All DHCP servers listed under the ProVision DHCP Tab will be available to select and attach to the Group. They are identified by their resource ID number, so if necessary, check the server's resource ID number in the resource information Gadget.
Select the desired server from the "Attach Server" selector, then click "Attach". The server is now attached to the group and available for pushes.
If needed, a server may be removed from a DHCP Group by clicking the "Detach" button. |

Step 5: Link Pools to DHCP Groups
| Expand |
|---|
From the Existing Pools list under the DHCP Pools section, click the Action Menu (gear icon) for the pool you wish to link to a DHCP Group. From there, click "Link to Group".
If multiple DHCP Groups exist, a dialog box will pop up for you to select the desired Group to link the pool to. Select the DHCP Group, then click "Confirm" to add the pool to the Group.
Once linked, the DHCP Pool will show under the "Linked Group Pools" area of the DHCP Pool section. From here, if desired, you may remove the pool from the group by clicking the Action Menu and "Remove Link".

Step 6: Push the DHCP Group
| Expand |
|---|
Lastly, click the "Push" button for the DHCP Group to push the linked pool(s) for the Group to the linked DHCP Module, and then push all DHCP servers linked to the Group.
While pushing, a status box will appear to show status and any errors, if applicable. |

In this gadget area, you may enter in the information that will be used for ProVision to communicate to the DHCP Server.
Server Details
Server details and advanced options may be entered under this portion of the gadget.

A note on the Server Command: Config Test option: This command is run after the newly-written DHCP Config file has been transferred to the server but before the server is restarted. Due to the wide variety of DHCP install configurations that can arise on different systems, it is best if the Config Test option is as explicit as possible. For example: sudo /usr/sbin/dhcpd -t -cf /etc/dhcp/dhcpd.conf This command explicitly requests the DHCP daemon start in test-only mode (-t) with a specific config file (-cf). This config file should be the location supplied in the "DHCP Config File Path" section. |
...
Scan Server provides a "Scan Now" button, which scans the DHCP server and returns found IPs under DHCP Pools.
The returned IPs are divided by Pools and IPv4/IPv6. Returned fields include MAC address, IP address, and name. The percentage utilization of IP space out of the available DHCP Pool space is also included at the top of the list.
If the scan is unable to be completed, an error message will appear in the DHCP Management section.
...
The Action menu for Linked Pools will show the option to Remove Link from Pools.
Additional edits may be made to pools by clicking on the Pool name. This allows the Pool name, assignment, and lines to be changed. Be sure to hit "Save" after making changes.
DHCP Pool Search:
Both Linked and Existing DHCP pools have field-specific search options to filter the DHCP pool list(s). Select the search term type from the dropdown list, type the search term in the search box, then hit the "Search" icon.
For both Linked and Existing pools, search terms include:
...
For Existing Pools, additional filter terms may be included to further filter the IP search by Region or assigned Resource.
After entering your search terms, click the "Search" icon, and the pool list will filter to the results.
...
For Smart Assign: select IPv4 / IPv6, Mask, then optional Region, Resource assignment, Domain - VLAN, and IP Rules criteria, add free lines if desired, then click "Add Pool".
For Direct Assign: select IPv4 / IPv6 and enter the block in CIDR format, add free lines if desired, then click "Add Pool".
Create a New DHCP Pool - Host

For Smart Assign: select IPv4 / IPv6, then optional Region, Resource assignment, Domain - VLAN, and IP Rule criteria, add free lines if desired, then click "Add Pool".
For Direct Assign: select IPv4 / IPv6 and enter the block in CIDR format, add free lines if desired, then click "Add Pool".
Current Pushed Configuration
Expanding "Current Pushed Configuration" allows you to view the detailed text (read-only) of the last sucessfully successfully pushed configuration.
Current Pushed Configuration does not reflect any un-pushed changes or failed pushes.
Saving/Pushing DHCP Server Configurations
...
When you Push a Configuration (by clicking "Push Configuration") the configuration is automatically saved.
Working with the DHCP Customer Configuration Gadget
The DHCP Customer Configuration Gadget allows users to assign APNIC IP aggregates to the DHCP server pools and generate DHCP Server Configuration changes.
These configurations are then sent to the associated DHCP server Management Gadget as "Unpushed Configurations", where they may be held until a manual or schedule push occurs.
Setting up the DHCP Customer Configuration Gadget
Before using the DHCP Customer Configuration Gadget, the following should be set up in ProVision:
- The associated DHCP server should be created in ProVision and set up in the DHCP Management Gadget or DHCP Tab - DHCP Servers list (See: DHCP Tab).
- Add the DHCP Customer Configuration Gadget to the desired Section. You may want to create a specific "DHCP Customer" Section for DHCP customer entries (See: Customizing Sections).
- Have, or set up IPAM Aggregates with subassignable blocks APNIC Aggregates for DHCP use from the IPAM Tab with the desired IP space type, RIR, Region(s), Tags, and any desired VLAN criteria. Regions are a required field when assigning IPs from the DHCP Customer Configuration Gadget. Any APNIC aggregate may be used for DHCP, so you may want to create a "DHCP" IPAM Tag to help denote the desired aggregate(s).
- If you are planning on Direct Assigning the DHCP blocks in the Customer Configuration Gadget, ensure that the desired blocks in the DHCP are split to individual /32 or /128 size. Smart Assign and Smart Browse will automatically split the block to assign the correct size.
Using the DHCP Customer Configuration Gadget
Step 1) Link the Gadget with the desired DHCP Server
Step 2) Assign IP's for Pools from DHCP Aggregates
Step 3) Set up configuration information - add Option 82 Elements, Circuit ID, and notes. Use the "Preview" field to confirm the accuracy of the data, and select the status as "Activate" or "Terminate".
Once saved, the updated configuration will be sent to the DHCP Management Gadget.
Step 4) an An admin user may manually push the updated configuration from the DHCP Management Gadget, or use a a scheduled DHCP push task to automate the pushes.
See Gadgets - DHCP Customer Configuration for more details.
