Default network view nodes

Use this information to understand which nodes appear by default in your network view tree.

Default nodes in the network view tree

By default, the network view tree contains a separate IP network view hierarchy per domain for each network technology; you will see an IP network view hierarchy only for each domain.

Optionally you can add an LTE network view hierarchy for each domain. Do this by creating a template-based dynamic view using the lte_default network view template..

You might see only some of the default network view libraries. The nodes that appear in your network view tree vary depending on the types of devices in your network, on the technologies used in your network, and on how the network views have been configured. Access to network view libraries can also be restricted by the administrator for users, roles, or groups. If you have more than one network domain, then you might see one network view hierarchy for each domain, each hierarchy containing some or all of these network view nodes.

Note: Default network views that are based on alert severity are filtered such that they contain only devices that have one or more alerts of that severity. For example, the Alert Views > Acknowledged Alerts > Major view contains devices that have one or more Major alerts. However, those devices can also have alerts of other severities. For example, the Major view could contain device A, on which there is a Major alert and a Critical alert. All alerts on the device are included in that network view. All alerts on the device are shown when you use the Show Events tool. It is possible to edit the filters for the network views to include only devices that have a certain alert severity and no other alert severities. However, take care that devices that have multiple alerts with different severities are not accidentally omitted from your network view hierarchy.

Default network view nodes: IP network

The following table lists the default network view hierarchy for IP network devices.

Table 1. Default network view nodes: IP network
Network view node	Description of devices contained in this network views node
Alert Views > Acknowledged Alerts	Devices with associated acknowledged alerts. The network views are organized by severity of the alert.
Alert Views > Acknowledged Alerts > Critical	Devices that currently have acknowledged alerts of critical severity associated with them.
Alert Views > Acknowledged Alerts > Major	Devices that currently have acknowledged alerts of major severity associated with them.
Alert Views > Acknowledged Alerts > Minor	Devices that currently have acknowledged alerts of minor severity associated with them.
Alert Views > Critical Ping Fail Events at least an hour old	Devices that have any ping fail events that are at least one hour old and have a Severity of 5 (critical).
Alert Views > PingFailRootCause	Devices which have associated ping fail alerts and where the alert is a root cause alert.
Alert Views > SNMP Poll Fail	Devices that currently have SNMP fail (NmosSnmpPollFail) events associated with them. These devices have SNMP polls configured to run on them, but are unreachable using SNMP. If the devices are not SNMP-enabled, they should not have SNMP polls configured to run on them. If the devices are SNMP-enabled, an SNMP poll fail might indicate a fault on the device.
Alert Views > SnmpLinkInDiscards	Devices with alerts of type NmosSnmpLinkInDiscards.
Alert Views > Unacknowledged Alerts	Devices with associated unacknowledged alerts. The network views are organized by severity of the alert.
Alert Views > Unacknowledged Alerts > Critical	Devices that currently have unacknowledged alerts of critical severity associated with them.
Alert Views > Unacknowledged Alerts > Major	Devices that currently have unacknowledged alerts of major severity associated with them.
Alert Views > Unacknowledged Alerts > Minor	Devices that currently have unacknowledged alerts of minor severity associated with them.
All Management Systems	All EMSs (Element Management Systems) that Network Manager has discovered. Each EMS network view displays the managed elements managed by that EMS, together with the connectivity between the managed elements.
All Routers	All devices with layer 3 connectivity, that is, all devices that Network Manager has classed as routers in the ncim.entityClass database table.
All Switches	All devices with layer 2 connectivity, that is, all devices that Network Manager has classed as switches in the ncim.entityClass database table.
BGP Networks	Devices grouped by membership of BGP networks.
Custom view	A custom collection of devices. You can add any devices or device collections to the custom view.
Device Classes	Devices grouped by the Network Manager device class hierarchy. Examples of device classes include Cisco and Juniper.
Discovered ASMs	An ASM agent running on a device corresponds to a commercial server or database product running on that device. These network views group devices within a network based on the commercial server or database products running on those devices.
HSRP Groups	All the Hot Standby Routing Protocol (HSRP) groups in the network domain.
IGMP Groups	All the discovered Internet Group Membership Protocol groups.
Manually Added Devices	An automatic collection of all devices that have been manually added to the topology. If a device is not discovered, you can add it to the topology manually. All devices that were added manually appear in this view.
Monitoring Views > Devices that have at least one interface event for HighDiscardRate	Shows devices that have interfaces that have a high rate of discarded packets.
Monitoring Views > Initial Ping Fail Events	Shows devices that have failed ping polls.
MPLS > MPLS Core	Shows the Multiprotocol Label Switching Path (MPLS) core network.
MPLS > MPLS VPNs	The MPLS Virtual Private Networks (VPNs) within your network domain.
MPLS TE	MPLS Traffic Engineering (TE) tunnels within your network domain.
Multicast Routing MDTs	Shows any discovered Multicast Distribution Trees (MDTs).
NAT Address Spaces	Devices grouped by membership of Network Address Translation (NAT) address spaces.
Network Probes	Shows one subview for each probe type. The subviews hold devices that are configured as probe sources or targets.
OSPF Routing Domains	Devices grouped by membership of Open Shortest Path First (OSPF) areas and routing domains.
PIM network	Devices grouped by membership of Protocol Independent Multicast (PIM) networks.
SLA > Network Probes > IPSLA	Contains network views collecting probes of a certain type. For example, DHCP, DNS, echo, and so on. Also contains a view of all probes.
Subnets	Devices grouped by membership of IPv4 and IPv6 subnets.
Unassigned view	All devices in a domain that are not currently assigned to a network view. The view is updated dynamically as devices are added and removed from views in the domain.
VLAN Ports	All the Virtual Local Area Network (VLAN) ports in the network domain organized by VLAN identifier or by VLAN name. Note: The Global VLANs network view does not appear by default. However, you can create a Global VLANs network view manually.
VPLS > MPLS Core	Shows Virtual Private Label Switching paths through the MPLS core.
VPLS > VPLS VPNs	Shows Virtual Private Label Switching Virtual Private Networks.
VTP Domains	Devices grouped by membership of VLAN Trunking Protocol (VTP) domains.

Default network view nodes: LTE network

The following table lists the default network view hierarchy for LTE network devices.

Table 2. Default network view nodes: LTE network
Network view node	Description of devices contained in this node
LTE Network Drilldown	Lists all the LTE network views available for listing out devices. All network views in this node are in tabular mode by default.
LTE Network Drilldown > E-UTRAN	Lists all eNodeB devices in the evolved UMTS Terrestrial Radio Access network (EUTRAN).
