Control: Control field may contain command, response, or sequence information depending on
whether the LLC frame type is Unnumbered, Supervisory, or Information. By default, any is used. Select
specific to indicate a value (0x00 to 0xFF).
SNAP: SubNetwork Access Protocol can be distinguished by an OUI and a Protocol ID. (Options for PID: Any,
Specific (0x00-0xffff); Default: Any) 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
isother than 00-00-00, then valid value of the PID will be any value from 0x0000 to 0xffff.
IPv4:
Protocol: IPv4 frame type includes Any, TCP, UDP, Other. If “TCP” or “UDP” is selected, you might
further define Sport (Source port number) and Dport (Destination port number).
Source IP: Select source IP type. By default, any is used. Select “Specific” to indicate self-defined source
IP and submask format. The address and mask must be in the format x.y.z.w where x, y, z, and w are
decimal numbers between 0 and 255. When the mask is converted to a 32-bit binary string and read
from left to right, all bits following the first zero must also be zero
IP Fragment: By default, any is used. Datagrams sometimes may be fragmented to ensure they can pass
through a network device that uses a maximum transfer unit smaller than the original packet’s size.
DSCP: By default, any is used. Select “Specific” to indicate a DSCP value. Select “Range” to indicate a
range of DSCP value.
IPv6:
Protocol: IPv6 protocol includes Any, TCP, UDP, Other. If “TCP” or “UDP” is selected, you may need to
further define Sport (Source port number) and Dport (Destination port number).
Source IP: Select source IP type. By default, any is used. Select “Specific” to indicate self-defined source
IP and submask format.
DSCP: By default, any is used. Select “Specific” to indicate a DSCP value. Select “Range” to indicate a
range of DSCP value.
Action Parameters
Specify the classification action taken on ingress frame if the parameters match the frame’s content. The actions taken
include the following:
Class: If a frame matches the QCE, it will be put in the queue corresponding to the specified QoS class or placed in a
queue based on basic classification rules.
DPL: If a frame matches the QCE, the drop precedence level will be set to the selected value or left unchanged.
DSCP: If a frame matches the QCE, the DSCP value will be set to the selected one.
