Note The following parameters are not backed up and restored: node name, IP address, subnet mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.



Caution E10/100-4 cards lose traffic for approximately 90 seconds when an ONS 15327 database is restored. Traffic is lost during the period of spanning tree reconvergence. The carrier loss (CARLOSS) alarm appears and clears during this period.


Caution If you are restoring the database on multiple nodes, wait approximately one minute after the XTC reboot has completed on each node before proceeding to the next node.


Note If you want to revert to a previously loaded software version, refer to the platform-specific upgrade guide for instructions.



Step 1 Complete the "DLP-B60 Log into CTC" task at the node where you are restoring the database. If you are already logged in, continue with Step 2.

Step 2 Ensure that no ring or span (four-fiber only) switch events are present; for example, ring-switch east or west, and span-switch east or west. In network view, click the Conditions tab and click Retrieve to view a list of conditions.

Step 3 If switch events need to be cleared, in node view click the Maintenance > BLSR tabs and view the West Switch and East Switch columns.

a. If a switch event (not caused by a line failure) is present, choose CLEAR from the drop-down list and click Apply.

b. If a switch event caused by the Wait to Restore (WTR) condition is present, choose CLEAR from the drop-down list and click Apply.

Once a switch event is cleared, NO COMMAND appears in the column to indicate that the switch event is no longer in effect.

Step 4 In node view, click the Maintenance > Database tabs (Figure 14-1).

Caution Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinit tool chooses the first product-specific software package in the specified directory if you use the Search Path field instead of the Package and Database fields. You may accidentally copy an incorrect database if multiple databases are kept in the specified directory.


Caution Restoring a node to the factory configuration deletes all cross-connects on the node.


Caution Cisco recommends that you take care to save the node database to safe location if you will not be restoring the node using the database provided on the software CD.


Note The following parameters are not backed up and restored when you delete the database and restore the factory settings: node name, IP address, subnet mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits map to the new renamed node. Cisco recommends keeping a record of the old and new node names.



Step 1 If you need to install or replace one or more XTC cards, complete the"NTP-B217 Install the XTC Cards" procedure.

Step 2 If you are using Microsoft Windows, complete the "DLP-B244 Use the Reinitialization Tool to Clear the Database and Upload Software (Windows)" task.

Table 14-2 ONS 15327 Timing Report 

Item
Description
Options
Option Descriptions

Clock

Indicates the timing clock. The report section that follows applies to the timing clock indicated.

NE

The node timing clock.

BITS-1 Out

The BITS-1 Out timing clock.

BITS-2 Out

The BITS-2 Out timing clock.

Status

Indicates the status of the timing clock.

INIT_STATE

The timing reference has not been provisioned. For an NE reference, this status appears just before the first provisioning messages when the XTC is booting. Timing is provisioned to the internal clock of the node.

HOLDOVER_STATE

The clock was locked onto a valid timing reference for more than 140 seconds when a failure occurred. Holdover state timing is a computation based on timing during normal state combined with the node's internal clock. The node holds onto this frequency until the valid reference is restored. This status appears for NE references only.

FREERUN_STATE

The node is running off its internal clock without any modification except the calibrated value to bring timing to 0 PPM. Free-run state can occur when a Force switch to the Internal clock is initiated, all references fail without the 140 seconds of holdover data, or only Internal timing references are defined. This status appears for NE references only.

NO_SYNC_STATE

A synchronization timing reference is not defined. BITS-1 Out or BITS-2 Out default to this status until an OC-N card is defined as its reference on the Provisioning > Timing tab. This status appears for external references only.

NE_SYNCH_STATE

BITS-1 Out and BITS-2 Out use the same timing source as the NE. This appears when NE Reference is selected for BITS-1 Out and BITS-2 Out Reference List on the Provisioning > Timing tab.

NORMAL_STATE

The timing reference is locked onto one of its provisioned references. The reference cannot be Internal or No Sync state.

FAST_START_STATE

The node has switched references, but the reference is too far away to reach normal state within an acceptable amount of time. Fast Start is a fast acquisition mode to allow the node to quickly acquire the reference. After it achieves this goal, the node progresses to the normal state.

FAST_START_FAILED_STATE

A timing reference is too far away to reach in normal state. The fast start state could not acquire sufficient timing information within the allowable amount of time.

Status Changed At

Indicates the date and time of the last status change.

Switch Type

Indicates the type of switch.

AUTOMATIC

The timing switch was system-generated.

   

Manual

The timing switch was a user-initiated Manual switch.

Force

The timing switch was user-initiated Force switch.

Reference

Indicates the timing reference.

Three timing references (Ref-1, Ref-2, and Ref-3) are available on the Provisioning > Timing tab.

These options indicate the timing references that the system uses, and the order in which they are called. (For example, if Ref-1 becomes available, Ref-2 is called.)

Selected

Indicates whether the reference is selected.

Selected references are indicated with an X.

Facility

Indicates the timing facility provisioned for the reference on the Provisioning > Timing tab.

BITS-1

The timing facility is a BITS clock attached to the node's BITS-1 pins.

BITS-2

The timing facility is a BITS clock attached to the node's BITS-2 pins.

OC-N card with port #

If the node is set to line timing, the OC-N card and port provisioned as the timing reference.

Internal clock

The node is using its internal clock.

State

Indicates the timing reference state.

IS

The timing reference is in service.

OOS

The timing reference is out of service.

Condition

Indicates the timing reference state.

OKAY

The reference is valid to use as a timing reference.

OOB

Out of bounds; the reference is not valid and cannot be used as a timing reference, for example, a BITS clock is disconnected.

Condition Changed

Indicates the date and time of the last status change in MM/DD/YY HH:MM:SS format.

SSM

Indicates whether SSM is enabled for the timing reference.

Enabled

SSM is enabled.

Disabled

SSM is not enabled.

SSM Quality

Indicates the SSM timing quality.

8 to 10 SSM quality messages can appear.

For a list of SSM message sets, refer to the "Security" chapter and "Timing" chapters in the Cisco ONS 15327 Reference Manual.

Note To determine whether you have an active or standby XTC, position the cursor over the XTC card graphic to display the status.



Step 1 Ensure that the XTC you want to reset is in standby mode. On the XTC card, the ACT/STBY (Active/Standby) LED is amber when the XTC is in standby mode.

Step 2 When the XTC is in standby mode, unlatch both the top and bottom ejector levers on the XTC card.

Step 3 Physically pull the card at least partly out of the slot until the lighted LEDs turn off.

Step 4 Wait 30 seconds. Reinsert the card and close the ejector levers.


Note The XTC takes several minutes to reboot and displays the amber standby LED after rebooting. Refer to the "NTP-B217 Install the XTC Cards" procedure for more information about LED behavior during XTC reboot.


Stop. You have completed this procedure.


NTP-B270 Edit Network Element Defaults

Purpose

This procedure edits factory-configured network element (NE) defaults using the NE Defaults editor. The new defaults can either be applied only to the node on which they are edited or exported to a file and imported for use on other nodes.

Note For a list of card and node default settings, refer to the "Network Element Defaults" appendix in the Cisco ONS 15327 Reference Manual. To change card settings individually (that is, without changing the defaults), see Chapter 9 "Change Port Settings."To change node settings, see Chapter 10 "Change Node Settings."



Step 1 Complete the "DLP-B60 Log into CTC" task at the node where you want to edit NE defaults.

Step 2 Click the Provisioning > Defaults tabs.

Step 3 Under Defaults Selector, choose a card type (if editing card-level defaults), CTC (if editing CTC defaults), or NODE (if editing node-level defaults). Clicking on the node name (at the top of the Defaults Selector column) lists all available NE defaults in the Default Name column. To selectively display just the defaults for a given card type, for node-level, or for CTC-level, you can drill down the Defaults Selector menu structure.

Step 4 Locate a default you want to change under Default Name.

Step 5 Click in the Default Value column for the default property you are changing and either choose a value from the drop-down menu (when available), or type in the desired new value.


Note If you click Reset before you click Apply, all values will return to their original settings.


Step 6 Click Apply (click in the Default Name column to activate the Apply button if it is unavailable). You can modify multiple default values before applying the changes.

A pencil icon will appear next to any default value that will be changed as a result of editing the defaults file.

Step 7 If you are modifying node-level defaults, a dialog box appears telling you that applying defaults for node level attributes overrides current provisioning and asks if you want to continue. Click Yes.

If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.


Note Changes to most node defaults reprovision the node when you click Apply. Changes made to card settings using the Defaults Editor do not change the settings for cards that are already installed or slots that are preprovisioned for cards, but rather, change only cards that are installed or preprovisioned thereafter. To change settings for installed cards or pre-provisioned slots, see Chapter 9 "Change Port Settings."



Note Changing some NE defaults can cause CTC disconnection or a reboot of the node in order for the default to take effect. Before you change a default, view the Side Effects column of the Defaults editor (right-click a column header and select Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for that default.


Stop. You have completed this procedure.


NTP-B271 Import Network Element Defaults

Purpose

This procedure imports the NE defaults using the NE Defaults editor. The defaults can either be imported from the CTC software CD (factory defaults) or from a customized file exported and saved from a node.

Note For a list of card and node NE defaults, refer to the "Network Element Defaults" appendix in the Cisco ONS 15327 Reference Manual.



Step 1 Complete the "DLP-B60 Log into CTC" task at the node where you want to import NE defaults.

Step 2 Click the Provisioning > Defaults tabs.

Step 3 Click Import.

Step 4 Click Browse and browse to the file you are importing if the correct file name and location of the desired file do not appear in the Import Defaults from File dialog box.

Step 5 When the correct file name and location appear in the dialog box (the correct file name is 15327-defaults.txt if you are importing the factory defaults), click OK.

A pencil icon will appear next to any default value that will be changed as a result of importing the new defaults file.

Step 6 Click Apply.

Step 7 If the imported file fails to pass all edits, the problem field shows the first encountered problem default value that must be fixed. Change the problem default value and click Apply. Repeat until the imported file passes all edits successfully.

Step 8 If you are modifying node-level defaults, a dialog box appears telling you that applying defaults for node level attributes overrides current provisioning and asks if you want to continue. Click Yes.

If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.


Note Changes to most node defaults reprovision the node when you click Apply.

Note The defaults currently displayed are exported whether or not they have been applied to the current node.



Note The NE defaults can also be exported from the File > Export menu. These exported defaults are for reference only and cannot be imported.



Step 1 Complete the "DLP-B60 Log into CTC" task at the node where you want to export NE defaults.

Step 2 Click the Provisioning > Defaults tabs.

Step 3 Click Export.

Step 4 If the desired file to export to does not appear in the Export Defaults to File dialog box (or does not yet exist) click Browse and browse to the directory where you want to export the data; then either choose or type in (to create) the file to export to [the defaults will be exported as a text file delimited by equals (=) signs].

Step 5 Click OK.

Stop. You have completed this procedure.
