3. For SNAP: Valid value in this case also is comprised of two different
sub-values.
a. OUI: OUI (Organizationally Unique Identifier) is value in format of
xx-xx-xx where each pair (xx) in string is a hexadecimal value
ranges from 0x00-0xff.
b. PID: If the OUI is hexadecimal 000000, the protocol ID is the
Ethernet type (EtherType) field value for the protocol running on top
of SNAP; if the OUI is an OUI for a particular organization, the
protocol ID is a value assigned by that organization to the protocol
running on top of SNAP.
In other words, if value of OUI field is 00-00-00 then value of PID will be
etype (0x0600-0xffff) and if value of OUI is other than 00-00-00 then valid
value of PID will be any value from 0x0000 to 0xffff.
Group Name
A valid Group Name is a unique 16-character long string for every entry which
consists of a combination of alphabets (a-z or A-Z) and integers(0-9).
Note: special character and underscore(_) are not allowed.
