Configuring OAP
Overview
The Open Application Platform (OAP) is an open application protocol that is based on the Open
Application Architecture (OAA). OAA allows products from different vendors to operate together to
meet service requirements.
Figure 1 OAA diagram
As shown in Figure 1, OAA includes the following components:
•
Routing/switching component—Provides routing and switching services. This component is
the control center of the entire architecture.
•
Standalone service component—Provides services to meet specific requirements.
•
Interfacing component—Connects the standalone service component to the
routing/switching component.
OAP is used for communication and cooperation between the routing/switching component and the
standalone service component. The routing/switching component is the OAP manager, and the
standalone service component is the OAP client.
The device can act as the OAP manager. The OAP manager software is integrated in the Comware
system.
The OAP client can be a third-party product or an OAP module. OAP modules provide value-added
services, such as security and wireless control. OAP modules have their own CPUs and storage
media. The OAP client software is integrated in the operating system of the OAP module as a
function.
You can install an OAP module in the device. For example, you can install an IDS/IPS OAP module
in the device to provide intrusion detection and protection services.
OAP functions
OAP provides the following functions:
•
OAP clients register with and deregister from the OAP manager.
•
The OAP manager assigns IDs to OAP clients to uniquely identify the clients.
•
The OAP manager and an OAP client exchange information to, for example, monitor each other
and synchronize the clock.
From the OAP manager, you can perform the following tasks:
•
Restart OAP clients.
•
Shut down OAP clients.
•
Display OAP client information.
An OAP manager can manage up to 255 OAP clients.

OAP manager timers
The OAP manager uses the following timers:
•
Clock synchronization timer—Regularly triggers the OAP manager to send clock and time
zone synchronization notifications to OAP clients. This mechanism keeps the clients' clocks
synchronized with the manager's clock.
•
Client monitoring timer—Regularly triggers the OAP manager to send client monitoring
packets to OAP clients.

Configuring the OAP module
The Open Application Architecture provides an open interface for third-party vendors to develop and
integrate value-added applications into H3C products. The hardware platforms for these applications
can be devices or modules. H3C has developed series of application-specific modules called Open
Application Platform (OAP) modules.
OAP modules have their own operating systems. You can log in to the operating system of an OAP
module to install features. For example, you can install security features and voice features on the
OAP module operating system to provide security and voice services for users.
OAP modules exchange data, status information, and control information with hosting devices
through internal interfaces.

Internal interfaces for OAP modules
An OAPmodule integrates a front card and a rear card. The front card provides value-added security
services, such as firewall, intrusion prevention, and application control. The rear card is responsible
for data exchange between the front card and the switch. The rear card communicates with the front
card through the internal interface, as shown in Figure 1.

Logging in to an OAP module
Logging in through the console port on the OAP module
1. Connect one end of the console cable to the serial port of the configuration terminal (for
example, a PC).
2. Connect the other end of the console cable to the console port of the OAP module.
3. Start the PC and run a terminal emulation program, such as HyperTerminal.
4. Select the COM connection mode and set the terminal parameters as follows:
Bits per second—9600.
Data bits—8.
Parity check mode—None.
Stop bits—1.
Flow control—None.
5. Follow the OAP module user guide to log in to the operating system of the OAP module through
the terminal emulation program.
Logging in through the management Ethernet port on the
OAP module by using SSH
1. Connect the management Ethernet port of the OAP module to the network by using a network
cable.
2. Log in to the OAP module through the console port and enable the SSH server function on the
OAP module.
3. Assign an IP address to the management Ethernet port of the OAP module. Make sure the
management Ethernet port and the SSH client (an H3C device or a PC with SSH client software)
can reach each other.
4. From the SSH client, establish an SSH connection to the IP address of the management
Ethernet port on the OAP module.
After the SSH connection is successfully established, you are logged in to the operating system of
the OAP module.

Logging in through the internal Ethernet interface on the OAP
module by using SSH
When installed in the expansion slot of a device, an OAP module exchanges information with the
device through two internal interfaces: one serial port and one fast Ethernet interface. The fast
Ethernet interface is used for this login method.
To log in to the operating system of an OAP module through the internal Ethernet interface:
1. Connect the SSH client (for example, a PC) to the Ethernet port of the device by using a
network cable.
2. Log in to the OAP module through the console port and enable the SSH server function on the
OAP module.
3. Assign an IP address to the internal Ethernet interface on the OAP module. Make sure the PC
and the fast Ethernet interface on the OAP module can reach each other.
4. From the SSH client, establish an SSH connection to the IP address of the fast Ethernet
interface.
After the SSH connection is successfully established, you are logged in to the operating system of
the OAP module.
Logging in to the OAP module from the CLI of the device
IMPORTANT:
The following
modules do not support this login method:
•
LSU1IPSBEA0.
•LSQM1ACGDSC0.
From the CLI of the device, you can log in to the CLI of the OAP module. To return to the CLI of the
device, press Ctrl+K.
Perform the following task in user view on the default MDC:
Task
Command
Log in to the CLI of the OAP module from the
device.
In standalone mode:
oap connect slot slot-number
In IRF mode:
oap connect chassis chassis-number slot slot-number
Resetting OAP modules
CAUTION:
Resetting an OAP module might cause a service outage.

4
IMPORTANT:
To a
void service data loss, close the operating system of an OAP module before resetting the
module.
The following
modules do not support this operation:
•
LSUM1WCMX20RT.
•
LSUM1WCMX40RT.
•
LSU1IPSBEA0.
•LSU1WCME0.
You can reset an OAP module to restore it to normal operation in the following situations:
•
The OAP module fails.
•
The OAP module is not operating correctly. For example, the OAP module does not respond to
your operation.
Pressing the reset button of the OAP module has the same effect. The device can still identify and
control the OAP module after the module starts up again.
Perform the following task in user view:
Task
Command
Reset the OAP module.
In standalone mode:
oap reboot slot slot-number
In IRF mode:
oap reboot chassis chassis-number slot slot-number
