Orbi RBR20 DHCP list order or Import/Export for modifying

Hi,

 

So I have a RBR20 system with 3 satellites and the DHCP reservation is driving me crazy. I split IP addresses into blocks IE a family of smart devices will start at a different "10" to others and family members will have their own block of "10"s (ie x.x.x.10 - x.x.x.19, x.x.x.31 - x.x.x.39)

 

The DHCP list only lists reservations in the order they were added to in order to add a new device I have to look through it manually and see what addresses are free to add something to that group. In addition I cant find an export option so I can have an external list that I could sort or reference, the only other option is me manually creating an excel file to reference which seems just rediculous and a waste of time.

 

Is there no way to sort the DHCP list by ascending order or IP or at the very least export the list? It would be even better if you could export and edit but I'm not hoping for too much other than avoiding the nightmare of adding a device in an organised system!

 

I must note we have 80-90+ smart devices of various types (lights, tv's, etc) and I like to lock down everything so its not a simple task.

 

Thanks!

  • Orbi systems doesn't support the export of that kind of configuration. 

     

    You might see if there is a method to maybe modify a .conf file under telnet.

    As FURRYe38 pointed out, Orbi is one of the few (only?) Netgear routers that provides terminal access.  From the Orbi "debug" page (http://orbilogin.net/debug.htm - login with the web credentials "admin" and password), check the box "Enable Telnet" toward the bottom of the page.

    Use a telnet client that can capture the results.  (I use PuTTY which has a "log" option to record all printable characters to a file. PuTTY is free for Windows & Linux (not Mac)

    Telnet into the router with the usual admin credentials, and type this command:

    nvram show | grep reservation*

    This will dump out the IP reservation table (with a couple of other lines that include "reservation".

    Paste the results into a file and sort.  Alas, sorting is not "smart".  i.e. 10, 11, 12, come after 1 and 2 comes after 19.  3 comes after 29, etc. Each line contains the MAC address and assigned IP address.

     

    Hope this helps
