The Summaries tab (Network Explorer –> Summaries) lists routes, subnets, VLANs, Route Targets, HSRPs/VRRP groups, ports, NIOS grids, network views and VRFs (virtual routing and forwarding instances) in the network.
...
The Device Viewer is not limited to this information. Seven categories of detailed information are provided by the Device Viewer for the displayed network entity. For more, see Inspecting Devices in the Network.

Note: Reserved VLANs are not displayed. They are included in the API.
The Ports section lists ports found in the network. This table is a superset of all the ports listed in the Switch Port Manager page; if your license is active only for Switch Port Manager, the switch ports discovered and polled by NetMRI are the only ports listed here.
...
You can list all HSRP/VRRP Groups managed by NetMRI, or the HSRP/VRRP groups that are associated with a particular device group.
The HSRPs/VRRP Groups section lists Hot Standby Router Protocol (HSRP) groups and Virtual Router Redundancy Protocol (VRRP) groups found in the network, starting with the Virtual IP address of the group. Types are labeled in the Type column as HSRP or VRRP. The protocols are used for fault-tolerant
default gateway configuration across two or more devices in case the primary gateway router becomes inaccessible.
— To view details for an HSRP or VRRP: Click a group in the left panel. The corresponding viewer opens in a popup window. The devices participating in the group are listed in the viewer.

Summarizing Route Targets
Note: Click the View All Route Targets link to list all route targets in the center panel. Then apply a filter to isolate them for a device or a network view.
VRFs use route targets to specify how routes will be shared between different VRF networks. The typical format of a Route Target is two numeric values separated by colons, for example:
27000:100
The Route Targets summary in the left panel shows the list of Import and Export route targets that are defined in VRF-aware devices in the managed networks. The VRF RD (route distinguisher) values are listed in a separate column, and you can click on the link for each VRF's network view, which opens the Network Viewer window. This window also lists all devices forming the VRF network.
Selecting a route target causes the center panel to display all the instances where it is being used, along with details of the device and the VRF. This is helpful to understand how VRFs and particularly VRF-Lite are configured across the network.

Summarizing Network Views
To view the complete list of network views, click the View all Network Views link at the top of the list. You can list all network views containing networks managed by NetMRI, or the network views that are associated with a particular device group. Each network view listed in the left panel provides a link to the Network View window.
The Count value indicates the number of interfaces sharing the same network view. Each instance is differentiated by the interface name.
If you have a significant number of network views, you can apply a filter by clicking the Filters button at the top of the table, choosing the Network View option from the Select a New Field selector, and entering the name of the network view.
Network Views represent each network that is managed and monitored by NetMRI. For more information about network views and how to use and configure them, see Configuring Network Views and its subsections.

Summarizing VRFsAfter virtual routing and forwarding (VRF) networks are discovered and mapped to network views, you can use the VRFs summary to view the complete list of VRF instances throughout the managed network. You can sort the VRF information by any data column to see the relationships between VRF instances in virtual networks.
To view the complete list of VRF instances, click the View all VRFs link at the top of the list. By default, the VRFs are listed by VRF name. Data columns include the following:
VRF Name: displays the name of the VRF instance;
VRF Description: Displays a description if the VRF instance is configured with a description on the device;
Route Distinguisher: VRFs use route distinguishers to distinguish one set of routes (one VRF) from another. The route distinguisher is a unique number pre-pended to each route within a VRF to identify it as belonging to that particular VRF. The discovered route distinguisher value is listed here if a virtual network instance uses this value. (For related information, see Summarizing Route Targets.)
Device Name: the discovered name of the device hosting the VRF instance;
IP Address: The IP address of the managed VRF-hosting device. This value is a hotlink to the Device Viewer.
Network View: The network view of the managed VRF-hosting device. This value is a hotlink to the Network Viewer window.
VRF Network View: The network view to which the VRF is assigned. This value is a hotlink to the Network Viewer window. Note that this value may differ from the Network View identifier.
If you have a significant number of virtual routing and forwarding networks, you can apply a filter by clicking the Filters button at the top of the table, choosing the VRF Name option from the Select a New Field selector, and entering the name of the VRF. You can also filter by network view in the same way, or combine the two filters to isolate all VRF instances in a specific network view.
