xStack® 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 Select this option to instruct the Switch to replace the DSCP value (in a packet that meets the (0-63) 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 (1156249) 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. Figure 6- 13. Access Rule Table window 317
