Chapter 1 Cisco PGW 2200 Softswitch Platform Overview
Cisco PGW 2200 Softswitch Software Architecture
Agent Management Subsystem
The agent management subsystem (AMS) allows external client software or terminals to gain access to
the data in the Cisco PGW 2200 Softswitch. This subsystem supports the following functions:
• Configuration management—Enables you to add, delete, or modify parameters and resources on the
Cisco PGW 200 Softswitch so that it can perform its switching function. This data is stored locally
in data (.dat) files. This data is required to automate reconfiguration after a process failure.
• Alarm management—Reports and clears alarms generated by Cisco PGW 2200 Softswitch
processes.
• Performance measurement management—Reports and clears metrics that are generated by Cisco
PGW 2200 Softswitch processes. You can also define thresholds which, if exceeded, could produce
alarms.
• Accounting management—Dumps generated CDRs to locally persistent files or to remote databases
through a standard or customized API.
The following types of external clients can access or manipulate data on the Cisco PGW 2200
Softswitch:
• Man-Machine Language (MML) terminal—Serves as a command-line interpreter. An operator can
issue commands to manipulate data for fault detection, measurements, or configuration. MML is
similar to TL/1, which enables low-level system experts (such as operations personnel) to perform
rapid system configuration or troubleshooting.
• SNMP-based terminal—Enables you to use SNMP to access network data. You can use the data to
manage system performance, to collect measurements, and to maintain security. The Cisco PGW
2200 Softswitch has a master agent (EMANATE from SNMP Research), which includes the
following subagents that provide SNMP access to the system:
– Operations—Custom subagent that provides access to fault data.
– Measurement—Custom subagent that provides access to measurement data.
– Critical application monitor—Standard CIAgent subagent that monitors the process manager
(procM) process.
– Host resources MIB—Standard CIAgent subagent that accesses data, such as the number of
processors, and memory usage in the Cisco PGW 2200 Softswitch.
– MIB-II—Standard CIAgent subagent that partially supports the MIB-II standard (RFC-1213).
– File system monitor—Standard CIAgent subagent that monitors thresholds for five file systems.
• TIBCO management system—Introduced in Release 9.5(2), the Cisco PGW 2200 Softswitch
TIBCO interface enables you to use a TIBCO management system to add, modify, delete, and
retrieve provisioning data on the Cisco Cisco PGW 2200 Softswitch. The Cisco PGW 2200
Softswitch supports TIBCO Version 6 daemons and libraries. When this interface is enabled, the
Cisco PGW 2200 Softswitch can communicate with one of two TIBCO daemons on your
management system:
– Rendezvous Daemon (RVD)—Used when the management system is in the same network as the
Cisco PGW 2200 Softswitch. The TIBCO adapter on the Cisco PGW 2200 Softswitch
automatically starts RVD on the management system unless either the RVD or Routing Daemon
(RVRD) is already running.
