I looked all over the place and could never find a description of exactly what vet is...tcp or udp, although the RFC's (i think they were rfc1700) always had it listed, and in the official one, someone with initials 'cxl1' always initialed it. However, I could never find exactly what it is.

I looked at the doc's that MsMittens provided and I think they are just describing the rmon protocol for and the vettcp reference is just the MIB info for the RMON protocol:

vettcp PROTOCOL-IDENTIFIER
PARAMETERS { }
ATTRIBUTES { }
DESCRIPTION
"VET TCP"
REFERENCE
"TBD"
::= { tcp 78,
udp 78 }
Interestingly enough...the reference is 'TBD' which I assumes to be determined...maybe it was never formalized but the reserved port remains? The reference would normally supply the RFC number describing it... The description field also in the rest of the MIB's was pretty detailed, but only contains the name...so I am thinking that it probably was never formally defined?
