Chapter 4 Managing the Cisco HSI
Gapping
Note We strongly recommend that you set all packages to log level 0x0000 in a live network. Set them to
higher levels only when you debug on an offline network.
Setting Logging Levels
The set-log MML command dynamically alters the log level setting during the execution of the system.
However, the set-log MML command does not affect the logging level of any current MML processes.
For more information about the set-log command, see
Appendix A, “MML User Interface and Command
Reference.”
Note The enabling of logging severely impacts HSI performance. We recommend the HSI be running at less
than 2 calls per second when you enable logging. Logging will be automatically disabled when the HSI
enters overload level 3. You can reenable logging when the HSI exits overload.
RADVision Logging
The Cisco HSI application provides the capability (through MML) to initiate RADVision logging. The
contents of the resultant log file are not under the control of the Cisco HSI application.
Use the radlog MML command to start and stop RADVision logging. RADVision logging can be
directed to a file or into the standard logging output. For information about this command, see
Appendix A, “MML User Interface and Command Reference.”
Gapping
The gapping level can be set from 0 to 100 percent. From 0 to 99 percent, the call type (normal or
priority) is checked against the gapping level call status type. At 100 percent gapping, all calls are
gapped regardless of call type.
Setting Gapping
To activate call gapping, complete the following steps:
Step 1 Determine the direction of the call to be gapped:
• Incoming (inc) for calls originating from the H.323 network
• Outgoing (otg) for calls originating from the PSTN Gateway (PGW 2200)
• Both (both) for calls originating from either side
Step 2 Determine what type of calls are to be gapped:
• Normal calls (nonpriority calls)
• All calls
Step 3 Determine the percentage of calls to be gapped. The percentage can range from 0 to 100 percent. If
100
percent is selected, all calls are gapped, regardless of the type of call.
