Icons in Topology Views

Icons that appear in OneClick topology views are graphical representations of network entities. Some network entities include:
  • Individual devices
  • Groups of devices
  • Geographic locations
  • Physical connections
An icon is simply the image with which you interact when you manipulate and configure a modeled element. When monitoring the condition of your network, an icon represents the current status of a device, network group, device location, or a physical link.
 
DX NetOps Spectrum
 offers both aggregate
 
and individual
 
icons for representing entities in your infrastructure.
Aggregate Icons
An IP or physical address does not manage an aggregate icon. However, you can configure aggregate icons to display the device IP address that a container represents. Or, you can configure them to display the subnet address of the devices that the container represents. Aggregate icons primarily act as containers, or placeholders, in a topology view.
An aggregate icon often represents a network group. Some examples of network groups are LAN, LAN_802.x, FDDI, ATM_Network, WA_Link, and Dialup_Link. The following image is an example of an aggregate icon:
 spec--aggregateicon_SCR 
 
DX NetOps Spectrum
 offers many types of aggregate icons. The appearance of an aggregate icon is always based on the entity it represents in your network.
Individual Icons
Individual icons are typically associated with an IP address or a physical address. 
DX NetOps Spectrum
 can communicate directly with the devices the individual icons represent, so long as the entities they represent are SNMP and ICMP entities.
Individual icons often represent network devices. Some examples of individual icons are those icons that represent a router, switch, or host. The following image is an example of an individual icon:
 spec--individualicon_SCR 
 
DX NetOps Spectrum
 offers many types of individual icons. The appearance of an individual icon is always based on the entity it represents in your network.
Icon Types by Device model category
You model devices in your network through Discovery or manual modeling. During modeling, 
DX NetOps Spectrum
 automatically determines the functionality of each device and selects the appropriate icon shape and symbol for that device.
Icons come in various shapes and sizes. Icon symbols vary by the model class that is represented and by the topology in which the icon is located.
Icon types include:
  • VNM icon
  • Network group icon
  • Device icon
  • Off-page reference icon
  • Segment icon
  • Live pipes (links)
VNM
The Virtual Network Machine (VNM) icon typically appears in the top-level view above the network group icons. The background color of the VNM icon changes to indicate the current condition of the 
SpectroSERVER
. For example, the VNM icon turns red when 
SpectroSERVER
 disk space reaches 90 percent capacity.
 spec--vnmoneclick_SCR 
Network Group Icon
The network group icons represent network groupings, for example, cable groups, LANs, and IP Class A, B, C networks. The following icon shows an example of a LAN network group icon:
 spec--networkgroup_oneclick_SCR 
 
Device Icon
A device icon represents an individual device. The device icon color changes to indicate the current condition of the modeled device. For example, the device icon changes to red whenever 
DX NetOps Spectrum
 detects a serious condition requiring attention. The following icon shows an example of a device icon:
 spec--device_oneclickicon_SCR 
 
Off-Page Reference Icon
The off-page reference icon is a special purpose topology icon. The off-page reference icon represents a device that is directly connected to a device in the current view but which is modeled in another layer. The following icon shows an example of an off-page reference icon:
 spec--offpage_reference_ICO 
 You can globally suppress off-page references in topology views. For more information about suppressing off-page references, see .
Segment Icon
Segment icons represent conceptual elements of a network. Examples of segment icons can include a coax segment, a wa_segment, a fanout, an unplaced icon, and a pingable. The following icon shows an example of a segment icon:
 spec--segment_onelick_ICO 
Live pipes represent the connection status between network devices. The links change color to indicate the current condition. A gold pipe represents a resolved connection or indicates that live pipes have not been enabled for the connection. A silver pipe represents an unresolved connection.
Live pipes are not enabled by default. To monitor the connection status between devices, enable a live pipe. The following image shows an example of a live pipe which has been enabled:
 spec--enabledlivepipe_SCR 
Icon Color and Condition
All icons change color to indicate the condition of the device or devices they represent. For instance, a device icon changes color when an alarm condition for that device occurs. A rollup triangle on a device icon or container icon changes color when an alarm condition occurs on one or more of its components. The components include devices or interfaces.
Rollup Condition Colors
The rollup triangle that is associated with the network container icon indicates that one or more components of the container has an alarm condition. In this example, a device within the network container has a critical alarm.
 spec--rolluptriangle1_SCR 
The rollup triangle that is associated with the device icon indicates that a component of that device has an alarm condition. In this example, an interface on a Cisco router has a minor alarm.
 spec--rolluptriangle2_SCR 
Icon Condition Colors
 spec--iconconditioncolors_OTH 
Logical links (or pipes) change color to indicate the condition of the connection:
  • Disabled or maintenance conditions = brown
  • Good conditions = green
  • Initial conditions = blue
  • Suppressed or unknown conditions = silver
  • Poor conditions = red
Proxy Models
To easily identify proxy models in a topology view you will see a PROXY text watermark show up overlaid over the model icon. You can see various types of highlighted Proxy Models below:

Do the following to enable or disable this view:
 
  • You need to select the relevant model and set the 
    "Is a Proxy Model" 
    attribute to 
    Yes
    , to enable the view.
  • You can also set the 
    "Is a Proxy Model"
     attribute to 
    No
    , to disable the view.
 You can use
 Attribute Editor
 to set the 
"Is a Proxy Model"
 attribute by editing the 
isEventCreationEnabled (0x129f8)
 attribute.
The 
isEventCreationEnabled (0x129f8)
 attribute= 
false
 only indicates that the model is a proxy model and nothing more.
Wireless Network Devices
Wireless Devices models in the Topology View has the Wireless sign on the icon to distinguish them from non-wireless device models.
The icon colors of wireless device models will depend on the state or Icon condition as explained in the Icon Condition Colors above.

Topology View using new Accessibility Icon theme
To provide a better user experience and in adherence to VPAT/508 standards, we have enabled an Accessibility theme for the OneClick topology view.
This theme provides new indicators denoting model severity/icon conditions on top of our existing topology view. This will enable model severity view, which is currently color coded, for users who are unable to distinguish between colors.
The accessibility icons will have additional indicators so that users can easily identify the difference in the icon model's severity. 
The OneClick Console has two icon themes, Accessibility and OneClick. By default, the OneClick icon theme is selected.
 
To enable the Accessibility theme, follow these steps:
 
  1. Click 
    Start Console
     from the OneClick Administration page.
    The OneClick Console user interface is launched. 
  2. Navigate to the menu options, 
    View
     > 
    Icons Theme
    , and then select 
    Accessibility
    .
    The OneClick Console automatically refreshes and the Accessibility indicators are displayed in the topology view.
The Icons theme selection is persistent across sessions. Once you have selected an icon theme for your topology, you will view the same theme in the OneClick console every time you logon.

To revert to the (default) OneClick icon theme, follow these steps:
 
  1. Navigate to the 
    OneClick Console
     menu options, 
    View
     > 
    Icons Theme
    , and then select 
    OneClick.
              The OneClick Console automatically refreshes and the default theme is displayed in the topology view.
