xStack DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch
specified, packets accepted by the Switch that match this priority are forwarded to the CoS
queue specified previously by the user.
replace priority − Click the corresponding box to re-write the 802.1p default priority of a packet to
the value entered in the Priority field, which meets the criteria specified previously in this
command, before forwarding it on to the specified CoS queue. Otherwise, a packet will have its
incoming 802.1p user priority re-written to its original value before being forwarded by the Switch.
For more information on priority queues, CoS queues and mapping for 802.1p, see the QoS
section of this manual.
Class
Entering a value between 0 and 255 will instruct the Switch to examine the class field of the IPv6
header. This class field is a part of the packet header that is similar to the Type of Service (ToS)
or Precedence bits field of IPv4.
Flow Label
Configuring this field, in hex form, will instruct the Switch to examine the flow label field of the
IPv6 header. This flow label field is used by a source to label sequences of packets such as non-
default quality of service or real time service packets.
Source IPv6
Address
The user may specify an IP address mask for the source IPv6 address by entering the IP
address mask, in hex form.
Destination IPv6
Address
The user may specify an IP address mask for the destination IPv6 address by and entering the
IP address mask, in hex form.
Port
The Access Rule may be configured on a per-port basis by entering the port number of the
switch in the switch stack into this field. When a range of ports is to be configured, the Auto
Assign check box MUST be clicked in the Access ID field of this window. If not, the user will be
presented with an error message and the access rule will not be configured. The port list is
specified by listing the lowest switch number and the beginning port number on that switch,
separated by a colon. Then the highest switch number and the highest port number of the range
(also separated by a colon) are specified. The beginning and end of the port list range are
separated by a dash. For example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch
number 2, port 4. 1:3 - 2:4 specifies all of the ports between switch 1, port 3 and switch 2, port 4
− in numerical order. Entering all will denote all ports on the Switch.
Rx Rate
Use this to limit Rx bandwidth for the profile being configured. This rate is implemented using the
following equation: 1 value = 64kbit/sec. (ex. If the user selects an Rx rate of 10 then the ingress
rate is 640kbit/sec.) The user many select a value between 1- 156249 or No Limit. The default
setting is No Limit.
Time Range
Click the check box and enter the name of the Time Range settings that has been previously
configured in the Time Range window. This will set specific times when this access rule will be
implemented on the Switch.
To view the settings of a previously correctly configured rule, click in the Access Rule Table to view the following screen:
