You can check this link:

Hi Francesco,

Thanks for your input.

As per link..4145 device supports 1024 sub-interfaces in overall. Actually I want to know how many sub-interfaces we can create for per port(example eth1/1) and port-channel.

we are having a requirement to create more than 400 sub-interfaces in per port and per port-channel(bundle) in 4145.

I just saw i pasted the wrong link.

Here is the correct one: https://www.cisco.com/c/en/us/td/docs/security/firepower/630/configuration/guide/fpmc-config-guide-v63/interfaces_for_firepower_threat_defense.html#concept_783AD17947BF4743BCA7D6B3C47C829E

Max global is 1024 and i don't think there's a limit per port.
