Value
Valid value that can be entered in this text field depends on the option selected from the the preceding
Frame Type selection menu.
Below is the criteria for three different Frame Types:
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
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)
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.
