Devices Discovery

Discovering a Device

Procedure

Use this procedure to discover a new device.

In order to control and manage devices, you have to let the proNX Optical Director know which devices you want to control and manage. This is called device discovery, and is typically the first step you perform when using the proNX Optical Director. You can discover one device at a time or, more typically, you can discover multiple devices based on your discovery selection criteria. As part of device discovery, you will assign the device to a site. This allows the proNX Optical Director to accurately place the discovered device on the map.

  1. Start from the Devices Configuration page.
  2. If you want to discover a new device for an existing site, categorize the device tree by site and select the site.
  3. Click Discovery and select Device Discovery from the drop-down list.

    The Device Discovery dialog appears.

  4. Specify the IP address or IP address pattern in the Address Pattern box.

    You can enter a single IP address or an IP address pattern representing multiple IP addresses. See Table 45.

    Table 45: Address Pattern

    Address Pattern

    Example

    Full IPv4 or IPv6 address

    10.228.103.4

    List of IPv4 or IPv6 addresses separated by commas

    10.228.103.4, 10.228.145.8

    A range of IPv4 or IPv6 addresses

    10.228.103.1-10

    All IPv4 or IPv6 addresses in a subnet

    10.228.103.255

  5. Specify the NETCONF Username and NETCONF Password. These are the read-write login credentials for the device.

    If you are discovering multiple devices, you must ensure that the login credentials are the same across the devices you want to discover. If the login credentials are not the same, then you will have to limit each discovery to the group of devices that share the same login credentials.

    The user that you specify must have read-write privileges for all attributes on the device. Devices are shipped with a default read-write username and password that you can use to log in for the first time. For information on the default username and password for a device, see the respective device documentation. Specifically, for the TCX1000-RDM20, see the TCX1000 Programmable ROADM Hardware Guide. For the TCX1000-ILA, see the TCX1000 Inline Amplifier Hardware Guide.

  6. Specify the site.
    • If you selected the site in step 2, then the Site Name, Latitude, and Longitude are automatically populated. You can proceed to step 13.

    • If you did not select the site earlier, then proceed to step 7

  7. Click Select Site.

    The Create or Select a Site window depicting a map of the world appears.

  8. To pan around the map, click and hold anywhere in the map background and drag the map until the desired part of the map comes into view.
  9. To zoom in and out:

    To zoom in, click the in the lower right corner. Alternatively, you can zoom in by using your mouse scroll wheel.

    To zoom out, click the in the lower right corner. Alternatively, you can zoom out by using your mouse scroll wheel.

    Note If you zoom out such that two or more sites are on top of each other, a single icon is displayed. To see the sites represented by the icon, click the icon.

  10. If you want to create a new site, click the location on the map where you want to create the new site. Zoom in to get better resolution.

    The New Site dialog appears. Type the Site Name of the new site and click Save.

    The site appears on the map.

  11. Click the site in which you want to add the new device and click Select.

    The Create or Select a Site window closes and the selected site is populated in the Site Name, Latitude, and Longitude boxes.

  12. Optionally, set the Physical Location. The location is set using the location tree for the site. The location tree provides a structured way for you to place a device at a location within a site.
    • To specify the Physical Location of the new device, click Select. This brings up the Select Location dialog.

    • If you want to edit the tree to create a new building, room, or rack, see Editing a Location Tree.

    • Select the rack where you want to place the device and click Select. The Select Location dialog closes.

    Your selection is now shown in the Physical Location field.

  13. Click show in Advanced Settings to see additional configuration parameters.

    Parameter

    Description

    Automatically Configure JUNOS

    If the device to be discovered is a Juniper Networks router or switch, select yes to automatically configure that router or switch for NETCONF and SNMP access from the proNX Optical Director. This feature requires Telnet access to be enabled on the router or switch.

    When selected, the proNX Optical Director configures the router or switch as follows:

    • enables the router or switch to accept NETCONF requests destined for the port you specify in NETCONF Port

    • creates an SNMP read-only community called "public" if it doesn’t already exist

    • creates an SNMP read/write community that you specify in SNMP Community

    SNMP Community

    Specify the SNMP read/write community string used by the proNX Optical Director to write to the device. By default, the proNX Optical Director uses the "private" community string.

    You do not need to configure SNMP when discovering TCX1000-RDM20 devices.

    SNMP Port

    Specify the SNMP port to use for SNMP requests to the device. By default, the proNX Optical Director uses the standard port 161.

    You do not need to configure SNMP when discovering TCX1000-RDM20 devices.

    NETCONF Port

    Specify the NETCONF port to use for NETCONF requests to the device. By default, the proNX Optical Director uses the standard port 830, which is the default used by many Juniper Networks devices including the TCX1000-RDM20.

    Note: The BTI7800 Series device uses a different NETCONF port number. See the BTI7800 Series Software Configuraiton Guide for more information.

  14. Click Discover to start the discovery task. To monitor the progress of this task, see Viewing the Tasks List.

Rediscovering a Device

Procedure

Use this procedure to rediscover a device or multiple devices.

Rediscovering a device causes the proNX Optical Director to refresh its view by performing a full data retrieval from the device. You do not normally need to rediscover a device because the proNX Optical Director regularly synchronizes with all devices under management. However, if you suspect the proNX Optical Director has a stale view of a device, you can rediscover it to speed up the synchronization.

  1. You can rediscover a single device, multiple devices, or all devices at a site.
    • To select all devices at a site, start from the Devices Configuration page, categorize the device tree by site, and click the site that you want to rediscover.

    • To select a single device, start from the Devices Configuration page, expand the device tree to see the list of devices, and click the device that you want to rediscover.

    • To select multiple devices, once you select a single device or site, use the Ctrl key (Cmd key in Mac OS X) to multi-select other devices or sites. You can select a combination of sites, a combination of devices, or a combination of sites and devices.

  2. Once you have selected the devices you want to rediscover, click Discovery>Re-discover Selected. To monitor the progress of this task, see Viewing the Tasks List.

Undiscovering a Device

Procedure

Use this procedure to undiscover a device or multiple devices.

Undiscovering a device removes the device from proNX Optical Director management. The proNX Optical Director deregisters itself from the device and removes the device from view.

  1. You can undiscover a single device, multiple devices, or all devices at a site.
    • To select all devices at a site, start from the Devices Configuration page, categorize the device tree by site, and click the site that you want to undiscover.

    • To select a single device, start from the Devices Configuration page, expand the device tree to see the list of devices, and click the device that you want to undiscover.

    • To select multiple devices, once you select a single device or site, use the Ctrl key (Cmd key in Mac OS X) to multi-select other devices or sites. You can select a combination of sites, a combination of devices, or a combination of sites and devices.

  2. Once you have selected the devices you want to undiscover, click Discovery>Un-discover Selected.

    When you undiscover a device, it is normal to see transient error notifications as the proNX Optical Director receives messages from the device that has been undiscovered. These messages will stop once the undiscovery is complete.

Resynchronizing the Network

Procedure

Use this procedure to resynchronize the proNX Optical Director with all devices in the network.

Resynchronizing with the network causes the proNX Optical Director to rediscover all devices under management. You do not normally need to resynchronize with the network because the proNX Optical Director regularly synchronizes with all devices under management. However, if you suspect the proNX Optical Director has a stale view of many devices in the network, you can use this procedure to speed up the synchronization.

  1. Start from the Devices Configuration page.
  2. To resynchronize the proNX Optical Director with all devices in the network, click Discovery>Resync Network.

    To monitor the progress of this task, see Viewing the Tasks List.

Moving a Discovered Device to a Different Site

Procedure

Use this procedure to move a discovered device to a different site. You normally specify the site when you discover a device, but if you specified the wrong site or if you simply want to change the site that the device was originally associated with, then you can use this procedure to do that.

  1. You can move a single device, multiple devices, or all devices at a site.
    • To move all devices at a site, start from the Devices Configuration page, categorize the device tree by site, and click the site that you want to move.

    • To move a single device, start from the Devices Configuration page, expand the device tree to see the list of devices, and click the device that you want to move.

    • To move multiple devices, once you select a single device or site, use the Ctrl key (Cmd key in Mac OS X) to multi-select other devices or sites. You can select a combination of sites, a combination of devices, or a combination of sites and devices.

  2. Once you have selected the devices you want to move, click Discovery>Move Selected to Site.

    The Move Selected to Site window appears.

  3. From the Site drop-down list, select the site where you want to move the selected devices.
  4. Optionally, set the Physical Location for the device at the new site. The location is set using the location tree for the site. The location tree provides a structured way for you to place a device at a location within a site.
    • To specify the Physical Location of the new device, click Select. This brings up the Select Location dialog.

    • If you want to edit the tree to create a new building, room, or rack, see Editing a Location Tree.

    • Select the rack where you want to place the device and click Select. The Select Location dialog closes.
