Node Setup


This chapter explains how to set up a Cisco ONS 15454 node using the Cisco Transport Controller (CTC). Topics include:

Setting up general node information

Preparing the ONS 15454 to connect to networks

Changing the node IP address, default router, and subnet mask using the LCD

Creating, editing, and deleting ONS 15454 users and assigning user security levels

Setting the node timing references

Creating card protection groups

Viewing node inventory

Viewing CTC software versions

Lastly, the chapter includes a node checklist to help you keep track of the procedures you have performed. See Chapter 2, "Software Installation" for general CTC information.

3.1 Before You Begin

Before you begin node setup, review the following checklist to ensure you have the perquisite information. Basic node information that you will provide need includes node name, contact, location, date, and time. If the ONS 15454 will be connected to a network, you will need:

The IP address and subnet mask to assign to the node and

The IP address of the default router.

If Dynamic Host Configuration Protocol is used, you will need the IP address of the DHCP server.

If you are responsible for setting up IP networking for the ONS 15454 network, see Chapter 4, "IP Networking" for more information.

To create card protection groups, you will need to know:

The card protection scheme that will be used and what cards will be included in it.

The SONET protection topology that will be used for the node.


Note You must be able to log into the node to complete node provisioning. If you cannot log into the node, see "Connecting PCs to the ONS 15454" section on page 2-5.


3.2 Setting Up Basic Node Information

Setting basic information for each Cisco ONS 15454 node is one of the first provisioning tasks you perform. This information includes node name, location, contact, and timing. Completing the information for each node facilitates ONS 15454 management, particularly when the node is connected to a large ONS 15454 network.

Procedure: Add the Node Name, Contact, Location, Date, and Time


Step 1 Log into the ONS 15454 node. The CTC node view is displayed.

Step 2 Click the Provisioning > General tabs.

Step 3 Enter the following:

Node Name—Type a name for the node. For TL1 compliance, names must begin with an alpha character and have no more than 20 alphanumeric characters.

Contact—Type the name of the node contact person and the phone number (optional).

Location—Type the node location (optional) (such as a city name or specific office location).

Latitude—Enter the node latitude: N (North) or S (South), degrees, and minutes.

Longitude—Enter the node longitude: E (East) or W (West), degrees, and minutes.

CTC uses the latitude and longitude to position node icons on the network view map. (You can also position nodes manually.) To convert a coordinate in degrees to degrees and minutes, multiply the number after the decimal by 60. For example, the latitude 38.250739 converts to 38 degrees, 15 minutes (.250739 x 60 = 15.0443, rounded to the nearest whole number).

Use SNTP Server—When checked, CTC uses a Simple Network Time Protocol (SNTP) server to set the date and time of the node. Using an SNTP server ensures that all ONS 15454 network nodes use the same date and time reference. The server synchronizes the node's time after power outages or software upgrades. If you check Use SNTP Server, type the server's IP address in the next field. If you do not use an SNTP server, complete the Date, Time, and Time Zone fields. The ONS 15454 will use these fields for alarm dates and times. (CTC displays all alarms in the login node's time zone for cross network consistency.)

Date—Type the current date.

Time—Type the current time.

Time Zone—Select the time zone.

Step 4 Click Apply.


3.3 Setting Up Network Information

ONS 15454s almost always operate in network environments. Before you connect an ONS 15454 to other ONS 15454s or to a LAN, you must change the default IP address that is shipped with each ONS 15454 (192.1.0.2). IP addresses are unique identifiers for devices—called hosts—that connect to TCP/IP networks. Every IP address includes a network number, which is assigned to an organization, and a host (device) number, which the organization's LAN administrator assigns to an individual network device. Subnetting enables LAN administrators to create subnetworks that are transparent to the Internet. Within networks, ONS 15454s often exist as subnetworks, which are created by adding a subnet mask to the ONS 15454 IP address.

The following procedure tells you how to set up the essential ONS 15454 networking information. Additional ONS 15454 networking information and procedures, including IP addressing examples, static route scenarios and Open Shortest Path First (OSPF) protocol options are provided in Chapter 3, "IP Networking."

Procedure: Set Up Network Information


Step 1 From the CTC node view, click the Provisioning > Network tabs ( Figure 3-1).

Step 2 Complete the following:

IP Address—Type the IP address assigned to the ONS 15454 node.

Prevent LCD IP Config—If checked, prevents the ONS 15454 IP address from being changed using the LCD. See the "Change IP Address, Default Router, and Network Mask Using the LCD" procedure.

Default Router—If the ONS 15454 must communicate with a device on a network to which the ONS 15454 is not connected, the ONS 15454 forwards the packets to the default router. Type the IP address of the router in this field. If the ONS 15454 is not connected to a LAN, leave the field blank.

Subnet Mask Length—If the ONS 15454 is part of a subnet, type the subnet mask length (decimal number representing the subnet mask length in bits) or click the arrows to adjust the subnet mask length. The subnet mask length is the same for all ONS 15454s in the same subnet.


Note The MAC Address is read only. It displays the ONS 15454 address as it is identified on the IEEE 802 Media Access Control (MAC) layer.


Forward DHCP Request ToWhen checked, forwards Dynamic Host Configuration Protocol requests to the IP address entered in the Request To field. DHCP is a TCP/IP protocol that enables CTC computers to get temporary IP addresses from a server. If you enable DHCP, CTC computers that are directly connected to an ONS 15454 node can obtain temporary IP addresses from the DHCP server.

TCC CORBA (IIOP) Listener PortSets a listener port to allow communication with the ONS 15454 through firewalls. See the "Accessing ONS 15454s Behind Firewalls" section on page 2-12 for more information.

Figure 3-1 Setting up general network information

Step 3 Click Apply.

Step 4 Click Yes on the confirmation dialog box.

Both ONS 15454 TCC+ cards will reboot, one at a time.


Procedure: Change IP Address, Default Router, and Network Mask Using the LCD

You can change the ONS 15454 IP address, subnet mask, and default router address using the Slot, Status, and Port buttons on the front panel LCD.


Note The LCD reverts to normal display mode after 5 seconds of button inactivity.



Step 1 On the ONS 15454 front panel, repeatedly press the Slot button until Node appears on the LCD.

Step 2 Repeatedly press the Port button until the following displays:

To change the node IP address, Status=IpAddress ( Figure 3-2)

To change the node network mask, Status=Net Mask

To change the default router IP address, Status=Default Rtr

Figure 3-2 Selecting the IP address option

Step 3 Press the Status button to display the node IP address ( Figure 3-3), the node subnet mask length, or default router IP address.

Figure 3-3 Changing the IP address

Step 4 Push the Slot button to move to the IP address or subnet mask digit you need to change. The selected digit flashes.

Step 5 Press the Port button to cycle the IP address or subnet mask digit to the correct digit.

Step 6 When the change is complete, press the Status button to return to the Node menu.

Step 7 Repeatedly press the Port button until the Save Configuration option appears ( Figure 3-4).

Figure 3-4 Selecting the Save Configuration option

Step 8 Press the Status button to select the Save Configuration option.

A Save and REBOOT message appears ( Figure 3-5).

Figure 3-5 Saving and rebooting the TCC+

Step 9 Press the Slot button to save the new IP address configuration. (Or press Port to cancel the configuration.)

Saving the new configuration causes the TCC+ cards to reboot. During the reboot, a "Saving Changes - TCC Reset" message displays on the LCD. The LCD returns to the normal alternating display after the TCC+ reboot is complete.


3.4 Creating Users and Setting Security

The CISCO15 user provided with each ONS 15454 can be used to set up other ONS 15454 users. You can add up to 500 users to one ONS 15454. Each ONS 15454 user can be assigned one of the following security levels:

Retrieve users can retrieve and view CTC information but cannot set or modify parameters.

Maintenance users can access only the ONS 15454 maintenance options.

Provisioning users can access provisioning and maintenance options.

Superusers can perform all of the functions of the other security levels as well as set names, passwords, and security levels for other users.

Table 3-1 shows the actions that each user can perform in node view.

You can perform ONS 15454 user management tasks from network or node view. In network view, you can add, edit, or delete users from multiple nodes at one time. If you perform user management tasks in node view, you can only add, edit, or delete users from that node.


Note You must add the same user name and password to each node the user will access.


Procedure: Create New Users


Step 1 In network view, select the Provisioning > Security tabs.

Step 2 On the Security pane, click Create.

Step 3 In the Create User dialog box, enter the following:

Name—Type the user name.

Password—Type the user password. The password must be a minimum of six and a maximum of ten alphanumeric (a-z, A-Z, 0-9) and special characters (+, #, %), where at least two characters are non-alphabetic and at least one character is a special character.

Confirm Password—Type the password again to confirm it.

Security Level—Select the user's security level.

Step 4 Under "Select applicable nodes," deselect any nodes where you do not want to add the user (all network nodes are selected by default).

Step 5 Click OK.


Procedure: Edit a User


Step 1 In network view, select the Provisioning > Security tabs.

Step 2 Click Change.

Step 3 On the Change User dialog box, edit the user information: name, password, password confirmation, and/or security level. (A Superuser does not need to enter an old password. Other users must enter their old password when changing their own passwords.)


Note You cannot change the CISCO15 user name.


Step 4 If you do not want the user changes to apply to all network nodes, deselect the unchanged nodes in the Change Users dialog box.

Step 5 Click OK.

Changed user permissions and access levels do not take effect until the user logs out of CTC and logs back in.


Procedure: Delete a User


Step 1 In network view, select the Provisioning > Security tabs.

Step 2 Click Delete.

Step 3 On the Delete User dialog box, enter the name of the user you want to delete.

Step 4 If you do not want to delete the user from all network nodes, deselect the nodes.

Step 5 Click OK and click Apply.


3.5 Creating Protection Groups

The ONS 15454 provides several card protection methods. When you set up protection for ONS 15454 cards, you must choose between maximum protection and maximum slot availability. The highest protection reduces the number of available card slots; the highest slot availability reduces the protection. Table 3-3 shows the protection types that can be set up for ONS 15454 cards.

Table 3-3 Protection Types 

Type
Cards
Description

1:1

DS-1

DS-3

EC-1-12

DS3XM-6

Pairs one working card with one protect card. Install the protect card in an odd-numbered slot and the working card in an even-numbered slot next to the protect slot towards the center, for example: protect in Slot 1, working in Slot 2; protect in Slot 3, working in Slot 4; protect in Slot 15, working in Slot 14.

1:N

DS-1

DS-3

Assigns one protect card for several working cards. The maximum is 1:5. Protect cards (DS1N-14, DS3N-12) must be installed in Slots 3 or 15 and the cards they protect must be on the same side of the shelf. Protect cards must match the cards they protect. For example, a DS1N-14 can only protect DS1-14 or DS1N-14 cards. If a failure clears, traffic reverts to the working card after the reversion time has elapsed.

1+1

Any optical

Pairs a working optical port with a protect optical port. Protect ports must match the working ports. For example, Port 1 of an OC-3 card can only be protected by Port 1 of another OC-3 card. Cards do not need to be in adjoining slots.

Unprotected

Any

Unprotected cards can cause signal loss if a card fails or incurs a signal error. However, because no card slots are reserved for protection, unprotected schemes maximize the service available for use on the ONS 15454. Unprotected is the default protection type.


Procedure: Create Protection Groups


Step 1 From the CTC node view, click the Provisioning > Protection tabs.

Step 2 Under Protection Groups, click Create.

Step 3 In the Create Protection Group dialog box, enter the following:

Name—Type a name for the protection group. The name can have up to 32 alpha-numeric characters.

Type—Choose the protection type: 1:1, 1:N, or 1+1. The protection selected determines the cards that are available to serve as protect and working cards. For example, if you choose 1:N protection, only DS-1N and DS-3N cards are displayed.

Protect Card or Port—Choose the protect card (if using 1:1 or 1:N) or protect port (if using 1+1) from the list.

Based on these selections, a list of available working cards or ports is displayed under Available Cards or Available Ports. Figure 3-6 shows a 1+1 protection group.

Figure 3-6 Creating a 1+1 protection group

Step 4 From the Available Cards or Available Ports list, choose the card or port that you want to be the working card or port (the card(s) or port(s) that will be protected by the card or port selected in Protect Cards or Protect Ports). Click the top arrow button to move each card/port to the Working Cards or Working Ports list.

Step 5 Complete the remaining fields:

Bidirectional switching—(optical cards only) click if you want both the transmit and the receive channels to switch if a failure occurs to one.

Revertive—if checked, the ONS 15454 reverts traffic to the working card or port after failure conditions stay corrected for the amount of time entered in Reversion Time.

Reversion time—if Revertive is checked, enter the amount of time following failure condition correction that the ONS 15454 should switch back to the working card or port.

Step 6 Click OK.


Note To convert protection groups, see the "Converting DS-1 and DS-3 Cards From 1:1 to 1:N Protection" section on page 7-30.



Card protection does not take effect until you enable the ports on all the cards in the protection group. Because ports must be enabled before the cards carry traffic, you can enable the ports immediately after provisioning card protection, or wait until you are ready to send traffic on the cards.


Caution Before running traffic on a card within a protection group, enable the ports of all protection group cards.

Procedure: Enable Ports


Step 1 Log into the node in CTC and display the card you want to enable in card view.

Step 2 Click the Provisioning > Line tabs.

Step 3 Change the port status to In Service.

Step 4 Click Apply.


Procedure: Edit Protection Groups


Step 1 From the CTC node view, click the Provisioning > Protection tabs ( Figure 3-7).

Figure 3-7 Editing protection groups

Step 2 In the Protection Groups section, choose a protection group.

Step 3 In the Selected Group section, edit the fields as appropriate. (For field descriptions, see the "Create Protection Groups" procedure.)

Step 4 Click Apply.


Procedure: Delete Protection Groups


Step 1 From the CTC node view, click the Maintenance > Protection tabs.

Step 2 Verify that working traffic is not running on the protect card:

a. In the Protection Groups section, choose the group you want to delete.

b. In the Selected Group section, verify that the protect card is in standby mode. If it is in standby mode, continue with Step 3. If it is active, complete Step c.

c. If the working card is in standby mode, manually switch traffic back to the working card. In the Selected Group pane, click the working card, then click Manual. Verify that the protect card switches to standby mode and the working card is active. If it does, continue with Step 3. If the protect card is still active, do not continue. Begin troubleshooting procedures or call technical support.

Step 3 From the node view, click the Provisioning > Protection tabs.

Step 4 In the Protection Groups section, click a protection group.

Step 5 Click Delete.


3.6 Setting Up ONS 15454 Timing

SONET timing parameters must be set for each ONS 15454. Each ONS 15454 independently accepts its timing reference from one of three sources:

The BITS (Building Integrated Timing Supply) pins on the ONS 15454 backplane

An OC-N card installed in the ONS 15454. The card is connected to a node that receives timing through a BITS source.

The internal ST3 clock on the TCC+ card

You can set ONS 15454 timing to one of three modes: external, line, or mixed. If timing is coming from the BITS pins, set ONS 15454 timing to external. If the timing comes from an OC-N card, set the timing to line. In typical ONS 15454 networks:

One node is set to external. The external node derives its timing from a BITS source wired to the BITS backplane pins. The BITS source, in turn, derives its timing from a Primary Reference Source (PRS) such as a Stratum 1 clock or GPS signal.

The other nodes are set to line. The line nodes derive timing from the externally-timed node through the OC-N trunk cards.

You can set three timing references for each ONS 15454. The first two references are typically two BITS-level sources, or two line-level sources optically connected to a node with a BITS source. The third reference is the internal clock provided on every ONS 15454 TCC+ card. This clock is a Stratum 3 (ST3). If an ONS 15454 becomes isolated, timing is maintained at the ST3 level.


Caution Mixed timing allows you to select both external and line timing sources. However, Cisco does not recommend its use because it can create timing loops. Use this mode with caution.

3.6.1 Network Timing Example

Figure 3-8 shows an ONS 15454 network timing setup example. Node 1 is set to external timing. Two timing references are set to BITS. These are Stratum 1 timing sources wired to the BITS input pins on the Node 1 backplane. The third reference is set to internal clock. The BITS output pins on the backplane of Node 3 are used to provide timing to outside equipment, such as a Digital Access Line Access Multiplexer.

In the example, Slots 5 and 6 contain the trunk cards. Timing at Nodes 2, 3, and 4 is set to line, and the timing references are set to the trunk cards based on distance from the BITS source. Reference 1 is set to the trunk card closest to the BITS source. At Node 2, Reference 1is Slot 5 because it is connected to Node 1. At Node 4, Reference 1 is set to Slot 6 because it is connected to Node 1. At Node 3, Reference 1 could be either trunk card because they are equal distance from Node 1.

Figure 3-8 An ONS 15454 timing example

3.6.2 Synchronization Status Messaging

Synchronization Status Messaging (SSM) is a SONET protocol that communicates information about the quality of the timing source. SSM messages are carried on the S1 byte of the SONET Line layer. They enable SONET devices to automatically select the highest quality timing reference and to avoid timing loops.

SSM messages are either Generation 1 or Generation 2. Generation 1 is the first and most widely deployed SSM message set. Generation 2 is a newer version. If you enable SSM for the ONS 15454, consult your timing reference documentation to determine which message set to use. Table 3-4 and Table 3-5 show the Generation 1 and Generation 2 message sets.

Procedure: Set up ONS 15454 Timing


Step 1 From the CTC node view, click the Provisioning > Timing tabs ( Figure 3-9).

Step 2 In the General Timing section, complete the following information:

Timing Mode—Set to External if the ONS 15454 derives its timing from a BITS source wired to the backplane pins; set to Line if timing is derived from an OC-N card that is optically connected to the timing node. A third option, Mixed, allows you to set external and line timing references. (Because Mixed timing may cause timing loops, Cisco does not recommend its use. Use this mode with care.)

SSM Message Set—Choose the message set level supported by your network. If a Generation 1 node receives a Generation 2 message, the message will be mapped down to the next available Generation 1. For example, an ST3E message becomes an ST3.

Quality of RES—If your timing source supports the reserved S1 byte, you set the timing quality here. (Most timing sources do not use RES.) Qualities are displayed in descending quality order as ranges. For example, ST3<RES<ST2 means the timing reference is higher than a Stratum 3 and lower than a Stratum 2. See Table 3-4 and Table 3-5 for more information.

Revertive—If checked, the ONS 15454 reverts to a primary reference source after the conditions that caused it to switch to a secondary timing reference are corrected.

Revertive Time—If Revertive is checked, indicate the amount of time the ONS 15454 will wait before reverting back to its primary timing source.

Step 3 In the BITS Facilities section, complete the following information:


Note The BITS Facilities section sets the parameters for your BITS1 and BITS2 timing references. Many of these settings are determined by the timing source manufacturer. If equipment is timed through BITS Out, you can set timing parameters to meet the requirements of the equipment.


State—Set the BITS reference to IS (In Service) or OOS (Out of Service). For nodes set to Line timing with no equipment timed through BITS Out, set State to OOS. For nodes using External timing or Line timing with equipment timed through BITS Out, set State to IS.

Coding—Set to the coding used by your BITS reference, either B8ZS or AMI.

Framing—Set to the framing used by your BITS reference, either ESF (Extended Super Frame, or SF (D4) (Super Frame). SSM is not available with Super Frame.

Sync Messaging—Check to enable SSM.

AIS Threshold—Sets the quality level where a node sends an Alarm Indication Signal (AIS) from the BITS 1 Out and BITS 2 Out backplane pins. When a node times at or below the AIS Threshold quality, AIS is sent (used when SSM is disabled or frame is SF).

Step 4 Under Reference Lists, complete the following information:


Note Reference lists define up to three timing references for the node and up to six BITS Out references. BITS Out references define the timing references used by equipment that can be attached to the node's BITS Out pins on the backplane. If you attach equipment to BITS Out pins, you normally attach it to a node with Line mode because equipment near the External timing reference can be directly wired to the reference.


NE Reference—Allows you to define three timing references (Ref 1, Ref 2, Ref3). The node uses Reference 1 unless a failure occurs to that reference, in which case, the node uses Reference 2. If that fails, the node uses Reference 3, which is typically set to Internal Clock. This is the Stratum 3 clock provided on the TCC+. The options displayed depend on the Timing Mode setting.

Timing Mode set to External—options are BITS1, BITS2, and Internal Clock.

Timing Mode set to Line—options are the node's working optical cards and Internal Clock. Select the cards/ports that are directly or indirectly connected to the node wired to the BITS source, that is, the node's trunk cards. Set Reference 1 to the trunk card that is closest to the BITS source. For example, if Slot 5 is connected to the node wired to the BITS source, select Slot 5 as Reference 1.

Timing Mode set to Mixed—both BITS and optical cards are available, allowing you to set a mixture of external BITS and optical trunk cards as timing references.

BITS 1 Out/BITS 2 Out—Define the timing references for equipment wired to the BITS Out backplane pins. Normally, BITS Out is used with Line nodes, so the options displayed are the working optical cards. BITS 1 and BITS 2 Out are enabled as soon as BITS-1 and BITS-2 facilities are placed in service.

Note Refer to the Cisco ONS 15454 Troubleshooting and Maintenance Guide for timing-related alarms.



Procedure: Set Up Internal Timing

If no BITS source is available, you can set up internal timing by timing all nodes in the ring from the internal clock of one node.


Caution Internal timing is Stratum 3 and not intended for permanent use. All ONS 15454s should be timed to a Stratum 2 or better primary reference source.


Step 1 Log into the node that will serve as the timing source.

Step 2 In the CTC node view, click the Provisioning > Timing tabs.

Step 3 In the General Timing section, enter the following:

Timing Mode—Set to External.

SSM Message Set—Set to Generation 1.

Quality of RES—Set to DUS.

Revertive—Is not relevant for internal timing; the default setting (checked) is sufficient.

Revertive Time—The default setting (5 minutes) is sufficient.

Step 4 In the BITS Facilities section, enter the following information:

State—Set BITS 1 and BITS 2 to OOS (Out of Service).

Coding—Is not relevant for internal timing. The default (B8ZS) is sufficient.

Framing—Is not relevant for internal timing. The default (ESF) is sufficient.

Sync Messaging—Checked

AIS Threshold—Is not available.

Step 5 In the Reference Lists section, enter the following information

NE Reference

Ref1—Set to Internal Clock.

Ref2—Set to Internal Clock.

Ref3—Set to Internal Clock.

BITS 1 Out/BITS 2 Out—Set to None

Step 6 Click Apply.

Step 7 Log into a node that will be timed from the node set up in Steps 1-4.

Step 8 In the CTC node view, click the Provisioning > Timing tabs.

Step 9 In the General Timing section, enter the same information as entered in Step 3, except for the following:

Timing Mode—Set to Line.

3.7 Viewing ONS 15454 Inventory

The Inventory tab ( Figure 3-10) displays information about cards installed in the ONS 15454 node including part numbers, serial numbers, hardware revisions, and equipment types. The tab provides a central location to obtain information and to determine applicability of ONS 15454 Product Change Notices (PCNs) and Field Service Bulletins (FSBs). Using the ONS 15454 export feature, you can export inventory data from ONS 15454 nodes into spreadsheet and database programs to consolidate ONS 15454 information for network inventory management and reporting.

Figure 3-10 Displaying ONS 15454 hardware information

The Inventory tab displays the following information about the cards installed in the ONS 15454:

Location—The slot where the card is installed

Eqpt Type—Equipment type the slot is provisioned for, for example, OC-12 or DS-1

Actual Eqpt Type—The actual card that is installed in the slot, for example, OC12 IR 4 1310 or DS1N-14


Tip You can pre-provision a slot before the card is installed by right-clicking the slot in node view and selecting a card type.


HW Part #—Card part number; this number is printed on the top of the card

HW Rev—Card revision number

Serial #—Card serial number; this number is unique to each card

CLEI Code—Common Language Equipment Identifier code

Firmware Rev—Revision number of the software used by the ASIC chip installed on the card

3.8 Viewing CTC Software Versions

CTC software is pre-loaded on the ONS 15454 TCC+ cards; therefore, you do not need to install software on the TCC+. When a new CTC software version is released, you must follow procedures provided by the Cisco Technical Assistance Center (TAC) to upgrade the ONS 15454 software.

When you upgrade CTC software, the TCC+ stores the older CTC version as the protect CTC version, and the newer CTC release becomes the working version. You can view the software versions that are installed on an ONS 15454 by selecting the Maintenance tab followed by the Software subtab. Select these tabs in node view to display the software installed on one node. Select the tabs in network view to display the software versions installed on all the network nodes.
