Appendix A MML User Interface and Command Reference

prov-sta

prov-sta

The prov-stacommand establishes a provisioning session. The data files are copied from the source version to the destination version.

prov-sta::srcver=version,dstver=version

Syntax Description

 

srcver=version

Selects a specific configuration version as the source for configuration

 

 

 

 

 

 

changes. The srcver variable represents a directory that exists in

 

 

 

 

 

 

$GWBASE/var/prov/. In place of the configuration version, you can also

 

 

 

 

 

 

enter:

 

 

 

 

 

 

new—Specifies a new default session configuration; no existing source

 

 

 

 

 

 

configuration is used.

 

 

 

 

 

 

active—Selects the active configuration as the source for configuration

 

 

 

 

 

 

changes.

 

 

 

 

 

 

 

 

 

 

 

 

 

dstver=version

Specifies the output version directory for the configuration session results.

 

 

 

 

 

 

The dstver variable represents a directory stored in $GWBASE/var/prov/.

 

 

 

 

 

 

 

 

 

 

 

 

 

Usage Guidelines

 

If the source and destination filenames are the same, the new configuration overwrites the old

 

 

 

 

 

configuration. It is a good practice to copy an existing configuration instead of overwriting it so that you

 

 

 

 

 

can return to a known configuration if there are problems with the new one.

 

 

 

 

 

If the source provisioning session has not been verified, the message “Note: This provisioning session

 

 

 

 

 

has not been verified” is displayed, but the session starts normally.

 

 

 

 

 

If you try to start with a provisioning session that does not exist, an error is displayed, along with a list

 

 

 

 

 

of available sessions.

 

 

 

 

 

The MML command in the following example starts a provisioning session named nowt and creates a

Examples

 

 

 

 

 

 

new configuration named blah:

 

 

 

 

 

gw mml> prov-sta::srcver=nowt,dstver=blah

M DENY

 

 

 

 

 

 

 

 

The provisioning session called "nowt" does not exist.

 

 

 

 

 

The following configurations are available:

transit dave matt

 

 

 

 

 

 

 

 

The MML command in the following example starts a provisioning session and creates a new

 

 

 

 

 

configuration named ver1:

 

 

 

 

 

gw mml> PROV-STA::SRCVER="new", DSTVER="ver1"

M SUCC

 

 

 

 

 

 

 

 

Successfully started provisioning session "ver1" from "new".

 

 

 

 

 

The MML command in the following example starts a provisioning session, opens the existing

 

 

 

 

 

configuration named ver1, and overwrites that configuration:

 

 

 

 

 

gw mml> PROV-STA::SRCVER="ver1", DSTVER="ver1"

H.323 specifications

Cisco Systems H.323 is a set of standards designed for transmitting audio, video, and data over packet-switched networks. It is a critical technology that enables real-time communication and has become integral to the world of VoIP (Voice over Internet Protocol) and video conferencing applications. Originally developed by the ITU-T, H.323 has been widely adopted and implemented by Cisco Systems, allowing organizations to leverage reliable and scalable communication solutions.

One of the standout features of H.323 is its ability to support interoperability among varying equipment and platforms. This means that devices from different manufacturers can communicate seamlessly, which is vital in a diverse technical environment. H.323 does this by defining protocols that handle signaling, media transport, and control, ensuring that various systems can work together effectively.

Key technologies utilized within H.323 include H.225 and H.245 signaling protocols. H.225 is responsible for call setup and management, establishing communication between endpoints. In contrast, H.245 manages the negotiation of media channels, allowing devices to configure themselves based on the capabilities of each other. This adaptability is crucial for dynamic network conditions typical in VoIP applications.

Another defining characteristic of H.323 is its support for multiple types of multimedia communication, including point-to-point and multipoint calls. This flexibility supports everything from simple audio calls to complex videoconferencing setups, where many participants can share video and audio streams concurrently. Cisco enhances this capability through its hardware and software offerings, optimizing performance for conference calls.

H.323 also features robust error resilience mechanisms. This ensures that real-time data, which is typically sensitive to delays and losses, can be transmitted with minimal disruption. Moreover, it facilitates quality of service (QoS) implementation, allowing organizations to prioritize voice and video traffic over less critical data services, thereby improving the overall user experience.

In conclusion, Cisco Systems H.323 stands out as a comprehensive solution for real-time communication over packet-based networks. Its main features, including interoperability, multimedia support, and enhanced error resilience, position it as a relevant technology in both corporate and personal communication settings. As organizations continue to adopt cloud and hybrid communication models, H.323 remains a reliable backbone for ensuring connectivity and collaboration across diverse platforms.
