Using the Policy Manager
EPICenter Reference Guide
506
The status icon displayed in the upper right corner of the Policy Manager indicates that the
configuration is occurring (see “Configuration Status” below for details).
If auto configuration is disabled , you must explicitly perform the configuration process. In this
mode, policies can be created or modified and saved, but they are not configured on the network until a
directed configuration (
Config or Config All ) is done.
NOTE
It is strongly recommended that you disable auto configuration while editing multiple policy definitions or changing
the precedence of policies, especially if they involve the “blackhole” profile (deny access). With auto configuration
enabled, each change is configured on the network immediately as the individual policy is changed, possibly before
the appropriate precedence relationships have been established. This could cause serious network connectivity
problems. After all changes have been made, you can re-enable auto configuration so that all configuration changes
will be made only after the correct precedence relationships have been established.
Configuration Status
When an automatic configuration operation occurs the configuration status icon, shown at the upper
right corner of the Policy Manager, displays an animated status indication of the progress of the
configuration.
●
First, the Policy Manager must compute the access list and QoS rules based on your policy
definitions. This is indicated by an animated display of the following graphic:
●
Second, the Policy Manager applies the computed policies to the device (those policies that are valid,
and not in conflict with any other policies). This is indicated with another animated display:
When the configuration is complete, the icon returns to its quiescent state. You can use the ACL Viewer
to view the results of the policy configuration.
Directed Configuration
You can configure policies on a selected device or group of devices, or on all devices known to the
EPICenter server in one operation.
●
From the ACL Viewer, you can configure policies on selected devices.
Select the device or group in the component tree, and click the
Config button. .
●
To configure all policies on all devices at once, click the Cfg All button . You can do this from
either the Policies View or from the ACL Viewer.
In either case, a pop-up window appears asking for confirmation of the configuration.
Click Yes to proceed with the configuration, or No to cancel the operation.
A message window (shown in Figure 265 ) pops up to show you the progress of the configuration.
