Chapter 4, Provisioning with ASH and SNMP

This chapter discusses the provisioning procedures for the Cisco ONS 15216 EDFA2 using SNMP and a proprietary command line interface named the ASH shell. See "Provisioning with TL1" for provisioning information using TL1 commands in the TL1 shell.

The provisioning procedure for the ONS 15216 EDFA2 in the ASH shell is as follows:

4.1 Log In via RS-232 (EIA/TIA-232) Port Using HyperTerminal

Step 1

Connect to the RS-232 (EIA/TIA-232) port on the front panel. See the "Serial Connection Procedure" section for line connection and HyperTerminal setup instructions.

Step 2

Open HyperTerminal. (HyperTerminal can be found in the Microsoft Windows Accessories menu.)

By default the ONS 15216 EDFA2 is in TL1 shell, so this step may be required to proceed in ASH shell. When in TL1 shell, the screen opens to a simple prompt (>). To change to ASH shell, log in using the procedure in the "Log In via RS-232 (EIA/TIA-232) Port Using HyperTerminal" section, and then enter the following command at the sid/tid name prompt:

The ONS 15216 EDFA2 should log you off and then bring up the ASH shell login window.

Step 4

Check that the ONS 15216 EDFA2 login window appears as shown in Example 4-1.

Step 6

Press Enter when [Login] becomes highlighted. Example 4-2 displays the login response.

An EIA/TIA-232 link to the ONS 15216 EDFA2 is established. The user can now provision the ONS 15216 EDFA2.

4.2 Set IP Address

Before connecting the ONS 15216 EDFA2 to a LAN, it is mandatory to set the ONS 15216 EDFA2 IP address through a local serial communication interface using the RS-232 (EIA/TIA-232) port on the front of the module.

Step 1

If you do not know the ONS 15216 EDFA2's IP address, subnet mask, gateway address, or host name, contact your network administrator.

Step 2

At the command prompt, enter the snmp row set local cerent15216EdfaSromIpMgmtGroup command (displayed in Example 4-3) and press Enter.

Because row set is being used in this command, the user is prompted row by row to enter the IP address, the subnet mask, the gateway address, and the host name (community ID).

Step 3

The changes must be saved prior to terminating the session. See "Save Changes" section.

4.3 Log In via LAN Port Using Telnet (Optional)

Provisioning of the ONS 15216 EDFA2 can be accomplished entirely through the RS-232 (EIA/TIA-232) port using CLI commands. After an IP address is assigned, it may be easier to provision the ONS 15216 EDFA2 using Telnet or an SNMP manager. A Telnet client is needed for CLI commands over IP. A generic SNMP manager is required for SNMP management over IP. After connecting the ONS 15216 EDFA2 to the network through its RJ-45 LAN port (see "LAN Interface (Ethernet)" section), the user can configure the module to accept SNMP and CLI commands via Telnet using the following procedure:

Specifying port 8023 ensures login through the ASH shell. If no port is specified, the ONS 15216 EDFA2 responds in the shell that the ONS 15216 EDFA2 is set to. (TL1 is the default shell.)

4.4 Set Date and Time

Use the snmp attribute set local cerent15216EdfaRtcDateAndTimeLocalString command to set the date, time, and time zone. Entries must follow this format: "yyyy-m-d,h:m:s.s +h:m". Following the space, the time zone is set as +/- hours from Greenwich Mean Time (GMT) (also designated as universal coordinated time (UTC)) followed by a colon and minutes ahead for daylight savings. For example, Pacific Daylight Time would be -8:60 and Greenwich Mean Time would be +0:0. See Example 4-4.

4.5 Set Power Bus Mode (Simplex or Duplex)

The ONS 15216 EDFA2 allows users to set a simplex (one power source-Bus A) or duplex (redundant power source-Bus A and Bus B) Power Bus mode. Use the snmp attribute set local cerent15216EdfaPowerBusMode command to set the desired Power Bus mode. The default mode is duplex. See Example 4-5.

4.6 Verify Amplifier Operational Status

To ensure that the amplifier is working correctly on the optical level, you must verify the amplifier operational status. Use the snmp table display local cerent15216EdfaOverallStatusGroup command to verify amplifier operational status. Example 4-6 displays the output of this command.

The input power (signal) should be consistent with the input power measured during the optical connection procedure. See the "Optical Connection Procedure" section for more information. The output power value should be 22 dB greater than the input, assuming that the default gain setting is 22 dB.

Note An input power higher than -5 dBm will return a Gain Out of Range alarm that can be cleared by correctly setting the gain value. For more information, refer to Table 2-3.

4.7 Set Gain

To ensure that the ONS 15216 EDFA2 output signal is received by the transceiver in the network element, it is important that the gain is set correctly.

The desired output power per channel is dependent on the number of channels traversed in the amplifier. The user sets the gain of the amplifier depending on the input power (signal) level, the network application, and the required receiver specifications necessary for error-free operation. Gain range is provided in Table 3-1.

To set the amplifier gain, enter the snmp attribute set local cerent15216EdfaConstGainOverallGain gainvalue command, where gainvalue is the desired gain multiplied by ten. For example, if the desired gain is 20 dB, the gainvalue would be set to 200. Example 4-7 shows the command used to set the gain.

Note Prior to changing or implementing gain changes, consult with the Cisco TAC to ensure proper network operation.

4.8 Set Alarm Thresholds

Alarm thresholds are set so that the network operator can be notified when valid alarms occur via the RJ-45 ALARM OUT and RJ-45 LAN ports on the front panel of the ONS 15216 EDFA2. (See Figure 4-1.)

Alarms can be connected to a network operations center (NOC) network management system (NMS) via a network element miscellaneous discrete input and/or office alarm panel/system.

To display the alarm thresholds, use the snmp table display local cerent15216EdfaCfgGroup command ( Example 4-8). This command returns the current alarm threshold default values.

To set the alarm thresholds, use the snmp row set local cerent15216EdfaCfgGroup command. After this command is entered, the user is prompted to modify each attribute, row by row, until all attributes are set. Alarm threshold attributes are described in Table 4-1.

Table 4-1 Alarm Threshold Attribute Definitions
Attribute	Variable Definition	Syntax	Maximum Access	Description
cerent15216EdfaCfgSaved	Configuration saved status	True Value	Read-only	Indicates whether the current configuration has been saved. The value can be true or false. If false, the configuration is not saved.
cerent15216EdfaLpoutSetpoint	Loss of output power setpoint	Integer (0 to 1000, 0 default)	Read-only	Can be disregarded when operating amplifier in Constant Gain Temperature Compensated mode (manufacturer default) and Constant Pump Current mode. Setpoint object is only valid when amplifier is used in Constant Output Power and Idle modes.
cerent15216EdfaLpoutDeviation	Loss of output power deviation	Integer (0 to 1000, 200 default)	Read-write	Can be disregarded when operating amplifier in manufacturer default Constant Gain Temperature Compensated mode. Deviation object is only valid when amplifier is used in Constant Output Power and Idle modes.
cerent15216EdfaLpoutHysteresis	Loss of output power hysteresis	Integer (0 to 1000, 100 default)	Read-write	Can be disregarded when operating amplifier in manufacturer default Constant Gain Temperature Compensated mode. Hysteresis object is only valid when amplifier is used in Constant Output Power and Idle modes.
cerent15216EdfaLOSThreshold	Loss of signal (input power) threshold	Integer (-3100 to -1500, -3000 default)	Read-write	Alarm notifies operations personnel if the optical input signal of the ONS 15216 EDFA2 drops below a level that impacts proper operation of optical network. Set this attribute at a value that is appropriate for the intended application so that the alarm condition is meaningful. Consult with the Cisco TAC to determine the threshold value for your application. As a guideline, Cisco recommends setting the threshold value at 3 dBm below the current input power level of the amplifier. Valid entries are between -3100 and -1500 in dBm times 100. For example, if the total input power of the amplifier is -24 dBm and the loss of input power threshold required is -27 dBm, the loss of input power alarm threshold is -2700.
cerent15216EdfaLOSHysteresis	Loss of signal (input power) hysteresis	Integer (0 to 1000, 100 default)	Read-write	Used to set the amount the input signal must increase above the LOS Threshold level before the alarm is cleared. This attribute, in conjunction with the loss of input signal alarm threshold, enables efficient clearing of alarms. Set this attribute at a value that is appropriate for the application so that the alarm condition will clear when input is stable. Consult with the Cisco TAC to determine the correct value for your application. As a guideline, Cisco recommends setting the value 1 dB above the LOS Threshold value. With this setting, the module will clear the alarm if it detects a signal level of 1 dB above the current LOS Threshold value. Valid entries are between 0 and 1000 and are in dB times 100. For example, if the hysteresis required is 1 dB, the power alarm hysteresis is 100.
cerent15216EdfaCtmpMin	Minimum case temperature	Integer (-10 to 10, -5 default)	Read-write	Alarm notifies operations personnel if the case temperature of the ONS 15216 EDFA2 drops below a level that impacts proper operation of the optical network. The minimum case temperature should be set at a value that is appropriate for the intended application and within product specifications. Consult with the Cisco TAC to determine the correct value for your application. As a guideline, Cisco recommends that minimum case temperature be set at 1�C. Valid entries are between -10 and 10�C.
cerent15216EdfaCtmpMinHysteresis	Minimum case temperature hysteresis	Integer (0 to 10, 1 default)	Read-write	Used to set the amount that the case temperature of the module must rise above the minimum case temperature alarm level before the alarm is cleared. Set the hysteresis at a value that is appropriate for the application so that the alarm condition clears when the input is stable. Consult with the Cisco TAC to determine the correct value for your application. As a guideline, Cisco recommends that the hysteresis value be set at 1�C. Valid entries are between 0 and 10�C. Setting this value to 0 disables this option.
cerent15216EdfaCtmpMax	Maximum case temperature	Integer (20 to 70, 70 default)	Read-write	Alarm notifies operations personnel if the case temperature of the ONS 15216 EDFA2 is at a level that may impact proper operation of the optical network. Set the maximum case temperature at a value that is appropriate for intended application and within product specifications. Consult with the Cisco TAC to determine the correct value for your application. As a guideline, Cisco recommends that maximum case temperature value be set at 50�C. Valid entries are between 20 and 70�C.
cerent15216EdfaCtmpMaxHysteresis	Maximum case temperature hysteresis	Integer (0 to 10, 1 default)	Read-write	Used to set the amount that the case temperature of module must drop below the maximum case temperature alarm level before the alarm is cleared. Set the hysteresis at a value that is appropriate for the application so that the alarm condition clears when the input is stable. Consult with the Cisco TAC to determine the correct value for your application. As a guideline, Cisco recommends setting the value at 1�C. Valid entries are between 0 and 10�C. Setting this value to 0 disables this option.
cerent15216EdfaPowerBusDCVoltageMin	Power bus minimum voltage	Integer (350 to 700, 420 default)	Read-write	Minimum allowable power bus DC voltage. The default minimum power bus voltage is set at -42 VDC. Valid entries are between 350 and 700 and are in negative volts times 10. For example, if the voltage required is -40 VDC, the power bus setting is 400. The power bus threshold has a 1.5V tolerance and a 1.0V hysteresis. There is a potential �1.5V inaccuracy in the ONS 15216 EDFA2 voltage measurement. If the minimum threshold is configured at 420 (-42 VDC), the may raise anywhere between -42 to -40.5V and will not clear until the voltage measures above -43 VDC.
cerent15216EdfaPowerBusDCVoltageMax	Power bus maximum voltage	Integer (350 to 700, 570 default)	Read-write	Maximum allowable power bus DC voltage. The default maximum power bus voltage is set at -57 VDC. Valid entries are between 350 and 700 and are in negative volts times 10. For example, if the voltage required is -57 VDC, the power bus setting is 570. The power bus threshold has a 1.5V tolerance and a 1.0V hysteresis. There is a potential �1.5V inaccuracy in the ONS 15216 EDFA2 voltage measurement. If the maximum threshold is configured at 570 (-57 VDC), the alarm may raise anywhere between -57 to -58.5V and will not clear until the voltage measures below -56 VDC.

4.9 Set Password

To restrict access to the ONS 15216 EDFA2, use the user passwd set command to change the default user password. The password must be a string of up to 10 characters, where at least 2 are non-alphabetic characters and at least 1 is a special character. With the exception of the administrator access level (read_write_admin), users can only modify their own passwords. For additional information on user levels, refer to Table 6-1 on page 6-1. Example 4-9 displays the command.

Note The default user name for the administrator level is CISCO15 with no default password. To start a session for this user name, press Enter.

4.10 Add Users

Use the user entry create command to add new users to the ONS 15216 EDFA2. The syntax is to enter the command followed by the user name and then the access level (read, read_write, read_write_admin) as shown in Example 4-10. The ONS 15216 EDFA2 responds with a request for the password.

Passwords must be an ASCII string of up to 10 characters, where at least 2 are non-alphabetic characters with at least one special character. Special characters are +, #, and %.

4.11 Save Changes

To ensure that the provisioning changes are set, you must save your changes prior to terminating the session. To save changes, use the snmp attribute set local cerent15216EdfaOpSaveConfig perform command ( Example 4-11).

Most SNMP configuration attributes require the above save command before terminating the session (does not apply to TL1 shell). The exceptions to this save requirement (the attributes that are automatically saved) are shown below:

4.12 Log Off

At the end of a session, the user must log off of the ONS 15216 EDFA2. To log off, use the logoff command. This is shown in Example 4-12.

4.13 Back Up System Configuration

The configuration information for the ONS 15216 EDFA2 can be saved in a file for later use or to configure other ONS 15216 EDFA2 units. This file contains manufacturing information about the unit that is being backed up (such as part number and serial number), setup information for the unit (such as IP address and host name), all configuration information (such as alarm thresholds and pump mode), and the user database.

The backup file is saved with cyclic redundancy code (CRC) to ensure data integrity, and the user names, passwords, and other system settings are encrypted for security. The file header, which identifies the node name, IP address, and software version, is text readable. Only the configuration information and user database are copied back to the ONS 15216 EDFA2 during a restore.

4.14 Restore System Configuration

The configuration information for the ONS 15216 EDFA2 can be restored form a file. During this process, all configuration information (such as alarm thresholds and pump mode) and the user database from the file are replaced in the ONS 15216 EDFA2 memory and FFS.

Before the restore begins, a cyclic redundancy code (CRC) check is performed to ensure data integrity.

After the processor reboots, user names and passwords from the new user database must be used for access.
