1.3.6.1.4.1.18.3.5.3.16.1.1.11.1.12
List of upper layer protocol types (e.g., UDP is 16,
TCP is 6, ICMP is 58) of the packet payload.
If non-null, the octet string contains one or more
3-tuples of this form:
1 octet: protocol type (zero means 'any protocol')
2 octets: value of the first 16 bits of
upper-layer payload (zero means 'any value')*
2 octets: value of the next 16 bits of
upper-layer payload (zero means 'any value')*
For UDP and TCP protocol the first 16 bits of payload
correspond to the source port number and the next 16
bits of payload correspond to the destination port number.
*If the protocol type is ICMP(58), the first 2-octets
value identifies the ICMP Type and second 2-octets value
should be set to 0.
A null string also means 'match any protocol'.
