L1 Networking module
The Cable Networking module makes it possible to document the physical placement of the active passive elements of the network (i.e.: chassis, rack, patch panels, sockets), and the physical connections between the ports of active and passive devices (i.e.: patch cables). The Cable Networking Module consists of two sub-modules: Rack Module which can be used to document Racks and Rack-rows and the Socket Module which is to document sockets, the location of the sockets and the connection between them. The functions of the Rack module are required to use the functions of the Socket module properly.
With the Rack Module engine room level and floor level racks, rack raws and their placement can be added to the documentation. The illustrations of these racks on the diagrams are scaled and they show the exact placement of the cross patch panels and socket patch panels. The active and passive devices and the ports of them, the patch cables between the ports and the wall cables between the crosses are depicted in the same way.
With Socket module the placement of the sockets on the layout can be documented in an efficient way. Combined with the Host Networking module we can also document the location of the workstations discovered on the switch ports and we can track the changes.
The Cable Trace and Patch Management functions make the documentation of the L1 data as efficient as possible. We can add racks, rack-rows, cross patch-panels, we can connect the associated/linked ports, modify the labels of the patch panel ports and because of this modification the links between ports, we can add sockets in bulk and link them with the ports in rack – all this in only one step. The placement of the sockets is supported by a number of sorting functions which at the same time include socket labels so there is no need to spend time placing them. With the Cable Trace tool we can quickly track connected cables and the path of these cables can be looked at in a graphical and tabular form too. With the discovery of the L2 topology we can track and verify the cable segments of L2 connections one by one or all of them at the same time, or with adding patch cables we can add the connections that couldn’t be discovered. The Cable Trace system indicates automatically which cable section is used by which active connections so we can learn information
about the capacity and about the unused cable sections as well. The administration of the elements of the cable network can be done by the user on the GUI or by the manufacturer or its partners based on the available data or on-site as part of the service. With the Patch Management function you can administrate the patch cables on a graphical interface. The result of the documentation of the L1 and L2 is the whole physical and L2 logical topologies.
L2 / L3 Networking module
The L2 / L3 Networking module includes the mapping and creating the documentation of the routing/switching network devices on L2 and L3 logical topologies. The two technology modules can be purchased in one package or separately. The topological model is port and interface leveled in both cases.
Both modules are based on a detailed inventory of the routing / switching network devices. This inventory is collected by the data collector by detecting the devices automatically or there is the
possibility of adding the devices manually. The device inventory includes the hardware structure of the fixed and modular devices, their modules and optionally the sub-modules (eg.:sfp transciever).
By adding the modules of the devices, their ports and interfaces will be included in the system as well. Based on the description of the device the program will create a scaled preview of the devices which can be displayed on L2, L3, and L1 levels. The parameters of the ports and interfaces of the devices include their hardware and configuration features and these parameters will be automatically uploaded to the system after data collection.
The L2 Networking module includes the preparation of the L2 topology and the regular updates within the Update service. The L2 topology is a set of links that represent the LAN and WAN connections between the devices. The L2 topology is port and interface leveled. This means that the
L2 links will end at the corresponding ports and interfaces. The L2 links contain the characteristics of the L2 logical connections.
The L2 Networking module also includes the input of VLAN information from the configuration so the VLAN ID of the access ports and the list of the allowed VLANs for the 802.1q trunk port are automatically included in the documentation. This will allow you to search and filter the interfaces
and links in that VLAN.
The L3 Networking module includes the preparation of the L3 IP topology and the regular updates within the Update service. The L3 topology is a set of IP connections between the network devices, their ports and interfaces and the IP address ranges (subnet). The L3 topology is port and interface
leveled. This means that the L3 links will end at the corresponding ports or interfaces. The final result of the configuration process is an inventory of all the IP addresses and IP address ranges assigned to the network devices, including their most important features. These features can be displayed in
tabular form or graphically.
vrf / VPN modul
With the vrf / VPN module we can create a model in VPN context of the overlapping IP address ranges of MPLS VPN networks of large companies and telecom service providers.
The Netopgraf system by interpreting the configuration of the network devices can build up not only the L2 and L3 topologies but also assigns the IP addresses and address ranges of the PE and CE devices to the corresponding vrf / VPN with the knowledge of L2 topology and IP routing.
With the help of this integrated system the following aspects of a given Ipv4 network will be available:
- the address of the Ipv4 network,
- VPN classification,
- RD number,
- VLAN indentification,
- type of the L2 network,
- all the IP addresses assigned to the address range.
The vrf/VPN module is a complementary module of the L2 and L3 Networking module. This module is required to assign vrf / VPNs to IP addresses in the case of vrf/VPN technology.
When using this module it is recommended to use unique vrf names in the network.
This integrated representation of L2, VLAN, L3 and vrf / VPN topologies and the assignment of IP addresses and interfaces to the right vrf / VPN domains is a unique solution provided by the Netopgraf system.
Security Networking module
The Security module includes the mapping and documentation of the network security devices on L2 and L3 logical topologies. The topological views are port and interface leveled. The network security devices are added into the L2 and L3 topologies in a similar form as the routers because firewalls at L2 and L3 have a similar function.
The collection of the data and the loading of data into the system will vary depending on the manufacturer of the device and on the security settings therefore some information has to be made available to the service provider by prior arrangement.
Network security devices are classified to two groups:
- target hardware devices
- server based devices
We garatuee the technical support by developing the needed support system for any server or hardware based device if the manufacturer is specified.
Supported hardware based security devices: Cisco PIX, ASA, FWSM, ACE, F5, Nokia Checkpoint.
Host Networking modul
The Host Networking module includes the discovery of IP servers and workstations and their placement in L2 and L3 logical topology.
The purpose of the Host Networking module is to collect the IP nodes connected to network devices and to collect the key parameters of these nodes which are:
- MAC address, manufacturer based on OUI,
- IP address (netmask)
- L2 connection point – i.e.: connected switch port,
- L3 connection point – i.e.: connected IP address range (subnet, vrf/VPN)
As part of the Host Networking service we discover the servers, the virtual servers, the workstations and other IP nodes as well (eg.: printer, UPS). On request these nodes are distinguished by name convention, IP address and manufacturer. Based on the distinction we can handle the categories separately within the service.
The criteria of the discovery and addition of the IP hosts is the regular updates of the network devices. These updates take place within the L2 and L3 Networking Update service. The Host Networking module is not intended to fully detect the hardware configuration and software configuration of IP hosts.
With the L1 Rack module and L1 Socket module and with the administration of the patch cables the IP nodes on the sockets will be easy to track down. In case of using the vrf/VPN module it can be found out which VPN network the Host is working on.
Optical Networking module
The Optical Networking module includes the placement in L1, L2 and L3 logical topologies of the DWDM and CWDM optical network devices. The topology model is port and interface leveled. The module is based on a detailed inventory of the optical network devices which is automatically collected by the data collector from all devices after discovery or manual recording. The device inventory includes the hardware architecture of the fixed and modular devices, their modules and in specific cases the sub-modules. By adding the modules of the devices the system also add the ports and interfaces and with its own device descriptions creates the scaled pictures of the devices which can be displayed on L1, L2 and L3.
L1 links between optical and other devices (such as switches) can be administered in the system or can be loaded into the system from other sources in an agreed format.
IP Phone modul
The IP Phone module includes the discovery of the IP Phones working on t he network and their placement in t he L2 and L3 logical topologies. The configuration data of the IP Phones are completed with phone extention details (such as: additional number, display name, permission, pickup group), this way all important information can be found in one place.
With this module we can make a full inventory of the IP Phones working on t he network and besides that the spared telephones on stock can be administrated as well. The L2 connections of the phones can be detected with cdp and lldp protocol.
In case of documenting the endpoints of the cable network and administrating the patch cables the location of the phones can be tracked.
The Wireless module includes the discovery of Wireless Access Points and Controllers working on the network and their placement in L2 and L3 logical topologies. The system also stores the inventory and configuration data of wireless devices.
With this module we can create a complete inventory of the Access Points in the network, and the L2 connections of these AccessPoints can be detected by using cdp and lldp protocols. By documenting the endpoints of the cable network and administrating the patch cables the physical location of the AccessPoints will be included in the documentation.
