DGS-3600 Series Layer 3 Managed Gigabit Ethernet Switch
Priority (0-7)
This parameter is specified to re-write the 802.1p default priority previously set in the Switch, which
is used to determine the CoS queue to which packets are forwarded to. Once this field is specified,
packets accepted by the Switch that match this priority are forwarded to the CoS queue specified
previously by the user.
Replace priority
−
Tick the corresponding check 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.
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.
Group ID (1-4)
This field displays the mirror group’s identity.
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
This field allows the user to modify the protocol used to configure the Access Rule Table;
depending on which protocol the user has chosen in the Access Profile Table.
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 ticked 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 beginning and end of the port list
range are separated by a dash. For example, 3 specifies port 3. 2-4 specifies the range of ports
from 2 to 4.
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
and
156249
or
No Limit
. The default
setting is
No Limit
.
Time Range
Tick 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 pull-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
