Parameter descriptions:
Frame Type:
Frame Type can have one of these values:
1. Ethernet
2. LLC
3. SNAP
N
OTE
:
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:
Valid value that can be entered in this text field depends on the option selected from the preceding
Frame Type selection menu. Below are the criteria for three different Frame Types:
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
LLC
: Valid value in this case is comprised of two different sub-values.
DSAP
: 1-byte long string (0x00-0xff)
SSAP
: 1-byte long string (0x00-0xff)
SNAP
: Valid value in this case also is comprised of two different sub-values.
OUI
: Organizationally Unique Identifier, in the format xx-xx-xx where each pair (xx) is a
hexadecimal value ranges from 0x00-0xff.
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.
