IP Address Management Module

About

IP Address Management module provides an easy way to manage IP address pools and subntes in the system. It also enables the creation of VLAN groups as well as single public and private VLANs. The module does not operate on the physical layer of network devices therefore it shall be used only to handle pools, subnets and VLANs in a more efficient manner.

Tree

ED_ipam1.png

All IP pools and subnets are grouped into a tree. After clicking on a given subnet, its summary is displayed on the right side along with the boxes that present devices and VLANs assigned to this subnet. The ‘Create New Subnet’ can be used in order to add a new parent subnet to the tree. Fill out the form as follows:

  • IP Type: the type of a subnet, eitherIPv4 or IPv6
  • Subnet: the address of a subnet, e.g. 192.168.1.0 for IPv4 or 2001:db8:: for IPv6
  • Mask: the mask of a subnet in numerical form, e.g. 24
  • Status: a subnet can be set as Available, Active, Disabled or Reserved.
  • Is Master Pool: determine whether a subnet shall be marked in the system as the master pool
  • Use in entities: the entities that a subnet should be used in. Entities in the systems are locations, units and racks. A given subnet can be assigned to multiple locations, units and racks. Leave this field empty if you want a subnet to be available for all entities. This field is used in processes of automatic subnet assignment, e.g. during the order activation.
  • Description: enter any description of a pool

After filling in the necessary data click ‘Save Changes’.

Subnet’s Edition

In order to edit a given subnet, select it from a tree view and then click the ‘Edit’ button in this subnet’s summary:

ED_ipam2.png

The edition form does not include the fields concerning the type, address and mask of a subnet since they have been already filled in in the process of subnet creation. These fields cannot be altered as later errors with hierarchy could occur.

Subnet’s Division

The module provides a simple way to divide subnets. It shall be remembered that only subnets without child subnets can be subject to division. A subnet has to be the last one in the tree in order to be divided.

ED_ipam4.png

When dividing a subnet, the mask that shall be used in the process has to be chosen. If there are any devices assigned to a subnet, they will be unassigned from the parent subnet and assigned automatically to subnets created in the division process.

Device’s Assignment

Devices can be assigned only to the subnet that comes as the last element in a tree (without any child subnets). In order to assign a device to a given subnet, select this subnet and then choose the option ‘Assign Devices’ from the action menu available in the ‘Devices’ box:

ED_ipam5.png

An unlimited number of devices can be assigned to the subnet in the form:

ED_ipam6.png

After saving the changes, the list of devices assigned to the subnet is displayed in the ‘Devices’ box:

VLANs Assignment

VLANs can be assigned to all subnets. In order to assign VLAN to a subnet, select a given subnet in a tree view and then in the ‘VLANs’ box use the option ‘Assign VLANs’:

ED_ipam8.png

In the form you can assign an unlimited number of VLANs to the subnet.

ED_ipam9.png

The list of VLANs assigned to the subnet appears after saving the changes.

Subnet’s Deletion

Tick a given subnet in a tree view and click the ‘Delete’ button to remove it. It is important to remember that during the subnet deletion, all its child subnets are removed as well.

VLANs

Please note that management of VLANs is not based on the network layer of devices in the current system’s version. The automation of creation and deletion of VLANs is scheduled for implementation in the next releases.

VLANs Group’s Addition

The ‘VLANs’ section enables the management of groups and single VLANs in the system. Choose the ‘New VLAN Group’ option from the upper action menu in order to add a new group of VLANs:

ED_ipam11.png

Fill out the form as follows:

  • The name of a group
  • Range From: the number that specifies the first number of the VLAN in a given group, e.g. 1
  • Range To: the number that specifies the last number of the VLAN in a given group, e.g. 30
  • Is Private: determine whether VLANs created for a given group should be private or public
  • Description: enter any description of a group

Click ‘Save Changes’ once all necessary details are filled in. When the VLANs group is added, VLANs with the numbers from the previously specified range, e.g. Group Name 1, Group Name 2, Group Name X.

Single VLAN’s Addition

Choose the ‘Create VLAN’ option from the upper action menu in order to add a single VLAN.

ED_ipam12.png

Fill out the form as follows:

  • VLAN Number: the number of the VLAN
  • VLAN Name: the name of the VLAN
  • Group: the group that the VLAN belongs to
  • Assigned Devices: devices assigned to the VLAN, an unlimited number of devices can be selected
  • Assigned Subnets: subnets assigned to the VLAN, an unlimited number of subnets can be selected
  • Is Private: determine whether VLANs created for a given group should be private or public
  • Description: enter any description of a group

After completing the form click ‘Save Changes’.

VLANs Management

The ‘Summary’ icon available in the ‘Actions’ column has to be chosen to view the summary of a given VLAN. You will be automatically redirected to the summary page that contains basic information on VLAN along with the list of devices and subnets assigned to it.

ED_ipam13.png

Click ‘Edit VLAN’ in the upper action menu to proceed with VLAN edition. You can freely alter the data on a chosen VLAN by assigning or unassigning devices and subnets in the edition form. In order to delete the VLAN, choose the ‘Delete VLAN’ action from the upper menu. Keep in mind that all devices and subnets will be automatically unassigned from the VLAN after its deletion.

Subnets Provisioning In The Ordering Process

If IP Address Management module is enabled, you can define the number of additional IP addresses that a client shall receive upon the orer placing. To this end, use the field ‘Additional IPs’ (subnet mask) that determines the mask of a subnet in the form, e.g. /27, /30. When moving to the summary of a given order, in the ‘Service Configuration’ box you can configure the subnet that shall be assigned to a device during the order acceptace.

ED_ipam14.png

Find the ‘Configure Now’ button next to the field ‘Additional IPs’ (subnet mask) if you want to configure a subnet to be assigned.

ED_ipam15.png

If you do not configure the subnet that shall be assigned to a device, the system will attempt to find a free subnet with a previously defined mask in the process of the order acceptance. If such a subnet is detected, it will be automatically assigned to the device. In the opposite case, the entry on the failure of the subnet’s assignment operation will appear in the ‘Provisioning Log’ section.

IP Addresses

This section containts the list of all single IP addresses used in the system. IP adresses are fetched on the basis of the ‘IP Address’ and ‘Additional IP Addresses’ fields for all devices in the system. The section uses the caching mechanism to make the search process faster and more efficient for the administrator. Cache can be updated either automatically, after the deletion of IP address from the table, or manually – by pressing the ‘Refresh Cache’ button in the upper ‘Actions’ menu.

ED_ipam16.png

All data available in this section can be easily filtered using the following fields:

  • IP Address
  • Device
  • Address Type (IPv4, IPv6)
  • Type (Primary, Additional)

ED_ipam17.png

It should be noted that the following actions are taken during the attempt of the IP address deletion:

  • If the address is of ‘Primary’ type: the value of the ‘IP Address’ field for a given device is removed, the device then appears in the system without the main IP address
  • If the address is of ‘Additional’ type: such addresses are parsed from the ‘Additional IP Addresses’ field for a given device. For instance:
    • the value of the ‘Additional IP Addresses’ field of a device is: 192.168.10.10, 192.168.10.11, 192.168.10.12
    • the IP address 192.168.10.11 of Additional type is deleted in IP Address Management module
    • the new value of the ‘Additional IP Addresses’ field of a device is: 192.168.10.10, 192.168.10.12

Once the IP address is deleted the caching mechanism is reloaded automatically.
