Description
Delete:
To delete a protocol to group mame 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 - The valid value of
the following text field will vary depending on the new frame
type you selected.
Value:
The 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.
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 the value of OUI field is 00-00-00, then 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.
