4.6.13 Protocol-based VLAN
This page allows you to add new protocols to Group Name (unique for each Group) mapping entries as well as allow you to see
and delete already mapped entries for the switch. The Protocol-based VLAN screen in Figure 4-6-19 appears.
Figure 4-6-19: Protocol to Group Mapping Table Page Screenshot
The page includes the following fields:
Object Description
• Delete To delete a Protocol to Group Name 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, valid value of the following text field will
vary depending on the new frame type you select.
• Value
Valid value that can be entered in this text field depends on the option selected
from the preceding Frame Type selection menu.
Below is 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 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.
• Group Name A valid Group Name is a unique 16-character long string for every entry which
consists of a combination of alphabets (a-z or A-Z) and integers (0-9).
Note: special character and underscore (_) are not allowed.
