Inserting a global filter

To insert a global filter:

1. From the Device Manager menu bar, choose IP Routing > Filter.

The Filter dialog box opens with the Filters tab displayed.

2. Click Insert.

The Filters, Insert Filters dialog box opens.

You can use this dialog box to select the criteria for global filters and DiffServ filters.

3. In the Type field, select Global.
4. In the DstAddr field, type the destination IP address (optional).
5. In the DstMask field, type the destination subnet mask (optional).
6. In the SrcAddr field, type the source IP address (optional).
7. In the SrcMask field, type the subnet mask (optional).
8. Type the name of the filter (optional).
9. Set the ProtocolType: ignore (none), icmp, tcp, or udp (optional).
10. Type the source port, and select the source option (equal, not equal, greater, less, or ignore).

This step is applicable only if a TCP or UDP protocol was selected.

11. Type the destination port, and select the destination option (equal, not equal, greater, less, or ignore).

This step is applicable only if a TCP or UDP protocol was selected.

12. Set the following parameters (optional):

­

Mirror

­	TcpConnect

13. In the Mode field, select the mode (useDefaultAction, forward, drop, or forwardToNextHop).
14. In the Set StopOnMatch option box, click to enable or disable.
15. In the MatchIcmpRequest option box, click to enable if you want matching on ICMP request packets performed.
16. In the MatchIpFragment option box, click to enable if you want matching on fragmented IP packets performed.
17. In the EnableStatistic option box, click to enable if you want statistics for this filter.
18. Select the DiffServModifyIeee8021PEnable option box if you want to modify the IEEE 802.1p field.
    
    

    Note: When you enable a traffic filter to modify either the DSCP or the IEEE 802.1p bits, the traffic filter also modifies the other value based on the corresponding value in the QoS ingress tables.

    
    
19. If you do not want to use the IEEE 802.1p value automatically assigned based on the QoS Table, you can enter the modify value of the IEEE 802.1p field.
20. In the DiffServModifyDscpEnable option box, click to enable if you want to modify the DiffServ codepoint field.
21. In the DiffServModifyDscp field, you can type the value of the DiffServ codepoint if you do not want to use the DSCP value automatically assigned based on the QoS Table.
22. Specify the DiffServTrafficProfileId of the traffic profile, if any, to be associated with this filter.
23. Click Insert.

The new filter is displayed in the Filters tab. If you changed the DiffServ filter fields, that information is displayed in the DiffServ tab.
