Protocol to Group Mapping Table
This page allows you to add new protocols to Group Name (unique for each Group) mapping entries
and to see and delete already-mapped entries for the switch.
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 values of the following text field will vary depending on
the new frame type you select.
Value
Valid values that can be entered in this text field depend on the option selected from the the preceding
Frame Type selection menu.
Below are the criteria for three different Frame Types:
For Ethernet:
Values in the text field when Ethernet is selected as a Frame Type are called etypes.
Valid values for etypes range from 0x0600 to 0xffff.
For LLC:
Valid values in this case are composed of two different sub-values.
a.
DSAP
: 1-byte long string (0x00-0xff)
b.
SSAP:
1-byte long string (0x00-0xff)
For SNAP:
Valid values in this case also are composed of two different sub-values.
a
OUI:
OUI (Organizationally Unique Identifier) is value in the format of xx-xx-xx, where each pair (xx)
in the string is a hexadecimal value that ranges from 0x00 to 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.
