into an explicit allow list, matched on both sides of the trunk.

Thanks guys!!
You are all right and I will keep the settings identical on both sides. Regardless of which one I choose. 🙂
