PARAMETERS
These parameters are displayed:
◆ Frame Type – Choose Ethernet, LLC (Logical Link Control), or SNAP (SubNetwork
Access Protocol - RFC 1042) as the frame type used by this protocol.
◆ Value – Values which define the specific protocol type. The fields displayed depend on the
selected frame type:
Ethernet – EtherType value. (Range: 0x0600-0xffff; Default: 0x0800)
LLC – Includes the DSAP (Destination Service Access Point) and SSAP (Source
Service Access Point) values. (Range: 0x00-0xff; Default: 0xff)
SNAP – Includes OUI (Organizationally Unique Identifier) and PID (Protocol ID) values:
■ OUI – A value in the format of xx-xx-xx where each pair (xx) in the string is a
hexadecimal value in the ranges of 0x00-0xff.
■ 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 that of 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 the OUI field is 00-00-00, then value of the PID will be etherType
(0x0600-0xffff), and if value of the OUI is other than 00-00-00, then valid value of the PID
will be any value from 0x0000 to 0xffff.
◆ Group Name – The name assigned to the Protocol VLAN Group. This name must be a
unique 16-character long string which consists of a combination of alphabetic characters
(a-z or A-Z) or integers (0-9).
Note: Traffic which matches IP Protocol Ethernet Frames is mapped to the VLAN (VLAN 1
by default) that has been configured with the switch's administrative IP. IP Protocol
Ethernet traffic must not be mapped to another VLAN or you will lose administrative
network connectivity to the switch. If lost in this manner, network access can be regained
by using the Reset button to restore the factory default settings.
