Switch > VLAN Management > Protocol‐based VLAN > Protocol to Group
This page lets you 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.
Delete: To delete a Protocol to Group Name map entry, check this box. The entry will be deleted from the switch
during the next Apply.
Frame Type: Frame Type can have one of these 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 from 0x0600 to 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. In other words, if the value of OUI field is 00‐00‐00 then the value of PID will be etype
(0x0600‐0xffff) and if the value of OUI is other than 00‐00‐00 then valid values of PID will be any value
0x0000 ‐ 0xffff.
