Chapter 1 Configuring a Service Policy

Adding a Service Policy Rule for Through Traffic

Specify the address and subnet mask using prefix/length notation, such as 10.1.1.0/24. If you enter an IP address without a mask, it is considered to be a host address, even if it ends with a 0.

Enter any to specify any source address.

Separate multiple addresses by a comma.

c.In the Destination field, enter the destination IP address, or click the ... button to choose an IP address that you already defined in ASDM.

Specify the address and subnet mask using prefix/length notation, such as 10.1.1.0/24. If you enter an IP address without a mask, it is considered to be a host address, even if it ends with a 0.

f.(Optional) To specify a source service for TCP or UDP, click the More Options area open, and enter a TCP or UDP service in the Source Service field.

The destination service and source service must be the same. Copy and paste the destination Service field to the Source Service field.

g.(Optional) To make the rule inactive, click the More Options area open, and uncheck Enable Rule.

This setting might be useful if you do not want to remove the rule, but want to turn it off.

h.(Optional) To set a time range for the rule, click the More Options area open, and from the Time Range drop-down list, choose a time range.

To add a new time range, click the ... button. See the “Configuring Time Ranges” section on page 20-15in the general operations configuration guide for more information.

This setting might be useful if you only want the rule to be active at predefined times.

•Tunnel Group—Choose a tunnel group from the Tunnel Group drop-down list, or click New to add a new tunnel group. See the “Add or Edit an IPsec Remote Access Connection Profile” section on page 4-79in the VPN configuration guide for more information.

To police each flow, check Match flow destination IP address. All traffic going to a unique IP destination address is considered a flow.

•Destination Port—Click TCP or UDP.

In the Service field, enter a port number or name, or click ... to choose one already defined in ASDM.

•RTP Range—Enter an RTP port range, between 2000 and 65534. The maximum number of port sin the range is 16383.

•IP DiffServ CodePoints (DSCP)—In the DSCP Value to Add area, choose a value from the Select Named DSCP Values or enter a value in the Enter DSCP Value (0-63) field, and click Add.
