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.
CA 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
CA 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.
CA 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
CA 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 Theme
You model devices in your network through Discovery or manual modeling. During modeling,
CA 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.

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
CA 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
