Frame Type:
Frame Type can have one of the following values:
1.
Ethernet
2.
LLC
3.
SNAP
NOTE:
On changing the frame type field, the valid
value of the following text field will vary depending on
the new frame type you selected
.
Value:

selected from the preceding Frame Type selection menu.
Below are the criteria’s 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
-
0xfff0.
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
-

-

3.
For SNAP:

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 the value of OUI field is 00
-
00
-
00, then the value
of PID will be etype (0x0600
-
0xffff). If the value of OUI is other than
00
-
00
-
00, then the valid value of PID will be any value from 0x0000
to 0xffff.
Group Name:
