Can I associate one non-standard port with multiple protocol parsers



E.g. If a customer has one non-standard port that handles Telnet and one other protocol that ExtraHop parses then can we use protocol classification to associate two different parsers with that port so ExtraHop can parse the traffic?


I have seen that done before with success. I also made some specific inquiries about this and was told that it should work. There is some associated overhead with checking a flow for multiple protocols, but it is better than not getting classification.

That being said I was also told not to get clever and set all the protocol parsers to check all ports.
