SNMP MIB Installation and Configuration

This chapter explains how to read and understand SNMP MIB as it relates to the 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 Chapter 4, "Provisioning".

SNMP Overview

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 n NMS.

The ONS 15216 EDFA2 SNMP implementation uses 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.

SNMP Components

An SNMP-managed network consists of three primary components:

•Managed devices

•Agents

•Management systems

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.

ONS 15216 EDFA2 SNMP Elements

The following three SNMP elements are used with the ONS 15216 EDFA2:

•SNMP agent

•SNMP MIB

•SNMP manager

Figure 5-1 SNMP Elements

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 SNMP Agent and MIB

SNMP MIB

The SNMP MIB (CERENT-15216-EDFA-MIB.mib) is a file written in ASN.1 syntax. This MIB specifies what ONS 15216 EDFA2 information needs to be monitored. This MIB is pre-installed on the SNMP agent and is accessible via the CLI.

The cerent15216Edfa.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, (see SNMP Manager) uses the SNMP MIBs to communicate with the SNMP agent.

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.

Third-party, Vendor-Specific SNMP Managers

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.

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.

An 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 5-1 describes SNMP operation types.

Table 5-1 SNMP Operation Types

Operation
Description

get-request

Retrieves a value from a specific variable.

get-next-request

Retrieves the value following the named variable; this operation is often used to retrieve variables in a Table. With this operation, an SNMP agent does not need to know the exact variable name. The SNMP manager searches sequentially to find the needed variable in the MIB.

get-response

The reply to a get-request, get-next-request, get-bulk-request, or set-request sent by an NMS.

get-bulk-request

Similar to a get-next-request, but this operation fills the get-response with up to the max-repetition number of get-next interactions.

trap

An unsolicited message sent by an SNMP agent to an SNMP manager indicating that an event has occurred.

set-request

Sets a value of a specific variable.


Command Syntax Using the SNMP Agent

Although Cisco has its own separate SNMP manager (Cisco Transport Manager [CTM]), communication with the ONS 15216 EDFA2 is also possible using the built-in SNMP manager, its agent, and the MIB. (See Figure 5-1.)

The commands and command syntax displayed in this manual are the result of using the built-in ONS 15216 EDFA2 SNMP manager included with the CLI card.

Commands can be issued via Telnet over a LAN or directly through the RS-232 port on the module. (See Chapter 3, "Installation".) After setting up a connection to the module and entering a password and user name, the following prompt appears:

hostname:ONS15216 EDFA2>

To communicate with the module using SNMP, the command must begin with "snmp".

Note To view a list of possible SNMP operations, enter "snmp" followed by a space and press the Tab key.

Example 5-1 snmp Command Followed by the Tab Key

hostname:ONS15216 EDFA2> snmp
agent
attribute
host
mib
pdu
row
session
subtree
table

tree

Continue to enter a specific operation from the list until the complete command is created. (See Example 5-2.)

Use these commands to set up community strings ( Enabling SNMP Remote Management Community Strings) and traps ( cerent15216EdfaVersionGroup Table).

Enabling SNMP Remote Management Community Strings

SNMP communities are groupings of workstations and servers (or gateways) that can manage the ONS 15216 EDFA2. NMS's also 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:

• Creating a View

• Creating a Community Entry

The ONS 15216 EDFA2 has the two default community strings listed in Table 5-2.

Table 5-2 Default Community Strings

Community String
Default Privileges

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.

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 a Cisco Systems Engineer before modifying these settings.

Set View Entry

Command: snmp row set local cerent15216EdfaViewEntry
Syntax: snmp row set local cerent15216EdfaViewEntry view index # subtree
Description: 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. # 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

hostname:ONS15216 EDFA2> snmp row set local cerent15216EdfaViewEntry cerent

cerent15216EdfaViewMask '0'H

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 5-3 describes the command and MIB view prompts.

Creating a Community Entry

SNMP communities are groupings of workstations and servers (or gateways) that can manage the ONS 15216 EDFA2. NMS's 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 a Cisco Systems Engineer before modifying these settings.

Set CommunityEntry

Command: snmp row set local cerent15216EdfaCommunityEntry
Syntax: snmp row set local cerent15216EdfaCommunityEntry community index
Description: 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 5-4 for information concerning data for each prompt.

Example 5-4 cerent15216EdfaCommunityEntry Set Command

Loss of Output Power Alarm Setpoint

LpoutSetpoint

Command: snmp attribute get local cerent15216EdfaLpoutSetpoint
Syntax: snmp attribute get local cerent15216EdfaLpoutSetpoint
Description: This attribute notifies network operations personnel notification if the output power of the ONS 15216 EDFA2 drops below a level that impacts proper operation of the optical network.
Typically, network operations personnel should set the loss of output power alarm threshold at a value that is appropriate for the intended network application so that the alarm condition is meaningful. Consult with a Cisco Systems Engineer to determine threshold value for your application. As a guideline, Cisco recommends that loss of output power alarm threshold value be set at 1 dBm below the current output power level of the amplifier.
When the ONS 15216 EDFA2 is set to constant gain operation (factory default), the value for loss of output power alarm threshold cannot be changed. To display the loss of output power alarm threshold and other power and temperature alarm data, use the snmp table display local cerent15216EdfaCfgGroup command (shown in Example 5-12). This command returns the current alarm threshold default values.

LpoutDeviation

Command: snmp attribute get local cerent15216EdfaLpoutDeviation
Syntax: snmp attribute get local cerent15216EdfaLpoutDeviation
Description: This attribute is not required when operating in factory default, constant gain mode. Setting of the loss of output power alarm deviation is only necessary when the amplifier is used in constant output power.
This attribute is used to set the amount by which the output power must vary from the threshold setpoint 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 a Cisco Systems Engineer 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 dBm. The module triggers an alarm if it detects a signal level of 2 dBm below the current output power alarm level threshold value set for the amplifier.
When the ONS 15216 EDFA2 is set to constant gain operation (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 5-12. This command returns the current alarm threshold default values.
To set the loss of output power alarm deviation when the ONS 15216 EDFA2 is configured for operation in constant output power or constant pump power operation mode, type snmp attribute set local cerent15216EdfaLpoutDeviation at the command prompt followed by a number (as shown in Example 5-13). Valid entries are between 0 and 1000 and are in dBm times 100. For example, if the loss of output power deviation required were 0.2 dBm, the number input as the loss of output power alarm deviation would be 20.
The user is prompted to modify the attribute. If no changes are required, press Enter to return to command prompt.

Loss of Output Power Alarm Hysteresis

LpoutHysteresis

Command: snmp attribute get local cerent15216EdfaLpoutHysteresis
Syntax: snmp attribute get local cerent15216EdfaLpoutHysteresis
Description: This attribute is not required when operating in factory default, constant gain 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 Cisco Systems Engineer 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 dBm. The module clears the alarm if it detects a signal level of 0.2 dBm above the current output power alarm level threshold value set for the amplifier.
When ONS 15216 EDFA2 is set to constant gain operation (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 5-12. This command returns the current alarm threshold default values.
To set the loss of output power alarm hysteresis when Cisco ONS 15216 is configured for operation in constant output power or constant pump power operation mode, type snmp attribute set local cerent15216EdfaLpoutHysteresis at the command prompt followed by a number. Valid entries are between 0 and 1000 and are in dBm times 100. For example, if the loss of output power hysteresis required were 0.2 dBm, the number input as loss of output power alarm hysteresis would be 200.
The user is prompted to modify the attribute. If changes are not required, press Enter to return to command prompt.
