The Cisco ONS 15194 is a high-density, high-performance IP transport management platform that delivers enhanced scalability and manageability in dynamic packet transport (DPT) and packet over SONET (POS) environments. Key features follow:
For the complete product documentation refer to the Cisco ONS 15194 Installation and Configuration Guide.
The following sections describe basic node and ring configuration that can be done using the Cisco ONS 15194.
The basic configurable unit in the ONS 15194 is a node. A node reflects the characteristics of the external device that is connected to the ONS 15194 interface using fiber-optic cables. External devices are typically routers, but can also be other ONS 15194s or other SONET/SDH equipment such as ADMs. An example of a node is the A and B interfaces of an SRP line card on a router. Another example is a POS interface on a router.
You can either manually define nodes or let the ONS 15194 automatically detect them. After you define nodes, you need to interconnect them. The way in which this is done depends on the types of nodes used. The following nodes are supported by the ONS 15194:
Although a node describes the characteristics of an external device, a node can be logically defined before the device is actually connected to the ONS 15194 or even before the line card supporting the node is present on the ONS 15194. A detailed description of the various types of nodes is presented later in this chapter.
The rconf configuration mode is used for defining and connecting nodes. It contains a wide variety of commands that assist in configuring the ONS 15194 while causing minimal impact to existing traffic. The ONS 15194 automatically detects nodes, assists in forming valid connections, and aids in avoiding user errors. Two concepts are central to understanding the use of the rconf configuration mode: draft configurations and running configurations.
The running configuration pertains to both rconf configuration commands as well as other configuration commands. The draft configuration pertains only to rconf configuration commands.
All rconf commands, except for the apply command, modify only the draft configuration. After you prepare all the elements of the desired configuration in the draft configuration, you can copy it or apply it to the running configuration using the apply command. Because the results of multiple configuration commands are applied to the hardware at one time, minimal traffic disruption occurs. Following is a short description of the diverse options available in the rconf configuration mode. All commands discussed in this section are described in detail in the Cisco ONS 15194 Installation and Configuration Guide, Chapter 5, "Command Line Interface Reference."
In rconf configuration mode, the user has two options to begin defining a new draft configuration:
Use five switch cards and two controller cards in the ONS 15194 so that the redundancy features in the software work correctly. Although not recommended, the ONS 15194 will continue to operate with four switch cards and one controller card.
The ONS 15194 software is only supported by the ONS 15194. You cannot run a ONS 15194 software image on the ONS 15190.
In software Release 1.1, use the show version EXEC command to display the currently running release of the software. The following example illustrates sample output from the show version command. In this example, the software release is 1.0, and the software build is 1.0.24.

To upgrade the software to a new release, do the following:
Step 1 Enter privileged EXEC command mode and use the copy command to copy the software image to the ONS 15194 Flash memory from one of the PCMCIA ATA Flash memory disks or a TFTP or FTP server.
 |
Note You cannot boot the ONS 15194 from an image file located on a PCMCIA disk. The file must be copied to the ONS 15194 Flash memory. |
Step 2 Use the boot system global configuration command to specify that the new software image be used to boot the system.
Step 3 Use the write privileged EXEC command to save the boot system configuration changes to the Flash memory.
Step 4 Use the show bootvar EXEC command to verify that the boot variable has been changed to be the new software image.
Step 5 Use the reload privileged EXEC command to boot the controllers with the new software image. It will take a few minutes for both controllers to be reloaded.
Step 6 When the system reloads, use the show version command to verify that the new software image is running.
The following example illustrates the software upgrade procedure, where the software image file name is ons15194-12.bin.
ons15194# copy tftp://192.168.113.200/ons15194-12.bin flash:

The main addition to Release 1.1 is the data statistics recording and display capability. In addition, a number of new commands were added to the command line interface.
New software features in Release 1.2 are described following:
Release 1.2 supports access via SSH or Telnet. Both DES and 3DES encrytion methods are supported for SSH. Use the show ssh EXEC command to display all active SSH sessions. Use the show users EXEC command to display all active sessions, including SSH.
New software features in Release 1.1 are described following:
The following new functionality and improvements were made in Release 1.1:
To display the data statistics of traffic flowing through the ONS 15194, use the following commands:
The rate displayed in the show nodes data command is the net rate for the node, meaning that if more data is transmitted than received, the rate will be a positive value. Use the rate value to determine if data is being passed through the node, data is originating in the node, or data is exiting via the node. If the same amount of data is transmitted and received, the rate value should be equal to zero.
For syntax information for the data statistics commands, refer to the Cisco ONS 15194 Installation and Configuration Guide.
The hw-module interface tx-pathtrace command was added to the command line interface. This command temporarily changes the path trace message transmitted by an interface. This command is primarily intended for testing purposes. The transmitted path trace message reverts to the default when any change occurs in the ONS 15194 configuration, including use of the apply rconf configuration command or when the physical status of the node or connection changes.
Use the show interfaces tx-pathtrace command to view the current path trace message transmitted by an interface.
Refer to the Cisco ONS 15194 Installation and Configuration Guide for the syntax of these commands.
To display the logging file of the standby controller, use the show logging remote command. Refer to the Cisco ONS 15194 Installation and Configuration Guide for the syntax of this command.
The installation of the ONS 15194 is discussed in the document Cisco ONS 15194 Installation Note.
The EIPS functionality is disabled by default. When it is enabled, it applies to both A/B SRP rings and SRP-inner and SRP-outer rings.
If you are using SRP-inner and SRP-outer rings, enable the EIPS functionality using the eips enable rconf configuration command on both ONS 15194s. If the EIPS functionality is not enabled, and there is a failure in one of the ONS 15194s, a subsequent router failure will cause the ring to stop functioning.
The ONS 15194 has a Flash memory file system. While the file system is designed to be an open file system that enables flexible manipulation of directories and files, the following guidelines should be followed:
Each controller card has one Ethernet interface. When the software is running, only the interface of the active controller card is operational. Because of this, only one IP address needs to be configured for the ONS 15194, which is always used by the currently active controller card.
You should connect both Ethernet interfaces to a hub or switch. If two controller cards are installed in the ONS 15194, but only one is connected to a hub or switch, you will loose all IP connectivity if the controller card is reloaded.
If IP connectivity is necessary and you must reload the controller card, you should verify that the standby controller is connected to the network via the Ethernet interface. Either visually verify the presence of the Ethernet cable and the link LED or use the following command remotely on the standby controller:
show hw-module slot {C1 | C2}
Verify that the link status field is up as illustrated in the following example:
ons15194# show hw-module slot C2
Controller Card 2 (Other controller):
Subtype: TurboStar Controller
State: Operational
Active state: Active
Link status: Up
Catalog number: TS-controller
Serial number: 000002c
Board version: 73-7180-01
