Ok, so this means in case of doubt always prefer the RFC instead of “just the reserved protocol” specified in iana?

I often have the problem to specify which protocol a port uses. For example while defining the ACL in Section 12 Task 3, matching TACACS. The PG tells to use tcp eq 49 but when I check the port numbers on iana ( HYPERLINK "http://www.iana.org/assignments/port-numbers"; http://www.iana.org/assignments/port-numbers) I see that there is also a udp port reserved for that. So how do you do that if you are not sure? Just configure two statements matching both, udp and tcp? Regards Roger No virus found in this outgoing message. Checked by AVG.
