Replace DSCP
(0-63)
Select this option to instruct the Switch to replace the DSCP value (in a packet that meets the
selected criteria) with the value entered in the adjacent field.
VLAN Name
Allows the entry of a name for a previously configured VLAN.
Source IP
Source IP Address – Enter an IP Address mask for the source IP address.
Destination IP
Destination IP Address – Enter an IP Address mask for the destination IP address.
DSCP (0-63)
This field allows the user to enter a DSCP value in the space provided, which will instruct the
Switch to examine the DiffServ Code part of each packet header and use this as the, or part of
the criterion for forwarding. The user may choose a value between 0 and 63.
Protocol
Specifies that the Switch will examine the Protocol field in each packet and if this field contains
the value entered here, apply the appropriate rules.
• user define − Enter a hexadecimal value in the form 0x0-0xfffffff that will identify the
protocol to be discovered in the packet header.
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
(1-156249)
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 Settings window. This will set specific times when this access rule
will be implemented on the Switch.
Counter
Tick the check box and use the drop-down menu to employ the Counter that will count the
packets identified with this rule. Users must note that if the Counter is employed in the ACL Flow
Meter function, the Counter will automatically be disabled here, regardless of this setting.
To view the settings of a previously correctly configured rule, click in the Access Rule Table window to view the following
