CISCO Nexus

The Cisco Nexus switches are modular and fixed port network switches designed for data centers. This connector can be used to monitor such a device.

About

The connector uses an SNMP connection and DCF integration to monitor Cisco Nexus devices. This help page only applies from range 1.0.2.x onwards, except the section on the IGMP page, which was included in range 1.0.4.x.

Configuration

Connections

SNMP Main Connection

This connector uses a Simple Network Management Protocol (SNMP) connection and requires the following input during element creation:

SNMP CONNECTION:

  • IP address/host: The polling IP of the device.

SNMPv2 settings:

  • Port number: The port of the connected device, e.g., 161.
  • Get community string: The community string used when reading values from the device, e.g., public.
  • Set community string: The community string used when setting values on the device, e.g., private.

SNMPv3 settings:

  • Username: The SNMPv3 username.
  • Security level: The SNMPv3 security level.
  • Authentication type: The SNMPv3 authentication type.
  • Authentication password: The SNMPv3 authentication password.
  • Privacy type: The SNMPv3 privacy type.
  • Privacy password: The SNMPv3 privacy password.

External Components

From version 3.0.0.3 onwards, this connector uses an external DLL, Renci.SshNet.dll, to be able to communicate via SSH.

Usage

General

This page displays general information about the device, such as the Name, Location, CPU Usage, and Memory Usage.

It also contains the following buttons:

  • Reset Device: Resets the Cisco Nexus device.
  • Copy Configuration: Displays a page that allows you to generate a CISCO configuration copy.
  • ICMP: Displays a page with all ICMP statistics.
  • TCP/UDP Statistics: Displays a page with all TCP and UDP statistics.
  • System Services: Displays a page listing the state of the services of each OSI layer.

OpenConfig

Version 3.0.5.x of the connector introduces support for OpenConfig. You can update some columns from the Detailed Interface, Rx Interface, and Tx Interface tables.

When this is used, the data from SNMP will be removed in those tables and filled in with the values from OpenConfig.

To configure OpenConfig, fill in these parameters on the OpenConfig Settings page:

  • Data Source IP Address
  • Data Source Port
  • Data Source User Name
  • Data Source Password
  • Client Certificate (optional)
Note

OpenConfig should only be used with CISCO Nexus devices running version 10.2(7)/10.3(4) or higher. When OpenConfig is used in a DataMiner System with multiple Agents, you currently have to make sure you only have one Communication Gateway DxM active in the system (pending a fix to avoid that every Communication Gateway will make a connection).

Sensor

This page contains the Sensor table, which lists the type, scale, and the present value of each sensor.

System Health

This page contains the following tables:

  • Fan: Displays the operational status of all the fans.
  • Power Status: Lists the power-related administrative status and operational status of the manageable components in the system.

CLI

With the Command Line Interface (CLI), commands can be sent through SSH or via the NX API (from version 3.0.0.4 onwards).

This page contains the following parameters:

  • CLI Communication Type: Allows you to select either CLI (SSH) or NX API. Based on the selection, the CLI commands will be sent via SSH or via HTTPS.
  • User Name: The SSH user name.
  • Password: The SSH password.
  • NX API Version: Currently the version is by default set to 1.0. However, this could change after firmware updates.
  • Command Timeout Time: Allows you to set the maximum wait time (in milliseconds) for a command response.
  • Command Entries to Keep: Allows you to set the maximum number of rows visible in the Command History table.
  • Add Command: Adds a new command to be executed.
  • Command History: Table containing all the recently executed commands and their output.
  • Total Communication Issues: The total number of detected communication issues present in the Command History table.
  • Clear Command History: Clears the Command History table entries.

PTP

The Precision Time Protocol (PTP) pages display information regarding this functionality (from version 3.0.0.10 onwards). The PTP credentials must be filled in for this functionality to be activated.

This page contains the following subpages:

  • PTP Clock: Displays parameters regarding the clock.
  • PTP Interfaces: Displays the Foreign Master Records and PTP Interfaces tables.
  • PTP Grandmaster: Displays parameters related to the grandmaster clock.
  • PTP Time Sync: Displays parameters related to the time sync.

  • PTP Corrections: Displays the PTP Corrections table.

Interface Detailed

This page contains the Detailed Interface table. This table provides general information about each interface.

From version 1.0.3.7 onwards, the polling period of the Detailed Interface table (as well as the Interface Rx table and Interface Tx table) can be configured using the Detailed Interface Polling Interval parameter. The default value of this parameter is 2 minutes. Its possible values range between 30 seconds and 1 hour.

From version 3.0.3.1 onwards, you can add or delete VLANs from an interface via the right-click menu.

Interface Rx

This page contains the Interface Rx table. This contains the input statistics of each interface.

Interface Tx

This page contains the Interface Tx table. This contains the output statistics of each interface.

L2 L3 Interface

This page contains the L2 L3 Interface table. The table shows the administratively requested and actual operating configuration for switch port interfaces.

PoE

This page displays the PoE table. This table contains information about power Ethernet ports on a Powered Sourcing Equipment (PSE) device. Some settings can be configured in this table, such as the maximum amount of power that the PSE will make available for the power device.

BGP

This page displays the BGP Peer table. This table contains information about the connections with BGP peers. Some settings can be configured in this table, such as the time intervals for the ConnectRetry and KeepAlive timer.

Note

Because of rounding issues in the device itself, bit rates may be slightly inaccurate. Because of this, bandwidth utilization can exceed 100% without dropped bytes indication. Keep this in mind when configuring alarm templates.

The dynamic interfaces are created based on the number of rows in the tables 2800 Interfaces and 7400 VLANs (DCF Interfaces).

  • Interfaces_instance value_Interface Type: Dynamic interface with type inout.
  • VLANs_instance value_Interface Type: Dynamic interface with type inout.
