Step 3: ETM® System Configuration
3.
The
Heartbeat Interval
specifies how often the Span contacts the
Management Server. The default heartbeat interval is 60 seconds. It is
strongly recommended that you do not change this setting. More
frequent heartbeats increase network load and do not increase
reliability. However, a shorter heartbeat interval decreases the time
until the Management Server becomes aware of a lost connection in
some network configurations.
The
Firewall
tab provides settings specific to ETM Policy processing.
To set Firewall tab settings
1.
In the
Span Configuration
dialog box, click the

tab.

Select the
Allow
Call
Terminations
check box to enable calls to be
terminated; clear the

Call
Terminations
check box to prevent
any calls from being terminated on this Span.
The
Terminate
Policy
setting applies to enforcement of terminate
Rules in Policies, manual termination via the
Call Monitor
, and
terminate commands issued via ETM Commands. If this check box is
not selected, no calls can be terminated on this Span, regardless of the
setting in a Rule's
Action
field or user permissions. By default, the
check box is cleared.
