Protocol-based VLAN
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:
Object Description
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.
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 between
0x0000 and 0xffff.
Group Name A valid Group Name is a 16-character long string, unique for every entry, which consists of a
combination of alphabets(a-z or A-Z) and integers(0-9).
Note: Special characters and underscores (_) are not allowed.
