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
