2.1  Setting up TL1 Communication

The period during which a user is logged into the ONS 15454 SDH is called a session. There are three options you can use to open a session (login):

Cisco Transport Controller (CTC)

Telnet

Craft interface

The TL1 password (PID) is masked when accessing a TL1 session using any of these options. When you logout of any of these options, you are closing a session. The ONS 15454 SDH allows a maximum of 20 (19 telnet sessions and one craft session) concurrent TL1 sessions using any one or any combination of the options listed above. For information on issuing commands to multiple nodes, see the "TL1 Gateway" section.

2.1.1  Open a TL1 session

Use the following procedures to open a TL1 session via the CTC, telnet, or craft interface. In the procedures the Activate and Cancel User commands are shown in their input format. For more detailed command information about these and other commands and messages, refer to the Cisco ONS 15454 SDH TL1 Command Guide.

Open a TL1 Session Through CTC


Step 1 From the PC connected to the ONS 15454 SDH, start Netscape or Internet Explorer.

Step 2 Enter the IP address of the node you want to communicate with in the Netscape or Internet Explorer Web address (URL) field.

Step 3 Log into the CTC. The IP address at the title bar should match the IP address of the node you entered in Step 2.

Step 4 Once logged into the CTC, there are two ways to open a TL1 session:

Click Tools > Open TL1 Connection, or

Click on the Open TL1 Connection buttonon the toolbar.

Step 5 From the Select Node dialog box choose the node you want to communicate with.

Step 6 Click OK.

A TL1 interface window opens. There are three sub-windows in the TL1 interface window: Request History, Message Log/Summary Log, and TL1 request. Type commands in the TL1 request window. You will see responses in the Message log window. The Request History window allows you to recall previous commands by double-clicking on them.

Step 7 Verify that the Connect button is selected (grayed out).

Step 8 Type the Activate User command in the TL1 request window to open a TL1 session:

ACT-USER:[<TID>]:<UID>:<CTAG>::<PID>; and press Enter.


Note You must press Enter after the semicolon in each TL1 command, or the command will not be issued.


Step 9 Type the Cancel User command in the TL1 request window or press the Disconnect button to close a TL1 session:

CANC-USER:[<TID>]:<USERID>:<CTAG>; and press Enter.


Open a TL1 Session Through Telnet

To access TL1 commands in a telnet session over a craft interface or a LAN connection (TCC2/TCC2P card front panel or backplane pins) you can choose from several ports. Port number 3082 is a raw TCP/IP port; it will not echo and it will not prompt the user. Port number 3083 is a telnet port that uses the telnet protocol and associated telnet escape sequences. Port number 2361 is supported for backward compatibility with earlier releases and has the same behavior as Port 3083 (telnet port). Use the following procedure with PCs running Windows operating systems.


Step 1 At the DOS prompt, type cmd and press Enter. (The same steps can also be done from a Unix prompt).

Step 2 At the DOS command prompt type:

TELNET <NODE IP ADDRESS OR NODE NAME> <PORT NUMBER> and press Enter.

The Node IP address or Node Name refers to the IP address or Node Name of the node you want to communicate with. Port number is the port (2361, 3082, or 3083) where TL1 commands are understood. If the connection is successful, a screen opens with a prompt.

Step 3 Type the Activate User command to open a TL1 session:

ACT-USER:[<TID>]:<UID>:<CTAG>::<PID>;


Note When the semicolon is typed, the command is issued immediately.


Step 4 Type the Cancel User command to close a TL1 session:

CANC-USER:[<TID>]:<USERID>:<CTAG>;


Open a TL1 Session Through Craft Interface

The TCC2/TCC2P card has two built-in interface ports for accessing the ONS 15454 SDH. With one RJ-45 LAN connection you can access the system using a standard browser interface. In the browser interface, you can perform local and remote Operations, Administration, Maintenance, and Provisioning
(OAM&P) functions and open a VT100 emulation window to enter TL1 commands. If a browser is not available, you can access the system using a nine-pin RS-232 port. The RS-232 port supports VT100 emulation which allows TL1 commands to be entered directly without a browser. For instructions on how to install the TL1 craft interface, refer to the Cisco ONS 15454 SDH Procedure Guide.


Step 1 Connect the serial cable to the RS-232 port on the active TCC2/TCC2P card.

Step 2 Configure the terminal emulation software (Hyperterminal):

Terminal emulation = vt100

Bits per second = 9600

Parity = None

Stop BITS = 1

Flow control = None

Step 3 Press Enter. An angle bracket prompt (>) appears.

Step 4 At the > prompt, type the Activate User command to open a TL1 session:

ACT-USER:[<TID>]:<UID>:<CTAG>::<PID>;


Note When the semicolon is typed, the TL1 command is issued immediately.


Step 5 Type the Cancel User command to close a TL1 session:

CANC-USER:[<TID>]:<USERID>:<CTAG>;


2.2  Test Access

The test access (TACC) feature allows a third-party Broadband Remote Test Unit (BRTU) to create non-intrusive test access points (TAPs) to monitor the circuits on the ONS 15454 SDH for errors. The test access feature also allows the circuit to be split (intrusive), so that the transmission paths can be tested for bit errors via the use of various bit test patterns. The two BRTUs supported by the ONS 15454 SDH are the Hekimian/Spirent BRTU-93 (6750) and the TTC/Acterna Centest 650.

The test access functionality provides TL1 commands for creating and deleting TAPs, connecting or disconnecting TAPs to circuit cross-connects and changing the mode of test access on the ONS 15454 SDH. You can view test access information in CTC; in node view click the Maintenance > Test Access tabs.

A TAP provides the capability to connect the circuit under test to a BRTU. This connection initially provides in-service monitoring capability to permit the tester to determine that the circuit under test is idle. The monitor connection should not disturb the circuit under test. The access point and remote test unit (RTU) also provide the capability of splitting a circuit under test. A split consists of breaking the transmission path of the circuit under test. This is done out of service. The two sides of the access point are called the Equipment (E) and Facility (F) directions. For a 4-wire or 6-wire circuit, the transmission pairs within the access point are defined as the A and B pairs. The circuit under test should be wired into the access point so the direction of transmission on the A pair is from E to F, and the transmission direction for the B pair is from F to E (Figure 2-1).

Figure 2-1 Circuit With No Access (Dual FAD TAP)

A dual FAD (facility access digroup) TAP uses twice the bandwidth of the circuit under test. This can be specified by the TAPTYPE parameter as shown in ED-<MOD2> command syntax in the "ED-<rr>" section. The values are SINGLE/DUAL. It defaults to DUAL.

A single FAD TAP uses half the bandwidth as that of the dual FAD, for example, it will use the same bandwidth as the circuit accessed for the TAP creation. This can be specified by the TAPTYPE parameter as shown in the "ED-<rr>" section. The values are SINGLE/DUAL. The MONEF, SPLTEF, LOOPEF modes are not supported by Single FAD TAPs (Figure 2-2).

2.2.2  TAP Creation and Deletion

TL1 supports commands to create, delete, connect, change, retrieve, and disconnect TAPs.

2.2.2.1  ED-<rr>

The edit command (ED-<rr>) is used to change an existing Port/VC to a TAP.

ED- (E1, E3, DS3I, VC12, VC3, VC4, VC42C, VC43C, VC44C, VC48C, VC416C, VC464C):[<TID>]:<AID>:<CTAG>[:::TACC=<TACC>],[TAPTYPE=<TAPTYPE>];

Edit an existing Port/ VC and change it to a TAP so it can be used when requesting TACC connections. This includes an optional parameter TACC=n that defines the port/VC as a test access point with a selected unique TAP number. This TAP number will be used when requesting test access connections to circuit cross-connects under test. The TAP creation will fail if the port/VCn already has a cross-connect on it.

The TAPTYPE parameter values are SINGLE/DUAL. The MONEF, SPLTEF, and LOOPEF modes are not supported by single FAD TAPs. It defaults to DUAL.


Note This command generates a REPT DBCHG message.



Note The alarms and conditions on TACC paths can be retrieved by the RTRV-ALM-ALL or RTRV-ALM-<MOD2> commands.



Note The TAP is a persistent object; it will exist even after the user has logged out of the TL1 session.


The following apply to TAP numbers:

1. A TAP number is an integer in the range of 1-999. When TACC=0 is specified, the TAP is deleted (if already present).

2. A TAP number is unique across E1, E3, DS3I, VC12, VC3, VC4, VC42C, VC43C, VC44C, VC48C, VC416C, VC464C TAPs in the system.

3. A TAP number is not editable.

2.2.2.2  ED-E1

When an ED-E1 is executed with a specified TACC value for a given E1 port/facility, a DFAD (dual facility access digroup) is created by using the specified port/facility and the consecutive port/facility. The command in Example 2-1 creates a DFAD on FAC-1-1 and FAC-1-2.

Example 2-1 ED-E1::FAC-1-1:12:::TACC=1;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;


Note These ports/facilities cannot be used for the creation of cross-connections until the TAP is deleted.


2.2.2.3  ED-E3

When an ED-E3 is executed with a specified TACC value for a given E3 port/facility, a DFAD is created by using the specified port/facility and the consecutive port/facility. The command in Example 2-2 creates an E3 DFAD on FAC-2-1 and FAC-2-2.

Example 2-2 ED-E3:: FAC-2-1:12:::TACC=2;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;


Note These ports/facilities cannot be used for the creation of cross-connections until the TAP is deleted.


2.2.2.4  ED-DS3I

The ED-DS3I command is used for DS3 access on a DS3I card. When an ED-DS3I is executed with a specified TACC value for a given DS3I, a DFAD is created by using the specified facility and the consecutive port/facility. The command in Example 2-3 creates DFAD on FAC-16-1 and FAC-16-1.

Example 2-3 ED-DS3I::FAC-16-1:12:::TACC=3;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;


Note These ports/facilities cannot be used for the creation of cross-connections until the TAP is deleted.


2.2.2.5  ED-VC4n

When an ED-VC4n is executed for a TACC it assigns the VC path for the first 2 -way test access connection and VC+1 as the 2nd 2-way connection. Similarly, for VC42c, VC43c, VC44c, VC48c, VC416c next consecutive VC of same width is chosen. The TAP creation will fail if either of the consecutive VC's are not available. The command in Example 2-4 creates a TAP on VC4-5-1-1 and VC4-5-1-2.

Example 2-4 ED-VC4::VC4-5-1-1:12:::TACC=4;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;


Note These VC paths cannot be used for creation of cross-connects until the TAP is deleted.


The command in Example 2-5 creates a VC48C Dual TAP on VC4-6-1-1 and VC4-6-1-25.

Example 2-5 ED-VC48C::VC4-6-1-1:12:::TACC=5;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;


Note These VC paths cannot be used for creation of cross-connects until the TAP is deleted.


2.2.2.6  ED-VC12

When an ED-VC12 is executed for a TACC a VC12 TAP is created. The specified VC12 AID is taken as the first VC12 connection, and the consecutive VC12 connection is used for as the second path for the TAP.

For example on a E1 card:

Example 2-6 ED-VC12::VC12-1-1-1-1-1:12:::TACC=6;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;

This creates a VC12 TAP on VC12-1-1-1-1-1 and VC12-1-1-1-2-1. These VC's cannot be used for creation of cross-connects until the TAP is deleted.

2.2.2.7  ED-VC3

When an ED-VC3 is executed for a TACC a VC3 TAP is created. The specified VC3 AID is taken as the first VC3 connection, and the consecutive VC3 connection is used for as the second path for the TAP.

For example on an E3 card:

Example 2-7 ED-VC3::VC3-1-1-1:12:::TACC=6;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;

This creates a VC3 TAP on VC3-1-1-1 and VC3-1-1-2. These VC's cannot be used for creation of cross-connects until the TAP is deleted.

2.2.3  Connect Test Access Points

The CONN-TACC command (CONN-TACC-<rr>) is used to make a connection between the TAP and the circuit or cross-connect under test.

CONN-TACC-(E1, E3, DS3I, VC12, VC3, VC4, VC42c, VC43c, VC44c, VC48c, VC416c, VC464c):[<TID>]:<AID>:<CTAG>::<TAP>:MD=<MD>;

Connect the port/VC4n/VC3 defined by <AID> to the port/VC4n/VC3 defined by the <TAP> number. The Mode of Test Access to the circuit/cross-connect is specified by <md>. The modes can be either of monitor (non-intrusive), Split or Loop (intrusive) modes. The various modes are described in the "Test Access Configurations" section.


Note The connection is maintained only for the duration of the TL1 session. (Non-persistent).



Note The TAP number is displayed at the output if the CONN-TACC command completes successfully.

Note The access mode cannot be changed if the TAP is not connected.



Note This command generates a REPT DBCHG message.


2.2.5  Retrieving Test Access Point Information

2.2.5.1  RTRV-<rr>


Note A generic ALL AID would behave similarly to an ALL AID such as, SLOT-ALL or FAC-1-ALL for all the RTRV-rr commands that support a generic ALL AID.


RTRV- (E1, E3, DS3I, VC12, VC3, VC4, VC42c, VC43c, VC44c, VC48c, VC416c, VC464c):[<TID>]:<AID>:<CTAG>;

These commands are modified to include the return of a TAP number if the requested <AID> is defined as a TAP. An optional TACC=<TAPNUMBER> will appear in the output list if the requested <AID> is defined as a TAP. The TAPTYPE is supported starting with R4.6.

Example 2-10 RTRV-E1::FAC-1-1:D;

VA454E-96 2003-04-24 20:06:46
M D COMPLD
"FAC-1-1::LINECDE=HDB3,FMT=E1-MF,TACC=1,TAPTYPE=DUAL,
SOAK=32:UNLOCKED,"
;

Table 2-3 shows parameters for the RTRV-<rr> command.

Table 2-3 RTRV-<rr> Parameters

Parameter
Definition

<TID>

Note If a TAP is not removed the VC bandwidth will be stranded.


2.2.8  Test Access Configurations

Figure 2-3 Single Node View (Node 1)

ED-VC4::VC4-1-1-1:90:::TACC=1;

Changes VC4 1 & VC4 2 on slot 1 to a TAP. The CTAG is 90. Sets the TAP number to 1.

CONN-TACC-VC4::<AID for E or F depending on md>:91::1:MONE

Connects the <AID> to the TACC defined by TAP 1 on the E side. CTAG is 91


Note The connection made in the CONN-TACC command can use MONE to connect to the F side <AID>. The <AID> provided designates the E side and the other automatically becomes the F side. For example, if an <AID F> is supplied to a MONE connection then the top line would be connected to the other side of the path, or what is shown in the diagram as the F side. Once a CONN-TACC is set up these designations cannot change until a DISC-TACC or another CONN-TACC command is executed. The connection is really based on the <AID> supplied.

Note The I and J connections above are TAPS in figure 1 but normal connections in this configuration.


2.2.9  Test Access Mode Definitions

The following diagrams show what the different test access modes <MD> refer to. Figure 2-5 shows a circuit with no access (dual FAD TAP), Figure 2-6 shows a circuit with no access (single FAD TAP), followed by all the modes. The QRS can be generated by an outside source, for example, the empty connection of the BRTU.

MONE, MONF, and MONEF access modes are non-service effecting and can be applied to an locked (in service) port state.

LOOPE, LOOPF, SPLTE, SPLTF, SPLTEF, SPLTA, SPLTB, and SPLTAB access modes are intrusive and only be applied to a circuit/port that is in the Unlocked_Maintenance (Out of Service, Maintenance) port state. The NE will change the state of the circuit under test to Unlocked_Maintenance during the period of TACC and restore it to the original state once the connection between the TAP and the circuit is dropped.

2.2.10  Unmapped AID Test Access Point Connections

The Cisco ONS 15454 SDH also supports connections to unmapped AIDs (unmapped circuits). The TAPs can be connected to an unmapped AID (an AID that does not have a cross-connect on it). The access modes supported are MONE, SPLTE and LOOPE. Example 2-14 creates a TAP on VC4-5-1-1.

Example 2-14 ED-VC4::VC4-5-1-1:12:::TACC=1;

DV9-99 1970-01-02 03:16:11
M 12 COMPLD
;

Example 2-15 creates an unmapped AID connection with a MONE access mode. VC4-5-1-3 does not have a cross-connect on it. VC4-5-1-3 becomes unusable until the connection is disconnected by the DISC-TACC command.

Example 2-15 CONN-TACC-VC4::VC4-5-1-3:12::1:MD=MONE;

DV9-99 1970-01-02 02:51:54
M 12 COMPLD

;


Note The <AID> provided in the CONN-TACC command designates the E side and the other automatically becomes the F side.



Note In the case of all 1-way circuits (1-way, SNCP_HEAD, SNCP_DROP, SNCP_DC, SNCP_EN): If the <AID> specified is the source AID, the direction is designated as From E in the above table. If the <AID> specified is the destination AID or the drop side, the direction is designated as From F in the above table.


Examples:

The following examples assume a VC TAP is already created with TAP number = 1.

2.2.10.1  1-Way Circuit

Example 2-16 ENT-CRS-VC3::VC-5-1,VC-5-2:12::1WAY;
DV9-99 1970-07-01 20:29:06
M 12 COMPLD;

Example 2-17 CONN-TACC-VC3::VC-5-1:12::1:MD=MONF;

M 12 DENY
EANS
VC-5-1
/*INCORRECT TAP MODE*/

The <AID> specified in the above CONN-TACC command is the source AID for the 1-way circuit. In this case only MONE and SPLTA modes are allowed because there is no B path in the case of a 1-way circuit (see Table 2-6).

Example 2-18 CONN-TACC-VC3::VC-5-1:12::1:MD=MONE;
DV9-99 1970-01-01 20:30:09
M 12 COMPLD

Example 2-19 DISC-TACC::1:12;
DV9-99 1970-01-01 20:30:20
M 12 COMPLD
;

However if the <AID> specified is the destination AID as shown below, the modes allowed are MONF and SPLTB.

Example 2-20 CONN-TACC-VC3::VC-5-2:12::1:MD=MONF;
DV9-99 1970-01-01 20:30:32
M 12 COMPLD


NoteThe same examples apply for SNCP_HEAD, SNCP_DROP, SNCP_DC and SNCP_EN which are all 1-way circuits.

The connections are made only to the working path irrespective of which path is currently active.


2.2.10.2  2-Way Circuits

For 2-way circuits all the modes are allowed as shown in Table 2-6 and the same applies for SNCP_SNCP and SNCP circuit types. In the case of SNCP_SNCP and SNCP circuits the working path is connected irrespective of which path is currently active.

2.2.10.3  Unmapped AID

As explained in the "Unmapped AID Test Access Point Connections" section, connections can be made to an <AID> without a cross-connect on it. The modes supported are MONE, SPLTE and LOOPE as shown in Table 2-6.

2.3  TL1 Gateway

This section describes the TL1 Gateway and provides procedures and examples for implementing TL1 Gateway on the ONS 15454 SDH.

2.3.1  Gateway Network Element Topology

You can issue TL1 commands to multiple nodes via a single connection through the TL1 Gateway. Any node can serve as a Gateway Network Element (GNE), End-Point Network Element (ENE), or Intermediate Network Element (INE). A node becomes a GNE when a TL1 user connects to it and enters a command destined for another node. An ENE is an end node because it processes a TL1 command that is passed to it from another node. An INE is an intermediate node because of topology; it has no special hardware, software, or provisioning.

To implement the TL1 Gateway, use the desired ENE's TID in the ACT-USER command to initiate a session between the GNE and the ENE. Once a session is established you need to enter the ENE's TID in all of the subsequent commands that are destined for the ENE. From the GNE, you can access several remote nodes which become the ENEs. The ENEs are the message destinations or origins. The INE handles the DCC TCP/IP packet exchange.

The GNE Session is the connection that multiplexes TL1 messages between the OSS/craftsperson and the GNE. The GNE demulitplexes incoming operations support system (OSS) TL1 commands and forwards them to the remote ENE. The GNE also multiplexes incoming responses and autonomous messages to the GNE Session. The ENE Session is the connection that exchanges messages between the GNE and the remote ENE. Figure 2-25 shows the GNE topology.

Figure 2-25 Example of a GNE Topology

2.3.2  TL1 Sessions

Each NE can support up to a maximum of 20 concurrent communication sessions (connections from an OS/NE to the GNE). The TL1 connections can be made through telnet sessions from the LAN or from the craft/serial port connection on the NE. One TL1 session is reserved for the active serial port connection. The remaining 19 sessions are used for TL1 sessions through the LAN (wire-wrap, active serial port, or DCC). Table 2-7 shows the number of serial port and LAN connections per platform.

2.3.3  TL1 Gateway and ENE Sessions

Only a limited number of TL1 users logged into an NE at any given time can establish sessions to other ENEs. The active serial port sessions are reserved and can always become a GNE session. The number of ENE sessions is based on the number of gateway communications sessions (GNE sessions).

Each NE can support up to 12 concurrent communication gateway sessions, depending on the NE type. The maximum number of ENE sessions also varies depending on the NE type.

You can dynamically distribute the maximum number of ENE sessions to balance the number of concurrent gateway communication sessions. The GNE treats the concurrent gateway communication sessions and ENE/GNE limit as a resource pool. It continues to allocate resources until the pool is exhausted. When the pool is exhausted, the GNE returns an "All Gateways in Use" message or an "All ENE Connections in Use" message.


Note The speed of the TL1 gateway and the maximum number of connections are limited by shared system resources, such as CTC, CTM, etc. The response time is slow as connections are increased and activity on these connections increases. Alarm storms, additional users, netwoork latency, etc. also increase response time.


Cisco ONS 15600 allows up to 500 ENEs per GNE session from Software Release 6.0 and higher.

The gateway resource pools for each platform are shown in Table 2-8.

Note Every ENE over an OSI DCC is equivalent to two ENEs over an IP DCC. If you use a combination of IP and OSI ENE sessions, it is important to remember that the maximum number of ENEs supported is equal to the number if IP ENEs plus two times the number of OSI ENEs (IP + 2*OSI).

For example, for Cisco ONS 15454 GNE, if you use 100 ENEs over IP DCC, then you can use only 38 ENEs over OSI DCC (100 + 2*38 = 176). For Cisco ONS 15310-MA GNE, if you use 30 ENEs over OSI DCC, then you can use only 52 ENEs over IP DCC (2*30+52 = 112).

2.3.4  Implementing TL1 Gateway


Note Issuing commands to specific nodes in the network is accomplished by entering a unique node name in the TID field in each TL1 message. The TID field is synonymous with the name of the node and is the second token in a TL1 command.


The following procedures demonstrate TL1 Gateway on a four-node ring (without TL1 Gateway in Figure 2-26 and with TL1 Gateway in Figure 2-27), where:

Node 0 is the GNE.
Node 1 is the ENE 1.
Node 2 is the INE 2.
Node 3 is the ENE 3.

Figure 2-26 Four-Node Ring Without TL1 Gateway

Figure 2-27 Four-Node Ring With TL1 Gateway

Log Into a Remote ENE


Step 1 Telnet or connect through the serial port to Node 0, which will become the GNE.

Step 2 To connect to the ENE 1 node, enter the TL1 login command using the following input example:

ACT-USER:NODE1:USERNAME:1234:PASSWORD;

The GNE forwards the login to ENE 1. After successful login, ENE 1 sends a COMPLD response.

Step 3 When you are logged into ENE 1, enter the following TL1 login command to connect to ENE 3:

ACT-USER:NODE3:USERNAME:1234:PASSWORD;

The GNE forwards the login to ENE 3. After successful login, the ENE 3 sends a COMPLD response.


Forward Commands by Specifying the ENE TID (Node 1 or Node 3)

When you are logged into ENE 1 and ENE 3, enter a command and designate a specific TID, as shown in the following example:

RTRV-HDR:NODE1::1; will retrieve the header of Node 1 and

RTRV-HDR:NODE3::3; will retrieve the header of Node 3.

Receive Autonomous Messages from the Remote ENE

To receive autonomous messages from the remote ENE, you must log into the remote ENE. When you are logged in, you will begin to receive autonomous messages. The source of the message is identified in the header of the message.

Log Out of a Remote ENE

To disconnect from a remote ENE, you must use the CANC-USER command as follows:

CANC-USER:NODE1:USERNAME:1;

will disconnect ENE 1 and

CANC-USER:NODE3:USERNAME:3;

will disconnect ENE 3.

The GNE forwards the logout to the remote ENEs. The GNE/ENE TCP session is closed.

2.4  Ring Provisioning

This section provides information and sample procedures for setting up virtual container (VC) circuits over existing subnetwork connection protection ring (SNCP) and multiplex section shared protection ring (MS-SPRing) configurations using TL1, including:

SNCP topology

SNCP cross-connections

Ring-to-ring interconnection

1-way drop and continue

2.4.1  SNCP Topology

No special configuration of the physical SNCP topology is required other than connecting the fibers to the desired ports on the desired nodes. The east and west paths must exit a node at different ports (to ensure link diversity), but there are no other physical topology restrictions.

ONS 15454 SDH networks give you the option to set up path-protected mesh networks (PPMNs). PPMNs extend the protection scheme of an SNCP from the basic ring configuration to the meshed architecture of several interconnected rings. For more information about PPMN, refer to the Cisco ONS 15454 SDH Procedure Guide.

2.4.2  SNCP Cross-Connections

To create an SNCP cross-connection using TL1, you only need to designate it as a 1-way or 2-way cross-connect. The access identifier (AID) must be more explicit. For example, to create a 1-way SNCP circuit over the network with nodes A, B, C, and D and segments A-B, B-D, A-C, C-D as shown in Figure 2-28, enter the following commands (Node A is the source node and Node D is the destination node):

ENT-CRS-VC1:A:FROM,TO1&TO2:CTAG1::1WAY;
ENT-CRS-VC1:B:FROM,TO:CTAG2::1WAY;
ENT-CRS-VC1:C:FROM,TO:CTAG3::1WAY;
ENT-CRS-VC1:D:FROM1&FROM2,TO:CTAG4::1WAY;

Figure 2-28 Network Configured With a 1-Way SNCP Circuit

2.4.3  Ring-to-Ring Interconnection

In the following examples, the form "5/1/1" represents "Slot 5, Port 1, VC 1." For VCs, add the normal VC Group and VC ID extensions. These examples also assume that the slots/ports have been autoprovisioned (via a plug-in event) and that the ports involved have been placed into the in-service (IS) state using a port configuration command, for example, ED-STMn.

For the examples in this section, both rings traverse the same node; therefore, only a single cross-connection is required to create the ring-to-ring connection. This is shown in Figure 2-29. The node named "Cisco" is in the nexus.

Figure 2-29 Network Map With Cisco Node Showing Ring-to-ring Interconnection

2.4.4  SNCP to SNCP Connection Example

Ring 1 = SNCP

Ring 2 = SNCP

This example, illustrated in Figure 2-30, uses an STM-3-4 to feed Ring 2. Ring 1 can have any STM-N trunk card, but the trunk card is most likely a single-port STM-16 or STM-4.


Note The VC calculation formula is: (((Port # -1)*Number of VC per port)+VC#).
VC 12/3/2 maps to VC-12-8 (((3-1)*3) +2).


Figure 2-30 SNCP-to-SNCP Connection Specifications Through The Cisco Node

Use the command ENT-CRS-VC1:CISCO:VC-5-1&VC-6-1,VC-12-8&VC-13-8:CTAG1::2WAY;
to create a selector between 5/1/1 and 6/1/1 which is bridged to Ring 2 (12/3/2 and 13/3/2), as shown in Figure 2-31.

Figure 2-31 Selector Between 5/1/1 and 6/1/1

The command also creates a selector between 12/3/2 and 13/3/2 to a bridge to Ring 1 (5/1/1 and 6/1/1), as shown in Figure 2-32.

Figure 2-32 Selector Between 12/3/2 and 13/3/2

2.4.5  SNCP to Two-Fiber MS-SPRing Connection Example

Ring 1 = SNCP

Ring 2 = Two-fiber MS-SPRing

This example, illustrated in Figure 2-33, uses a SNCP end-point with a drop on a two-fiber MS-SPRing and the west span of the two-fiber MS-SPRing (Ring 2) for the active path of the circuit. The example also uses multiport addressing for Ring 2 and is based on a multiport STM-4 card (this is only important for computing the VC AID for multiport cards) where 13/3/2 = VC-13-26 and where
26 = (((3-1)*12) +2).

Figure 2-33 SNCP to Two-Fiber MS-SPRing

Use the command ENT-CRS-VC1:CISCO:VC-5-1&VC-6-1,VC12-26:CTAG2::2WAY;
to create a selector between 5/1/1 and 6/1/1 which connects to 12/3/2 on Ring 2, as shown in Figure 2-34.

Figure 2-34 Selector Between 5/1/1 and 6/1/1

The command also creates a bridge from 12/3/2 to Ring 1 (5/1/1 and 6/1/1), as shown in Figure 2-35.

Figure 2-35 Bridge From 12/3/2 to Ring 1

In this configuration a two-fiber MS-SPRing switch can automatically reconnect the selector output to the protection path on the east port (12/3/2 assuming STM-4) if necessary.

2.4.6  Two-Fiber MS-SPRing to SNCP Connection Example

Ring 1 = Two-fiber MS-SPRing

Ring 2 = SNCP

This example, illustrated in Figure 2-36, uses a SNCP end-point with a drop on a two-fiber MS-SPRing and uses the east span of the two-fiber MS-SPRing (Ring 1) for the active path of the circuit. For VC addressing, the SNCP is an STM-1 (for example,VC-13-8).

Figure 2-36 Two-Fiber MS-SPRing to SNCP

Use the command ENT-CRS-VC1:CISCO:VC-6-1,VC-12-8&VC-13-8:CTAG3::2WAY;
to create a bridge from 6/1/1 to Ring 2 (12/3/2 and 13/3/2), as shown in Figure 2-37.

Figure 2-37 Bridge From 6/1/1 to Ring 2

The command also creates a selector between 12/3/2 and 13/3/2 to Ring 1 (6/1/1) as shown in Figure 2-38.

Figure 2-38 Selector Between 12/3/2 and 13/3/2 to Ring 1

2.4.7  Two-Fiber MS-SPRing to Two-Fiber MS-SPRing Connection Example

Ring 1 = Two-fiber MS-SPRing

Ring 2 = Two-fiber MS-SPRing

All protection for a two-fiber MS-SPRing interconnecting to a two-fiber MS-SPRing is performed at the line level. You can make the connection with a 2-way cross-connect from a VC on the working side of the two-fiber MS-SPRing span of Ring 1 to a VC on the working side of a two-fiber MS-SPRing span on Ring 2. The connections can be east-to-east, east-to-west, west-to-east, and west-to-west. This example, illustrated in Figure 2-39, uses Ring 1 west to Ring 2 east and assumes an STM-12-4 in Slots 12 and 13 for subtending to a two-fiber MS-SPRing (Ring 2).

Figure 2-39 Two-Fiber MS-SPRing to Two-Fiber MS-SPRing

Use the command ENT-CRS-VC1:CISCO:VC-5-1,VC-13-26:CTAG4::2WAY;
to create a 2-way connection from 5/1/1 to 13/3/2 as shown in Figure 2-40.

2.4.8  Two-Fiber MS-SPRing to Four-Fiber MS-SPRing Connection Example

Ring 1 = Two-fiber MS-SPRing

Ring 2 = Four-fiber MS-SPRing

All protection for a two-fiber MS-SPRing interconnecting to a four-fiber MS-SPRing is performed at the line level. You can make the connection with a simple 2-way cross-connect from the appropriate side, east or west, of the two-fiber MS-SPRing to the working fiber of the appropriate side, east or west, of the four-fiber MS-SPRing, as shown in Figure 2-41.

Figure 2-41 Two-Fiber MS-SPRing to Four-Fiber MS-SPRing

Use the command ENT-CRS-VC1:CISCO:VC-1-1,VC-5-1:CTAG5::2WAY;
to create a 2-way connection from 1/1/1 to 5/1/1, as shown in Figure 2-42.

Figure 2-42 2-Way Connection from 1/1/1 to 5/1/1

In the event of a failure, the software will automatically switch the traffic to the appropriate line and path.

2.4.9  SNCP to Four-Fiber MS-SPRing Connection Example

Ring 1 = SNCP

Ring 2 = Four-fiber MS-SPRing

This example uses the west span of the four-fiber MS-SPRing (Ring 2) for the active path of the circuit. The example also assumes that the four-fiber MS-SPRing travels over STM-64 spans, as shown in Figure 2-43.

Figure 2-43 SNCP to Four-Fiber MS-SPRing

Use the command ENT-CRS-VC1:CISCO:VC-1-1&VC-2-1&VC-5-190:CTAG6::2WAY;
to create a selector between 1/1/1 and 2/1/1 to Ring 2 (5/1/190), as shown in Figure 2-44.

Figure 2-44 Selector Between 1/1/1 and 2/1/1 to Ring 2 (5/1/190)

The command also creates a bridge from 5/1/190 to Ring 1 (1/1/1 and 2/1/1), as shown in Figure 2-45.

Figure 2-45 Bridge from 5/1/190 to Ring 1 (1/1/1 and 2/1/1)

2.4.10  1-Way Drop and Continue

The following examples show how to create a 1-way drop and continue cross-connect. The examples use three nodes (Node 1, Node 2, and Node 3) in a ring configuration (Figure 2-46). Node 1 is the source node, Node 2 has the drop and continue, and Node 3 is the destination.

Figure 2-46 1-Way Drop and Continue

Figure 2-47 shows a circuit diagram example of the orientation of AIDs associated with the ENT-CRS command used to establish drop and continue connections.

2.5  PCA Provisioning

You can provision or retrieve protection channel access (PCA) cross-connections on two-fiber and four-fiber MS-SPRing topologies at these supported VC rates: STM-4 (two-fiber only), STM-16, and STM-64. The traffic on the protection channel is referred to as extra-traffic and has the lowest priority level. Extra traffic will be preempted by any working traffic that requires the use of the protection channel.

In a two-fiber MS-SPRing the extra traffic is provisioned on the upper half of the bandwidth path. In a four-fiber MS-SPRing the extra traffic is provisioned on the protect fiber. The PCA provisioning feature allows you to establish the PCA cross-connection on the protection path of the two-fiber MS-SPRing and protection channel of the four-fiber MS-SPRing only when the query is an explicit request.

There are two PCA connection types: 1WAYPCA and 2WAYPCA. The PCA cross-connection is provisioned only when the user provides an explicit request using the ENT-CRS-VCp/VC12 commands. If the cross-connection is a PCA cross-connection, either 1WAYPCA or 2WAYPCA is shown in the CCT field of the RTRV-CRS-VCp/VC12 command output.

1WAYPCA and 2WAYPCA are only used in the TL1 user interface to provide usability and visibility for the user to specify a PCA cross-connection type in the TL1 cross-connection commands.


Note The network must be configured as either a two-fiber or four-fiber STM-4, STM-16, or STM-64 MS-SPRing.



Note The VC path cross-connection can be established with TL1 commands (ENT-CRS-xxx).



Note Because the RTRV-CSR-xxx command does not include the optional CTYPE field to specify a connection type, the output result reports the matched cross-connections based on the queried AID(s); therefore, the retrieved cross-connection inventory can be both PCA and non-PCA cross-connections.


2.5.1  Provision a PCA Cross-Connection

Input format for provisioning a PCA cross-connection:

Example 2-21 ENT-CRS-<PATH>:[<TID>]:<FROM>,<TO>:<CTAG>::[<CCT>][::];
<PATH>::={VC_PATH | VC12}
[<CCT>]::={1WAY, 1WAYDC, 1WAYEN, 2WAY, 1WAYPCA, 2WAYPCA}, it defaults to 2WAY.
{VC_PATH}::={VC3 | VC4| VC42C | VC43C | VC44C | VC48C | VC416C | VC464C}

VC= all the VC bandwidth cross-connections.

VC12=VC12_5 cross-connection.

Input example of provisioning an VC4 PCA cross-connection:

Example 2-22 ENT-CRS-VC4::VC4-1-1,VC4-2-1:123::2WAYPCA;


Note If the [<CCT>] of this cross-connection provisioning command is either 1WAYPCA or 2WAYPCA, and the NONE of both <FROM> and <TO> AID is PCA AID, an IIAC (Input, Invalid PCA AIDs) error message is returned.



Note If sending this command with a non-PCA connection type (CCT), and one (or two) AIDs is/are the PCA AIDs, an IIAC (The PCA AID Is Not Allowed for the Queried CCT Type) error message is returned.


2.5.2  Retrieve a PCA Cross-Connection

Input Format for retrieving a PCA cross-connection:

Example 2-23 RTRV-CRS-[<PATH>]:[<TID>]:<AID>:<CTAG>[::::];<PATH>::=
{VC_PATH | VC12 | VC}

If PATH is VC, it will retrieve all the VC cross-connections based on the queried AIDs.

<AID>={FacilityAIDs, VCAIDs, VC12AIDs, ALL}

Output format of the PCA VCp cross-connection retrieval command:

Example 2-24 "<FROM>,<TO>:2WAYPCA,VC4"

Output format of the PCA VC cross-connection retrieval command:

Example 2-25 "<FROM>,<TO>:2WAYPCA"

2.6  FTP Software Download

The file transfer protocol (FTP) software download feature downloads a software package to the inactive flash partition residing on the TCC2/TCC2P card. FTP software download provides for simplex and duplex TCC2/TCC2P card downloads, success and failure status, and in-progress status at 20% increments.


Note FTP timeout is 30 seconds and is not user-configurable.


2.6.1  COPY-RFILE

The COPY-RFILE command downloads a new software package from the location specified by the FTP URL into the inactive flash partition residing on the TCC2/TCC2P card. COPY-RFILE can also be used to backup and restore the database file.


Note Since Release 5.0, PACKAGE_PATH is relative to your home directory, instead of being an absolute path from the root directory of the NE. If you want to specify an absolute path, start the path with the string '%2F'.


Input format:

Example 2-26 COPY-RFILE:[<TID>]:[<SRC>]:<CTAG>::TYPE=<XFERTYPE>,[SRC=<SRC1>,]
[DEST=<DEST>,][OVWRT=<OVWRT>];

where:

SRC is the type of file being transferred

<XFERTYPE> is the file transfer protocol

<SRC1> specifies the source of the file to be transferred. Only the FTP URL is supported. In a nonfirewall environment the format for the URL is: "FTP://FTTPUSER[:FTP_PASSWORD]]@FTP_HOST_IP[:FTP_PORT]
/PACKAGE_PATH[:TYPE=I]"

where:

FTP_USER is the userid to connect to the computer with the package file

FTP_PASSWORD is the password used to connect to the computer with the package file

FTP_HOST_IP is the IP address of the computer with the package file, DNS lookup of hostnames is not supported

<FTP_PORT> defaults to 21

PACKAGE_PATH is the long path name to the package file starting from the home directory of the logged-in user.

In a firewall environment the hostname should be replaced with a list of IP addresses each separated by a "@" character. The first IP address should be for the computer where the package file is stored. Subsequent IP addresses are for firewall computers moving outward toward the edge of the network until the final IP address listed is the computer that outside users use to first access the network.

For example, if your topology is:

"FTPHOST <-> GNE3 <->GNE2 <-> GNE1 <-> ENE"

the FTP URL is:

FTP://FTP_USER:FTP_PASSWORD@FTP_HOST_IP@GNE3@GNE2@GNE1/
PACKAGE_PATH

SRC1 is a String

DEST specifies the destination of the file to be transferred. The comments for the SRC parameter are also valid here. DEST is a string

If OVWRT is YES, then files are overwritten. Currently only YES is supported. Using a NO value for OVWRT will result in an error message.


NoteFTP is the only allowed file transfer method.

The use of the SWDL and the extended FTP URL syntax are required by the COPY-RFILE syntax.


2.6.2  APPLY

The APPLY command can activate or revert software depending on the version of software loaded on the active and protect flash. An error is returned if attempting to activate to an older software load or trying to revert to a newer software load. If this command is successful the appropriate flash is selected and the TCC2/TCC2P2 card will reboot.

Input format:

Example 2-27 APPLY:[<TID>]::<CTAG>[::<MEM_SW_TYPE>]:

where:

<MEM_SW_TYPE> indicates memory switch action during the software upgrade.

2.6.3  REPT EVT FXFR

REPT EVT FXFR is an autonomous message used to report the start, completion, and completed percentage status of the FTP software download. REPT EVT FXFR also reports any failure during the software upgrade including invalid package, invalid path, invalid userid/password, and loss of network connection.

Note:

1. The "FXFR_RSLT" is only sent when the "FXFR_STATUS" is COMPLD.

2. The "BYTES_XFRD" is only sent when the "FXFR_STATUS" is IP or COMPLD.

Output format:

Example 2-28 SID DATE TIME
A ATAG REPT EVT FXFR
"<FILENAME>,<FXFR_STATUS>,[<FXFR_RSLT>],[<BYTES_XFRD>]"
;

where:

<FILENAME> indicates the transferred file path name and is a string. When a package is being transferred between the FTP server and the controller cards, the filename field will contain the string "active". Following this transfer, if there is a second controller card on the node, the file will be copied over to the second card. While this is happening, REPT EVT FXFR messages will be generated with a filename of "standby".

<FXFR_STATUS> indicates the file transferred status: Start, IP (in progress), or COMPLD.

<FXFR_RSLT> indicates the file transferred result: success or failure. <FXFR_RSLT> is optional

<BYTES_XFRD> indicates the transferred byte count. <BYTES_XFRD> is a string and is optional

2.6.4  Downloading New Software

The following procedure downloads new software to the TCC2/TCC2P card using TL1.

Download New Software


Note Only Superusers can download and activate software.



Step 1 Copy the new software package (15454SDH-0340-X02E-2804.pkg) to an FTP host.

Step 2 Establish a TL1 session with the target NE.

Step 3 Login with the ACT-USER command.

Step 4 Check the working and protect software on the NE by issuing the RTRV-NE-GEN command.

Input example:

Example 2-29 RTRV-NE-GEN:::1;

Output example:

Example 2-30 VA454-94 1970-01-06 22:22:12
M 1 COMPLD
"IPADDR=10.82.87.94,IPMASK=255.255.255.224,DEFRTR=10.82.86.1,
ETHIPADDR=10.82.87.94,ETHIPMASK=255.255.255.224,NAME=VA454-94,
SWER=3.40.00,LOAD=03.40-002G-14.21,PROTSWVER=4.00.00,
PROTLOAD=04.00-X02G-25.07,DEFDESC=\"FACTORY DEFAULTS\""
;

Step 5 Issue the COPY-RFILE command. This command will initiate the download process. Refer to the "COPY-RFILE" section for command syntax.

In the following example the package is located in "/%2FUSR/CET/VINTARA" in the host 10.77.22.199. The userid and passwords are TL1 and CISCO454SDH. The directory path of the package is similar to what you will see during an FTP session.

Example 2-31 COPY-RFILE::RFILE-
PKG:CTAG::TYPE=SWDL,SRC="FTP://TL1:CISCO454SDH@10.77.29.199
/%2FUSR/CET/VINTARA/15454-0340-X02E-2804.PKG";

DEV208 1970-01-10 11:51:57
M CTAG COMPLD
;

Step 6 If any of the parameters are wrong or if the host is not accessible, a REPT EVT FXFR message will report from the following list. A download failure might be due to one or more of the following:

Directory path of the package is invalid or not found

Package is invalid (for example, an ONS 15454 SDH package on an ONS 15327, vice-versa, or an invalid file type)

Package not found on specified path

Userid/password or hostname is invalid

Host is not accessible

Firewall userid/password or host in invalid

Node rebooted/lost connection during download

If software download is already in progress

If the node or the host timed out during FTP protocol

Example 2-32 DEV208 1970-01-10 11:52:02
A 2816.2816 REPT EVT EQPT
"SLOT-11:SFTWDOWN-FAIL,TC,,,,,,,:\"SOFTWARE DOWNLOAD FAILED\",TCC
;

Step 7 If the download is successful the REPT EVT FXFR message will report an active start:

Example 2-33 DEV208 1970-01-10 11:52:15
A 2818,2818 REPT EVT FXFR
"ACTIVE START"
;

Step 8 A SFTDOWN minor alarm is raised to indicate that the software download is in progress. The SFTDOWN alarm will clear when the download is complete.

Example 2-34 DEV208 1970-01--10 11:52:15
* 2817.2817 REPT ALM EQPT
"SLOT-7:MN,SFTWDOWN,NSA,,,,:\"SOFTWARE DOWNLOAD IN PROGRESS\",TCC"
;

Use the in-progress status at any time during the software download to verify the RTRV-NE-GEN command.

Example 2-35 RTRV-NE-GEN

VA454-94 1970-01-06 22:22;12
M 1 COMPLD
"IPADDR=10.82.87.94,IPMASK=255.255.245.0,DEFRTR=10.82.86.1,
ETHIPADDR=10.82.87.94,EHTIPMASK=255.255.254.0,NAME=VA454-94,
SWVER=3.40.00,LOAD=03.40-002G-14-21,PROTSWVER=NONE,
PROTLOAD=DOWNLOADINPROGRESS,DEFDESC=\:FACTORY DEFAULTS\""
;

Step 9 The download progress is reported by the REPT EVT FXFR message which will report a message after every 20% of download is complete as shown:

Example 2-36 DEV208 1970-01-10 11:53:12
A 2820,2820 REPT EVT FXFR
"ACTIVE,IP,,20"
;

DEV208 1970-01-10 11:53:12
A 2820,2820 REPT EVT FXFR
"ACTIVE,IP,,40"
;


DEV208 1970-01-10 11:53:12
A 2820,2820 REPT EVT FXFR
"ACTIVE,IP,,60"
;

DEV208 1970-01-10 11:53:12
A 2820,2820 REPT EVT FXFR
"ACTIVE,IP,,80"
;

Step 10 If the TL1 session times out during download or if the user terminates the TL1 session the download will continue. The download completion can be confirmed by issuing the RTRV-NE-GEN command and verifying the PROTLOAD.

Example 2-37 RTRV-NE-GEN:::1;

VA454-94 1970-01-06 22:22:12
M 1 COMPLD
"IPADDR=10.82.87.94,IPMASK=255.255.255.224,DEFRTR=10.82.86.1,
ETHIPADDR=10.82.87.94,EHTIPMASK=255.255.254.0,NAME=VA454-94,
SWVER=3.40.00,LOAD=03.40-002G-14-21,PROTSWVER=4.00.00,
PROTLOAD=03.40-X02E-28.04,DEFDESC=\:FACTORY DEFAULTS\""
;

Step 11 REPT EVT FXFR confirms the completion of the software download.

Example 2-38 DEV208 1970-01-10 12:01:16
A 2825,2825 REPT EVT FXFR
"ACTIVE,COMPLD,SUCCESS"
;

Step 12 The SFTDOWN alarm clears when the download is complete.

Example 2-39 DEV208 1970-01-10 11:52:15
* 2826,2817 REPT ALM EQPT
"SLOT-7:CL,SFTWDOWN,NSA,,,,:\"SOFTWARE DOWNLOAD IN PROGRESS\",TCC"
;


2.6.5  Activating New Software

After the software is successfully downloaded, the new software which resides in the protect load must be activated to run on the NE. The APPLY command can be used to activate and revert depending on the version of the protect software and the newly downloaded software (refer to the "APPLY" section for correct APPLY syntax).

Activate New Software


Step 1 If the protect software is newer than the working software, activate it as shown:

Example 2-40 APPLY::1::ACT;

DEV208 1970-01-10 13:40:53
M 1 COMPLD
;

An error is reported if a revert is attempted with a newer protect software.

Step 2 If the APPLY command is successful, logout of the TL1 session using the CANC-USER command:

Example 2-41 CANC-USER::CISCO15:1;

VA454-94 1970-01-07 01:18:18
M 1 COMPLD
;

After a successful completion of the APPLY command the NE will reboot and the TL1 session will disconnect. When the NE comes up after the reboot it will be running the new software. Traffic switches are possible during activation.


2.6.6  Remote Software Download/Activation Using the GNE

In a network with SDCC-connected ONS 15454 SDHs, remote download and activation are possible using the GNE/ENE feature supported in TL1. The GNE must be connected by a LAN and the remaining ENEs can download the new software package through fiber from the GNE.

For remote software downloading, complete the steps in the "Download New Software" procedure and the "Activate New Software" procedure, but ensure that the TID in each command is filled with the ENE node name.

Each GNE can support 11 (TCC2/TCC2P) concurrent communication gateway sessions and up to a maximum of 176 (TCC2/TCC2P) ENEs/GNE. For more information on TL1 Gateway, see the"TL1 Gateway" section.

Example 2-42 ACT-USER:NODE1:CISCO15:1;
ACT-USER:NODE2:CISCO15:1;
ACT-USER:NODE3:CISCO15:1;
ACT-USER:NODE4:CISCO15:1;
ACT-USER:NODE5:CISCO15:1;

Five simultaneous software downloads can be initiated using the COPY-RFILE command with appropriate TIDs. All downloads will be independent of each other and download speeds might differ.

Example 2-43 COPY-RFILE:NODE1:RFILE-PKG:CTAG::TYPE=SWDL,SRC="FTP://TL1:
CISCO454@10.77.29.199/USR/CET/VINTARA/15454-0340-X02E-2804.PKG";

COPY-RFILE:NODE2:RFILE-PKG...
COPY-RFILE:NODE3:RFILE-PKG...
COPY-RFILE:NODE4:RFILE-PKG...
COPY-RFILE:NODE5:RFILE-PKG...

Individual REPT EVT FXFR messages can be isolated using the node names. RTRV-NE-GEN also requires the individual node names entered in the TID to see a specific download status.

You can activate the software on all of the nodes using the GNE node.


Note Activate the GNE last, after activating all the ENEs or else ENE connectivity will be lost when the GNE starts to reboot for activation.


Example 2-44 APPLY:NODE1::1::ACT;
APPLY:NODE2::1::ACT;
APPLY:NODE3::1::ACT;
APPLY:NODE4::1::ACT;
APPLY:NODE5::1::ACT;

2.7  Scheduled PM Report

Scheduled performance monitoring (PM) report is a feature that extends the capability of PM reporting for the Cisco ONS 15454 SDH. With scheduled PM report the system automatically and periodically generates the PM report of any specified facility or cross-connection. For more information on performance monitoring, refer to the Cisco ONS 15454 SDH user documentation.


NoteThe current maximum number of schedules allowed to be created for an NE is 1000. If this number of schedules has been created for the NE, an error message "Reach Limits Of MAX Schedules Allowed. Can Not Add More" will be returned if trying to create more schedules on the NE.

Identical schedules for an NE is not allowed. Two schedules are considered identical if they have the same AID, MOD2 type, performance monitor type, performance monitor level, location, direction and time period.

An error message "Duplicate Schedule" is returned if you create a schedule which is a duplicate of an existing schedule. However, if the existing schedule expires (with the parameter <NUMINVL> equal to zero when retrieved by the RTRV-PMSCHED command which means no more performance monitoring report to be sent), then the new schedule with the identical parameter will replace the existing schedule.

When you create a PM schedule, the minimum report interval should not be less than five minutes.


See each command description in the Cisco ONS 15454 SDH TL1 Command Guide for command formats and syntax:

SCHED-PMREPT-<MOD2>

ALW-PMREPT-ALL

RTRV-PMSCHED-<MOD2>

RTRV-PMSCHED-ALL

INH-PMREPT-ALL

REPT PM <MOD2>

2.7.1  Create a PM Schedule and Receive an Autonomous PM Report

1. Issue the SCHED-PMREPT-<MOD2> command to create a PM schedule.

2. Issue the ALW-PMREPT-ALL command to allow the current TL1 session to be able to receive the autonomous PM report.

2.7.2  Manage PM Schedules

1. Create a PM schedule by issuing the SCHED-PMREPT-<MOD2> command.

2. Delete a PM schedule by issuing the SCHED-PMREPT-<MOD2> command with the <NUMREPT> parameter equal to zero.


Note The PM schedules created on a facility or a cross-connect will be automatically deleted if the card or the cross-connect are unprovisioned.


3. Retrieve all the PM schedules created on the node by issuing the RTRV-PMSCHED-ALL command. Retrieve a particular MOD2 type of PM schedule by issuing the RTRV-PMSCHED-<MOD2> command.


Note The system will not automatically delete the schedules that are expired, for example, a schedule is created to report PM 10 times. After 10 PM reports are sent, the schedule is expired. The expired schedule can be identified by its <NUMINVL> field (equal to zero) in the response of RTRV-PMSCHED.


2.7.3  Enable or Disable a TL1 Session to Receive Autonomous PM Reports

1. Enable a TL1 session to receive a scheduled PM report by issuing the ALW-PMREPT-ALL command.


Note By default, a TL1 session is disabled to receive PM reports. The ALW-PMREPT-ALL command enables a TL1 user to receive all the scheduled PM reports from the system, regardless of whether or not the schedule is created by this TL1 user or by any other TL1 user.


2. Disable a TL1 session to receive any scheduled PM report by issuing the INH-PMREPT-ALL command.

2.8  Bridge and Roll

Bridge and Roll functionality allows live traffic to be moved (rolled) from one entity to another. This section provides information and sample procedures for single-rolling, dual-rolling, and protection rolling for one-way or two-way circuits using TL1 commands, including:

Path Level Rolling—Rolls cross-connections at the VC11, VC12, VC3, and VCNc rate for all supported TDM drops (STM1, STM4, STM16, and STM64). Individual rolls are done at the Path Level.

Line Level Rolling—Rolls all cross-connections from one port/facility to another port/facility.

Bulk Rolling—Rolls a subset of cross-connections from one port/facility to another port/facility

There are two roll modes:

In automatic mode, the leg to be rolled is automatically dropped upon detection of a valid input signal on the new path.

In manual mode, the leg to be rolled is retained upon detection of a valid signal on the new path. The leg must be dropped manually.


Caution If you have created a roll on the circuit and it has detected a valid signal, do not cancel it. Cancelling a valid roll will cause a traffic hit of more than 1300 ms. If you want to revert back from a valid roll, complete the roll and use bridge and roll again to roll it back.


Caution Performing bridge and roll on a VC4-64c (STM64c circuit) might cause a traffic hit of 50 ms.


Note The path width rules for creating circuits apply when rolling circuits. For example, if you roll a VC4 starting at VC#1, you cannot roll it to another port and start it at VC#2. You have to start it at VC#1.


2.8.1  Restrictions

The following restrictions apply for bridge and roll using TL1 in this release:

1. Rolling is not allowed on electrical cards or Ethernet cards.

2. Rolling is not allowed on hairpin circuits.

3. Rolling is not allowed on monitor circuits.

4. Rolling is not allowed on any cross-connection that is involved in test access.

5. Rolling is not allowed on any cross-connection that is involved in cross-connect loopbacks.

6. Rolling is not allowed on any port that is involved in facility or equipment loopbacks. This restriction applies to both "roll from" and "roll to."

7. When rolling on a 1+1 protected circuit, the "roll to" cannot be on the protect port of the protection group.

8. Rolling on a (multiplex section-shared provisioning ring) (MS-SPRing) protected circuit cannot violate the rules governing MS-SPRing circuits: a circuit that traverses a MS-SPRing must use the same STS number on the ring between source and destination.

9. Rolling on an MS-SPRing protected circuit will be denied if there is an existing protection switch on the ring. If the protection switch happens after the roll is initiated, the system will not monitor valid signals on the "roll to" path until the protection switching is cleared.

10. Rolling on a subnetwork conncection protection (SNCP) protected circuit cannot violate the rules governing SNCP circuits: SNCP circuits must have one bridge and one selector.

11. The bridge and selector of an SNCP protected circuit cannot be rolled away.

12. In the case of a dual roll on an SNCP protected circuit, both roll points have to be on either the working or protect path of the circuit. For example, you cannot specify one roll point on the working path and the other roll point on the protect path of the circuit being rolled.

13. When rolling on a SNCP protected circuit, the "roll to" cannot be line protected (1+1 or MS-SPRing protected). TL1 can only ensure this on the bridge and selector node, not on the intermediate node.

14. When rolling on a mixed protection circuit, the roll points have to be within the same protection domain.

15. Rolling using TL1 can be performed on a CTC-created cross-connection.


Note If a roll is created using TL1 it cannot be edited or deleted by CTC.


16. Rolling using TL1 can be performed on a TL1 cross-connection.


Note If a roll is created using CTC, it cannot be edited or deleted by TL1.


17. If the intermediate path of a circuit is being rolled away to another circuit, the second circuit cannot carry any live traffic.


Note After a roll is completed, the second circuit will form the new intermediate path of the original circuit.


18. Rolling cannot be performed on low order path tunnel or VC low order path aggregation point (VAP) circuits passing through less than four nodes.

The following restrictions apply for bridge and roll using TL1 VCAT in this release:

1. For non open-ended VCAT circuits, you cannot change the source or destination of the circuit.

2. For open-ended VCAT circuits, you can change the source or destination of the circuit, but only on the open end.

The following restrictions apply for bridge and roll using TL1 common fiber-routed VCAT circuits in this release:

1. Rolling cannot change the common fiber property of a common fiber-routed VCAT circuit.

2. When rolling on a VCAT member circuit, in order not to change the common fiber property of a common fiber-routed VCAT circuit, you can roll the member from one time slot to a different time slot within the same fiber.

2.8.4.2  Create a 1-Way Circuit Dual Roll

In this procedure, both the source and destination nodes are rolled. There are two types of dual rolls:

Dual roll for a single circuit within the same facilities but to a different time slot.

Dual roll for a single circuit from one span card to another span card.


Step 1 Determine which type of roll you want to perform on the source node and follow the steps in the "2-Way Circuit Single Roll and Dual Roll Procedures" section.

Step 2 Determine which type of roll you want to perform on the destination node and follow the steps in the "2-Way Circuit Single Roll and Dual Roll Procedures" section.


2.8.5  Protection Rolling Procedures

To perform protection rolls, follow the procedures in the "2-Way Circuit Single Roll and Dual Roll Procedures" section and the "1-Way Circuit Single Roll and Dual Roll Procedures" section.


Note Before performing a protection roll, either from one protection group to another or within the same protection group, the protection group must already be provisioned.

2.9  Remote Monitoring-Managed PMs

This section describes the retrieval, threshold setting, threshold crossing alerts (TCAs), and scheduled performance monitoring (PM) reporting for all the remote monitoring (RMON)-managed PM data in the Cisco ONS 15454 SDH.

The cards that support RMON PMs include: G1K-4, ML1000-2/ML100T-12, FC_MR-4, MXP_MR_2.5G/MXPP_MR_2.5G, and ML-100T-8/CE-100T-8. The PM types for these cards include Ethernet statistic types defined in standard SNMP/RMON MIB, and also include other statistic types managed by RMON, for example, the Fibre Channel statistic types.

When creating an RMON threshold there are two threshold values that need to be specified. The first threshold is the rising threshold and the other is the falling threshold. There are other parameters that need to be specified when creating the RMON threshold, for example, the startup type and the sample type.


Note There can be more than one threshold defined for each RMON statistic type.


The current bucket is not defined by the RMON. RMON-managed PM only shows the history data of the PMs and the data accumulated since the last time the counters are cleared (RAW-DATA).

In the RMON TCA, the accumulation time period is not the predefined PM bucket accumulation time, such as 15-MIN or 1-DAY. It can be any integer (any time greater than 10 seconds) that is defined when creating the RMON threshold.

2.9.1  RTRV-PM-<MOD2>

The RTRV-PM-<MOD2> command retrieves the RMON-managed PMs.

The TL1 modifiers FSTE/GIGE/POS are used to retrieve the RMON-managed Ethernet PM, if the Ethernet port is a FSTE/GIGE/POS port type. The FC modifier retrieves the RMON-managed Fibre Channel PM.

There are three accumulation time periods for RMON statistics: 1-MIN, 1-HR, and RAW-DATA. For RMON-managed PMs, only history PM buckets and RAW-DATA are supported and there is no current bucket defined for RMON-managed PMs. When RAW-DATA is specified in the input of RTRV-PM, the date and time specified in the input will be ignored. The mondate and montime in the output will be the last time the counters were cleared. RAW-DATA will be the default TMPER value for RMON-managed PM retrieval.

Because RMON PM only supports the history data if the accumulation time period is 1-MIN, 15-MIN, 1-HR, or 1-DAY, you must specify the correct history PM bucket for the RTRV-PM command to succeed.

When retrieving PM, if an unsupported montype is specified, an error message will be returned.

Currently there is no support of LOCN (location) and DIRN (direction) for RMON-managed data statistics.

2.9.2  ENT-RMONTH-<MOD2_RMON>

The ENT-RMONTH-<MOD2_RMON> command creates a threshold type (an entry in the RMON alarm table) for an RMON statistic, for the RMON-managed PMs. An event (TCA) is generated and reported when the threshold is crossed in the appropriate direction during the sampled time period.

More than one threshold can be created by using different parameters (rising/falling threshold), for each montype.

This command applies to G1000, GIGE, FSTE, POS, and FC data objects.

2.9.3  DLT-RMONTH-<MOD2_RMON>

The DLT-RMONTH-<MOD2_RMON> command deletes a threshold type (an entry in the RMON alarm table) created for a montype (RMON statistic type). Because there can be multiple thresholds created for a particular montype, you must specify all the necessary parameters for the threshold, in order to identify the particular threshold to be deleted.

This command applies to G1000, GIGE, FSTE, POS, and FC data objects.

2.9.9  REPT PM <MOD2>

Reports autonomous monitoring statistics as a result of the schedule created by SCHED-PMREPT-<MOD2>.

The LOCN parameter is optional in the output of REPT PM <MOD2> message, and no LOCN information will be given in the output of REPT PM <MOD2>.

2.9.10  REPT DBCHG

Reports any changes on the NE that result from issuing the following commands:

1. ENT-RMONTH-<MOD2>

2. DLT-RMONTH-<MOD2>

Also reports when an RMON PM schedule is created or deleted via the SCHED-PMREPT-<MO2> command.

2.9.11  MONTYPE Defined for Ethernet Statistics and Condition Type for TCA

The names of Ethernet and Fibre Channel montypes are defined exactly as they are defined in the corresponding SNMP MIB statistics group. For example, etherStatsUndersizePkts will be used as the name for the same RMON statistics defined in RFC 1757.

Unlike the PM of other SDH entities (such as VC path, STM), there are two condition types defined for the TCAs of each RMON-managed statistics type (Ethernet or Fibre Channel montype). One condition type is for the rising threshold, and the other is for the falling threshold. For example, there are two condition types for etherStatsUndersizePkts stats type: T-etherStatsUndersizePkts-HT for the rising threshold, and T-etherStatsUndersizePkts-LT for the falling threshold.


Note For platform-specific PM information, refer to the Procedure Guide and Reference Manual of that platform.

2.9.13  Notes for DWDM Card Types

The PM for client port and/or chunk port (OCH) can include both the RMON-managed PM and the SDH PM when theclient payload is provisioned as 1GFC/2GFC/10GFC/1GFICON/2GFICON/GIGE/10GIGE for the following cards:

MXP_2.5G_10G

TXP_MR_10G

TXP_MR_2.5G

TXP_MR_10E

MXP_MR_2.5G

2.9.13.1  Client Port of DWDM Cards

When the client port of a DWDM card is provisioned as 1GFC/2GFC/10GFC/1GFICON/2GFICON/GIGE/10GIGE, the applicable PM for the client port includes both the RMON-managed PM and the SDH PM. Therefore, the behavior of the RTRV-PM-MMOD2>, INIT-REG-<MOD2>, and SCHED-PMREPT-<MOD2> commands is different from the Ethernet or Fibre Channel port of the other cards where only RMON PM is applicable. The differences include:

LOCN and DIRN parameters are applicable to the RTRV-PM-<MOD2>, INIT-REG-<MOD2>, and SCHED-PMREPT-<MOD2> commands because they are applicable to the SDH PM. When the LOCN or DIRN parameter is specified it would only apply to the SDH PM.

Because 1-MIN, 1-HR, or RAW-DATA are not applicable to SDH PM, no SDH PM would be returned in the output of RTRV-PM. If RAW-DATA is specified in the input of the INIT-REG command, no SDH PM counter will be cleared.

When the accumulation time period is specified as 15-MIN or 1-DAY and the PM history bucket is specified as 0 (current bucket), only SDH PM will be returned in the output of the RTRV-PM command. No RMON-managed PM will be included in the output of the RTRV-PM command because RMON PM does not have current bucket.

An SDH PM montype cannot be specified in the input of the INIT-REG command only the SDH PM counters will be cleared. When the ALL montype is specified, both the RMON and the SDH PM counters will be cleared.

The commands used to manage RMON thresholds (ENT-RMONTH, DLT-RMONTH, and RTRV-RMONTH) are only applicable to the RMON PM of the client port. The SDH PM thresholds of the client port are still managed by the SET-TH and RTRV-TH commands. For example, if the client port type of an MXP_MR_2.5G card is provisioned as GIGE, the following commands would be used to create an RMON threshold:

ENT-RMONTH-GIGE::FAC-2-1-1:1::IFINOTETS,,,,1000:RISE=1000,FALL=900;

And the following command would be used to set the SDH PM threshold:

SET-TH-GIGE::FAC-2-1-1:1LBCL-MIN,0.2;

2.9.13.2  OCH Port of the DWDM Card

The OCH port of the TXP_MR_10G and TXP_MR_10E cards include the RMON-managed 8B10B PM as well as the other SDH PM when their client port is provisioned as GIGE/10GIGE or 1GFC/2GFC/10GFC.

The RTRV-PM-OCH, INIT-REG-OCH, SCHED-PMREPT-OCH and REPT PM OCH commands have similar behaviors as mentioned in the "Client Port of DWDM Cards" section.

2.10  Rules for Framing Type Autoprovisioning in CTC Versus TL1

The E1/E3/DS3I cards can autosense framing and set the format accordingly; however, this framing autosense feature can only be set using CTC. Use CTC to set the FMT attribute on E1/E3/DS3I cards to autoprovision. The FMT field will blank out for a few seconds while the card determines the framing mode received by that particular port. The FMT field is set accordingly to unframed, M23, or CBit. If the card is not present (preprovisioned), setting the FMT field to autoprovision will result in the FMT field defaulting to unframed.

The TL1 interface does not support the autoprovision option for the E1/E3/DS3I cards; it only supports unframed, M23, or CBit. If autoprovision is selected from CTC and at the same time the TL1 command RTRV-E3 is issued, the TL1 output will indicate the FMT field as unframed during the time period that the card (if present) is autosensing the frame format. If the card is not present (preprovisioned), the response of the RTRV-E3 command (after CTC sets the FMT to autoprovision) will indicate the FMT field as unframed.
