Re: stp max number of instance

I'm going to assume it depends on what kind of switch you're talking about. Different switches have different capabilities.

In the case of a Cisco Catalyst 3560 switch: Up to 1024 VLANs and up to 128 spanning-tree  instances per switch are supported.

is there a way to find those info per switches model?

Re: stp max number of instance

Of course, all I did was a google search for "Catalyst 3560 spanning-tree instances" and the first link was the product Data Sheet for the 3560.

https://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps5528/product_data_sheet09186a00801f3d7d.html

You can substitute the 3560 for whatever switch you're wondering about.

You can find Data Sheets for whatever switch you want here:

It's usually contained with the data sheet. Start here -

Switches

then select the switch you are interested in, scroll down the page and near the bottom will be a link for the data sheet.
