Thank you for your feedback
IPv4 filters can be used to loop back traffic or set up a traffic policy based on specific characteristics such as IPv4 Header settings, ICMP settings and VLAN settings.
To set up an IPv4 filter job
Access the page Commission ▶ Jobs.
Set all common configuration job settings, as described in "Creating Configuration Jobs in GUI Mode" and in "Creating Configuration Jobs Using Data Sets".
Select IPv4 filter in the left pane. The IPv4 filter tab is displayed.
Complete all fields in the IPv4 filter tab as required. For more information on specific parameters, see the table below.
Use the Add
button or Duplicate 
button to add IPv4 filters as required.
button or Duplicate Note: When duplicating a row, always select the row to duplicate before clicking the Duplicate
button.Click Apply, then click Close.
Click the Refresh
button to refresh the user interface.

Filter General
| Parameter | Description |
|---|---|
| Name | A unique name used to identify the filter. |
IPv4 Settings
| Parameter | Description |
|---|---|
| Source | Checkbox to enable or disable use of the IPv4 source address and mask in the filter. |
| IPv4 source Mask source | The source address and mask. These two values are combined to specify the source of packets. To specify a particular IP address as the source, set the IPv4 address and leave the default mask value (255.255.255.255). To specify a subnet as the source, specify the IP address and a mask. Only the bits specified by the mask are used. The other bits are ignored. Note: Filtering source or destination IP addresses that are assigned by Dynamic Host Control Protocol (DHCP) can be problematic. It is recommended that you only specify static or reserved IP addresses in a filter. Otherwise the filter must be updated manually whenever the addresses change. |
| Destination | Checkbox to enable or disable use of the IPv4 destination address and mask in the filter. |
| IPv4 destination Mask destination | The destination address and mask. These two values are combined to specify the destination of packets. To specify a particular IP address as the destination, set the IPv4 address and leave the default mask value (255.255.255.255). To specify a subnet as the destination, specify the IP address and a mask. Only the bits specified by the mask are used. The other bits are ignored. Note: Filtering source or destination IP addresses that areassigned by Dynamic Host Control Protocol (DHCP) can be problematic. It is recommended to only specify static or reserved IP addresses in a filter, otherwise the filter must be updated manually whenever the addresses change. |
Ethernet Header Settings
| Parameter | header |
|---|---|
| TTL | Checkbox used to enable or disable using TTL (Time-To-Live). |
| TTL | TTL value. |
| ECN | Checkbox used to enable or disable using ECN (Explicit Congestion Notification). |
| ECN | ECN value. Specify either 0 or 3. |
| Header Length | Checkbox used to enable or disable using the header length. |
| Header Length | The header length. Value expressed in 32-bit words. Specify a value in the range of 5 to 15. |
| Protocol | Double-click in this field to change the value. Either select a protocol from the drop-down list or enter a port number (decimal value) manually. Common protocols:
|
| Custom | The port number expected by the custom protocol. Note: This parameter is valid only if the Protocol parameter is set to Custom. |
| VLAN stack size | Double-click in this field to change the value. Allows you to filter based on the number of VLAN tags in the packet. |
VLAN and VLAN-in-VLAN Settings
| Parameter | Description |
|---|---|
| Ethertype | The VLAN Ethernet Type may be one of the following:<UL |
| CFI/DEI | The Canonical Format Indicator (CFI) or the Drop Eligibility Indicator (DEI). This value should always be set to zero for connections to Ethernet switches. CFI is used to ensure compatibility between Ethernet type networks and Token Ring type networks. If a frame received at an Ethernet port has a CFI set to 1, the frame should not be forwarded as-is to an untagged port. In the context of bandwidth regulation, DEI can be used to carry the frame color. When set to 0, the frame is green; when set to 1, the frame is yellow. |
| Priority Condition | Double-click in this field to select an operator to be used with the Priority Min or Priority Max field. VLAN priority allows provisioning CoS prioritization using the standard 802.1Q priority tag. Interpreting the priorities is based on the carrier's equipment and administrative policies. The valid operator types are:
|
| Priority Min | The priority minimum value. Acceptable values range from 0 to 7. |
| Priority Max | The priority maximum value. Acceptable values range from 0 to 7. |
| Operator | Double-click in this field to select an operator to be used with the ID Min or ID Max field. The VLAN ID used to filter traffic. The valid operator types are:
|
| ID initial | The VLAN ID minimum value. Acceptable values range from 0 to 4,095. |
| ID last | The VLAN ID maximum value. Acceptable values range from 0 to 4,095. |
DSCP/IP Precedence
| Parameter | Description |
|---|---|
| Type | The DSCP/IP type may be one of the following:
|
| Condition | The DSCP/IP precedence operator. The valid operator types are:
|
| ID initial | The DSCP/IP precedence minimum value. DSCP range: 0 to 63 IP precedence range: 0 to 7 |
| ID last | The DSCP/IP precedence maximum value. DSCP range: 0 to 63 IP precedence range: 0 to 7 |
ICMP Settings
| Parameter | Description |
|---|---|
| ICMP type | Enables the use of ICMP. You must specify the ICMP message type to be matched by this filter. Note: These settings are only valid when Protocol is set to ICMP (1). Some well-known ICMP types are:
|
| ICMP code | Enables the use of the ICMP code. The ICMP code value. |
UDP/TCP Port Settings
| Parameter | Description |
|---|---|
| Source port | Enables the use of the UDP/TCP source port. The source port used to match this rule. Note: This setting is valid only when the Protocol parameter is set to TCP (6) or UDP (17). |
| Destination port | Enables the use of the UDP/TCP destination port. The destination port used to match this rule. Note: These settings are only valid when Protocol is set to TCP (6) or UDP (17). |
