• Value
• Group Name
Valid value that can be entered in this text field depends on the option
selected from the preceding Frame Type selection menu.
Below is the criteria for three different Frame Types:
1. For Ethernet: Values in the text field when Ethernet is selected
as a Frame Type is called etype. Valid values for etype ranges
from 0x0600-0xffff
2. For LLC: Valid value in this case is comprised of two different
sub-values.
a. DSAP: 1-byte long string (0x00-0xff)
b. SSAP: 1-byte long string (0x00-0xff)
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.
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.
