Features

TeemIp cable management allows you to document the cable layouts of your organization. Connect physical interfaces to wall mounted network sockets, to patch panels hosted in racks or to other physical interfaces, document your patch cables and your underlying cabling layout, manage your cross connects: the extension enables a large scope of connection scenarios as the following drawing highlights:

Furthermore, the extension displays the wiring that links devices, physical interfaces and network sockets together, like:

Note that the drawing has been manually rearranged.

Limitations

There is no specific limitations with that extension.

Requirements

TeemIp standalone: The extension is embedded in TeemIp standalone, starting with TeemIp 3.1.

iTop: When installed on an iTop application, you need IPAM for iTop to be installed as well.

In both case, make sure that Datacenter Management has been selected at installation time.

Installation

TeemIp standalone: Installation is done with the application itself, through the setup.

iTop: To add the extension on an iTop application, follow the Standard installation process.

Configuration

No specific configuration is required in TeemIp's configuration file or in IP configs for that extension to work. However, some default settings may be changed:

Configuration file

Under the Modules specific settings section, default parameters used by the Find wiring action on Cross Connects may be overwritten by the following configuration lines.

	'teemip-cable-mgmt' => array (
		'find_wiring_paths' => array (
		  'max_rack_levels_to_cross' => 5,
		  'max_offers_to_display' => 32,
		),
	),

Global IP Settings

Under the Other Settings fieldset, the Allow cabling toward another organizations parameter enables patch panels from a given organization to be connected to patch panels of other organizations.

Patch Panel

As everyone knows, a patch panel is a piece of hardware with multiple ports that helps organize a group of cables. Each of these ports contains a wire that goes to a different location and can be set for fiber optic cables, cat5 cables, RJ45 cables, and many others. That class allows you to register them in TeemIp's CMDB.

Displaying a Patch Panel

In the Network dashboard that is accessible from a submenu of the standard CMDB overview menu, find the Patch Panel dashlet, click on it and select the item you are interested in:

With the extension Datacenter View Extended, Patch Panel display will look like:

Creating network sockets

If the capacity is set, to value c for instance, TeemIP will offer to automatically create c network sockets and to attach them to the patch panel. If n network sockets do already exist, with n < c, then the menu will still be displayed but only (c - n) network sockets will be created. When created, network socket will be set to inactive mode and will inherit of attributes location, rack, patch panel (obviously) and interface connector (if exists) from the patch panel.

Creating back end network cables

If some network sockets are already attached to the patch panel, TeemIP will offer to automatically connect the back end interface of these network sockets to remote sockets located in another patch panel of another Rack. This action removes to TeemIP administrator the burden of creating back end network cables for each of the network sockets attached to a patch panel.

When action is launched, TeemIP offers first to select the remote patch panel…

.. before creting the links in accordance with the number of available sockets in the remote rack.

By default, the remote patch panel must belong to the same organization as the source one. This behaviour may be changed through the parameter Allow cabling toward another organizations of the Global IP setting of the source organization, as described here.

Network Socket

A network socket is the passive physical piece of hardware where you plug a network cable to establish a link between different network devices.

Tabs

Tab Description
Cables All cables connected to the network socket
A network socket can be installed in a patch panel or as a stand alone equipment in a room.
  • When installed in a patch panel, attributes Location, Rack and Patch panel are mandatory.
  • When standing alone, attribute Location is mandatory but Rack and Patch panel must NOT be set.

Displaying a Network Socket

In the Network dashboard that is accessible from a submenu of the standard CMDB overview menu, find the Network Socket dashlet, click on it and select the item you are interested in or select it directly from the Patch panel detailed display :

Network Sockets have 2 sides:

  • A front end where RJ45 cables or optical fibers are plugged in,
  • A back end that links the socket to another network socket.
A few rules are enforced at front and back ends' levels.
  • On the front end side,
    • A network socket cannot be connected to both a remote network socket and a connectable CI.
    • A network socket may belong to a Cross Connect and may be connected to a remote network socket at the same time.
  • The front end network socket and the back end one cannot be the same.

Attribute Status is read only and automatically computed:

  • If no back end network socket is set, status is set to Inactive,
  • If a back end network socket is set but if no physical interface nor network socket is set, status is set to Ready,
  • If a Cross Connect is set and if it is Active, status is set to Active
  • If a back end network socket is set and if a physical interface or a network socket is set, status is set to Active.

In other words:

Front End Information Back End Information Status
Physical interface Network socket Cross connect Back end network socket
* * * unset Inactive
unset * set and active set Active
unset set * set Active
set unset unset set Active
All other cases set Ready

Attribute Cross Connect, is set or unset from the Cross Connect objet, at the time where the Network Socket is attached to the Cross Connect, as part of the local or peer unit information. See below

Network sockets implements three 1:1 relations. As the datamodel doesn't provide such attributes by default, these 1:1 relations are automatically computed when objects are created, modified or deleted: when one side of the relation is changed, the other sides (new and old when appropriate) are changed. These relations are:

  • 1:1 relation between the physical interface of a CI and the network socket attribute of the interface,
  • 1:1 relation between the network socket and a remote network socket,
  • 1:1 relation between the network socket and a back end one.

Cross Connect

A cross connect represents the cabling necessary to establish a direct link between two separate organizations in a data center, thus allowing the establishment of a private network link and eliminating the need to connect them using the internet.

Displaying a Cross Connect

In the Network dashboard that is accessible from a submenu of the standard CMDB overview menu, find the Cross Connect dashlet, click on it and select the item you are interested in :

Finding Wiring Paths

A cross connect documents a link between one or two network socket hosted in a patch panel sitting in a rack of a given organization and one or two peer network socket hosted in a peer patch panel sitting in a peer rak of a peer organization. The Find wiring paths action will display all the available cabling paths that may be establish to connect 2 network sockets that answer to the previous conditions.

Network admin may select one of the offered path and manually create it within TeemIP.

The Find wiring paths action doesn't scan the entire CMDB. By default:
  • The number of racks that the paths may cross is limited to 5,
  • The maximum of offers or proposals made by the tool is set to 32.

These value can be overwritten through the configuration file, as described here.

Physical Interface

TeemIp Cable management extension alters Physical interfaces with new attributes that allow connections to a network socket or to the interface of another connectable CI.

Physical Interface Properties

Name Type Mandatory?

Remote physical interface Foreign key to a(n) PhysicalInterface No
A physical interface cannot be connected to both a network socket and another physical interface.

These 2 relations brought by the extension implement 1:1 relations. As the datamodel doesn't provide such attributes by default, these 1:1 relations are automatically computed when objects are created, modified or deleted: when one side of the relation is changed, the other sides (new and old when appropriate) are changed. These relations are:

  • 1:1 relation between the physical interface and the network socket attribute of the interface,
  • 1:1 relation between the physical interface and another physical interface.

A connection between a physical interface and a network socket will look as follows.

A connection between two physical interfaces will look as follows.
