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 DCSP. 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 FTP URL Lookup String field, enter the URL of the file to be downloaded from the FTP server.
The URL has to be in the format:
ftp://user:passwd@servername/dir/file.
If it is anonymous ftp server, use the format:
ftp://servername/dir/file.
Caution While defining an FTP operation, you have to specify the hostname/ip address of the FTP server. The
hostname you specify has to be DNS resolvable. If you execute an ftp operation without a
DNS-resolvable hostname, then all the routers on which the ftp collectors are configured would reboot.
IPM validates the format of the FTP string that you enter in the FTP URL Lookup String field and
displays appropriate error messages if any of the variables you enter in the URL string is incorrect.
IPM checks the syntax and also checks whether:
• If userinfo (if specified) is in the format user:pwd.
