Step 4 In the Name field, enter a descriptive name to assign to the operation. In the Description field, you can enter a brief description of the operation, including its purpose.

Step 5 Select the IP QoS Type as IP Precedence or DSCP. The IP QoS Settings values change based on your IP QoS Type selection.

•If you have selected IP QoS Type as IP Precedence, select the IP QoS Settings value from the drop-down. The value you select sets the priority for the HTTP request packet. The default setting is 0 (no priority). This option sets the ToS bits in the IP packet.

•If you have selected IP QoS Type as DSCP, select the desired IP QoS Settings value from the drop-down. The value you select defines the packet priority and is based on the DSCP RFC standards.

Step 6 In the URL Lookup String field, enter the Website URL to use for the HTTP request.

IPM validates the format of the HTTP string that you enter in the URL Lookup String field.

•The URL that you enter should be in the http://host[:port][/path[?searchpart]] format.

•The hostname should contain only alphanumeric characters, ‘.’ and ‘-’.

•The port number should be greater than 0 and less than 65536.

If you specify the path in the URL string, the next two characters that follow a ‘%’ should be hexadecimal values. The maximum length of characters that you can specify in the URL String field is 255.

IPM displays appropriate error messages if any of the variables you enter in the URL string is incorrect.

You can clear the Download URL from Cache checkbox if you want the router to query the Website for the HTTP request. Select the checkbox if you want the source to search its cache for the Website and, if it is found, download it instead of querying the Website. The default setting is for this box to be cleared (query the Website).
