LocalDirector dynamic-feedback command settings

Use the LocalDirector

dynamic-feedback command options as described in this section

to optimize your LocalDirector setup.

Note: Do not use the dynamic-feedback-pw command. ClusterCATS does not support

secure DFP hosts.

• dynamic-feedback -timeout — sets timeout to a value larger than the update

frequency so LocalDirector does not prematurely terminate the connection with the

cluster because of inactivity. We recommend that you set the value to at least twice

the update frequency.

• dynamic-feedback -retry

Use the dynamic-feedback -retry — sets the retry value to zero to ensure that

LocalDirector continues connection attempts to the ClusterCATS DFP agent in the

event of a lengthy period of system unavailability.

For more information, see Cisco’s LocalDirector Command Reference.

To integrate ClusterCATS with the Cisco LocalDirector:

1 Review all considerations before continuing with this procedure.

2 Complete the LocalDirector basic hardware installation and configuration. Ensure

that you have defined an IP address for LocalDirector, and that the LocalDirector

network interfaces are configured correctly. You can use the

ping utility to test

network connectivity.

3 Create a virtual server (www.yourcompany.com) in LocalDirector that corresponds to

the cluster.

4 In LocalDirector, bind explicit (real) servers participating in the cluster with the

virtual server.

5 Use LocalDirector’s

dynamic-feedback command to specify the IP addresses of each

explicit server (cluster member) and port number that each server will use to listen for

DFP requests from LocalDirector. The port number must be the same as the DFP

Agent Listen Port configured in step 9.

For example:

dynamic-feedback 192.168.64.22:9124 retry 0 attempts 30 timeout 60

The DFP protocol will connect to server 192.168.64.22 at port 9124. If the

connection between LocalDirector and the server is closed for any reason,

LocalDirector will attempt to reconnect, every 30 seconds, indefinitely. LocalDirector

will close the connection if it is inactive for 60 seconds.

For more information, see “LocalDirector dynamic-feedback command settings” on

page 93.

6 Open the ClusterCATS Explorer and select a cluster.
