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 Target Port field, enter the TCP port number for the target device to use when sending a response
to a connection request. Valid values are 1 to 65535. The default setting is 3000.
You can specify any port number, well known or otherwise, on any IP host, Cisco or non-Cisco, as long
as someone is listening on that port on the target.
• If this target uses the SA Agent, make sure you configured it as a Cisco SAA Responder target on
the Target Configuration window.
• If you mistakenly configured it as an IP target, and you specify a Target Port that is not well known
(that is if you specify a port number greater than 1024), IPM considers the target an IP device rather
than an SA Agent device. In such as case, IPM does not enable the SA Agent Control protocol. As
a result, the collector cannot connect to the target and no data is collected.
Step 7 Click Add.
IPM adds the newly defined operation to the IPM database.
Step 8 Click Close to close the Configuration window.
