This document describes all additions or changes to running the ONS 15190 IP Transport Concentrator with Software Release 2.5. The Cisco ONS 15190 was previously known as the PentaCom RingStar8000.
Release 2.5 for the ONS 15190 is compatible with all existing ONS 15190 hardware platforms.
Execute the command system show info to display the version of the software that is currently running.
admin> system show info System uptime: 0:08:02.363 Name: ONS 15190 Description: Lab at Cisco Systems Location: Contact: Running image: Release: 1.0.23 Created on: Wed Jan 19 21:14:46 2000 Created by: Cisco Systems Length: 2282376 Signature: 0xEF2BE4F6 Software version: Build 23 Software built on: Jan 19 2000, 21:13:45 Bootstrap version: 3.0 Stored image: Release: 1.0.23 Created on: Tue Feb 01 01:21:56 2000 Created by: Cisco Systems Length: 2290824 Signature: 0x4E034E21
The running image release should be the same as the stored image release (in this example, version 1.0.23).
Instructions for upgrading to Release 2.5 are provided in the "Installation Notes" section.
Following is a list of the new hardware and software features supported by the Cisco ONS 15190 IP Transport Concentrator:
The following new hardware features are supported by Release 2.5 for the Cisco ONS 15190:
Software Release 2.5 supports the use of four-port OC-12c/STM-4 line cards (OC12/STM4-MM-SR-4, OC12/STM4-SM-IR-4, OC12/STM4-SM-LR-4, OC12/STM4-SM-XR-4) in the ONS 15190. Functionally the four-port card is identical to the two-port card, with the addition of a Tx/Rx port pair.
On LPM (laser power monitor) equipped four-port OC-12c/STM-4 line cards, you can display a laser power reading for the level of the laser as it enters the line card and the level of the laser as it is transmitted out. The input power is read from the hardware and has a resolution of 1.0 dBm. The output power is as read in the BOL (beginning of life) and has a resolution of 1.0 dBm.
To display these power measurements, execute the command port { all | port } show laser. Following is an example of the output from this command:
admin> port all show laser Port Type Output Power Input Power ----- ----- ------------ ----------------- L3.1 OC12 Laser ON Monitor not supported for port L3.2 OC12 Laser ON Monitor not supported for port L4.1 OC12 -13.2 No Rx signal (Link Down) L4.2 OC12 -11.0 -24.0 L4.3 OC12 -12.4 higher than -18.0 L4.4 OC12 -12.0 lower than -32.0
If the port does not support the power laser monitor feature, this message is displayed for the port: Monitor not supported for port.
The following new software features are available in release 2.5:
The autotracker option allows you to automatically track a fiber pair even if it is moved from one port to another. The autotracker is by default disabled. When enabled and nodes are removed from or connected to the system, traps are sent to the control panel to indicate the changes. To enable the autotracker option, use the following command:
The trace-mode option allows you to set the path trace message of the ONS 15190 to be transparent for nodes of a specific type. For example, if node A is connected to node B via the ONS 15190, in transparent mode, the path trace message transmitted by B will be that received by A and not that of the ONS 15190. In normal mode, the ONS 15190 transmits its own path trace message to each connected node. By default, SRP and raw nodes are set to normal trace-mode and pos (APS) and sniff nodes are set to transparent trace-mode.
To enable or disable transparent path trace, use this command:
If you are upgrading from a release of the software below Release 2.0, follow the upgrade procedure in the section "Upgrading to Release 2.5 from Release 1.x". If you are upgrading from Release 2.0 or higher, follow the upgrade procedure in the section "Upgrading from Release 2.x".
 |
Note Upgrading to Release 2.5 will discard all sniff and raw connections and convert all unidirectional APS nodes to bidirectional. |
|
Note Downtime due to the software upgrade will be approximately 1 minute due to an update in the firmware. |
|
Note Due to changes in the database made in newer releases, it is not possible, following an upgrade, to revert to earlier versions of the system configuration. For this reason, you are advised to save the current configuration on your system before upgrading. Then if you experience a problem with the new release, you will be able to revert to the previous software revision and reload the old configuration. To save the configuration, execute the command tftp put ip-address filename conf, where ip-address is the IP address of the TFTP server where you are saving the configuration file and filename is the filename of the configuration file. |
To upgrade your ONS 15190 to Release 2.5 from any release before Release 2.0, perform the following procedure.
Step 2 Download the new software image file into the ONS 15190.
You need the TFTP server IP address where the file is located, as well as the name of the file. For example:
admin> tftp get 192.168.10.27 ver25 image Retrieving 192.168.10.27:ver1028... 2.18MB Done. Release : 2.5 Created by: Cisco Systems Created on: Tue Feb 01 01:21:56 2000 Are you sure? y Storing image ...100%. Validating image Done. Updating image information (might take a while) Done. Synchronizing image... waiting for standby controller to save image information... .........image synchronized OK done
In this example, the TFTP server IP address is 192.168.10.27, and the remote file name of the software update is ver25. When prompted with the version to be downloaded, enter y to continue with the download. When the download is complete, the file is stored within the Flash memory of both controller cards of the ONS 15190 unit, but is not the currently running version of the software.
Step 3 To run the newer version of the software, you must perform a system reset via the management software or physically.
admin> sys reset Controller will be reset. Are you sure? y bye User Name: Password: admin>
When the system is reset, communication will be lost to the controller. If you are connected via RS-232, notification of the lost communication appears on the screen; if you are connected via telnet, the connection will just stop functioning. You will need to log in to the system again.
When the system reboots, the now active controller (which was previously the standby controller) will still be running the old software version. However, the standby controller will be running the new software version. If you execute the command system show info, you will see that the old software version is currently running.
admin> system show info System uptime: 0:08:02.363 Name: ONS 15190 Description: Lab at Cisco Systems Location: Contact: Running image: Release: 1.0.23 Created on: Wed Jan 19 21:14:46 2000 Created by: Cisco Systems Length: 2282376 Signature: 0xEF2BE4F6 Software version: Build 23 Software built on: Jan 19 2000, 21:13:45 Bootstrap version: 3.0 Stored image: Release: 2.5 Created on: Tue Feb 01 01:21:56 2000 Created by: Cisco Systems Length: 2290824 Signature: 0x4E034E21
Note that in this example the stored release is version 2.5, but the current running software release is only 1.0.23.
Step 4 To complete the procedure so that the new version will be running on the active controller card, you must reset the system once again by executing the command sys reset. This will transfer control back to the original active controller which is already running the new version. The standby controller will now be reset to the new version as well. Once again, communication to the controller will be lost.
admin> sys reset Controller will be reset. Are you sure? y bye Active controller has been changed please re login User Name: Password: admin>
Step 5 Log back into the system and verify that the new version is running with the command sys show info. In this example, the running release is the version that was downloaded 2.5.
admin> system show info System uptime: 1:39:52.399 System time: THU MAY 18 17:30:58 2000 Name: ONS 15190 Description: Lab at Cisco Systems Location: Contact: Running image: Release: 2.5 Created on: Wed Jan 19 21:14:46 2000 Created by: Cisco Systems Length: 3053739 Signature: 0x1E9BA6E0 Software version: 2.5.11 Software created on:May 3 2000, 20:09:01 Bootstrap version: 3.0
The software download procedure is now successfully completed.
In order to update your ONS 15190 with a new release of the software after Release 2.0 or higher has already be installed, perform the following:
admin> tftp get 192.168.10.185 ver25 image Retrieving 192.168.10.185:ver2.5... 2.91MB Done. Release : 2.5 Created by: Cisco Systems Created on: Mon May 01 20:55:40 2000 Are you sure? y Storing image ...100%. Updating image information (might take a while) Done. ....synchronizing Image OK
In this example, the TFTP server IP address is 192.168.10.185, and the remote file name of the software update is ver25. When prompted with the version to be saved, y to continue with the process. After the file is downloaded, it is stored within the Flash memory of both controller cards ONS 15190 unit. A reset is performed automatically to the standby controller card (for example, C2) such that the new software version will be up and running on the standby controller, but not on the active controller (for example, C1).
Step 2 When prompted to reset the active controller (C1) in order to begin running the new software version, type y to continue. Control will be transferred to the previous standby controller (C2) that is already running the new software and C1 will be reset with the new software as well.
Changes will take affect only after controller reset Do you want to reset now? y resetting...
When the system is reset, communication will be lost to the controller. If you are connected via RS-232C, notification of the lost communication appears on the screen; if you are connected via telnet, the connection will just stop functioning. You will need to log in to the system again.
The system will now be running the new software version. If you perform the command system show info, you will see that the new software version is currently running.
admin> system show info System uptime: 0:26:32.053 System time: 0:26:32.055 Name: Description: Location: Contact: Running image: Release: 2.5 Created on: Mon May 01 20:55:40 2000 Created by: Cisco Systems Length: 3053611 Signature: 0xC55D7EFE Software version: 2.5.11 Software created on: May 1 2000, 20:48:11 Bootstrap version: 3.0
The software download procedure is now successfully completed.
All features specified in this document are supported in Release 2.5.
If you must revert to a previous version of the software, do the following:
admin> tftp get 192.168.10.27 ver20 image
In this example, the TFTP server IP address is 192.168.10.27 and the remote file name of the software update is ver20. When prompted with the version to be downloaded enter y to continue with the download. You must following the instructions for installing the particular software version that you are downloading.
Step 2 When the image is downloaded and running on your system, you must either download a previously saved version of the configuration file or execute the command system set factory default. The factory default will provide a black configuration for which you to begin defining your own configuration definitions. In order to download a previously saved version of the configuration file, execute the command: tftp get ip fname conf, where ip is the IP address where you have saved the configuration file and fname is the name of the file.
Release 2.5 only supports the connection of one sniff node at a time. All previously defined sniff connections will be disconnected when Release 2.5 is installed.
Release 2.5 only supports bidirectional APS nodes. Any previously defined unidirectional nodes will be converted to bidirectional mode when Release 2.5 is installed.
If fiber loops are present on the system, the path trace mode must be set to normal in order for features such as autotracker, autoconnect, and autodetect to function correctly.
When using OC-48c/STM-16 cards and traffic is comprised of minimally-sized packets (64 bytes), throughput may drop to 98%. Specifically, in the event of a burst of 2000 minimally-sized packets, about 2 packets may be dropped. Since such scenarios are very unlikely in real networks, this limitation is not expected to cause any impact on throughput.
When a switch card is extracted or reset, a small (<20 mSec) traffic loss may occur.
In the case of a PEM failure, no traps are generated. All CLI commands and indications operate properly and will indicate a faulty PEM, if this condition exists. A red LED on the PEM card indicates a faulty PEM.
The standby controller is recognized as operational and fully redundant whenever the card is inserted and powered up. However, in the rare event that the image in the controller Flash memory is not operational, the standby controller is not actually operating. The two instances that this may happen are as follows:
In such an event, the FAIL LED on the controller will be lit. If you are at a remote location and suspect a problem with the standby controller, you can determine whether it is in fact operational by performing an internal ping on the backplane to both controllers (10.1.1.0 & 10.1.1.1). If a response is received from both, then they are operational and the system is redundant.
Sniff nodes don't automatically receive the characteristics of the sniffed node, that is, they must be manually configured to be compatible with the sniffed node.
This section details any caveats in using the ONS 15190 as of Release 2.5.
The active controller card must be reset before beginning the software download. Use the command: system reset. This may result in a subsequent reset of the standby controller as well. When the controller(s) have completed the reset, follow the standard upgrade procedure as described in the manual or release notes.
|
Note Resetting the controllers does not effect the flow of traffic. |
In order to revert to a older software release, follow the upgrade procedure to download the proper software release. When the update is completed, set the factory defaults with the command system set factory default. At this point, the system must be re-configured manually or a previously saved configuration file for the older version may be retrieved using the command: tftp get IP fname conf, where fname is the name of the configuration file and IP is the IP address of the TFTP server where it was saved.
