WISI Optopus

The WISI Optopus is an Optical Platform for FTTx and HFC. With this SNMP connector, you can control and monitor the parameters of the device.

About

With the WISI Optopus platform, any module can be mounted into any slot, so that fully customized individual configuration is possible, specific to the intended application.

Every card inserted into one of the 14 slots will generate its own individual Dynamic Virtual Element (DVE) when this option is enabled. In the DVE, you can configure parameters and alarm monitoring related to that card (Current Alarms, Alarm Log and Alarm configuration).

Note that two SNMP connections are established with the device. SnmpConnection2 has a different Set community string because some parameters require a different level of permissions, as stated in the MIB file.

From version 1.0.0.18 onwards, SSH communication with the device server can be done using RSA authentication. More details can be found in the documentation of new features of firmware version 2.1.0.0.

Configuration

Connections

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

SNMP Connection:

  • IP address/host: The polling IP of the device, e.g. 10.11.12.13.
  • Device address: Not used.

SNMP Settings:

  • Port number: The port of the connected device, by default 161.
  • Get community string: The community string in order to read from the device. The default value is public.
  • Set community string: The community string in order to set to the device. The default value is private.

SnmpConnection2:

  • IP address/host: The polling IP of the device, e.g. 10.11.12.13.
  • Device address: Not used.

SNMP Settings:

  • Port number: The port of the connected device, by default 161.
  • Get community string: The community string in order to read from the device. The default value is public.
  • Set community string: The community string in order to set to the device. The default value is Wisi.

Configuration of the SSH connection

When the element starts for the first time, all default values are set. In order to set passwordless communication between the element and the WISI device using RSA authentication, some steps must be taken. These only have to be done once.

A pair of keys must be provided to the WISI elements. By default they must be located under the folder C:\Skyline DataMiner\Documents\WISI Optopus\SFTP. To accomplish this, use the element's Documents folder in DataMiner Cube. Just add the keys using the Add document function. This will trigger the synchronization of the files throughout the cluster.

The key files should be created using Putty Key Generator. They must be of type RSA, using the Open SSH format and with 1040 bits (see "1" in the picture below). Save the public key from the panel by copying it to a file with the name provided in RSA Public Key File Name. Then export the private key to a file using the menu and save the file with the same name as RSA Private Key File Name (see "2" in the picture below). There is no need to set a Key passphrase.

Notes:

  • The first time the element connects to the WISI Optopus SSH server, an entry is added to the knownhosts.txt file created under the same folder mentioned above. It works as a proof that the element trusts the device's server.
  • Password authentication is only used while the connection is set up for the first time. After the new public key is uploaded and set, the SSH Authentication Methods parameter will be set to Only Public Key Auth. However, it is possible to revert to Key or Password authentication on the Security subpage of the Network page.

Usage

General

This page displays general information about the device:

  • Identification: Information about the network card.
  • Product Data: Information about the vendor and the device.
  • MIB II System Group: Information about the device.
  • General: Temperature, and buttons that are used to reset the device.
  • Time Settings: Time and date information.

Device

On this page, you can configure slots 15 to 22. They are related to the PS (Power Source), Fan Unit and SPF (Small form-factor Pluggable Transceiver) slots. Click the Rescan button to update the table with the latest inserted cards.

Network

This page displays parameters related to the headend network controller:

  • Interfaces Table: This table contains information about the device interfaces.
  • SFTP: Subpage where you can Upload and Download files towards the SFTP server incorporated on the device. Defaults values are filled in. To then update the firmware, use the Firmware page button.
  • TFTP: Subpage with TFTP configuration options.
  • Trap Receiver: Subpage where you can monitor and configure traps received from the device.
  • Firmware and Firmware Images: Subpages with information about the firmware images kept in the device's memory.
  • OH51 Email and OH51 Receiver: Only applicable for OH51 remote interface.

Network - IP

This page displays parameters related to the headend network controller IP.

Network - Other Protocols

This page displays parameters related to the headend network controller TCP, UDP and ICMP.

Slots

This page provides information about slots 1 to 14.

  • All Modules DVE Creation: Enables/disables DVE creation on all slots at once.

  • LX Slots Table:

  • LX Slots Device Type String: Allows you to set a virtual card. Set this to None to delete it. Every virtual card that has been set is displayed in the HE Passive Table, which you can reach via the Passive page button.

    • Module DVE Creation (Last column): Enables/disables DVE creation if a card is present in the slot.

  • Transmitters, Amplifiers, Receivers, Optical and Passive: There are different types of cards available for this platform, and the corresponding parameters can be viewed through these page buttons. There is an additional type, Passive, for slots with a virtual card.

Module Types

This page contains the tables that will generate the DVEs. If a DVE has been created, there will be a row in the table where that card type belongs.
