Chapter 3 Provisioning the Cisco HSI

H.323 Stack Configuration

Refer to the RADVision H.323 Protocol Stack Programmer’s Guide for definitions of each of the

RADVision parameters.

The parameter name is based on the ASN.1 paths, but in some cases the parameter name has been

shortened for convenience. For example, “capabilities” has been shortened to “caps.”

The case of the parameter name reflects exactly the ASN.1 definitions, but case is not important to MML

configuration.

Nonprovisionable Data

The parameters in Table 3-5 cannot be altered through MML commands.

DISKUSAGELIMIT Represents a percentage of disk occupancy.

The application continually polls the system for disk occupancy, and

if the percentage rises above the limit set by DISKUSAGELIMIT, the

LOW_DISK_SPACE alarm is raised.

DISKUSAGELIMIT has a default value of 95 percent. The value

range is 0–100, inclusive. When dynamically provisioned, the

parameter DISKUSAGELIMIT, if not set within that range, is set to

the default value (95) and the CONFIGURATION_ FAILURE alarm

is raised.

RegFailureReleaseCause

This parameter specifies the Q.850 release cause, which the HSI uses

after the HSI fails three times to register to a gatekeeper.

This parameter is assigned a value in the range 1—127
