To delete a Protocol to Group Name map entry, check this box. The entry
will be deleted on the switch during the next Save.
Frame Type
Frame Type can have one of the following values:
1. Ethernet
2. LLC
3. SNAP
Note: On changing the Frame type field, valid value of the following text
field will vary depending on the new frame type you selected.
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:
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.
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.
