This chapter explains how to read and understand SNMP MIB as it relates to the Cisco ONS 15216 EDFA2. This chapter is a reference of all ONS 15216 EDFA2 SNMP commands that are used in a network management system (NMS). For provisioning the ONS 15216 EDFA2, see "Provisioning with ASH and SNMP."
5.1 SNMP Overview
Simple Network Management Protocol (SNMP) is an application-layer communication protocol that allows network devices to retrieve and modify the value of management information, as well as provide event notification to a NMS.
The ONS 15216 EDFA2 SNMP implementation uses proprietary and standard Internet Engineering Task Force (IETF) MIBs to convey inventory, fault, and performance management information.
SNMP allows limited management of the ONS 15216 EDFA2 by a generic, third-party SNMP manager (for example, HP OpenView Network Node manager [NNM] or Open Systems Interconnection [OSI] NetExpert).
The ONS 15216 EDFA2 supports SNMP Version 1 (SNMPv1) and SNMP Version 2c (SNMPv2c) protocols.
5.1.1 SNMP Components
An SNMP-managed network consists of three primary components:
•
Managed devices
•
•
A managed device is a network node that contains an SNMP agent and resides on an SNMP-managed network. Managed devices collect and store management information and use SNMP to make this information available to management systems that use SNMP. Managed devices include routers, access servers, switches, bridges, hubs, computer hosts, and network elements such as the ONS 15216 EDFA2.
5.1.2 ONS 15216 EDFA2 SNMP Elements
The following three SNMP elements are used with the ONS 15216 EDFA2:
•
•
•
The SNMP elements are shown in Figure 5-1.
Figure 5-1 SNMP Elements
5.1.2.1 SNMP Agent
An agent is an entity that assumes an operation role to receive, process, and respond to requests, as well as generated event reports. The SNMP agent gathers data from the MIB, which is the repository for device parameter and network data. To respond to requests, the agent must have network management information access. To generate reports, an agent must be notified of internal events.
Cisco provides both an SNMP agent (installed on the ONS 15216 EDFA2) and SNMP MIB to monitor the ONS 15216 EDFA2. The SNMP agent software and MIB are pre-installed on each module.
Figure 5-2 shows the relationship between the SNMP agent and the MIB.
Figure 5-2 SNMP Agent and MIB
5.1.2.2 SNMP MIBs
The SNMP MIBs are files written in ASN.1 syntax. The MIBs specify what ONS 15216 EDFA2 information needs to be controlled and monitored. The MIBs are pre-installed on the SNMP agent and are accessible via the CLI. Table 5-1 lists the proprietary MIBs for the ONS 15216 EDFA2.
The ONS 15216 EDFA2 also supports the RFC MIBS listed in Table 5-2. Note that some attributes and tables from these MIBS are not applicable or not implemented in the ONS 15216 EDFA2.
The CERENT-15216-EDFA-MIB.mib and other MIBs can also be installed on a third-party SNMP manager located at a network management center. The SNMP manager at the network management center or the SNMP manager, accessible via the CLI, uses the SNMP MIBs to communicate with the SNMP agent.
5.1.2.3 SNMP Manager
The ONS 15216 EDFA2 comes with a pre-installed SNMP manager accessible via the CLI. This SNMP manager can be accessed and used to communicate with the SNMP agent that is also pre-installed on each ONS 15216 EDFA2. This manual displays examples of issuing SNMP commands to the amplifier using the built-in SNMP manager.
SNMP managers from third-party vendors running on a separate computer located at a network management center are often used to manage network elements. If a third-party SNMP manager is used, it must be able to communicate with the SNMP agent pre-installed on the ONS 15216 EDFA2.
If a third-party SNMP manager is used, it is assumed that the SNMP manager is pre-installed prior to the SNMP MIB installation. Each vendor-specific SNMP manager has an unique set of instructions for SNMP MIB installation. For directions on loading the SNMP MIBs, refer to SNMP manager documentation.
Cisco does not provide or recommend a standard third-party SNMP manager.
5.1.3 SNMP MIBs and Message Types
SNMP operations can be quite powerful. A manager can retrieve or modify the value of management information accessible by an agent, an agent can report an event to a manager, and the manager can inform another manager of the value of management information on an agent. Using retrieval and modification operations, a manager can cause an agent to perform an action or execute a command. The manager can also create new and delete existing instances of management information.
A MIB is a hierarchically-organized collection of information. Network management protocols, such as SNMP, gain access to these MIBs. MIBs consist of managed objects and are identified by object identifiers (OID).
The ONS 15216 EDFA2 SNMP agent communicates with an SNMP management application (a third-party application or the built-in SNMP manager) using SNMP messages. Table 5-3 describes SNMP operation types.
5.1.4 Command Syntax Using the SNMP Agent
Although Cisco has its own separate SNMP manager (Cisco Transport Manager [CTM]), management of the ONS 15216 EDFA2 is also possible using the built-in SNMP manager via the command line in the ASH shell, as described in the "6.6 SNMP Commands" section on page 6-14. The example commands and command syntax described in this manual are based on using the built-in ONS 15216 EDFA2 SNMP manager through the ASH shell CLI.
Commands can be issued via Telnet over a LAN or directly through the RS-232 (EIA/TIA-232) port on the module. (See "Installation" for more information.) After setting up a connection to the module and entering a password and user name, the following prompt appears:
ash:hostname:ONS15216 EDFA2>To communicate with the module using SNMP, the command must begin with "snmp". To view a list of possible SNMP operations, enter "snmp" followed by a space and press the Tab key. (See Example 5-1.)
Example 5-1 snmp Command Followed by the Tab Key

5.2 Enabling SNMP Remote Management Community Strings
SNMP communities are groupings of workstations and servers (or gateways) that can manage the ONS 15216 EDFA2. NMSs use SNMP communities to enforce security. SNMP enforces security through password-like community strings. Access to the SNMP agent and the ONS 15216 EDFA2 can be limited by both IP address and community string.
The CLI SNMP manager (local SNMP manager) must be used to setup remote management (via a Telnet connection or terminal server). A third-party, vendor-specific SNMP manager cannot be used to setup remote management.
The process for setting up community entries consists of:
The ONS 15216 EDFA2 has the two default community strings listed in Table 5-4.
Table 5-4 Default Community Strings
public
read operations for all MIBs
private
read and write operations for all MIBs
The privileges assigned to the default strings can be modified or new communities with custom privileges can be created.
5.2.1 Creating a View
The following command describes how to set a view entry. A view defines and restricts the MIB attributes that a particular community can access. The view entry and the community entry are set to factory defaults. Users should consult with the Cisco TAC before modifying these settings.
5.2.1.1 Set View Entry
Command Types
snmp row set local cerent15216EdfaViewEntry
Syntax Description
snmp row set local cerent15216EdfaViewEntry view_index_# subtree
To create a community entry, a view must first be created. A MIB view can restrict the MIBs that a particular community can access. To create a view, type the command. view_index_# is an integer (1 to 2048) assigned to this view entry and subtree is the MIB subtree to which this view applies. Multiple view entries can be used for each view index.
This command creates a new row in the ViewEntry table. The SNMP manager prompts the user for each attribute.
To display a list of possible values, press the Spacebar followed by the Tab key. (See Example 5-3.)
Example 5-3 cerent15216EdfaViewEntry Set Command
ash:hostname:ONS15216 EDFA2> snmp row set local cerent15216EdfaViewEntry 1 cerentcerent15216EdfaViewMask '0'Hcerent15216EdfaViewType includedcerent15216EdfaViewStatusactivenotInServicenotReadycreateAndGocreateAndWaitdestroycerent15216EdfaViewStatus createAndGoash:hostname:ONS15216 EDFA2> snmp row display local cerent15216EdfaViewEntry 1 sampleCLASS cerent15216Edfa-AGENT-MIB.cerent15216EdfaViewEntry ::={cerent15216EdfaViewIndex = 1;cerent15216EdfaViewSubtree = { sample };cerent15216EdfaViewMask = '00'H;cerent15216EdfaViewType = included;cerent15216EdfaViewStatus = active;};Access to the ONS 15216 EDFA2 can be restricted by IP address or community string using this command.
Table 5-5 describes the command and MIB view prompts.
5.2.2 Creating a Community Entry
SNMP communities are groupings of workstations and servers (or gateways) that can manage the ONS 15216 EDFA2. NMSs use SNMP communities to enforce security. Because access to the SNMP agent is controlled by a community entry, every SNMP agent must be configured to recognize one or more community names, and to provide the appropriate level of access to managers according to the community name. The following commands describe the commands for displaying or setting community entries. Users should consult with the Cisco TAC before modifying these settings.
5.2.2.1 Set CommunityEntry
Command Types
snmp row set local cerent15216EdfaCommunityEntry
Syntax Description
snmp row set local cerent15216EdfaCommunityEntry community_index_#
After creating a view, use the snmp row set local cerent15216EdfaCommunityEntry command to create a community entry for that view.
The SNMP manager prompts the user for each attribute. Press the Spacebar and then the Tab key after a prompt to view possible data inputs ( Example 5-4). Refer to Table 5-6 for information concerning data for each prompt.
Example 5-4 cerent15216EdfaCommunityEntry Set Command
ash:hostname:ONS15216 EDFA2> snmp row set local cerent15216EdfaCommunityEntry 3cerent15216EdfaCommName ""cerent15216EdfaCommViewIndex 0cerent15216EdfaCommPrivileges 35cerent15216EdfaCommSrcIPAddr 0.0.0.0cerent15216EdfaCommNetMask 0.0.0.0cerent15216EdfaCommStatus 0cerent15216EdfaCommStatus OBJECT-TYPESYNTAX INTEGER{active(1),notInService(2),notReady(3),createAndGo(4),createAndWait(5),destroy(6)}MAX-ACCESS read-createDESCRIPTION::= { cerent15216EdfaCommunityEntry 7 }Table 5-6 displays the definitions for the community entry values.

5.2.2.2 Display CommunityEntry
Command Types
snmp row display local cerent15216EdfaCommunityEntry
Syntax Description
snmp row display local cerent15216EdfaCommunityEntry community_index_#
After creating a community string, use this command to view its parameters. The number in the command refers to the community index number created in the previous section.
Example 5-5 cerent15216EdfaCommunityEntry Display Command
ash:hostname:ONS15216 EDFA2> snmp row display local cerent15216EdfaCommunityEntry 1CLASS cerent15216Edfa-AGENT-MIB.cerent15216EdfaCommunityEntry ::={cerent15216EdfaCommIndex = 1;cerent15216EdfaCommName = "private";cerent15216EdfaCommViewIndex = 1;cerent15216EdfaCommPrivileges = 255;cerent15216EdfaCommSrcIPAddr = 0.0.0.0;cerent15216EdfaCommNetMask = 255.255.255.255;cerent15216EdfaCommStatus = active;};Table 5-7 displays the decimal values for the following SNMP operations.
For example, 255 is the sum of all decimal values and specifies access to all SNMP operations. This sum is the default private community. 247 is the sum for all SNMP operations with the exception of the Set operation. This sum is the default public community.

The cerent15216Edfa.mib contains several key tables that are used to review and provision the ONS 15216 EDFA2. The following tables are listed and described in the following sections:
•
•
5.4.1 ActionOpGroup
The cerent15216EdfaActionOpGroup table is used to perform operations on the agent. Table 5-8 lists the table variables.
5.4.2 AgentControlGroup
The cerent15216EdfaControlGroup table is used to control the agent. Table 5-9 lists the table variables.
5.4.3 AlarmEntry
The cerent15216EdfaAlarmEntry table is used to display and control alarms. The associated table command provides a summary of all alarms. Table 5-10 describes the table variables.
5.4.4 BootEntry
The cerent15216EdfaBootEntry table is used to determine the boot source image for the bootable modules. The table contains up to four entries, and the module tries these sources in turn until an image is successfully loaded. Table 5-11 lists the table variables.
5.4.5 BootImageEntry
The cerent15216EdfaBootImageEntry table contains the boot and running software image name and revision information for each bootable module. Table 5-12 lists the table variables.
5.4.6 CfgGroup
The cerent15216EdfaCfgGroup table is used to set or get alarm threshold configuration. The associated table command provides a summary of all alarm thresholds. See Table 5-13 for variable definitions. For more information on alarm thresholds, see the "Set Alarm Thresholds" section.
Use the snmp attribute set local cerent15216EdfaOpSaveConfig perform command to save changes.
5.4.7 FfsFileEntry
The cerent15216EdfaFfsFileEntry table contains status information about the files within the file system. Table 5-14 lists the table variables.
5.4.8 FfsOpGroup
The cerent15216EdfaFfsOpGroup table contains information on performing operations on the Flash File System. Table 5-15 lists the table variables.
5.4.9 LogEventControl
The cerent15216EdfaLogEventControl table controls the event log. Table 5-16 lists the table variables.
5.4.10 LogEventEntry
The cerent15216EdfaLogEventEntry table contains the log information for each event. Table 5-17 lists the table variables.
5.4.11 OpGroup
The cerent15216EdfaOpGroup table is used to display or set operation actions, such as saving configuration or loading new software. The individual variables in Table 5-18 are generally used instead of the table command. That is, when performing a cutover command, the user would use the snmp attribute set local cerent15216EdfaOpCutover perform command.
5.4.12 OverallControl
The cerent15216EdfaOverallControl table allows the user to display and configure overall gain and pre-attenuation. Table 5-19 describes cerent15216EdfaOverallControl variables.
5.4.13 OverallStatusGroup
The cerent15216EdfaOverallStatusGroup table allows users to display the input and output of the ONS 15216 EDFA2 amplifier. Table 5-20 describes cerent15216EdfaOverallStatusGroup table variables.
Note
5.4.14 PumpCfgEntry
The cerent15216EdfaPumpCfgEntry table is used to set or get laser pump control mode configuration. The associated table command displays a settings summary or allows you to set pumps. See Table 5-21 for variable definitions. The factory default pump control mode for the ONS 15216 EDFA2 is Constant Gain Temperature Compensated. Cisco recommends that users contact the Cisco TAC prior to changing this mode of operation.
5.4.14.1 Changing the Pump Control Mode
For Constant Gain Temperature Compensated, Constant Pump Current, Constant Pump Power, or idle modes, the system automatically sets the second pump to the same mode when either pump is set.
Constant Output Power mode is only valid for pump 2. If pump 2 is set to Constant Output Power Mode, pump 1 is automatically set to Constant Pump Power mode with an internally calculated value.
Warning
To set the ONS 15216 EDFA2 to Constant Pump Current mode, use the following steps:
Step 1
a.
b.
Step 2
Step 3
a.
b.
Example 5-6 shows how to set the ONS 15216 EDFA2 to Constant Pump Current mode and then set it back to Constant Gain Temperature Compensated mode. (Setting pump 1 or 2 to Constant Gain Temperature Compensated mode sets both pumps to that mode.)
Example 5-6 Setting Mode to Constant Pump Current and then Back to Constant Gain Temperature Compensated

To change the control value for Constant Gain Temperature Compensated mode, the user must set a new value of cerent15216EdfaConstGainOverallGain.
Constant Output Power mode is only valid for pump 2. To change the control value for pump 2, the user must set the new value of cerent15216EdfaPumpCfgConstOutPower for pump 2. When Constant Output Power mode is set for pump 2, pump 1 is automatically set to Constant Pump Power mode with a value that is internally calculated.
To change the control value for Constant Pump Current mode, the user must set new values of cerent15216EdfaPumpCfgConstPumpCurrent for both pumps.
To change the control value for Constant Pump Power mode, the user must set new values of cerent15216EdfaPumpCfgConstPumpPower for both pumps.
For example, to change the value for Constant Pump Current mode, use the following steps:
Step 1
a.
b.
Step 2
Step 3
a.

For example, if the pump control mode is constGainTempComp, then a value of 229 is actually 22.9 dB.
1 In Constant Gain Temperature Compensated mode, the value of the cerent15216EdfaPumpStatusGain variable should always be around 23 dB. This variable is the internal amplifier module gain. The cerent15216EdfaPumpStatusGain variable should not be confused with the cerent15216EdfaConstGainOverallGain variable that is used to set the gain of the ONS 15216 EDFA2. The cerent15216EdfaPumpStatusGain is the value of the gain of the amplification module only, it does not take into account the VOA (variable optical attenuator) attenuation. If you try to calculate the gain using the values of the PumpStatusOutPowerdBm - PumpStatusInPowerdBm you will not get the exact PumpStatusGain value. A more complex calculation is required to get the gain value. It needs to take ASE (amplified spontaneous emission) into account. This variable will be more dominant when the input power to the amplifier is low.
5.4.16 RtcDateAndTime
The cerent15216EdfaRtcDateAndTime table allows the user to set the date and time. When setting the local time of day, set the time zone first, set the DST offset second, and set the local time last. 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.
Table 5-23 describes the variables.
5.4.17 SromIpMgmtGroup
The cerent15216EdfaSromIpMgmtgroup table provides the IP setup information. Table 5-24 describes the variables.
5.4.18 VersionGroup
The cerent15216EdfaVersionGroup table allows users to display the currently loaded image and the image to be loaded after cutover. Table 5-25 describes cerent15216EdfaVersionGroup table variables.

This attribute is not required when operating in factory default Constant Gain Temperature Compensated mode. Setting of the loss of output power alarm deviation is only necessary when the amplifier is used in Constant Output Power mode.
This attribute is used to set the amount by which the output power must vary from the threshold set point before the alarm is activated. This attribute, in conjunction with the loss of output power alarm threshold and hysteresis, enables notification of network operations personnel if the output power of the ONS 15216 EDFA2 drops below a level that would impact proper operation of the optical network.
Typically, network operations personnel should set the loss of output power alarm deviation at a value that is appropriate for the intended network application so that the alarm condition is meaningful. Consult with the Cisco TAC to determine the deviation value for your application. As a guideline, Cisco recommends that the loss of output power alarm deviation value be set at 2 dB. The module triggers an alarm if it detects a signal level of 2 dB below the current output power alarm level threshold value set for the amplifier.
When the ONS 15216 EDFA2 is set to Constant Gain Temperature Compensated mode (factory default), the value for the loss of output power alarm threshold cannot be changed. To display the loss of output power alarm deviation and other power and temperature alarm data, use the snmp table display local cerent15216EdfaCfgGroup command as shown in Example 5-14.

Command Types
snmp attribute get local cerent15216EdfaLpoutHysteresis
Syntax Description
snmp attribute get local cerent15216EdfaLpoutHysteresis
This attribute is not required when operating in factory default Constant Gain Temperature Compensated mode. Setting of the loss of output power alarm deviation is only necessary when the amplifier is used in Constant Output Power or Constant Pump Power modes of operation.
This attribute is used to set the amount by which the output power must increase from the threshold setpoint before the alarm is cleared. This attribute, in conjunction with the loss of output power alarm threshold and deviation, enables efficient processing and clearing of the alarm condition.
Typically, network operations personnel should set the loss of output power alarm hysteresis at a value that is appropriate for the intended network application so that the alarm condition is meaningful. Consult with the Cisco TAC to determine the hysteresis value for your application. As a guideline, Cisco recommends that loss of output power alarm hysteresis value be set at 0.2 dB. The module clears the alarm if it detects a signal level of 0.2 dB above the current output power alarm level threshold value set for the amplifier.
When ONS 15216 EDFA2 is set to Constant Gain Temperature Compensated mode (factory default), the value for loss of output power alarm threshold cannot be changed. To display the loss of output power alarm deviation and other power and temperature alarm data, use the snmp table display local cerent15216EdfaCfgGroup command as shown in Example 5-14.

5.7 Summary of SNMP Alarms and Events
Alarm priorities can be configured (cerent15216EdfaAlarmCfgPriority), so the default values are provided in the tables below. Table 5-28 summarizes the ONS 15216 EDFA2 SNMP alarms.
Table 5-28 SNMP Alarms
1
lcrnt1
Excessive pump current for pump 1. Drive current greater than 95% of end of life value. Current must drop to 90% of end of life value for alarm to clear.
Minor
2
lcrnt2
Excessive pump current for pump 2. Drive current greater than 95% of end of life value. Current must drop to 90% of end of life value for alarm to clear.
Minor
3
ltmp1
Pump 1 laser temperature out of range. Chip temperature deviating more than 10 degrees C from the manufacturer-defined setpoint.
Minor
4
ltmp2
Pump 2 laser temp. out of range. Chip temperature deviating more than 10 degrees C from the manufacturer-defined setpoint.
Minor
5
lpout
Loss of output power. EDFA output power is deviating more than the value of cerent15216EdfaLpoutDeviation from the value of cerent15216EdfaLpoutSetpoint. This alarm is only valid for constOutputPower mode.
Major
6
lpin
Loss of input power (signal). EDFA input power is below the value of cerent15216EdfaLOSThreshold.
Major
7
gain
Gain out of range. Gain has deviated more than 1.25 dB from the setpoint in constGainTempComp mode. This alarm is also triggered if the input power goes outside the manufacturer-defined range by more than 0.15 dB.
Major
8
ctmp
The case temperature out of the threshold range.
Minor
9
powerBusA
The Power Bus A voltage is out of the threshold range. The power bus threshold has a 1.5V tolerance and a 1.0V hysteresis. There is a ±1.5V inaccuracy in the ONS 15216 EDFA2 voltage measurement.
Minor/Critical1
10
powerBusB
The Power Bus B voltage is out of the threshold range. The power bus threshold has a 1.5V tolerance and a 1.0V hysteresis. There is a ±1.5V inaccuracy in the ONS 15216 EDFA2 voltage measurement.
Minor/Critical1
11
dbBackup
A database backup is in progress.
Minor
12
dbRestore
A database restore is in progress.
Minor
13
swDownload
A TFTP software download is in progress.
Minor
1 If the power system is in simplex mode, a power bus alarm is Critical by default. If the power system is in duplex mode, a single power bus alarm is Minor by default, and if an alarm is raised on both power buses, the second alarm is Critical.
