CHAPTER 4
WEB OPERATION & CONFIGURATION
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).
SIP (32 LSB):
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:
CoS:
If a frame matches the QCE, it will be put in the queue corresponding to the specified CoS class.
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.
