Protocol to Group
This page allows you to add new Protocol to Group Name (each protocol can be part of only
one Group) mapping entries as well as allow you to see and delete already mapped entries for
the switch.
The displayed settings are:
Delete
To delete a Protocol to Group Name map entry, check this box. The entry will be deleted from the switch
during the next Save.
Frame Type
Frame Type can have one of the following values:
1.
Ethernet
2.
LLC
3.
SNAP
Note: When 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 the three different Frame Types:
1.
Ethernet:
Value in the text field when Ethernet is selected as a Frame Type is called etype.
Valid values for etype range between 0x0600 and 0xffff
2.
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.
SNAP:
Valid value in this case is also comprised of two different sub-values.
a.
OUI:
OUI (Organizationally Unique Identifier) is a parameter in the format of xx-xx-xx
where each pair (xx) in the string is a hexadecimal value ranging between 0x00 and 0xff.
b.
PID:
PID (Protocol ID). If OUI is hexadecimal 000000, then the protocol ID is the Ethernet
type (EtherType) field value for the protocol running on top of SNAP; if 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.
